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.

Answer: A. Administer furosemide.

Rationales

A. Administer furosemide.
Furosemide, a loop diuretic, helps reduce fluid overload by promoting urinary excretion of sodium and water. In a client with cirrhosis and ascites, it decreases abdominal distention, eases breathing by reducing pressure on the diaphragm, and prevents complications related to severe fluid accumulation.

B. Weigh the client weekly.
Weekly weights would not provide sufficient monitoring for a client with ascites, since fluid retention can change rapidly within hours or days. Daily weights are necessary to detect subtle increases in fluid status and to evaluate the effectiveness of treatment.

C. Offer the client a high-sodium diet.
A high-sodium diet would worsen fluid retention and ascites, as sodium promotes water retention. Instead, a low-sodium diet is indicated to limit further fluid buildup in the peritoneal cavity.

D. Administer heparin.
Heparin is not a standard intervention for cirrhosis with ascites. Because the diseased liver produces fewer clotting factors, clients are already at risk for bleeding, and anticoagulant therapy would heighten this risk without addressing the underlying problem of fluid accumulation.
