A nurse is caring for a school-age child who is 2 hr postoperative following cardiac catheterization.

The nurse observes blood on the child’s dressing.

Which of the following actions should the nurse take?

Hct stands for hematocrit, which is the percentage of red blood cells (RBCs) in the blood. A client who received 2 units of packed RBCs should have an increased Hct because they have more RBCs in their blood volume.

The normal range for Hct is 38% to 50% for males and 36% to 44% for females.

Choice B is wrong because decreased Hgb means decreased hemoglobin, which is the protein that carries oxygen in the RBCs.

A client who received 2 units of packed RBCs should have an increased Hgb because they have more hemoglobin in their blood. The normal range for Hgb is 13.5 to 17.5 g/dL for males and 12 to 15.5 g/dL for females.

Choice C is wrong because increased platelets means increased thrombocytes, which are the cells that help with blood clotting.

A client who received 2 units of packed RBCs should not have an increased platelet count because they did not receive platelets in the transfusion. The normal range for platelets is 150,000 to 400,000/mm^3.

Choice D is wrong because decreased WBC count means decreased leukocytes, which are the cells that fight infection and inflammation.

A client who received 2 units of packed RBCs should not have a decreased WBC count because they did not receive WBCs in the transfusion. The normal range for WBC count is 4,500 to 11,000/mm^3.

An orthotic is a device that supports or corrects the function of a body part. In this case, an orthotic can help prevent foot drop, which is a common contracture deformity in immobile patients. Foot drop occurs when the muscles that lift the foot become weak or paralyzed, causing the foot to hang down at the ankle. An orthotic can keep the foot in a neutral position and prevent shortening of the calf muscles and Achilles tendon.

Choice A is wrong because a trochanter wedge is used to prevent external rotation of the hip, not contracture. A trochanter wedge is a triangular-shaped pillow that is placed between the legs to keep them parallel and aligned.

Choice C is wrong because a towel roll under the neck is used to maintain proper cervical alignment, not contracture. A towel roll can prevent hyperextension of the neck and support the natural curve of the spine.

Choice D is wrong because a pillow under the knees can actually cause contracture of the knee joint by keeping it in a flexed position. A pillow under the knees can also reduce blood flow to the lower extremities and increase the risk of deep vein thrombosis.

Contracture is a permanent tightening of the muscles, tendons, skin, and surrounding tissues that causes the joints to shorten and stiffen.

Contracture can limit the range of motion and function of the affected body part. Contracture can be caused by inactivity, scarring, or diseases that affect the muscles or nerves. Prevention of contractures requires early diagnosis and initiation of physical medicine approaches such as passive range of motion exercises and splinting before contractures are present or while contractures are mild.
