What should the nurse suspect when hourly assessment of urine output on a client post-craniotomy exhibits a urine output from a catheter of 1,500 mL for two consecutive hours?
Cushing syndrome.
Adrenal crisis.
Arginine vasopressin deficiency (AVP-D).
Syndrome of inappropriate antidiuretic hormone (SIADH).
The Correct Answer is C
Choice A rationale
Cushing syndrome involves overproduction of cortisol and does not cause rapid urine output.
Choice B rationale
Adrenal crisis does not typically present with excessive urine output and would have other symptoms such as low blood pressure and electrolyte imbalances.
Choice C rationale
Arginine vasopressin deficiency (AVP-D), also known as diabetes insipidus, causes excessive urine output due to the lack of antidiuretic hormone (ADH).
Choice D rationale
Syndrome of inappropriate antidiuretic hormone (SIADH) causes water retention and low urine output, not excessive urine output. .

Correct Answer is B
Explanation
Choice A rationale
A CPP within normal limits ranges from 60 to 80 mm Hg, so a value of 40 mm Hg is not within this range.
Choice B rationale
A CPP of 40 mm Hg is considered low and indicates inadequate cerebral blood flow, which can result in brain ischemia and damage.
Choice C rationale
The reading of 40 mm Hg is considered accurate, as it reflects the current CPP of the client.
Choice D rationale
A CPP of 40 mm Hg is not high but low, indicating compromised cerebral perfusion.
Correct Answer is C
Explanation
Choice A rationale
A pustule is an elevated, round lesion filled with pus, not serum. Pustules are commonly seen in acne or infections.
Choice B rationale
A macule is a flat, discolored area of the skin that is not elevated. Macules do not contain fluid and are often seen in conditions like freckles or flat moles.
Choice C rationale
A vesicle is an elevated, round lesion filled with clear serum. Vesicles can result from conditions such as chickenpox, herpes simplex, or dermatitis.
