A nurse is caring for a client who has developed Cushing syndrome due to long-term corticosteroid therapy to treat multiple sclerosis. The nurse understands that Cushing syndrome puts the client at increased risk for which complication?
Ataxic dysarthria
Hypotension
Hyperkalemia
Bone fracture
The Correct Answer is D
A. Ataxic dysarthria: This is not a common complication associated with Cushing syndrome. It is more related to neurological disorders affecting speech and coordination.
B. Hypotension: Cushing syndrome typically causes hypertension rather than hypotension due to fluid retention and increased vascular resistance.
C. Hyperkalemia: Cushing syndrome is associated with hypokalemia rather than hyperkalemia due to the effects of excess cortisol on potassium levels.
D. Bone fracture: Cushing syndrome increases the risk of osteoporosis and bone fractures due to prolonged exposure to high levels of cortisol, which affects bone density and strength.

Correct Answer is A
Explanation
A. B-type natriuretic peptide (BNP): BNP levels are elevated in heart failure due to increased pressure and stretch in the heart's chambers. It is a key marker used to diagnose and assess the severity of heart failure.
B. Troponin I: This marker is used to diagnose myocardial infarction (heart attack) rather than heart failure. Elevated troponin levels indicate damage to the heart muscle.
C. Blood urea nitrogen (BUN): BUN levels can be elevated in heart failure due to decreased renal perfusion, but it is not as specific for diagnosing heart failure as BNP.
D. Platelet levels: Platelet levels are not directly related to the diagnosis of heart failure. They are more relevant for assessing clotting disorders and other conditions.
Correct Answer is ["75"]
Explanation
Step 1: Determine the total infusion time in hours
• There are 24 hours in a day.
Step 2: Calculate the infusion rate
• Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
• Infusion rate = 1800 mL / 24 hr = 75 mL/hr
Therefore, the nurse should set the IV pump to deliver 75 mL/hr.
