Correct Answer: B

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, elevated blood pressure is the most concerning finding. Elevated blood pressure can indicate worsening hypertension, which requires immediate intervention to prevent further damage to the kidneys and other organs. Increased fatigue (choice A) is a common symptom in CKD but may not be as acutely concerning as elevated blood pressure. Elevated hemoglobin (choice C) can be an expected outcome of erythropoietin therapy and is not necessarily concerning. Low urine output (choice D) is important to monitor in CKD but may not be as immediately concerning as elevated blood pressure in this context.

Correct Answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range to prevent both bleeding and clotting events. Choices B, C, and D are incorrect because while PT is used to monitor warfarin therapy, INR is a more precise indicator of therapeutic levels. Serum sodium level and hemoglobin level are not directly related to monitoring warfarin therapy.

Correct Answer: C

Rationale: A serum potassium level of 3.0 mEq/L should be monitored closely in a client who is postoperative following a thyroidectomy to detect any electrolyte imbalances. After a thyroidectomy, there is a risk of hypokalemia due to the effects of anesthesia, stress response, and the surgical procedure itself. Monitoring serum potassium levels is crucial as hypokalemia can lead to cardiac arrhythmias and muscle weakness. Serum calcium, sodium, and chloride levels are important but not the primary focus following a thyroidectomy, making them incorrect choices.

Correct Answer: A

Rationale: The correct answer is A: Distal pulse intensity. Monitoring distal pulses is crucial to ensure that circulation to the extremity is not compromised. This assessment helps in detecting any signs of decreased circulation, which is vital in managing a burned extremity. While skin integrity (choice B), pain levels (choice C), and range of motion (choice D) are also important assessments, monitoring distal pulse intensity takes precedence as it directly reflects the perfusion status of the affected extremity in a burned client.

Correct Answer: A

Rationale: Severe abdominal distention is a sign of worsening pancreatitis and can indicate complications like bowel obstruction or fluid accumulation. Immediate intervention is necessary to prevent further deterioration. Decreased urine output (Choice B) could indicate renal impairment, decreased bowel sounds (Choice C) are expected in pancreatitis due to paralytic ileus, and an increased heart rate (Choice D) is a common response to pain or stress in acute pancreatitis but may not require immediate intervention unless it is extremely high or persistent.
