NCLEX Review Shownotes:

Understand that the Nervous system includes the Central Nervous System (CNS), the Peripheral Nervous Sytem (PNS) and the Autonomic Nervous System or the (ANS).

When I say the CENTRAL NERVOUS SYSTEM, We can simplify at as the BRAIN and the SPINAL CORD.

The PERIPHERAL NERVOUS SYSTEM on the other hand, contains the CRANIAL NERVES and the SPINAL NERVES.

  • WHEN WE TALK ABOUT THE AUTONOMIC NERVOUS SYTEM, WE ARE BASICALLY TALKING ABOUT THE “SYMPATHETIC” (FIGHT OR FLIGHT) SYSTEM OR THE “PARASYMPATHETIC” SYSTEM.
  • .THE BASIC COMPONENT OF THE NERVOUS SYSTEM IS THE NERVE CELL OR NEURON

NEURON

– is the primary component of the nervous system.

– it is composed of cell body (gray matter), axon and dendrites.

BRAIN  (Central Nervous System: Brain and Spinal Cord).

CEREBRUM- Outermost area (cerebral cortex) is gray matter, deeper area is composed of white matter

  • TWO HEMISPHERES: LEFT AND RIGHT AND EACH HEMISPHERE IS DIVIDED INTO TWO LOBES.

FRONTAL LOBE

  • PERSONALITY, BEHAVIOR
  • HIGHER INTELLECTUAL FUNCTIONING
  • BROCA’S AREA: (MOTOR SPEECH AREA)

PARIETAL LOBE

  • POSTCENTRAL GYRUS: REGISTERS SENSATION (TOUCH, PRESSURE)
  • INTEGRATES SENSORY INFORMATION

TEMPORAL LOBE

  • HEARING, TASTE, SMELL (HINT: LOCATION OF EARS – CLOSE THE TEMPLES)
  • WERNICKE’S AREA: SENSORY SPEECH AREA

Peripheral Nervous System- composed of Spinal Nerves (31)

Autonomic Nervous System- part of the Peripheral Nervous System

  • REGULATES FUNCTIONS OCCURRING AUTOMATICALLY IN THE BODY.
  • ANS REGULATES SMOOTH MUSCLE, CARDIAC MUSCLE AND GLANDS.

IT IS NOT NECESSARY TO KNOW EVERY PHYSIOLOGY FOR EVERY SINGLE PART OF THE BRAIN.  BUT JUST IN CASE WE END UP GETTING LOW LEVEL QUESTIONS ON THE EXAM, THEN IT IS IMPORTANT THAT WE UNDERSTAND THE BASIC CONCEPT AND FUNCTION OF EACH AREA. IT WOULD ALSO BE A GREAT IDEA TO KNOW THE CRANIAL NERVES.

Quick NCLEX Overview:

EYE AND EAR DISORDERS

GLAUCOMA

Glaucoma: there is an increased of intraocular pressure in the eye.

There are two types:

  1. OPEN ANGLE GLAUCOMA OR “PRIMARY” GLAUCOMA
  2. PRIMARY ANGLE GLAUCOMA.

Open angle glaucoma is slow in onset and chronic, while the primary angle glaucoma needs immediate treatment.

Open Angle Glaucoma

Bilateral

Acute Angle-closure Glaucoma

Unilateral

TREATMENT

Beta Adrenergic Blockers

Cholinergic Agents (Pilocarpine) ♣ (Make sure to know this for the NCLEX)

AVOID ANTICHOLINERGICS (Atropine)

NCLEX Review of the Urinary System

urinarynclexreview2

   Show Notes:

An NCLEX Review of the Urinary System: We will go over the major diseases that you most likely encounter in the NCLEX Exam.

The Urinary System

– is a vital system in the body that enables us to produce, store and eliminate urine.

MAINLY COMPOSED OF:
– the Kidneys
– the Prostate
– the Ureters
– the Bladder
– the Urethra

Although it is not necessary to have the physiology of each anatomy committed to your memory, it is very important to understand the concept and function of each.

DIAGNOSTIC TESTS WITH THE URINARY SYSTEM:

URINANALYSIS  

Very important to remember these values for the NCLEX.

BUN Level            10-20 mg/dl
Creatinine Level            0.5- 1.5 mg/dl
Calcium                 9- 11 mg/ dl
Urine Specific Gravity        1.003- 1.030

ELECTROLYTE IMBALANCE

Hyponatremia (decreased sodium)
Muscle weaknes, Headaches
Fatigue, confusion, vomiting, coma

Hpernatremia (increased sodium)
Tachycardia, dry mucus membrane
decreased urinary output

Hypokalemia (decreased pottasium)
Anorexia, nausea, vomiting
abdominal distention

Hyperkalemia (increased pottasium)
Irritability, nausea and vomiting
diarrhea

Hypokalcemia (decreased calcium)
osteoporosis, fractures, muscle spasms
tetany, n & v, vomiting.

Hypercalcemia (increased calcium)
Renal calculi, coma, arrythmias, decreased reflex

pkdnclex

POLYCYSTIC KIDNEY DISEASE

nclexnephrotic2

NEPHROTIC SYNDROME

GLOMERULONEPHRITIS/ PYELONEPHRITIS

nclexcalculireview

Urinary Calculi/ Ur0lithiasis

CHRONIC RENAL FAILURE

STAGES OF CHRONIC RENAL FAILURE

Stage 1 Diminished Renal Reserve

  • – renal function is reduced, but no accumulation of metablic wastes occurs.
    – the healthier kidney compensates for the diseased kidney
    – The ability to concentrate urine is decreased
  •   ♦ Results in nocturia and polyuria

– Stage 2 Renal Insufficiency

  • – metabolic waste begin to accumulate in the blood, because affected nephrons can no
    longer compensate.
    – responsiveness to diuretics is decreased, resulting in Oliguria and edema

Stage 3 End Stage Renal Disease.

  • – excessive amount of metabolic wastes such as
    urea and creatinine accumulate in the blood.
    – kidney is unable to maintain homeostasis
    – treatment is by dialysis

Metabolic Changes
– Urea and Creatinine
– Sodium
– Pottasium
– Acid Base Balance
– Calcium and Phosporus

Cardiac Changes
– Hypertension
– Hyperlipidemia
– Heart Failure
– Uremic Pericarditis

INTERVENTIONS
– It is important to monitor renal, respiratory and cardiovascular status and the fluid balance.

REMEMBER FOR NCLEX
– Patient with Chronic Renal Failure would have

  • ♣ UREMIA, ANEMIA AND ACIDOSIS

DIALYSIS:

Peritoneal Dialysis:

♣ Complication: can include Peritonitis

Hemodialysis:

♠ Pt. may use external shunt or surgically constructed internal arterivnous fistula (long-term)

Most common cause of renal failure is *poorly controlled diabetes & Hypertension.

Dopamine= can enhance renal perfusion and elevate blood pressure.

♠ Ways to control monitor kidney function:

  • Monitor I and O
  • Monitor Lab Values
  • Specific Gravity
  • BUN and Serum

NCLEX Pharmacology

A Quick Review on Pharmacology

♣ Show Notes

NCLEX Review on Pharmacology

The fact is that pharmacology will always be a big part in your NCLEX Exam, and can be a huge catalyst in whether you pass or fail your NCLEX Exam.  It is quite important for us to focus a lot on the content that pertains to medications, if we are reviewing for the NCLEX.  The NCSBN (who is responsible for developing the NCLEX Exam) defines the category of Pharmacological and Parenteral Therapies as a sub-category within the Physiological Integrity area (of the exam)  in which the nurse is basically providing care related to the administration of medications and parenteral therapies.

To be more specific, Pharmacological and Parenteral Therapy has contents that  includes but is not limited to:

  • Adverse Effects/Contraindications/Side Effects/Interactions
  • Expected Actions/Outcomes
  • Medication Administration
  • Blood and Blood Products
  • Parenteral/Intravenous Therapies
  • Central Venous Access Devices
  • Pharmacological Pain Management
  • Dosage Calculation

First, I want to take a step back and look at Pharmacology from a technical sense and look at it more in depth.

What is Pharmacology?

♠ PHARMACOLOGY

Pharmacokinetics– The study if how drugs are being absorbed, distribuited, metabolized and excreted by the body.
Pharmacodynamics– is the study of how drugs are being used by the body.
Pharmacotherapeutics– the study of how the client responds to the particular drugs.

What’s in a drug name?
Chemical Name:
This tells you the chemical makeup of the drug.
Generic Name
This name is given by the company that developed the drug.
Trade Name
This is the name given to the drug by the company in which the medication originated.

The Seven Rights of Administering Drugs

  • Right Client
  • Right Route
  • Right Drug
  • Right Dose
  • Right Amount
  • Right Time
  • Right Documentation
  • Right to refuse treatment

Any drug can have a CHEMICAL NAME, A GENERIC NAME AND A BRAND OR TRADE NAME.

  • The generic name of a drug is suggested by the manufacturer, and accepted by the international committee.
  • How the drug is being affected affects the body and the patient’s response is called the effect.
  • Efficacy refers to the degree to which a drug is able to induce it’s maximal effects.
  • Adverse Effect is any unexpected or unintended response to a therapeutic use of a drug, it is also called side effect.

During this review, I want to focus specifically towards the drugs that is mostly in patients with hypertension.

DRUGS USED WITHIN THE CARDIAC SYSTEM

hypmeds

Cardiac Pharmacology

♣ Pharmacology Drugs for Hypertension:

DIURETICS

  • – Helps get rid of the sodium and fluid in the body.
  • – Used to lower the blood pressure.
    – Promotes the excretion of sodium and water
    – Diuretics interferes with the sodium absorption in the kidney.
    – Increases the urine output.  Decreases the preload and afterload..

If the patients blood pressure drop to low, it is important to give IV fluids to pt.

LETS GO OVER THE CATEGORIES OF DIURETICS ♠

♦ TYPES OF DIURETICS

♣ POTTASIUM SPARING DIURETICS

It promotes the excretion of soduium and water, while the retention of pottasium

Used for:

  • Hypertension
  • Edema
  • Hyperaldosteronism
  • Hypokalemia

Medication:

  • SPIRONOLACTON (ALDACTONE)
  • AMILORIDE (MIDAMOR)
  • TRIAMTERENE

Now lets go to the side effects:

First, of course the person can have too much potassium or HYPERKALEMIA:

Signs of HYPERKALEMIA

  • irregular heartbeat
  • nervousness
  • tingling in hands and feet
  • shortness of breath
  • tiredness or weakness

OTHER SIDE EFFECTS:

  1. Nausea and vomiting
  2. Cramping and diarrhea
  3. Dizziness & headache

Loop Diuretics

  • BUMETANIDE (BUMEX)
  • FUROSEMIDE (LASIX)

Osmotic Diuretics

MANNITOL

  • Thizade Diuretics

HYDROCHLOROTHIAZIDE (HYDRODIURIL)
CHLOROTHIAZIDE (DIURIL)
CAUSES THE DEPLETION OF SODIUM AND WATER.
♣ CAN INDUCE HYPERGLYCEMIA

Very Important for the NCLEX:

SIDE EFFECTS OF DIURETICS

  • Frequent urination
  • Electrolyte abnormalitie
  • Muscle cramps or weakness
  • Blurred vision
  • confusion
  • headache
  • increased perspiration (sweating)
  • restlessness

BETA (ADRENERGIC)  BLOCKERS

– Helps lower blood pressure, puls rate and cardiac output.
– Can be used to treat headaches.
– Can be used to treat glacauma and prevent myocardial infarctions.
– Acts on the system, by blocking the symathetic vasomotor response.

For the NCLEX, try to remember that the syllable for beta blockers is usally (olol).

SIDE EFFECTS:

  • Orthostatic hypotension
  • bradycardia
  • nausea and vomiting
  • diarrhea

NOTE: Some of the symptoms may MASK signs of Hypoglycemia

♠ HYPOGLYCEMIC SYMPTOMS

NURSING INTERVENTIONS FOR CLIENTS TAKING BETA BLOCKERS:

Make sure that you monitor the client’s blood pressure, heart rate and rhythm, before administering the beta blocker.  Monitor the client for signs of edema.  The nurse should also assess the lungs sounds for signs of rales and ronchi.  When patient are taking beta blockers, it is also very important to monitor the changes in lab values such as (protein, BUN and creatinine) which can indicate nephrotic syndrome.  Nursing teaching for the NCLEX would include: Teaching the Client to rise slowly (ORTHOSTATIC HYPOTENSION) * (A SAFETY ISSUE), report any signs of bradycardia, dizziness, confusion depression or fever.  It is also very important to taper off the medication properly.

Cardiac Pharmacology

♣ Calcium Channel Blockers

  1. – PREVENTS THE MOVEMENT MECHANISM OF CALCIUM WITHIN THE CARDIAC SYSTEM.
  2. – THEREFORE DECREASING THE CARDIAC WORKLOAD, AND CARDIAC MUSCLE CONTRACTILIY.
  3. – MEDICATIONS INCLUDE THE “DIPINE” : DILITAZEM (CARDIZEM), AMLOPIDINE (NORVASC), NEFEDIPINE, NICARDIPINE.
  4. – USED TO TREAT ANGINA.

How to Pass the NCLEX Exam

pass NCLEX Review

Show Notes:

Now I have been getting plenty of questions lately and most of these questions pertains obviously mostly on how to pass the NCLEX Exam.  So, what I did was I did some research outside of the actual “Nclex review content” scenario  and took a step back and really look at the reasons why some people passed there NCEX Exam, the first time they take it.  Its quite obvious that the answer for that would be that the ones that pass on the first time really did studied hard invested plenty of time, energy and effort into the to the review while others, well…  Let me ask you this, have you noticed how some people are just really good in taking exams?. There are usually those people in our lives that just really good at taking exams.  On the outside it doesn’t seem like they’re really are studying that hard or investing that much time (which can be true) or we might not really know how much they’ve studied or how much time they invested yet at the end of the day they still pass their exam on the first try…

Sometimes it boggles our minds and we can even get quite jealous.  Now I think for the most part these people really did invest plenty of the time and energy and resources in passing this exam (which I personally did, and it paid off ) but I also believe that these people do have a good amount of test taking skills because for me personally I really did invest plenty of time, effort, energy and sacrifice in order to pass the NCLEX Exam the first time I took it about three years ago.  Anyhow,  I also believe that these people unconsciously were able to adapt to a certain strategic approach on learning that worked on their own specific learning styles.

I did my own research on most of these test takers and found out that these people are more analytic in their review methods than I thought.

nclex study review pass guides

And this is what I have learned:

You need to learn a deeper level way of studying that is complimentary to our learning style.  When we just try to memorize words it’s what researchers have called the, “shallow level of processing,” basically you are just looking at the words and trying to memorize them without making any connections or understanding (in depth) by looking and analyzing the bigger picture.  Instead, we need a more “deep level processing” way of reviewing the NCLEX.  This can be accomplished by trying to connect it with our own experience and also understanding more in depth the NCLEX Review Contents.

What can really enhance the deeper level processing way of reviewing for the NCLEX Exam  is by allowing your brain to match your learning style whether you are an (auditory learner, visual learner or a tactile learner).  So this includes looking at NCLEX Review Videos (HERE IS THE LINK), maybe even playing an AUDIO NCLEX Review CD in your car while driving (HERE IS THE LINK) or just trying to connect, what you are learning with your everyday experience.

Attention and Interest is an important subject when studying for the NCLEX.  Sometimes, reviewing for the NCLEX exam can just become too tedious and boring.  There are plenty of times when we are reading unconsciously just word after word without actually retaining and understanding the content (which is counter productive).

Therefore, there is no reason for our NCLEX Review not to be fun and interesting (while learning at the same time).  We need to look at other ways such as media (audio and video) and websites to enhance our NCLEX Review.

Don’t settle for boring, check out some stuff below…  : )

Ultimate NCLEX Review on Medications Pharmacology

NCLEX Review Neurological Pharmacology

Neurology Pharmacology

Amyotrophic lateral sclerosis (ALS) NCLEX Review

NCLEX Review on Seizure

Meningitis NCLEX Review

Meningitis  (By: AllNursingNotes)

Lets take a quick look at Meningitis and what we need to know for the NCLEX.

Meningitis is simply:

– an inflammation of the meninges within the brain and spinal cord.

  • * Usually caused by Niesseria meningitidis, Group B Strep and Streptococcus pneumoniae

Again, the two main culprit for Meningitis are

  1. Niesseria meningitidis
  2. Streptococcus pneumoniae

Assessment findings on the patient:

  • * Positive Brudzinski’s Sign

– There is some neck stiffness that causes a patient’s hips and knees to flex when the neck is flexed

  • * Positive Kernig’s Sign

– With the patient lying flat, if the patient flexes a hip 90 degrees, and then attempts to extend the lower leg at the knee. Pain on extension is a positive sign.

  • Chills
  • Fever
  • Headache
  • Malaise

Diagnostic Evaluation:

  • Lumbar Puncture
  • Chest X rays

NCLEX Review on Bells Palsy

We are going  to look at NCLEX Review on Neurological Medications (Pharmacology)

To review neurological pharmacology for the NCLEX, it is very important to simplify and of course UNDERSTAND  Neuro medications.

NCLEX Review Neurological Pharmacology: Lets first look at the drugs that affects the PNS.  For the NCLEX, it is very important to understand that the Parasympathetic Nervous System is focused primarily on:

  • – Pupil Constriction (Miosis)
  • – Lacrimation
  • – Salivation
  • – Bronchoconstriction

PNS Medications can also decrease the Heart rate and stimulate gastric secretions.

We can divide the PNS Medications into 4 different groups:

  1. Cholinergic Agonists
  2. Cholinesterase Inhibitor
  3. Anticholinergics
  4. Dopaminergics

NCLEX Review on Cholinergic Medications

Cholinergic Drugs

– Is also called Cholinergic Agonist
– stimulates cholinergic receptors
– mimics acetylchoine

– Used for Urinary Retention (Bethanicol Chloride *Urecholine)

Remeber for the NCLEX, that when we talk about Cholinergic Medications we focus towards the PNS.

Cholinergic drugs produce the same effects as acetylcholine.

Remember for the NCLEX:
– Direct acting cholinergicd are contraindicated with patients with asthma, because it can cause BRONCHOSPASM.

Uses:
Cholinergic muscle stimulants are used to diagnose and treat myasthenia gravis

NCLEX Drugs:

  • ambenonium chloride (Mytelase)
  • edrophonium chloride (Tensilon)
  • neostigmine (Prostigmine)
  • piridogstimina (Mestinœn).

Cholinergic drugs are also used in control of glaucoma.

NCLEX Drugs:

  • demecarium (Humorsol)
  • echthiophate (Phospholine iodide).

Drugs:

  • Bethanecol Chloride
  • Pilocarpine (Pilocar) *used for glaucoma

Side Effects:

  • Headaches
  • Hypotension
  • Miosis
  • Diarrhea/Cramping
  • Increased Salivation (Dry Mouth)
  • Nausea and Vomiting

Anticholinergic Medications

– Is called Acetylcholinesterase Inhibitor

  • Inhibits ACh/ Acetylcholine.

– Is also called (Cholinergic Blockers)-
– Helps control the tremors-
– Used to help improve memory in pts. w/ Alzheimer’s Disease (Donezepil Hydrochloride).
– Diphenhydramine Hydrochloride (Benadryl)
– Benztropine Mesylate (Cogentin)
– Diphenhydramine Hydrochloride (Benadryl)

  • Side Effects
    – Salivation
  • – Sweating
  • – Flushing
  • – Headache
  • – Hypotension
  • – Bradycardia

 

Anti-Myasthenic Pharmacology NCLEX Review

– A good use for anti-cholinergic drugs would be for Myasthenia Gravis.

Anti-Myasthenic Medications
– relieves muscle weakness with myasthenia gravis.
– used to diagnose Myasthenia Gravis
– used to distinguish cholinergic crisis from myasthenia gravis.

NCLEX DRUGS:
– Ambenonium Chloride (Mytelase)
– Endrophonium Chloride (Tensilon)
– Neostigmine Bromide (Prostigmin)
– Pyridostigmine Bromide (Mestinon)

ANTICONVULSANTS 

NCLEX Review: Anticonvulsant Medications act upon the CNS or the Central Nervous System.  Anticonvulsant medications helps decrease the firing and inhibits the spread of nerve impulses which results in stabilization of abnormal cells.

The 4 Main Types of Anticonvulsant Medications to know for the NCLEX includes:

  1. Hydantoins
  2. Barbituates
  3. Benzodiazepines
  4. Succinimides

Carbamazepine (Tegretol):
– Can be used for Trigeminal Neuralgia
Used when no response to Lithium

Side Effects:
S/E: Sedation,
granulocytosis
aplastic anemia so
* Make sure to MONITOR the CBC in patient.

NX: monitor CBC and alert for fever/sore throat; birth defects

Valproic Acid: Valproate (Depakene, Depakote):
A psychiatric medication that is used w/manic or schizoaffective;

Other Uses for this psychiatric medication:

  • Generalized Tonic-Clonic Seizures
  • Myoclonic Seizures
  • Partial Seizures

Side Effects:
Severe/Fatal Hepatotoxicity, ↓ platelets, neural tube defects
NEURAL TUBE DEFECTS in Fetus

Clonazepam (Klonopin):
Benzodiazepine medication for acute mania, acute help while waiting
for Lithium effects to occur ƒ

S/E: Sedation, Anoxia, Disinhibition
effect

HYDANTOINS
– used to treat seizures.
PHENYTOIN (Dilantin)A medication usually seen on the NCLEX exam.
* Decreases the effects of birth control pills.

*Interacts with ALCOHOL.

Side Effects:

  • Dizziness
  • Drowsiness
  • Hypotension
  • Respiratory Depression

Patient with Bell’s Palsy can be given TYLENOL (Acetominophen)
If overdose, antidote for TYLENOL is Acetylcysteine (Mucomyst)

 

(Neuro Medications)Based on the 4 Neuromuscular diseases

NCLEX Review on Anti-Parkinsonian Medications
– releases dopamine
– restores balance of neurotransmitters acetylcholine and dopamine in CNS.
* Virtually all of the available drug therapies act to increase the level of dopamine in the brain.

– TWO TYPES:
1. Anticholinergic Medications
2. Dopaminergic Medications

Anticholinergic Medications (Cholinergic Blockers)
– Helps control the tremors
– Benztropine Mesylate (Cogentin)
– Diphenhydramine Hydrochloride (Benadryl)

Dopaminergic Medications
– Levodopa (Dopar)
– Carbidopa-Levodopa (Sinemet)

* Levodopa is contraindicates with patients with angle-closure glaucoma.

SIDE EFFECTS:
Nausea
Orthostatic Hypotension

Dopamine agonists.
Unlike levodopa, dopamine agonists don’t change into dopamine.
Instead, they mimic dopamine effects in your brain.

NCLEX DRUGS:

NCLEX Review: Neuromuscular Drugs used for Increased in ICP.

Mannitol (Osmitrol)

A loop Diuretic

  • is used to decrease cerebral edema during increased ICP.
  • It is an osmotic diuretic,
  • Electrolytes are also drawn into blood and excreted, so monitor for electrolyte imbalance
  • Hyponatremia is a life threatening side effect, causes seizures and death.
  • Maintain strict I&O.
  • Dobutamine (Dubutrex)
  • Norepinephrine (Levophed)
    – cardiac stimulants used to maintain cerebral perfusion during increased ICP.

Dexamethasone (Decadron)

  • Corticosteroid used to decrease inflammation surrounding a brain tumor
  • Used in medical management of meningitis.
  • Used post craniotomy for cerebral edema
  • Administer IV q 6 hours for 24-72 hours, change to oral a.s.a.p., taper dosage over 5-7 days
  • As with any steroid, fluid retention, increased sugar, lowed immune system
  • Common side effect nasal irritation, cardiovascular edema, hyperglycemia, cataract, oral candidiasis, impaired would healing
  • If using with Mannitol (makes electrolytes be excreted) (by the way the two together are contraindicated according to the book) add potassium-rich foods or supplement to diet.
  • Use good oral hygiene to prevent oral candidiasis

Phenytion (Dilantin)

  • Anticonvulsant – to reduce risk of seizures
  • Especially after supratentorial neurosurgical procedure (prone to seizures)
  • Used to prevent grand mal and complex partial seizures
  • During Ictal phase of seizure give ativan (lorazepam), then start dilantin
  • Life threatening side effects are cardiovascular collapse, Agranulocytosis, aplastic anemias, dermatitis (bullous, exfoliative, or purpuric), Steven-Johnson syndrome.
  • Common side effects gingival hyperplasia (swollen gums), give good mouth care.  Self care pt should brush, floss and massage gums after each meal.

therapeutic level is 10-20 mcg/ml

Do not stop drug abruptly, may precipitate status epilepticus.

Diazepam (Valium)

Antiseizure Medications: NCLEX Exam

  • Tegretol
  • Klonopin
  • Keppra
  • Luminal
  • Dilantin-Phenytoin
  • Topamax
  • Depakote

TYLENOL
– Check Direct Bilirubin to determine drug toxicity.

DEMEROL
– Check for Urinary Retention

ASPIRIN Intoxication

Cardiac Pharmacology

Cardiac System NCLEX Review

Urinary System NCLEX Review (By: AllNursingNotes)

Below shows the (Cardiac Drug Categories)

that correlates to each of the individual initials.

NCLEX Review on Cardiac Pharmacology

As you have learned in Nursing School, beta adrenergic blockers are drugs that help lower blood pressure, puls rate and cardiac output. Beta Blockers are an important set of drugs to know for the NCLEX. Sometimes, beta blockers are also used to treat migraine headaches an other vascular headaches. Beta blockers are also used to treat glaucoma and used to prevent myocardial infarctions. Try to remember that what beta blockers do is they act by blocking the symathetic vasomotor response. For the NCLEX, try to remember that the syllable for beta blockers is usally (olol).

Potential side effects of beta blocker that is necessary to know for the NCLEX would include: Orthostatic hypotension, bradycardia, nausea and vomiting, diarrhea and some of the symptoms may MASK HYPOGLYCEMIC SYMPTOMS.

NURSING INTERVENTIONS FOR CLIENTS TAKING BETA BLOCKERS: Make sure that you monitor the client’s blood pressure, heart rate and rhythm, before administering the beta blocker. Monitor the client for signs of edema. The nurse should also assess the lungs sounds for signs of rales and ronchi. When patient are taking beta blockers, it is also very important to monitor the changes in lab values such as (protien, BUN and creatinine) which can indicate nephrotic syndrome.

Nursing teaching for the NCLEX would include: Teaching the Client to rise slowly (ORTHOSTATIC HYPOTENSION) * (A SAFETY ISSUE), report any signs of bradycardia, dizziness, confusion depression or fever. It is also very important to taper off the medication properly.

Cardiac Glycosides

NCLEX Review on Hepatitis

Hepatitis is a very important topic in the NCLEX.

Hepatitis is basically a viral infection that causes  inflammation of the liver cells.

Classifications of Hepatitis Virus and its way of TRANSMISSION:

(If we look at the transmission: Hepatitis B and C are the only ones transmitted through blood and sexual contact).

Hepatitis A (transmitted through oral/fecal/water route)
Hepatitis B (transmitted through blood/drug use/sexual contact/childbirth)
Hepatitis C (transmitted through blood/drug use/sexual contact/childbirth)
Hepatitis D (transmitted through oral/fecal/water route)
Hepatitis E (transmitted through oral/fecal/water route)

Hepatitis A

– Incubation period usually lasts from 15-45 days.

– Transmitted primarily through fecal/ oral route.

– Prevention includes sanitation and handwashing.

– There is a vaccine available for Hepatitis A.

– Prevention against Hepatitis A includes:

  • Proper Handwashing
  • Avoidance of contaminated food and water
  • Recieving the HAV Vaccine

Hepatitis B

transmitted through blood to blood contact sexual contact or drug use (needles, razors).

– There is a vaccine available for Hepatitis B.

Hepatitis C

Hepatitis C is transmitted through blood to blood contact sexual contact or drug use (needles, razors)

– The patient can be asymptomatic and others are only diagnosed once abnormality is detected in the liver enzymes.

SYMPTOMS OF ACUTE HEPATITIS C

  • Fever
    Fatigue
    Loss of appetite
    Nausea
    Vomiting
    Abdominal pain
    Dark urine
    Clay-colored bowel movements
    Jaundice (yellow color in the skin or eyes)

Some of these symptoms can also be present on other classifications of Hepatitis* .

Keep in mind: ↓↓↓↓↓↓↓↓

Hepatitis B and Hepatitis C is connected with cirrhosis and liver cancer.

Blood and Blood Products before 1992 were not screened for Hepatitis.

Enzyme-linked immunosorbent assay (ELISA) is the initial screening test for clients suspected of infected of the Hepatitis C (HCV) Virus.

Liver Biopsy can also be used to confirm the diagnosis of Hepatitis.

Treatment most often used for Hepatitis C is a combination of two medicines, interferon and ribavirin.

NCLEX Review Cirrhosis

So what is cirrhosis and why is it very important to review for the the NCLEX ?

Cirrhosis is basically scarring of the liver.  It occurs when there is severe hepatic inflammation or necrosis.

Common causes of cirrhosis:

  • Alcohol
  • Hepatits C
  • Hepatitis B

Complications of Cirrhosis:

(It is very important to understand these complications for the NCLEX.)

Portal Hypertension

An increase in the pressure in the portal vein.  It is usually due to an obstruction of blood flow within the portal vein.

Ascites

– an accumulation of fluid within the peritoneal cavity.

– there will be retention of water and sodium in the body.

Esophageal Varices

– occurs when thin walled esophageal veins become distended from an increase in pressure.

Jaundice

– is caused by hepatic cirrhosis.  Develops because the liver cells cannot effectively excrete bilirubin.

Portal-Systemic Encephalopathy

– a manifestation by neurological symptoms

Physical Assessment

in patients with Cirrhosis:

  • Fatigue
  • Abdominal pain
  • Weight Loss
  • Asterixis

Laboratary Assessment:

There will be an increase in serum levels of (AST)/ Aspartate aminotransferase, (ALT) / Alanine aminotransferase and (LDH) / Lactate Dehydrogenase.

♣ Interventions:

– depends on the SYMPTOM and the COMPLICATION.

FOR ASCITES

  • Intervention for ascities includes *PARACENTESIS – if diet and drug management fails.

♠ PARACENTESIS

– The procedure is performed in the bedside.

It has happend to the majority of us.  It has happened to us in Nursing School, but we didn’t expect it to happen now, after we graduate from Nursing.  But it does, it is just part of the JOURNEY towards our Nursing Career.  For you, maybe its your first time taking the NCLEX, for others maybe the second time, or even maybe the third or fourth.  And you have now reached the epitome of stress, you felt like you have poured everything into passing this oh so “dreaded” exam that they call NCLEX.  And for the unfortunate one’s who have worked so hard, gave it their all but still come a little short and still FAIL, it is so tough to a point that you reach the point of…. BURNOUT. 

Now I am going to talk a little about STRESS, and how our AWARENESS and PRACTICE can help.  This is not only directed towards Nursing School and the NCLEX, but in the general sense of living a more happy fulfilled life.

I personally don’t believe that a stress-free life is possible. Stress is a response to challenges in life, and a life without challenges is too boring to contemplate. However, I do believe that most of the stress in our lives is unnecessary, and that it can be eliminated by taking some simple (and some not-so-simple) steps. It can’t be accomplished overnight — I’ve been eliminating stressors in my life for awhile now, and I’m still not done. But I think it’s a worthwhile goal.  I remember how stressful NURSING SCHOOL was.  As a matter of fact, it was at some point a “HELL” kind of experience for me.  The journey was tough, one in which it has affected my life: physically, emotionally, mentally and spiritually…. but in one sense, it has also made me become a stronger person.

 

Especially living in this Country, and the economic turmoil that we just had experienced, it can become overwhelming.  I think overcoming and understanding the stress involved with being in Nursing School and NOW… taking the NCLEX is more than just this experience.  Because I believe that as we start JOB HUNTING and start working as a nurse, there will be new stressors that we will encouter.  But these sources of stress can be eliminated with a little thought. Here’s how:

  1. Identify stressors. This is the most important step of all, as identifying the things that stress you out in your life is the first step towards eliminating them. Take 10 minutes to think about what stresses you out during the day. What weekly occurrences stress you out? What people, activities, things cause stress in your life? Make a Top 10 list, and see which of them can be eliminated, and start to weed them out. For those that can’t, find ways to make them less stressful.
  2. Procrastination. We all do this, of course. But allowing stuff to pile up will stress us out. Find ways to take care of stuff now (form a Do It Now habit) and keep your inbox and desk clear.
  3. Controlling. We are not the Master of this Universe. I know we sometimes wish we were, but acting as if we are is a sure way to get stressed out. Trying to control situations and people cannot work, and only serves to increase our anxiety when it doesn’t work. Learn to let go, and accept the way that other people do things, and accept what happens in different situations. The only thing you can control is yourself — work on that before you consider trying to control the world. Also learn to separate yourself from tasks and to delegate them. Learning to let go of our need to control others and the situations around us is a major step towards eliminating stress.
  4. Multitasking. Having multiple tasks going on at the same time might seem productive, but in actuality it slows us down from actually focusing on a task and completing it — and it stresses us out in the meantime.
  5. Avoid difficult people. You know who they are. If you take a minute to think about it, you can identify all the people in your life — bosses, coworkers, customers, friends, family, etc. — who make your life more difficult. Now, you could confront them and do battle with them, but that will most certainly be difficult. Just cut them out of your life.
  6. Simplify life. Simplifying, of course, is very important, at least to me personally. Simplify your routines, your commitments, your information intake, your cluttered rooms, the mass of stuff going on in your life … and have less stress as a result.
  7. Slow down. Instead of rushing through life, learn to take things slow. Enjoy your food, enjoy the people around you, enjoy nature. This step alone can save tons of stress.
  8. Help others. It may sound contradictory to add more tasks to your life by trying to help other people (you’ve got enough to do), but if you were to add anything to your life, this should be it. Helping others, whether volunteering for a charity organization or just making an effort to be compassionate towards people you meet, not only gives you a very good feeling, it somehow lowers your stress level. Of course, this doesn’t work if you try to control others, or help others in a very rushed and frenetic way — learn to take it easy, enjoy yourself, and let things happen, as you work to make the lives of others better.
  9. Relax throughout the day. It’s important to take mini-breaks during your work day. Stop what you’re doing, massage your shoulders and neck and head and hands and arms, get up and stretch, walk around, drink some water. Go outside and appreciate the fresh air and the beautiful sky. Talk to someone you like. Life doesn’t have to be all about productivity. You should also avoid using online activity too much as your de-stressing activity — get away from the computer to relax.
  10. Exercise. This is common advice for stress relief, and that’s because it works … but it’s also a stress prevention method. Exercising helps relieve the stress buildup, it gives you some quiet time to contemplate and relax, and just as importantly, it makes you more fit. A fitter person is better equipped to handle stress. Another important factor: being unhealthy can be a major stressor (especially once you have to go to the hospital), and exercise can help prevent that.
  11. Eat healthy. This goes hand-in-hand with exercise as a stress prevention method, of course. Become healthier and a major source of stress will disappear. Also, I’ve found that greasy food, for me, puts me in a worse mood and can contribute to stress levels immediately
