A nurse is contributing to the plan of care for a client who has hypernatremia. Which of the following interventions should the nurse recommend to include in the plan?

A. Obtain vital signs every 5 min.

Rationale: The client's vital signs indicate hypotension (blood pressure 88/54 mm Hg) and tachycardia (heart rate 104/min). Frequent monitoring of vital signs is essential to assess changes in the client's condition and guide further interventions.

E. Initiate a second peripheral IV.

Rationale: Given the client's low urine output (110 mL over 6 hours) and signs of possible hypovolemia or fluid imbalance, establishing an additional IV line can facilitate the administration of fluids and medications more effectively.

F. Apply oxygen.

Rationale: The client's oxygen saturation is slightly decreased at 96% on room air. Applying supplemental oxygen can help improve oxygenation and alleviate symptoms related to decreased oxygen levels.

Not Recommended Actions:

B. Place the client in high-Fowler's position: This position might not be appropriate for a client with chest pain and potential hypovolemia, as it could exacerbate hypotension.

C. Perform gastric lavage: The output from the nasogastric tube (800 mL sanguineous) does not indicate a need for gastric lavage unless there is a specific reason to suspect gastrointestinal bleeding that requires immediate intervention.

D. Prepare to administer anticoagulants: There is no indication of thromboembolism or need for anticoagulants based on the provided information. The focus should be on addressing hypotension and fluid imbalance.

A. Increase the IV flow rate: This is correct as the client's blood pressure is low, which could indicate hypovolemia or shock. Increasing the IV flow rate can help improve blood volume and blood pressure.
B. Cover the client with a warm blanket: While this can help with hypothermia, it does not address the immediate concern of low blood pressure.
C. Compare the reading to the preoperative value: Comparing to the preoperative value can provide context but does not directly address the current low blood pressure.
D. Reassure the client: Reassuring the client is important but not the first priority. Addressing the physiological issue of low blood pressure should be the initial focus.
