A nurse is teaching a client who has a new prescription for lovastatin. Which of the following diagnostic tests should the nurse instruct the client to complete before starting the medication?

Answer: A

Rationale:

A) Place the client in a room with negative airflow: Disseminated herpes zoster (shingles) requires airborne precautions because the virus can become aerosolized. A room with negative airflow helps prevent the spread of the virus to other areas, protecting healthcare workers and other patients from infection.

B) Remove isolation gown after leaving the client's room: Isolation gowns should be removed before leaving the client's room to prevent the spread of contaminants to other areas. This intervention is important for infection control but is not specific to the requirement for negative airflow in cases of disseminated herpes zoster.

C) Apply ketoconazole to the lesions three times per day: Ketoconazole is an antifungal medication and is not used for treating herpes zoster, which is caused by a viral infection. Antiviral medications, such as acyclovir, are appropriate for treating herpes zoster lesions.

D) Provide the client with eye protection for ultraviolet B light therapy: Eye protection is necessary during UVB light therapy to protect the eyes, but UVB light therapy is not a standard treatment for disseminated herpes zoster. The priority intervention is to prevent the spread of the infection by using a negative airflow room.

Choice A rationale:
Is appropriate to assess postoperative urinary function after transurethral resection of the prostate (TURP). It helps monitor the return of normal bladder function.
Choice B rationale:
Is not necessary and could potentially cause discomfort and increased risk of tube dislodgment. Securing the tube properly to the bed or clothing is a more appropriate method.
Choice C rationale:
Is essential to assess urinary function, and fluid balance, and identify any potential complications such as urinary retention or excessive bleeding.
Choice D rationale:
Helps alleviate discomfort and prevent spasms after TURP. Bladder spasms can be common after the procedure, and antispasmodics can aid in managing them.
Choice E rationale:
Is necessary to keep the catheter patent and prevent clot formation in the urinary tract. It helps maintain proper drainage and prevents complications.
