A nurse is assessing a client who is receiving enteral feedings via an NG tube.
The client has developed hyperosmolar dehydration.
Which of the following actions should the nurse take when administering the client's feedings?

Place the client in a quiet environment.

• A. Limiting suctioning the client's airway to 30 seconds at a time can reduce intracranial pressure by minimizing hypoxia and hypercarbia, which can cause cerebral vasodilation and increased cerebral blood volume. However, this intervention alone is not sufficient to prevent increased intracranial pressure, and suctioning should be done only when necessary and with caution. Therefore, this choice is partially correct but not the best answer.
• B. Grouping several nursing activities to be completed at one time can increase intracranial pressure by stimulating the client and causing fluctuations in blood pressure and heart rate.Therefore, this choice is incorrect.
• C. Flexing the client's neck forward can increase intracranial pressure by impeding venous drainage from the brain and increasing cerebral blood volume. Therefore, this choice is incorrect.
• D. Placing the client in a quiet environment can reduce intracranial pressure by minimizing sensory stimulation and promoting relaxation, which can lower blood pressure and heart rate and decrease cerebral metabolic demand. Therefore, this choice is correct and the best answer.

The four findings that require follow-up are B, C, E, and F.

Rationale:

1. Blood pressure: A normal blood pressure for an adolescent is 110/70 mm Hg. The question does not provide the adolescent's blood pressure, so it cannot be determined if it requires followup or not.
2. Capillary refill: A normal capillary refill time is less than 2 seconds. A prolonged capillary refill time indicates impaired blood flow to the extremity, which could be due to vascular injury, compartment syndrome, or shock.
3. Pedal pulse: A normal pedal pulse is +2 or +3. A weak pedal pulse (+1) indicates reduced blood flow to the extremity, which could be due to vascular injury, compartment syndrome, or shock.
4. Heart rate: A normal heart rate for an adolescent is 60 to 100 beats per minute. The question does not provide the adolescent's heart rate, so it cannot be determined if it requires follow-up or not.
5. Skin temperature: A normal skin temperature is warm and dry. A cool skin temperature indicates reduced blood flow to the extremity, which could be due to vascular injury, compartment syndrome, or shock.
6. Pain: A pain level of 10 on a scale of 0 to 10 indicates severe pain that needs to be managed with appropriate analgesics and nonpharmacological interventions.
