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 B
Explanation
A. The erythrocyte sedimentation rate (ESR) is a nonspecific marker of inflammation and is not used to assess the therapeutic effect of epoetin alfa.
B. The hematocrit (Hct) measures the proportion of red blood cells in the blood. Epoetin alfa stimulates the production of red blood cells, leading to an increase in hematocrit levels, indicating a therapeutic effect of the medication.
C. The leukocyte count measures the number of white blood cells in the blood and is not relevant for assessing the therapeutic effect of epoetin alfa.
D. The platelet count measures the number of platelets in the blood and is not relevant for assessing the therapeutic effect of epoetin alfa.
Correct Answer is C
Explanation
A. Respiratory acidosis typically presents with cool, clammy skin due to compensatory peripheral vasoconstriction.

C. Respiratory acidosis can lead to electrolyte imbalances, particularly hyperkalemia, which can manifest as widened QRS complexes on an electrocardiogram (ECG).
D. Respiratory acidosis can lead to hyperkalemia, but hyperactive deep tendon reflexes are not a characteristic finding.
