A nurse is caring for a client who has a sulfa allergy.
Which of the following prescriptions should the nurse clarify with the provider?

Choice A rationale

A changed mental status is a common sign of a urinary tract infection, especially in older adults, due to the effects of the infection on the central nervous system.

Choice B rationale

WBC count 9,000/mm³ is within the normal range of 5,000 to 10,000/mm³ and does not indicate an infection on its own.

Choice C rationale

Diminished reflexes are not typically associated with bladder infections and are not a reliable indicator.

Choice D rationale

A temperature of 37.3°C (99.1°F) is within the normal range and does not necessarily indicate a bladder infection.

Choice A rationale

Performing neurovascular checks every 2 hours ensures that the nurse can quickly identify signs of compromised circulation or nerve function in the affected extremity. This includes monitoring for changes in color, temperature, sensation, and movement, which are critical for preventing complications such as compartment syndrome.

Choice B rationale

Positioning the fractured arm below the level of the client's heart can increase swelling and impair circulation to the area. It is generally recommended to elevate the arm to reduce edema and promote better blood flow.

Choice C rationale

Immobilizing the client's fingers using a hand splint is not necessary unless there are additional injuries to the hand or fingers. The focus should be on the distal radius fracture and maintaining mobility in the fingers to prevent stiffness and promote circulation.

Choice D rationale

Using a hair dryer to blow hot air into the cast can cause skin burns and damage the cast material. Itching under the cast should be managed with safe methods such as blowing cool air or taking antihistamines if necessary.
