A patient's medication regimen for the treatment of hypertension includes hydrochlorothiazide. Following administration of this medication, the nurse should anticipate what effect?

Correct Answer: B

Rationale: Thiazide diuretics lower BP by reducing circulating blood volume; this results in a short-term increase in urine output. These drugs do not cause bradycardia, agitation, or drowsiness.

Correct Answer: D

Rationale: For a Caucasian male under 55 with no comorbidities, ACE inhibitors (e.g., lisinopril, ramipril) are first-line per guidelines like NICE. Enalapril is an ACE inhibitor but less commonly used as a starting dose compared to lisinopril or ramipril, making it not a typical first-line choice.

Correct Answer: A

Rationale: A heart murmur is typically caused by leaky or improperly functioning valves.

Correct Answer: C

Rationale: Sympathetic stimulation increases the force of cardiac contraction, thereby increasing stroke volume.

Correct Answer: C

Rationale: Venous return depends on factors like skeletal muscle contraction, respiration, and total blood volume but is independent of the speed of blood flow itself.
