Correct Answer is C

Explanation

Rationale:
A. Pneumonia typically causes respiratory acidosis due to impaired gas exchange and CO₂ retention.
B. Brain injuries can affect respiratory patterns, but they are not the most common or direct cause of respiratory alkalosis.
C. Anxiety often leads to hyperventilation, which causes excessive loss of CO₂, resulting in respiratory alkalosis.
D. Emphysema is associated with CO₂ retention, leading to respiratory acidosis, not alkalosis.

Correct Answer is ["167"]

Explanation

Rationale:

Step 1: Identify what is given
Total IV fluid volume: 1000 mL
Total infusion time: 6 hours

Step 2: Use the formula for flow rate
Flow rate (mL/hr) = Total volume (mL) ÷ Time (hr)

Step 3: Substitute the values
Flow rate = 1000 mL ÷ 6 hr = 166.67 mL/hr

Step 4: Round to the nearest whole number
166.67 mL/hr ≈ 167 mL/hr

Final Answer: The nurse should set the IV flow rate to 167 mL/hr.
