A nurse is teaching a client who has a new prescription for colesevelam powder for oral suspension. The nurse should include which of the following instructions?

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.

Dispose of the client's feces and urine in a special container.

Choice A rationale:

This is the correct choice. Brachytherapy involves the placement of a radiation source in or near the tumor. To minimize radiation exposure to others, the client's bodily fluids (feces and urine) should be considered radioactive and disposed of properly in a designated container.

Choice B rationale:

While limiting the time of visitors can be a good measure to reduce radiation exposure, it is not the priority intervention. The primary concern is proper handling and disposal of radioactive bodily fluids.

Choice C rationale:

Keeping the client's linens in the room until after removal of the radiation source is not the correct choice. Radioactive linens should be handled and laundered separately, following appropriate safety protocols.

Choice D rationale:

Providing one dosimeter badge for staff to share while caring for the client is not adequate. Each staff member involved in direct care should have their dosimeter badge to monitor their individual radiation exposure levels.
