A nurse is caring for a client who exhibits dehydration-induced confusion. Which intervention should the nurse implement first?

Measure intake and output every 4 hours.

Apply oxygen by mask or nasal cannula.

Increase the IV flow rate to 250 mL/hr.

Place the client in a high-Fowler's position.

Answer and Explanation

The Correct Answer is C

A. Measure intake and output every 4 hours: While monitoring intake and output is important, it is not the first priority in this case. The client is exhibiting confusion due to dehydration, and immediate action is needed to correct the fluid deficit.

B. Apply oxygen by mask or nasal cannula: While oxygen may be necessary if the client shows signs of hypoxia, dehydration-induced confusion is primarily related to fluid imbalance rather than oxygenation issues. Administering fluids is the immediate priority.

C. Increase the IV flow rate to 250 mL/hr: Increasing the IV flow rate to rapidly administer fluids is the most immediate intervention to correct dehydration. Restoring fluid volume will help to resolve the confusion and address the underlying issue of dehydration.

D. Place the client in a high-Fowler's position: This position is typically used to assist with breathing or to improve respiratory function, but it does not address dehydration. Fluid resuscitation should be the first action to address confusion related to dehydration.

Correct Answer is ["300"]

Explanation

Calculation:

Total volume of the medication solution to be infused = 300 mL.

Infusion time = 60 minutes.

Convert the infusion time from minutes to hours.

Infusion time in hours = 60 minutes / 60 minutes/hour

= 1 hour.

Calculate the infusion rate in milliliters per hour (mL/hr).

Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)

= 300 mL / 1 hour

= 300 mL/hour.

A. 0.225% sodium chloride (1/4 NS) B. 0.45% sodium chloride (1/2 NS) C. 0.9% sodium chloride (NS) D. 3% sodium chloride (3% NaCl)

Correct Answer is C

Explanation

A. 0.225% sodium chloride (1/4 NS): This hypotonic solution can shift fluids into cells but is not ideal for isotonic therapy. It may cause fluid imbalance and not restore extracellular fluid balance effectively in vomiting and diarrhea.

B. 0.45% sodium chloride (1/2 NS): This is another hypotonic solution that may cause fluid shifts into the cells. It is not isotonic, making it less appropriate for fluid replacement in this case.

C. 0.9% sodium chloride (NS): Normal saline is an isotonic solution that closely matches the osmolality of body fluids. It is the best choice to replace extracellular fluid lost from vomiting and diarrhea.

D. 3% sodium chloride (3% NaCl): This hypertonic solution is used for severe hyponatremia and shifts fluids out of cells. It is inappropriate for fluid replacement in vomiting and diarrhea, as it could lead to fluid overload.
