Multiple Choice Questions On Urinary System Questions
Question 1 of 5
Glomerular(Bowman's)capsule double walled cup lined by
Correct Answer: A
Rationale: Bowman's capsule is lined by simple squamous epithelium, not columnar, cuboidal, or stratified. This identifies capsule lining, vital for filtration, contrasting with thicker epithelia.
Question 2 of 5
An organ or structure that is not a component of the urinary system is the:
Correct Answer: D
Rationale: Adrenal gland (endocrine) isn't urinary, unlike urethra, bladder, ureter. This excludes non-urinary organs, vital for system definition, contrasting with excretory components.
Question 3 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 4 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 5 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.
