NSG 318 EXAM 3 QUESTIONS AND
CORRECT ANSWERS
What is the action of Digoxin ✅inhibits sodium-potassium ATPase, promoting
increased force of cardiac contraction, cardiac out, and tissue perfusion; decreases
ventricular rate
What effects on the heart muscle does Digoxin influence? ✅increases myocardial
contractility; decreases HR; decreases conduction and increases cardiac output
Digoxin therapeutic effects/ uses ✅treats heart failure and atrial fibrillation
Therapeutic serum level for Digoxin ✅0.5-1 ng/mL
Important nursing implication the nurse should consider before administering Digoxin?
✅DO NOT administer if under 60 bpm
(Assess BP and HR before administration)
A patient is experiencing an overdose of Digoxin. What is the most appropriate nursing
intervention? ✅administer Digoxin Immune Fab
What is angina? ✅acute cardiac pain caused by inadequate blood flow to the
myocardium
-decreased blood flow= chest pain
What is the action of Nitroglycerin? ✅decreases myocardial demand for oxygen
What are the therapeutic effects/ uses of Nitroglycerin? ✅controls angina
What is the action of Atenolol? ✅selectively blocks beta 1 receptor sites; decreases
sympathetic outflow to the periphery; suppresses renin-angiotensin-aldosterone system
Which drugs are used to treat acute MI? ✅Atenolol, Metoprolol and Nitroglycerin
What is the action of Diltiazem? ✅inhibits the transport of calcium to the myocardial
cells
which drugs contain the suffix -olol ✅beta blockers
What is Diltiazem used for? ✅relaxes both coronary and peripheral blood vessels,
bringing more oxygen to the myocardium and reducing cardiac workload
, -used for HTN and atrial dysthymias
What is the action of Thiazide diuretic? ✅promotes sodium, chloride and water
excretion
-decreases preload and cardiac output, edema
-acts on arterioles and cause vasodilation which decreases BP
What two diuretics act on the renal distal tubules? ✅Thiazide and Spironlactone
What is the action of Metropolol? ✅promotes BP reduction by beta 1 blocking effects
What is the action of Prazosin Hydrochloride? ✅dilates peripheral blood vessel by
blocking alpha adrenergic receptors
What is the action of Lisinopril? ✅inhibit formation of angiotensin II; blocks the release
of aldosterone
what does aldosterone do ✅Increases reabsorption of sodium and increases secretion
of potassium
What is the action of Valsartan? ✅potent vasodilator that inhibits binding of
angiotensin II
ACE inhibitor ✅Lisinopril
What is the action of Heparin ✅inhibits thrombin, which prevents conversion of
fibrogen to fibrin
If a patient is experiencing Heparin overdose. What is the most appropriate nursing
intervention? ✅administering Protamine Sulfate
What is the action of Warfarin (Coumadin)? ✅depresses hepatic synthesis of vitamin K
clotting factors
the patient is experiencing a warfarin overdose. what is the most appropriate nursing
intervention? ✅administering vitamin K
What is the action of Clopidrogel? ✅inhibits platelet aggregation and prevents ADP
(adenosine diphosphate) from binding with the ADP platelet receptors
What is the action of Alteplase (tPA)? ✅promote conversion of plasminogen to plasmin
(an enzyme that digests fibrin matrix of clots)
-initiates fibrinolysis
