A nurse is caring for a client who has diabetes insipidus and is receiving vasopressin. The nurse should identify which of the following findings as an indication that the medication is effective?
A decrease in blood pressure
A decrease in blood sugar
A decrease in urine output
A decrease in specific gravity
The Correct Answer is C
A. Vasopressin does not typically affect blood pressure significantly.
B. Vasopressin is not used to lower blood sugar levels; it is primarily used for water retention.
C. Vasopressin, also known as antidiuretic hormone (ADH), acts on the kidneys to decrease urine output, making this the expected outcome of therapy.
D. Specific gravity of urine may increase with vasopressin therapy due to decreased urine output, rather than decrease.

Correct Answer is D
Explanation
A. In primary hypothyroidism, the thyroid gland fails to produce sufficient thyroid hormone.
Consequently, free T4 levels are typically decreased.
B. Although serum T3 levels may also decrease in primary hypothyroidism due to impaired thyroid function, TSH is the primary marker used for diagnosis and monitoring.
C. Similarly, serum T4 levels may decrease in primary hypothyroidism due to decreased synthesis by the thyroid gland.
D. In primary hypothyroidism, the anterior pituitary gland releases more TSH to stimulate the thyroid gland to produce thyroid hormones. Therefore, elevated TSH levels are characteristic of primary hypothyroidism.
Correct Answer is B
Explanation
A. Administering corticosteroids is crucial during an Addisonian crisis but typically involves intravenous corticosteroids (not oral) during the crisis to quickly restore hormone levels. Oral corticosteroids are part of regular maintenance therapy but not an immediate intervention in the crisis.
B. Weighing the client daily is important to monitor for potential fluid loss, dehydration, or weight changes related to Addison's disease and Addisonian crisis. Clients with Addison’s disease may experience fluid and electrolyte imbalances, so daily weight tracking helps detect early signs of fluid shifts, which are critical in crisis prevention and management.
C. A low-carbohydrate diet is not recommended for clients with Addison’s disease, as they may need a balanced diet with sufficient carbohydrates to prevent hypoglycemia.
D. Fluid intake should not be restricted; rather, maintaining adequate hydration is vital. Clients in Addisonian crisis are often at risk for dehydration due to fluid losses and low aldosterone levels, making fluid replacement essential.
