A nurse is assessing a client who is postoperative following abdominal surgery and has an indwelling urinary catheter that is draining dark yellow urine at 25 mL/hr.

Which of the following interventions should the nurse anticipate?

The correct answer is choice A. A client who has a hip fracture and a new onset of tachypnea.

This client has a high risk of developing a pulmonary embolism, which is a life-threatening condition that requires immediate intervention.

Tachypnea is a sign of respiratory distress and hypoxia, which can indicate a pulmonary embolism.

The nurse should assess this client first and notify the provider.

Choice B is wrong because a client who has diabetes mellitus and an HbA1c of 6.8% is wellcontrolled and does not need urgent attention.

The normal range for HbA1c is 4% to 6%, and the goal for diabetic clients is less than 7%.

Choice C is wrong because a client who has epidural analgesia and weakness in the lower extremities is expected to have some degree of motor impairment due to the medication.

The nurse should monitor the client’s sensation, movement, and pain level, but this is not a priority over choice A. Choice D is wrong because a client who has sinus arrhythmia and is receiving cardiac monitoring is not in immediate danger.

Sinus arrhythmia is a normal variation of heart rhythm that occurs with breathing.

The nurse should observe the client’s vital signs and cardiac rhythm, but this is not a priority over choice A.

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.
