Correct Answer: B

Rationale: The correct answer is to change the TPN tubing every 24 hours. This action helps reduce the risk of infection because the high glucose content of TPN promotes bacterial growth. Choice A is incorrect as changing the tubing every 48 hours would not provide adequate infection prevention. Option C, monitoring urine output, is important for assessing renal function but is not directly related to preventing TPN-related infections. Option D, monitoring weight, is essential for assessing nutritional status but does not directly address infection prevention in TPN administration.

Correct Answer: D

Rationale: The correct answer is to infuse the blood within 4 hours. This is crucial to prevent bacterial contamination and hemolysis during blood transfusions. Monitoring the client's blood glucose level every hour (Choice A) is not directly related to packed RBC transfusions. Administering the blood using a microdrip set (Choice B) may be appropriate for specific medications but is not a requirement for packed RBC transfusions. Assessing the client's vital signs every 2 hours (Choice C) is important for monitoring the client's overall condition but is not as time-sensitive as ensuring the timely infusion of packed RBCs.

Correct Answer: D

Rationale: The correct answer is D. A high erythrocyte sedimentation rate (ESR) of 75 mm/hr indicates inflammation, which is common in rheumatoid arthritis. Elevated ESR levels are often seen in inflammatory conditions like rheumatoid arthritis. Options A, B, and C are within the normal range and are not typically indicative of active inflammation associated with rheumatoid arthritis. Therefore, the nurse should report the elevated ESR level to the provider for further evaluation and management.

Correct Answer: D

Rationale: Clear breath sounds are an essential indicator of effective pneumonia treatment as they suggest resolution of the lung infection. A normal respiratory rate (A) indicates adequate breathing but does not directly reflect the effectiveness of pneumonia treatment. An elevated white blood cell count (B) is a sign of infection and may not decrease immediately with treatment. While maintaining an SpO2 of 95% (C) is crucial for oxygenation, it may not directly indicate the effectiveness of pneumonia treatment.

Correct Answer: B

Rationale: The correct answer is B. Client-reported improvement in anxiety is an indication of effective treatment for pulmonary embolism. Choice A is incorrect as increased density in all lung fields on a chest x-ray may indicate complications or lack of improvement. Choice C is incorrect as diminished breath sounds auscultated unilaterally may suggest a localized lung issue and not necessarily reflect the effectiveness of treatment for a pulmonary embolism. Choice D is incorrect as the ABG results provided do not specifically indicate the effectiveness of treatment for a pulmonary embolism.
