Multiple Choice Questions On Urinary System Questions
Question 1 of 5
Glomerular filtration rate (GFR) is
Correct Answer: A
Rationale: GFR is typically 125 mL/min, not 120, 130, or all. This standardizes filtration rate, vital for renal function, contrasting with approximations.
Question 2 of 5
Which of the following is the correct sequence in which urine flows through the kidney toward the urinary bladder?
Correct Answer: B
Rationale: Urine flows: papillary duct → minor calyx → major calyx → renal pelvis → ureter, not other sequences. This orders urine path, key for drainage, contrasting with misordered flows.
Question 3 of 5
The location of the kidneys in relationship to the peritoneal lining of the abdominal cavity is referred to as
Correct Answer: A
Rationale: Kidneys are retroperitoneal (behind peritoneum), not retroabdominal, posterior (general), or dorsal (back). This positions kidneys, key for surgery, contrasting with vague terms.
Question 4 of 5
In which of the following scenarios is administration of calcium unwise with hyperkalemia?
Correct Answer: A
Rationale: Rhabdomyolysis with hyperkalemia risks hypercalcemia muscle breakdown releases calcium, making IV calcium unwise (e.g., worsens arrhythmias). Nephrotoxic ATN (e.g., drugs) and ischemic ATN (e.g., shock) need calcium to stabilize membranes safe. Glomerulonephritis rarely alters calcium calcium helps. Rhabdomyolysis's calcium surge distinguishes it, key to avoiding iatrogenic harm, unlike ATN or glomerular scenarios where calcium corrects potassium effects.
Question 5 of 5
Which is not a recommended regimen for treatment of UTI in the non pregnant woman?
Correct Answer: D
Rationale: Nitrofurantoin 50 mg QID for 5 days isn't standard dose is low (typically 100 mg), and 3-day courses suffice for uncomplicated UTI, not recommended. Trimethoprim 300 mg daily, Augmentin duo BD, and cephalexin 500 mg BD for 5 days align effective options. Nitrofurantoin's dosing/duration distinguishes it, key to guideline adherence, unlike appropriate regimens.
