A client with a history of chronic kidney disease is receiving erythropoietin therapy. Which finding indicates that the therapy is effective?

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 B) reflects the bone marrow's response to anemia but does not directly confirm the effectiveness of erythropoietin therapy. Blood pressure (choice C) and serum ferritin level (choice D) are not specific indicators of the effectiveness of erythropoietin therapy for chronic kidney disease.

Correct Answer: D

Rationale: In a client with acute pancreatitis and a history of alcohol abuse, a temperature of 101°F (38.3°C) can indicate infection, which is a serious complication requiring immediate intervention. Elevated amylase and lipase levels are common in acute pancreatitis but do not directly indicate the need for urgent intervention. A calcium level of 8.5 mg/dL is within the normal range and does not require immediate action in this context.

Correct Answer: B

Rationale: Dizziness after hemodialysis can indicate hypovolemia, hypotension, or other complications that require immediate intervention to prevent further deterioration or adverse events. Weight gain of 2 pounds may not be immediately concerning post-hemodialysis. A blood pressure of 150/90 mm Hg is slightly elevated but may not require immediate intervention unless accompanied by symptoms. A heart rate of 88 beats per minute falls within the normal range and may not be an immediate cause for concern after hemodialysis.

Correct Answer: D

Rationale: Chest pain radiating to the left arm is a classic symptom of a myocardial infarction (heart attack) in individuals with coronary artery disease. This finding indicates that the heart muscle may not be receiving adequate oxygen, which requires immediate intervention to prevent further damage or complications. The other assessment findings (heart rate of 90 beats per minute, respiratory rate of 20 breaths per minute, blood pressure of 130/80 mm Hg) are within normal limits and do not suggest an acute, life-threatening condition like myocardial infarction.

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.
