A nurse notes that a client's eyes are protruding slightly from their orbits. Which of the following laboratory findings should the nurse expect?
Decreased calcium levels
Decreased somatotropin levels
Increased glucose levels
Increased T4 levels
The Correct Answer is D
Rationale:
A. Decreased calcium levels: Hypocalcemia may cause neuromuscular symptoms such as tetany or tingling but is not associated with exophthalmos (protruding eyes). Calcium imbalance does not typically cause changes in eye appearance.
B. Decreased somatotropin levels: Somatotropin (growth hormone) deficiency may lead to growth delay or reduced muscle mass, but it is not associated with changes in orbital appearance. Protruding eyes are unrelated to growth hormone levels.
C. Increased glucose levels: Elevated glucose is characteristic of diabetes mellitus and may lead to complications like neuropathy or retinopathy, but it does not cause eye protrusion.
D. Increased T4 levels: Elevated thyroxine (T4) is seen in hyperthyroidism, particularly in Graves' disease, which is strongly associated with exophthalmos. The protrusion results from inflammation and edema of orbital tissues, a hallmark of this thyroid disorder.

Correct Answer is A
Explanation
Rationale:
A. Stop the heparin infusion for 1 hr: The client’s aPTT is 105 seconds, which is above the protocol threshold of >95 seconds. Per the titration guidelines, the nurse should hold the infusion for 60 minutes and decrease the rate by 3 units/kg/hr after the hold to reduce bleeding risk.
B. Increase the rate of the infusion by 160 units/hr: Increasing the infusion is appropriate only when aPTT is between 30–49 seconds. Since this client's aPTT is elevated, increasing the rate would further prolong clotting time and increase the risk of hemorrhage.
C. Administer heparin 2,400 unit IV bolus: Bolus doses are prescribed only for low aPTT values (30–49 seconds). Giving a bolus when aPTT is elevated can worsen anticoagulation and significantly increase the potential for bleeding complications.
D. Continue the infusion without change: Continuing the infusion is appropriate when aPTT is within the therapeutic range (50–70 seconds). This client’s aPTT is well above that range, indicating excessive anticoagulation that requires adjustment.
Correct Answer is A
Explanation
Rationale:
A. Increased thirst: Polydipsia, or excessive thirst, is a classic symptom of hyperglycemia. It results from the body's attempt to counteract dehydration caused by osmotic diuresis, which occurs when high glucose levels pull fluid into the urine.
B. Decreased urine output: Hyperglycemia typically causes polyuria (increased urine output), not decreased. High glucose concentrations in the blood lead to osmotic diuresis, resulting in frequent and excessive urination.
C. Moist skin: Hyperglycemia is more often associated with dry skin and mucous membranes due to fluid loss. Moist, clammy skin is more characteristic of hypoglycemia, particularly when it is accompanied by sweating and other adrenergic symptoms.
D. Tremors: Tremors are more commonly associated with hypoglycemia due to increased sympathetic nervous system activity. Hyperglycemia usually develops more gradually and does not typically produce tremors.
