NURS 504 Exam 2 Questions and
Answers
Beta blockers ✅"olols"
Metoprolol
Propranolol
Carvedilol

Pharmacodynamics of beta blockers ✅-prevent beta-adrenergic receptors from being
stimulated
-decrease the oxygen demands of heart and decrease angina
-causes blockade in myocardium/electrical conduction
Decrease hr
Vasodilator
-reduces release of renin

Overall role of beta blocker ✅slow hr by suppressing the sa node which slows the
speed of conduction through the av node
-decreases the force of contraction
-decrease bp
-reduce contractility

How do beta blockers work ✅block epinephrine from binding to the beta receptors
which causes the heart to beat slower and reduces blood pressure, lowering bp

Beta blocker prototype drug ✅metoprolol (lopressor)

Side effects of beta blockers ✅bradycardia
Bronchoconstriction
Decreased cardiac output
Av block
Hypotension

Class i ✅lidocaine

Nursing interventions beta blockers ✅-do not abruptly stop medication
-monitor blood pressure, pulmonary wedge pressure, and cardiac rhythm and
conduction (check ekgs)

Metoprolol ✅treatment of hypertension, angina, controlled congestive heart failure
-do not abruptly stop medication
-goal: decrease workload on heart and its oxygen need

, Goal of anti-hypertension medications ✅affect/change one or more mechanisms that
affect peripheral resistances

Starting medication for high bp ✅diuretic

Loop diuretics ✅furosemide (lasix)
Bumetanide
Torsemide
-always have ide

Furosemide (lasix) ✅loop diuretic
Treats peripheral and pulmonary edema and hypertension by inhibiting the reabsorption
of sodium, chloride, and water in the ascending loop of henle

Pharmacodynamic of loop diuretics ✅block reabsorption of sodium/chloride and
prevent reabsorption of water in loop of henle
-decrease blood volume
-excretion of water and sodium

Side effects of loops diuretic ✅ototoxicity/tinnitus (hearing problems), dehydration,
electrolyte imbalance, hypotension, hypokalemia

Hypokalemia ✅deficient potassium in the blood (normal 3.5-5)
-issues are generally cardiac and dysrhythmia related

Thiazide diuretics ✅hydrochlorothiazide (hctz)
-always have thiazide in them

Pharmacodynamics of thiazide diuretic ✅block reabsorption of sodium/chloride and
prevent reabsorption of water in distal convoluted tubule

Side effects of thiazide diuretic ✅dehydration
Hypokalemia
Hypotension
Hyperglycemia

Potassium sparing diuretics ✅spironolactone (aldactone)

Spironolactone ✅potassium sparing diuretic
Manage edema and hypertension by inhibiting transport of sodium in distal convoluted
tubules, decreases sodium and water reabsorption but increases potassium retention

Pharmacodynamics potassium sparing diuretics ✅block action of aldosterone which
results in potassium retention and excretion of na and h2o
