Four hours following surgical repair of a compound fracture of the right ulna, the nurse is unable to palpate the client's right radial pulse. Which action should the nurse take first?

Correct Answer: B

Rationale: Completing a neurovascular assessment of the right hand is the priority in this situation. This assessment will help determine the circulation, sensation, and movement of the affected limb, ensuring there are no complications like compartment syndrome or impaired perfusion. Notifying the healthcare provider immediately (Choice A) might be necessary but should come after assessing the client's neurovascular status. Elevating the client's right hand (Choice C) can be helpful in some cases but should not precede a neurovascular assessment. Measuring the client's blood pressure and apical pulse rate (Choice D) is important but not the priority when assessing a potential vascular compromise in the limb.

Correct Answer: D

Rationale: In this scenario, the client is presenting with signs of sepsis, such as hypotension, hypothermia, and a recent history of partial-thickness burns with open wounds. The development of watery diarrhea further raises suspicion for sepsis. With a blood pressure of 82/40 mmHg and a low temperature of 96°F (36.6°C), the nurse should recognize the potential for septic shock. Notifying the rapid response team is crucial in this situation as the client requires immediate intervention and management to prevent deterioration and address the underlying septic process. Increasing the room temperature (Choice A) is not the priority as the low body temperature is likely due to systemic vasodilation and not environmental factors. While assessing oxygen saturation (Choice B) is important, the client's hypotension and hypothermia take precedence. Continuing to monitor vital signs (Choice C) alone is insufficient given the critical condition of the client and the need for prompt action to address the sepsis and potential septic shock.

Correct Answer: B

Rationale: The correct answer is B: Moon face. Cushing's syndrome is characterized by excess cortisol levels, leading to the distinctive round and full face known as moon face. Hyperpigmentation (choice A) may occur due to increased ACTH levels, but it is not a hallmark symptom like moon face. Hypotension (choice C) is less common in Cushing's syndrome as cortisol typically leads to hypertension (choice D) due to its effects on blood pressure regulation.

Correct Answer: C

Rationale: Sweating is a common sign of hypoglycemia in diabetic patients. When blood sugar levels drop too low, the body releases stress hormones like adrenaline, which can cause sweating as a response to the perceived danger. Polydipsia (excessive thirst) and polyuria (excessive urination) are actually more commonly associated with hyperglycemia, not hypoglycemia. Dry skin is not typically a sign of hypoglycemia.

Correct Answer: A

Rationale: The correct answer is Atherosclerosis. It is the primary cause of coronary artery disease, as it involves the buildup of plaque in the arteries, restricting blood flow to the heart. Hyperlipidemia (choice B) contributes to atherosclerosis by increasing cholesterol levels in the blood but is not the direct cause of coronary artery disease. Diabetes (choice C) can accelerate atherosclerosis due to high blood sugar levels, but it is not the most common cause. Smoking (choice D) is a significant risk factor for developing coronary artery disease but is not the primary cause.
