The nurse is caring for a client who is admitted with acute dehydration and a serum sodium level of 151mEq/L. The nurse is anticipating the administration of DSW based on which of the following principles?
This fluid is most compatible with antibiotics
This fluid acts as free water to help dilute the sodium.
This fluid contains higher than normal amounts of sodium.
This fluid is used to pull water out of the interstitial space.
The Correct Answer is B
A. DSW (Dextrose in water) is not specifically used for compatibility with antibiotics. It is an intravenous fluid that provides water and glucose, but its use is not based on antibiotic compatibility.
B. DSW (5% dextrose in water) provides free water to the body. In the case of acute dehydration and hypernatremia, the water helps to dilute the high sodium levels in the bloodstream, lowering the sodium concentration.
C. DSW does not contain higher-than-normal amounts of sodium. It contains only a small amount of sodium from the dextrose, and its primary role is to provide free water.
D. DSW is not used to pull water out of the interstitial space. Hypertonic solutions (like 3% saline) are used for that purpose, not DSW.

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.
Correct Answer is ["75"]
Explanation
- Total volume: 1800 mL
- Infusion time: 24 hours
- Calculation: 1800 mL / 24 hours = 75 mL/hour
Therefore, the IV pump should be set to deliver 75 mL/hr.
