A nurse is reviewing the ABGs of a client who has pneumonia. The nurse should identify which of the following findings is an indication of respiratory acidosis.

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:
Applying clean gloves when removing the old dressing from the catheter site is essential to prevent infection and maintain an aseptic technique during peritoneal dialysis catheter care. Gloves protect both the nurse and the patient from potential contamination.
Choice B rationale:
Cleansing the area by using a circular motion beginning at the catheter site and moving outward is not the correct technique. When caring for a dialysis catheter, the nurse should cleanse the site using an outward, circular motion starting from the insertion site to minimize the risk of contamination.
Choice C rationale:
Using warm water to cleanse the catheter site is not recommended. The peritoneal dialysis catheter site should be cleaned with an appropriate antiseptic solution or disinfectant, as warm water alone may not effectively remove bacteria or prevent infections.
Choice D rationale:
Placing an occlusive dressing over the catheter site after cleaning is not the standard practice for peritoneal dialysis catheter care. Typically, a clean, dry dressing is applied to the catheter site after cleaning to keep it clean and dry, but it should not be occlusive.
