A nurse is planning care for a client who is 6 hr. postoperative following a right knee arthroplasty. Which of the following interventions should the nurse include in the client's plan of care?

Choice A Reason:

Muscle spasms of the left leg can be uncomfortable and may require interventions such as muscle relaxants or repositioning of the limb, but they do not pose an immediate threat to the client's limb or life.

Choice B Reason:

One fingerbreadth of space between the cast and the skin is an important measurement to ensure that the cast is not too tight, but it does not represent an immediate threat to the client's circulation.

Choice C Reason:

Diminished pulses on the affected extremity. Diminished pulses on the affected extremity, in this case, the left leg with the long leg cast, is the most critical finding that requires immediate attention. It could indicate compromised blood flow, which is a medical emergency. Compromised blood flow can lead to tissue ischemia and necrosis if not promptly addressed.

Choice D Reason:

Ecchymosis (bruising) on the inner left thigh is concerning but may be related to the cast application or other factors. While it should be assessed and monitored, it is not as urgent as diminished pulses.

Dry, itchy skin is a common concern in older adults, especially during the winter months or in dry environments. Increasing the humidity in the client's environment can help alleviate dryness and itching. Placing a humidifier in the client's room will add moisture to the air and help prevent excessive drying of the skin. It is important to ensure that the humidifier is clean and well-maintained to avoid the growth of bacteria or mould.

Encouraging the client to bathe frequently may further dry out the skin, so it is not recommended. Similarly, applying powder to the skin may exacerbate dryness and should be avoided. Adding moisturizing oil to the bath water may provide temporary relief, but a humidifier will have a more consistent and long-lasting effect on the client's environment.
