Urinary System Test Questions And Answers Questions
Question 1 of 5
ADH administration will not stop diuresis if it is:
Correct Answer: C
Rationale: ADH won't stop diuresis in nephrogenic diabetes insipidus tubules resist (e.g., receptor defect). Lack of ADH responds diabetes insipidus. Excess water dilutes ADH corrects. Combined is treatable ADH works. Resistance distinguishes it, critical for ADH failure, unlike responsive causes.
Question 2 of 5
The main function of the urinary system is to:
Correct Answer: A
Rationale: The urinary system excretes waste (e.g., urea) and balances fluids/electrolytes not enzyme production (digestive), oxygen transport (respiratory), or temperature (skin). This defines its primary role, critical for homeostasis, contrasting with unrelated systems.
Question 3 of 5
The hormone that regulates water balance in the kidneys is:
Correct Answer: B
Rationale: ADH increases water reabsorption in collecting ducts not aldosterone (Na+/K+), insulin (glucose), or oxytocin (labor). This identifies water regulation, key for urine concentration, contrasting with electrolyte or metabolic hormones.
Question 4 of 5
The presence of glucose in urine is called:
Correct Answer: B
Rationale: Glycosuria is glucose in urine not proteinuria (protein), hematuria (blood), or pyuria (pus). This identifies diabetic marker, key for diagnosis, contrasting with other abnormalities.
Question 5 of 5
The structure that controls urine release from the bladder is the:
Correct Answer: B
Rationale: Sphincters (internal involuntary, external voluntary) control release not ureter, loop, or duct (kidney). This defines continence mechanism, key for micturition, contrasting with renal structures.
