A patient with antidiuretic hormone deficiency is receiving desmopressin (DDAVP). The nurse will teach this patient to:
a. avoid grapefruit juice.
b. increase sodium intake.
c. monitor blood pressure.
d. reduce fluid intake.
ANS: D
Patients taking desmopressin should be taught to reduce fluid intake to avoid fluid overload, because this drug prevents continued fluid loss. Desmopressin metabolism is not affected by grapefruit juice. Increasing the sodium intake would only cause increased fluid retention. Desmopressin is a weak pressor agent and does not adversely affect hemodynamics, so monitoring blood pressure is not necessary.
