When you're in a formal situation and can't go to bathroom with a full bladder, what will happen?

Correct Answer: B

Rationale: Inhibiting the pudendal nerve (somatic) contracts the external sphincter delays voiding (e.g., voluntary control). Pelvic nerve inhibition stops reflex misdirected. Hypogastric (sympathetic) inhibition relaxes bladder opposite. Parasympathetic inhibition halts contraction partial. Pudendal's role distinguishes it, critical for continence, unlike visceral or system-wide errors.

Correct Answer: B

Rationale: Sympathetic constriction of afferent/efferent arterioles lowers GFR less filtration, more Na reaches macula densa (e.g., reduced reabsorption upstream). GFR increase is opposite vasodilation. More Na in PCT reabsorption needs higher flow false. Filtered Na drops low GFR. Macula densa delivery distinguishes it, key to feedback, unlike GFR or reabsorption errors.

Correct Answer: B

Rationale: Moistening mouth/throat mucosa inhibits thirst signals hydration (e.g., sensory feedback). Stomach/intestinal stretch activates opposite. Both miscombine stretch stimulates. None ignores mucosa false. Mucosal relief distinguishes it, key to thirst cessation, unlike stretch or null options.

Correct Answer: A

Rationale: Rising [H ] lowers pH acidosis (e.g., pH = -log[H ]). pH increase is alkalosis opposite. Increased pH with acidosis contradicts false. Fallen pH with alkalosis reverses incorrect. Acidosis link distinguishes it, key to pH definition, unlike reversed or mixed errors.

Correct Answer: D

Rationale: Compensated metabolic alkalosis shows high PCO₂ (hypoventilation), high HCO₃⁻ (primary), high pH lungs retain CO₂ to offset (e.g., vomiting). Low PCO₂ is uncompensated acute. Low HCO₃⁻/pH is acidosis opposite. High PCO₂/low pH is respiratory acidosis unrelated. Compensation distinguishes it, key to acid-base balance, unlike uncompensated or opposite states.
