ANSWERS 2025/2026.
When atrial flutter occurs, the atrial impulse reenters and depolarizes at 200-300
impulses per minute - False
Calcium channel blockers are equally effective as beta-blockers in reducing anginal
symptoms in stable patients - True
Angina is another term for ________ - Chest pain
Antiplatelet agents prevent platelet aggregation - True
Calcium entry blockers prevent calcium influx into the muscle cells of blood vessel walls
- True
Adrenergic antagonists increase blood pressure by stimulating the heart, and/or
constricting peripheral blood vessels - False
Peripheral antiadrenergics prevent norepinephrine release from peripheral nerve
terminals - True
Shock is a potentially fatal condition in which tissues are poorly perfused and,
consequently, become ischemic - True
Vasopressors constrict blood vessels and improve cardiac function by inhibiting
adrenergic receptors - False
What structure is considered to be the pacemaker of the heart? - Sinoatrial node
Diuretics reduce blood pressure and edema by increasing urine production - True
Loop diuretics are more powerful than thiazides and must be used cautiously to avoid
dehydration - True
Myocardial cells require ________ to function - Oxygen
Beta blockers reduce ischemic burden in unstable angina by: - Decreasing heart rate
and blood pressure
Heparin _________ clotting in the myocardial arteries - Inhibits
