Additional Nursing Flashcards

 


 

Cards

Term

1. Bile Acid Sequestrants

Definition

Action: Bind bile acids in the intestines with cholesterol so that the molecules are too big to absorb and get eliminated through stool.

S/E: Nausea, vomiting, diarrhea, constipation, bloating

Nursing considerations:

  • powdered-need to dilute
  • affects absorption of other drugs (take 2hrs before or 4hrs after
  • may need to tak vitamin supplements
  • need to be cautious with patients with GI problems
  • Adequate fluids and "bulk" in the diet can help with GI problems.
Term
2. Fibric Acid
Definition

Action: unknown, but result is decreased production of triglycerides, lower VLDL, elevated HDL.  May cause slight increase in LDL

 

S/E: Rash, Gallstones, muscle pain or weakness

 

Nursing considerations:

  • Given with meals to decrease GI symptoms
  • Monitor closely with patients that are on blood thinners (can increase effect)
  • Muscle pain and weakness can be increase when patients are taking statins as well.
Term
3. Nicotinic Acids
Definition

Action: unknown but often used with other meds.  Causes lower VLDL, LDL, increased HDL and triglycerides.

 

S/E: GI problems, Gout, flushing, pruritis, Hyperglycemia, Hepatotoxicity.

 

Nursing considerations:

  • 1500-1300mg dose for cholesterol vs 25mg as vitamin
  • take with meal or after with cold water
  • Most troublesome side effect is the pruritis and erythemia (can take Aspirin 30 min prior to help)
Term
4. HMG-CoA reductase inhibitors (statins)
Definition

Action: inhibits the enzyme that is part of the process of cholesterol production.  Lowers LDL, triglycerides, increases HDL.

S/E: Indigestion, cramping, flatulence, constipation, myopathy (muscle pain,

weakness), liver dysfunction.

Nursing considerations:

  • Taken at bedtime because that is when cholesterol is manuf. except for Lipitor and Crestor.
  • Patients with known liver disease would either not be put on this drug or will be monitored carefully.
Term
5. Cholesterol absorption inhibitor (Zetia)
Definition

Action: Decreases absorption of cholesterol through the intestines.  Lowers LDL, triglycerides and increases HDL.

S/E:Joint pain, back pain, diarrhea, sinusitis, sometimes headaches, chest pain, dizziness if used with statins.

Nursing considerations:

  • Do not take with bile acid sequestrants
  • Caution in patients with liver/kidney problems
  • Can be taken with other lipid medications. 
Term
Antilipemics (5)
Definition
  • Bile Acid Sequestrants
  • Fibric Acid
  • Nicotinic Acid
  • Statins
  • Zetia
Term
Antihypertensives (9)
Definition
  • Diuretics
  • Beta Adrenergic Blockers
  • Calcium Channel Blockers
  • Angiotensin Converting Enzyme (ACE) Inhibitors
  • Angiotensin II receptor blockers (ARB)
  • Aldosterone receptor blockers
  • Central Alpha2 Agonists
  • Arterial Vasodilators
  • Alpha Adrenergic receptor agonists
Term
1.a. Thiazide Diuretics
Definition

Action: pulls water/sodium back into vascular space, increases urine production

S/E:  hyperglycemia, vasodilation, electolyte imbalances, gout, nausea, vomiting, diarrhea

Nursing Considerations:

  • Will cause loss of potassium and magnesium
  • Has effect on hypoglycemic agents
  • Contraindication in patients with renal failure
Term
1. b. Loop Diuretics
Definition

Action: Inhibits sodium/water resorption

S/E: nause, increased urination, hypotension, ototoxic (if given IV push to fast).

Nursing Considerations:

  • Take with food to decrease nausea
  • Do not give at bedtime because of increased urination
  • Will cause potassium loss-hypokalemic, will need to be on potassium supplement.
  • Monitor I&O, and electrolyte levels.
  • Monitor carefully at the start of therapy-patient will be more hypotensive at the beginning
Term
1. c. Potassium Sparing Diuretics
Definition

Action: reduces sodium (water) resorption but spares potassium.  Weaker than other diuretics

S/E: By itself-kyperkalemia, photo sensitivety, rash, dizziness, GI problems.

Nursing Considerations:

  • Watch electrolyte levels
  • Monitor for symptoms of agranulocytosis (rash, fever, sore throat)
  • Monitor vitals and I&O
Term
2. Beta Adrenergic Blockers
Definition

Action: Selective (heart) Non-selective (heart & lungs) decreases L ventricle contraction, slows heart rate, decreases renin release.

S/E: Dyspnea, wheezing, hypotension, bronchospasm, rebound hypertension if stopped, insomnia, depression, nightmares, angina, fatigue, sexual dysfunction, exercise intolerance.

Nursing Considerations:

  • Monitor HR and BP-check orders (may have an "...if less than 60 hold medication)
  • Selective beta blockers can have respiratory effect at higher doses but unlikely.
Term
3. Calcium Channel Blockers
Definition

Action: Limits the amount of calcium entering the cell (controls muscle contraction) can treat dysarrythmias. Dihydrophyredines- action on blood vessels. Nondihydropyridines- action on blood vessels and heart.

S/E: headache, dizziness, bradycardia, constipation, pedal edema, hypotension, reflex tachycardia

Nursing Considerations:

  • Patient may need to be placed on stool softeners
  • Vasodilation causes edema in lower extremities
  • Monitor BP
Term
4. Angiotensin Converting Enzyme (ACE) Inhibitors
Definition

Action: Blocks Angiotensin I from converting to Angiotensin II.  Inadvertly blocks Renin, vessels remain vasodilated, reduction in vascular resistance, increased sodium/water loss.

S/E: cough (persistant), headaches, dizzyness, hypotension (right at the start of treatment)

Nursing Considerations:

  • Cough may be bad enough to stop therapy.
  • Monitor BP
  • Will need to ask for help getting up at the beginning of therapy.
Term
5. Angiotensin II receptor blockers (ARB)
Definition

Action: decreases peripheral vascular resistance.

S/E: Can cause angioedema(swelling face, throat), dizziness, diarrhea.

Nursing Considerations:

  • This would be the drug that patients are moved to if side effects of ACE inhibitors don't work.
Term
6. Aldosterone receptor blockers
Definition

Action: prevents aldosterone from binding to receptors in the kidneys, reduces sodium and water retention.

S/E: headache, dizziness, hyperkalemia, nausea

Nursing Considerations:

  • fairly new classification
Term
7. Central alpha2 agonists
Definition

Action: decreases sympathetic effect on vessels, decreases norepinephrine and epinephrine, decreases cardiac output.

S/E: drowsiness, dizziness, bradycardia, rebound hypertension, can develop edema from sodium/water retention.

Nursing Considerations:

  • Not used much anymore.
Term
8. Arterial Vasodilators
Definition

Action: relaxes the smooth muscle of the arteries (dilates)

S/E: tachycardia, palpitations, headache nasal congestion, fluid retention, decreased kidney perfusion, edema.

Nursing Considerations

  • Not used much, except for in emergencies
  • Hyperstat and Nipride  have immediate actions with 2 minute half-life
  • Light sensitive (bottle has to be wrapped in aluminum foil.
  • Patient needs constant BP monitoring with arterial line.
  • May cause apreapism (sustained, painful erection)
Term
9. Alpha adrenergic recepter agonists
Definition

Action: Blocks sympathetic receptors, vasodilation

S/E: nausea, drowsiness, edema, nasal congestion, orthostatic hypotension.

Nursing Considerations:

  • Not typically a first line drug-low effectiveness in reducing CV complications.
  • Monitor vital signs and urine output.
