A nurse is planning to teach a client about taking prednisone.

Which of the following instructions should the nurse include?

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.

Hypertonicity is a sign of increased muscle tone and stiffness, which can indicate that the newborn is experiencing withdrawal from methadone exposure in utero. Methadone is an opioid medication that can cross the placenta and cause neonatal abstinence syndrome (NAS) in the newborn.

Choice A is wrong because it is a normal finding in newborns.

Acrocyanosis is a bluish discoloration of the hands and feet due to immature peripheral circulation. It usually resolves within the first 24 to 48 hours of life.

Choice B is wrong because it is not a typical sign of withdrawal.

Bradycardia is a slow heart rate, usually less than 100 beats per minute in newborns. It can be caused by hypoxia, hypothermia, hypoglycemia, or vagal stimulation.

Choice C is wrong because it is a sign of increased intracranial pressure, not withdrawal. Bulging fontanels can be caused by meningitis, hydrocephalus, or hemorrhage.

Normal ranges for newborn vital signs are as follows:

• Heart rate: 120 to 160 beats per minute
• Respiratory rate: 30 to 60 breaths per minute
• Temperature: 36.5 to 37.5°C (97.7 to 99.5°F)
• Blood pressure: 60 to 80 mm Hg systolic and 40 to 50 mm Hg diastolic
