A nurse is caring for a client who has diabetes insipidus and is receiving desmopressin by intermittent IV balus. Which of the fediowing manifestations should indicate to the nurse a therapeutic response to the medication?
Decrease in urine output
Increase in serum glucose
Increase in WBC count
Decrease in blood pressure
The Correct Answer is A
A. Decrease in urine output:
This is the correct answer. Desmopressin is a synthetic form of antidiuretic hormone (ADH) that works to reduce urine output in individuals with diabetes insipidus. A decrease in urine output indicates a positive response to the medication.
B. Increase in serum glucose:
Desmopressin does not have a direct effect on serum glucose levels. Its primary action is to increase water reabsorption in the kidneys, reducing urine output.
C. Increase in WBC count:
Desmopressin does not have a direct impact on white blood cell (WBC) count. Its main action is on fluid balance and urine concentration.
D. Decrease in blood pressure:
Desmopressin can cause a mild increase in blood pressure, particularly at higher doses. However, blood pressure changes are not the primary therapeutic effect of desmopressin in the context of diabetes insipidus.

Correct Answer is C
Explanation
A. Orthostatic hypotension:
Orthostatic hypotension is not a common adverse effect of pioglitazone. This condition is more associated with medications that affect blood pressure or volume.
B. Tinnitus:
Tinnitus (ringing in the ears) is not typically associated with pioglitazone. Adverse effects of pioglitazone are more related to its impact on glucose metabolism and other metabolic processes.
C. Fluid retention:
This is the correct answer. Fluid retention is a known adverse effect of pioglitazone. It can lead to edema, weight gain, and, in some cases, exacerbation of heart failure. Monitoring for signs of fluid retention is important during treatment with pioglitazone.
D. Insomnia:
Insomnia is not a common adverse effect of pioglitazone. Adverse effects are more related to metabolic processes, and sleep disturbances are not typically associated with this medication.
Correct Answer is C
Explanation
A. Transdermal: Epoetin alfa is not available for transdermal administration. It's a medication typically administered by injection.
B. Oral: Epoetin alfa is not orally active and is not available in oral form. The oral route is not suitable for this medication due to its large molecular size and degradation in the digestive system.
C. Intravenous (IV): This is the correct route for administering epoetin alfa. It is usually given as an intravenous injection in clinical settings.
D. Inhalation: Epoetin alfa is not formulated for inhalation. It is not administered through the respiratory system but rather through injection, most commonly intravenously.
