Increase alveolar ventilation decreases what?

Correct Answer: D

Rationale: Increased ventilation decreases extracellular COâ‚‚ blows off COâ‚‚, raising pH (e.g., respiratory alkalosis). Intracellular H lowering is secondary pH effect. Intracellular COâ‚‚ shifts less direct. Extracellular H decrease follows COâ‚‚ primary. COâ‚‚ reduction distinguishes it, key to ventilatory pH shift, unlike H or intracellular focus.

Correct Answer: B

Rationale: Nephrons filter blood and form urine not transport (ureters), absorb nutrients (gut), or store waste (bladder). This defines their role, key for renal function, contrasting with downstream or unrelated tasks.

Correct Answer: C

Rationale: The bladder stores urine not kidney (production), ureter (transport), or urethra (exit). This identifies storage organ, key for micturition, contrasting with production/transport roles.

Correct Answer: A

Rationale: Renal failure is impaired filtration not hypertension (cause), diabetes (risk), or stones (obstruction). This defines kidney dysfunction, key for prognosis, contrasting with related conditions.

Correct Answer: A

Rationale: Oliguria is low output (<400 mL/day) not polyuria (excess), anuria (<50 mL), or glycosuria (glucose). This identifies reduced flow, key for renal assessment, contrasting with excess or unrelated terms.
