Carl Shapiro (coronary artery disease) Test Q & A 2025

1. When a patient is experiencing angi- na, the nurse administers nitro- glycerin sublin- gually at what fre- quency? 2. When administer- ing medication to every 5 minutes, maximum 3 doses When a pt is experiencing acute angina, it's recommended that the pt allow 1 sublingual tablet to dissolve under the tongue (or spray nitroglycerin under the tongue) and repeat every 5 min for maximum of 3 doses decreases anxiety decreases pain pt w/ suspected MI, decreases preload the nurse under- stands that mor- phine has which of the following bene- ficial effects? 3. Which of the fol- lowing are cardiac markers assessed decreases afterload Morphine is drug of choice to reduce pain, thereby re- ducing anxiety. it also reduces preload and afterload, decreasing work of heart. pt must be monitored closely for SEs of hypotension and respiratory depression troponin CK-MB in the pt experienc- cardiac enzymes and biomarkers, which include tro- ing angina poten- tial myocardial in- jury? 4. the nurse recog- nizes that ST el- evation on the 12-lead ECG typ- ically indicates which of the fol- lowing? 5. the nurse knows that which fac- ponin, CK, and myoglobin, are used to diagnose an acute MI. of the 3 CK isoenzymes, CK- myocardial bound(MB) is specific to heart muscle. CK-MM is specific to skeletal muscle and is not an indicator of MI. hemoglobinis used to determine amount of O2 in the blood. creati- nine is elevated in renal failure, not in myocardial injury. myocardial injury (causes ST segment and T-wave changes on ECG)
