A client is admitted with hypovolemia due to severe bleeding. Which IV fluid does the nurse anticipate using to replace fluid losses?

5% dextrose in water (D5W).

5% dextrose in 0.25% sodium chloride (D5 1/4 NS).

0.9% normal saline (0.9% NaCl).

3% sodium chloride (3% NaCl).

Answer and Explanation

The Correct Answer is C

Choice A reason:

5% dextrose in water (D5W) is not typically used for fluid resuscitation in cases of hypovolemia due to severe bleeding. D5W is a hypotonic solution once the dextrose is metabolized, which means it does not remain in the intravascular space and is not effective in expanding blood volume. It is more commonly used for providing free water and calories.

Choice B reason:

5% dextrose in 0.25% sodium chloride (D5 1/4 NS) is also not suitable for fluid resuscitation in hypovolemia due to severe bleeding. This solution is hypotonic and will not adequately expand the intravascular volume. It is generally used for maintenance fluids rather than for resuscitation.

Choice C reason:

0.9% normal saline (0.9% NaCl) is the preferred choice for fluid resuscitation in hypovolemia due to severe bleeding. It is an isotonic solution, meaning it has the same osmolarity as blood and remains in the intravascular space, effectively expanding blood volume. This helps to restore circulating volume and improve tissue perfusion.

Choice D reason:

3% sodium chloride (3% NaCl) is a hypertonic solution and is not typically used for fluid resuscitation in hypovolemia due to severe bleeding. Hypertonic solutions can cause rapid shifts of fluid from the intracellular to the extracellular space, which can lead to complications such as hypernatremia and osmotic demyelination syndrome. It is generally reserved for specific situations such as severe hyponatremia.

Correct Answer is ["25"]

Explanation

The nurse should regulate the IV flow at 25 gtts/min.

Calculation and Answer

Step 1: Determine the total volume to be infused.

Volume = 100 mL

Step 2: Determine the time over which the infusion will occur.

Time = 1 hour = 60 minutes

Step 3: Determine the drip factor.

Drip factor = 15 gtts/mL

Step 4: Calculate the IV flow rate using the formula:

Flow rate (gtts/min) = (Volume (mL) × Drop factor (gtts/mL)) ÷ Time (min)

Step 5: Substitute the values into the formula.

Flow rate (gtts/min) = (100 mL × 15 gtts/mL) ÷ 60 min

Step 6: Perform the multiplication.

100 mL × 15 gtts/mL = 1500 gtts

Step 7: Perform the division.

1500 gtts ÷ 60 min = 25 gtts/min

The nurse should regulate the IV flow at 25 gtts/min.

Correct Answer is ["66.7"]

Explanation

Step 1: Determine the total volume to be administered. Total volume = 1600 mL

Step 2: Determine the total time in hours. Total time = 24 hours

Step 3: Calculate the rate in mL/hr. Rate = Total volume ÷ Total time Rate = 1600 mL ÷ 24 hours Rate = 66.6667 mL/hr

Step 4: Round to the nearest tenth. Rounded rate = 66.7 mL/hr

The nurse should set the IV pump to deliver 66.7 mL/hr.
