A nurse is teaching a prenatal class about infection prevention at a community center.

Which of the following statements by a client indicates an understanding of the teaching

The correct answer is choice C. Perform the procedure prior to meals.

This is because postural drainage involves positioning the child in different ways to help drain the mucus from the lungs.

If the child has a full stomach, this can cause nausea, vomiting, or aspiration. Therefore, the nurse should perform the procedure before meals or at least 1 hour after meals.

Choice A is wrong because the nurse should not hold the hand flat to perform percussions on the child.

Percussions are rhythmic clapping on the chest wall to loosen the mucus. The nurse should use a cupped hand to create a small air pocket that enhances the vibrations and prevents bruising.

Choice B is wrong because the nurse should not perform the procedure twice a day. The recommended frequency of postural drainage is 3 to 4 times a day, or more if needed, depending on the child’s condition and tolerance.

Choice D is wrong because the nurse should not administer a bronchodilator after the procedure.

A bronchodilator is a medication that relaxes and widens the airways, making it easier to breathe. The nurse should administer a bronchodilator before the procedure to enhance the effectiveness of postural drainage.

The correct answer is choice B. Applying an orthotic to the client’s foot.

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.
