Question 1 of 5
Choose the selective blocker of beta-1 adrenoreceptors:
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
All these drug groups useful in angina both decrease myocardial oxygen requirement (by decreasing the determinations of oxygen demand) and increase myocardial oxygen delivery (by reversing coronary arterial spasm), EXCEPT:
Correct Answer: C
Rationale: Nitrates and calcium channel blockers reduce oxygen demand (via preload/afterload reduction) and increase oxygen delivery (via vasodilation/spasm relief). Beta-blockers reduce oxygen demand (via decreased heart rate and contractility) but do not reverse coronary spasm. Potassium channel openers like Minoxidil are vasodilators but are not primarily used in angina.
Question 3 of 5
Main clinical use of calcium channel blockers is:
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Pick out the drug which increases cardiac output:
Correct Answer: A
Rationale: Noradrenalin (norepinephrine) increases cardiac output via beta-1 adrenergic stimulation (inotropic and chronotropic effects) alongside its alpha-mediated vasoconstriction. Methyldopa lowers blood pressure, Phenylephrine is a pure vasoconstrictor, and Angiotensinamide primarily raises pressure via vasoconstriction.
Question 5 of 5
Indicate the group of drugs influencing the cerebral flow:
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
