A nurse administers desmopressin to a client who has a diagnosis of diabetes insipidus. The nurse recognizes that which of the following laboratory findings indicate a therapeutic effect of the medication?

A. Monitor for postural hypotension: This is unlikely in Cushing’s syndrome, where hypertension (not hypotension) is more common due to excess cortisol and fluid retention.
B. Assess blood glucose level: Hyperglycemia is common in Cushing’s syndrome due to the effects of cortisol on glucose metabolism, so monitoring blood glucose levels is essential.
C. Monitor for an irregular heart rate: While Cushing's syndrome can lead to electrolyte imbalances that may affect heart rhythm, this is not a primary intervention in Cushing's syndrome. Monitoring for hypertension and fluid retention is more critical.
D. Assess for neck vein distention: Elevated cortisol levels can lead to fluid retention and hypertension, contributing to neck vein distention, so this is an important observation.
E. Weigh the client daily: Fluid retention and weight gain are key features of Cushing's syndrome, so daily weight monitoring helps assess fluid status and detect rapid weight gain indicative of worsening symptoms.

A. Moon face is typically associated with Cushing's syndrome, not acromegaly, which is characterized by changes in the hands, feet, and facial features rather than a rounded, moon-shaped face.
B. Enlarged distal extremities (hands and feet) are classic symptoms of acromegaly due to excessive growth hormone production.
C. Hepatomegaly (enlarged liver) is a common finding in acromegaly due to the overproduction of growth hormone, which affects organ size.
D. Coarse facial features (such as a protruding jaw, enlarged nose, and thickened lips) are a hallmark of acromegaly, resulting from the overgrowth of soft tissues.
E. Loss of color discrimination is not typically associated with acromegaly and may be seen in other conditions affecting the optic nerve or eye, but it is not a key symptom of acromegaly.
