Exam 2 Prototypes Flashcards
diphenhydramine (Benadryl) Pharmacological Class
H-1 receptor blocker
diphenhydramine (Benadryl) Indications
Allergies motion sickness insomnia pruritus Parkinson's Disease
diphenhydramine (Benadryl) MOA
H-1 receptor antagonist
diphenhydramine (Benadryl) Contraindications
elderly more likely to experience delirium, dizziness, inc HR. Children more likely to have paradoxical excitation
diphenhydramine (Benadryl) Adverse Effects
drowsiness (develop tolerance to this), dry mouth, inc. HR (anticholinergic effects
diphenhydramine (Benadryl) Other Considerations
avoid concurrent use w/ other CNS depressants (opioids, alcohol, etc.)
fluticasone(Flonase) pharmacological class
corticosteroids
fluticasone(Flonase) Indications
allergic rhinitis, asthma(can be given as an inhaler)
fluticasone(Flonase) MOA
decreases inflammation in nasal mucosa
fluticasone(Flonase) adverse effects
burning sensation when spraying, epistaxis (nose bleed)
oxymetazoline (Afrin) Pharmacological class
sympathomimetic
oxymetazoline (Afrin) Indications
allergic rhinitis, nosebleeds
oxymetazoline (Afrin) MOA
alpha 1-adrenergic agonist (causes vasoconstriction of blood vessels in nasal mucosa and drying of mucous membranes)
oxymetazoline (Afrin) adverse effects
rebound congestion, dry/stinging nasal mucosa
atropine adverse effects
Dry mouth, constipation, urinary retention, tachycardia, blurred vision
atropine pharmacological class
anticholinergic
atropine indications
GI hypermotility, suppress secretions during surgery, symptomatic bradycardia, pupil dilation for exam, antidote for poisoning with nerve gas or organophosphates (insecticides)
atropine contraindications
Clients with glaucoma
atropine MOA
Blocks cholinergic (muscarinic) receptors, causing increased heart rate, decreased GI motility, mydriasis, bronchodilation, and decreased secretion from glands (salivation)
spironolactone pharmacological class
Aldosterone antagonist
spironolactone indications
Heart failure , edema with liver failure, HTN, hyperaldosteronism
spironolactone MOA
Inhibits aldosterone, increasing the secretion of water and sodium while decreasing the excretion of potassium
spironolactone adverse effects
Hyperkalemia, hyponatremia, diarrhea, gynecomastia
spironolactone nursing implications
Monitor urine output, BP, potassium levels; educate clients to avoid foods high in potassium or salt substitutes high in potassium
spironolactone therapeutic class
Antihypertensive, drug for edema
furosemide therapeutic class
Drug for heart failure, hypertension
furosemide pharmacological class
Loop diuretic
furosemide indications
Heart failure, renal failure, hepatic cirrhosis, pulmonary edema, edema, HTN
furosemide MOA
Inhibits reabsorption of sodium and chloride in the ascending loop of Henle. Results in increased excretion of sodium, potassium, chloride, calcium, magnesium, and water
furosemide adverse effects
Dehydration, hypotension (low BP), electrolyte depletion (especially K+ and Mg), renal impairment, ototoxicity (higher doses, rapid IV administration)
furosemide nursing implications
Monitor urine output, BP, creatinine, K+, Mg (may require electrolyte replacement)
Avoid taking at bedtime
Educate patients on importance of monitoring lab work and BP
Rise slowly when getting up (orthostasis)
Older adults at risk for falls
Related to sulfonamides; watch for cross-sensitivity
Avoid using with other nephrotoxic or ototoxic drugs
If taking digoxin, monitor for toxicity if hypokalemic (low potassium level)
hydrochlorothiazide therapeutic class
Antihypertensive, Drug for edema
hydrochlorothiazide pharmacological class
Thiazide diuretic
hydrochlorothiazide indications
Mild to moderate HTN
hydrochlorothiazide MOA
Affects sodium reabsorption at the distal renal tubule, causing increased excretion of sodium and chloride
hydrochlorothiazide adverse effects
Electrolyte imbalances (dec. K+, Na, Mg), hypotension, vertigo, renal impairment, hyperglycemia in diabetic patients
hydrochlorothiazide nursing implications
Monitor BP, urine output, electrolytes, renal function, administer in morning. Less effective than loop diuretics
lisinopril therapeutic class
drug for HTN, heart failure, MI prevention
lisinopril pharmacologic class
ACE inhibitor
lisinopril indications
HTN, heart failure, acute MI
lisinopril MOA
prevents conversion of angiotensin 1 to angiotensin 2, decreases vasoconstriction and aldosterone secretion
lisinopril adverse effects
orthostatic hypotension, dizziness, headache, persistent dry cough, renal impairment, hyperkalemia, angioedema
lisinopril nursing considerations
discontinue if pregnant (teratogen), patient education (signs of hypotension, angioedema, avoid high sodium and high potassium foods, first dose phenomenon) monitor potassium and renal function (creatinine)
diltiazem therapeutic class
antihypertensive, abtianginal, antiarrhythmic
diltiazem pharmacologic class
calcium channel blocker
diltiazem indications
HTN, angina, tachyarrhythmias
diltiazem MOA
blocks transport of calcium into myocardial and vascular smooth muscle cells
diltiazem contraindications
heart block, shock
diltiazem adverse effects
hypotension, bradycardia, heart failure symptoms, headache, fatigue, n/v, arrhythmias
