Correct Answer: C

Rationale: A temperature of 99°F (37.2°
C) in a postoperative client requires immediate intervention as it may indicate the presence of infection. Elevated temperature post-surgery can be a sign of surgical site infection or systemic infection, which can lead to serious complications if not addressed promptly. Monitoring and managing a fever in a postoperative client is crucial to prevent further complications. The other findings, such as a heart rate of 90 beats per minute, oxygen saturation of 92%, and pain at the surgical site, are common postoperative assessments that may not necessarily require immediate intervention unless they are significantly out of normal range or causing severe distress to the client.

Correct Answer: A

Rationale: The correct answer is A. A hemoglobin level of 12 g/dL is an indicator of effective erythropoietin therapy as it shows an increase in red blood cell production. Reticulocyte count (choice

C) and serum ferritin level (choice
D) are not specific indicators of the effectiveness of erythropoietin therapy for chronic kidney disease.

Rationale: Offering free cancer screenings is the most likely activity to increase participation in the health fair. Providing direct services such as screenings not only attracts participants but also promotes early detection, which is crucial in cancer prevention.

Correct Answer: D

Rationale: The correct first action for a client receiving TPN with an elevated blood glucose level is to check the TPN infusion rate. Elevated blood glucose levels in clients receiving TPN can be due to incorrect infusion rates leading to increased glucose delivery. By checking the TPN infusion rate, the nurse can verify if the rate is appropriate and make necessary adjustments. Stopping the TPN infusion abruptly could lead to complications from sudden nutrient deprivation. Administering insulin as prescribed may be necessary but should come after ensuring the correct TPN infusion rate. Notifying the healthcare provider is important but addressing the immediate need to check the infusion rate takes priority to manage hyperglycemia effectively.
