A nurse is caring for a client who is postoperative and is on bed rest. Which of the following actions should the nurse take to decrease the client's risk of developing a pressure injury?

A. Use trochanter rolls beside the client's legs:

Trochanter rolls are positioning devices placed alongside the thighs to prevent external rotation of the hips when a client is lying supine. This helps maintain proper alignment and prevents hip contractures, especially in clients who are immobile.

B. Logroll the client every 4 hr:

Logrolling is a technique used to turn a client with spinal precautions, such as after spinal surgery or injury. It involves turning the entire body as a unit to avoid twisting the spine. However, in a general plan of care for an immobile client, logrolling every 4 hours may not be necessary unless there are specific medical indications.

C. Place the client's arms at their side when turning them:

Placing the client's arms at their side may not be the most optimal positioning during turns, as it can contribute to joint contractures. The nurse should consider positioning the arms in a manner that maintains joint flexibility and prevents contractures.

D. Cross the client's ankles when lying supine:

Crossing the client's ankles when lying supine is not a recommended practice. It can lead to pressure on the lateral aspect of the knees and ankles, potentially causing discomfort and impairing circulation. It is important to maintain proper alignment and support for the client's lower extremities.

A. Use an 18-gauge, 1-inch needle to administer the medication.An 18-gauge needle is too large for subcutaneous heparin injections, which require a smaller, finer needle, typically 25- to 27-gauge and ⅜- to ⅝-inch in length. The smaller gauge reduces discomfort and is appropriate for subcutaneous tissue.

B. Inject 5.1 cm (2 in) away from the umbilicus.Heparin injections should be given at least 2 inches from the umbilicus to avoid areas with dense blood vessels, which decreases the risk of hematoma formation and improves medication absorption.

C. Expel air bubble before injecting medication.For prefilled heparin syringes, the small air bubble should not be expelled, as it helps ensure the full dose is administered and can reduce bruising by sealing the medication in the tissue.

D. Massage the injection site after withdrawing the needle.Massaging the site after a heparin injection is not recommended as it increases the risk of bruising and tissue irritation. Instead, gentle pressure may be applied briefly if there is bleeding at the site.
