1. A patient with hyperthyroidism
reports heat intolerance. What is the
underlying cause?
,A. Decreased metabolic rate
B. Increased catecholamine sensitivity
C. Decreased cardiac output
D. Reduced oxygen consumption
Answer: B
Rationale: Hyperthyroidism increases
beta-adrenergic sensitivity, causing heat
intolerance, tachycardia, and sweating.
2. Which lab value is most indicative of
primary hypothyroidism?
A. Low TSH, low T4
B. High TSH, low T4
C. Low TSH, high T4
D. Normal TSH, low T4
,Answer: B

the thyroid fails, leading to low T4 and
compensatory elevated TSH.
3. A patient with Cushing’s syndrome is
at highest risk for:
A. Hypoglycemia
B. Weight loss
C. Infection
D. Bradycardia
Answer: C
Rationale: Excess cortisol suppresses the
immune system, increasing infection risk.
, 4. Which electrolyte imbalance is
expected in Addison’s disease?
A. Hypernatremia
B. Hypokalemia
C. Hyponatremia
D. Hypercalcemia
Answer: C
Rationale: Aldosterone deficiency leads
to sodium loss and hyponatremia.
5. A priority intervention for diabetic
