Correct Answer is D

Explanation

A. A client with heart failure and crackles in the lungs is more likely to have fluid volume excess rather than deficit.
B. A client with renal failure and pitting edema is typically at risk for fluid retention and overload, not deficit.
C. Being NPO for 4 hours is unlikely to cause significant fluid volume deficit, as this is a short period without oral intake.
D. A client with Crohn's disease experiencing diarrhea is losing significant fluids and electrolytes, placing them at high risk for fluid volume deficit. Diarrhea is a common cause of dehydration and requires close monitoring.

Correct Answer is ["125"]

Explanation

Determine the infusion time: The total dose is 40 mEq, and it's being infused at a rate of 10 mEq/hr.
Therefore, the total infusion time is 40 mEq / 10 mEq/hr = 4 hours.
Calculate the infusion rate in mL/hr: The total volume is 500 mL, and the infusion time is 4 hours.
So, the infusion rate is 500 mL / 4 hours = 125 mL/hr.
