ITS REVIEWED 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?
