Endocrine System Exam Questions
Answers and Rationale

11) C
- Assessment findings in the client who is hypocalcemic include a positive Chvostek's sign, positive Trousseau's sign, hyperactive deep tendon reflexes, circumoral paresthesia, and numbness and tingling of the fingers. A positive Homans' sign would be noted in thrombophlebitis.

12) D
- Trousseau's sign occurs when spasms of the wrist and the hand occur after compression of the upper arm by a blood pressure cuff. Chvostek's sign is present when spasms of the facial muscles occur after a tap over a facial nerve, signifying facial hyperirritability. Homans' sign is the presence of pain in the calf area when the foot is dorsiflexed; this finding indicates thrombophlebitis. The Allen's test is done to assess for adequate circulation to the hand before obtaining arterial blood gases.

13) A
- Clinical manifestations associated with hypothyroidism include bradycardia; obesity; dry, sparse hair; flaky, dry, inelastic skin; and a lowered basal body temperature. The client's ability to sweat also diminishes. Constipation and fecal impaction occur, and the client has an increased susceptibility to infection. Blood pressure may be normal or slightly elevated, and temperature will be normal to subnormal. Exophthalmos and hyperactivity are manifestations of hyperthyroidism.

14) D
- In hypothyroidism, the client's neurological manifestations include decreased deep tendon reflexes, muscle sluggishness, fatigue, slow and deliberate speech, apathy, depression, impaired short-term memory, and lethargy. Options A, B and C are signs of hyperthyroidism.

15) A
Thyroid storm is a potentially fatal acute episode of thyroid overactivity characterized by high fever, severe tachycardia, delirium, dehydration, and extreme irritability. Because it is an emergency, thyroid storm requires heroic interventions for control. The high fever is treated with hypothermic blankets, and dehydration is reversed with intravenous fluids. Options C and D are treatment measures for hypothyroidism.
