Urinary System Multiple Choice Questions Questions
Question 1 of 5
The alpha blocker with least adverse effect on ejaculatory function is
Correct Answer: B
Rationale: Alfuzosin minimally affects ejaculatory function less selective for alpha-1a receptors in seminal vesicles/prostate, reducing retrograde ejaculation risk. Tamsulosin and silodosin, highly alpha-1a selective, disrupt emission common side effect. Naftopidil (less studied) also impacts ejaculation similar selectivity. Alfuzosin's broader profile distinguishes it, key to preserving sexual function in LUTS treatment, unlike selective blockers' ejaculatory interference.
Question 2 of 5
The targets of angiotensin II are blood vessels and
Correct Answer: B
Rationale: Angiotensin II targets blood vessels (vasoconstriction) and adrenal cortex (aldosterone release), not nerves, medulla (catecholamines), or nephron directly. This specifies RAAS effects, critical for sodium retention, contrasting with other systems.
Question 3 of 5
The outermost covering of the kidney is the
Correct Answer: D
Rationale: The renal capsule (fibrous) encases the kidney, not cortex, medulla (inner), or pelvis (collecting). This distinguishes external anatomy, critical for protection, contrasting with internal regions.
Question 4 of 5
The kidney secretes which is an enzyme hormone that raises blood pressure.
Correct Answer: B
Rationale: Renin, an enzyme from JG cells, initiates RAAS to raise BP, not aldosterone (steroid), angiotensinogen (substrate), or angiotensin II (product). This identifies BP regulator, critical for hypertension, contrasting with downstream factors.
Question 5 of 5
Renal calculi are usually comprised of the following except which one?
Correct Answer: B
Rationale: Renal stones include calcium oxalate, uric acid, and magnesium phosphate not cholesterol (biliary stones). This distinguishes urinary stone composition, critical for treatment, contrasting with lipid-based calculi.
