Correct Answer: D

Rationale: When dealing with a client with anorexia nervosa who insists on working out constantly, it is crucial to address the situation sensitively. Speaking to the client privately to uncover the source of the obsession is the most appropriate action. This approach allows the healthcare professional to understand the underlying reasons for the behavior and work towards a solution together. Choices A and B could potentially exacerbate the client's condition by either enabling the behavior or imposing restrictions without addressing the root cause. While choice C is important, simply discussing the risks may not address the client's compulsion to exercise excessively.

Correct Answer: B

Rationale: The correct answer is B: Administer insulin before meals as prescribed. This is the most important teaching point because insulin administration before meals helps manage blood sugar effectively in diabetic patients. Choice A is incorrect because monitoring blood sugar levels weekly may not provide timely information for managing diabetes. Choice C is incorrect as medications for diabetes should be taken as prescribed, not only when feeling unwell. Choice D is incorrect as blood sugar levels should be monitored at various times throughout the day, not just in the morning, to get a complete picture of the patient's condition.

Correct Answer: B

Rationale: The most important point to emphasize when teaching a client with diabetes about insulin administration is to administer insulin before meals as prescribed. This is crucial for maintaining proper blood sugar control throughout the day. Choice A is incorrect because blood sugar levels need to be monitored multiple times a day, not just once in the morning. Choice C is incorrect because insulin should be administered according to the prescribed schedule, not only when feeling unwell. Choice D is incorrect because blood sugar monitoring should be done at various times during the day, not just in the evening.

Correct Answer: A

Rationale: The correct answer is A: Diabetic ketoacidosis and dehydration. Untreated hyperglycemia can lead to diabetic ketoacidosis, a serious complication characterized by high blood sugar, the presence of ketones in the urine, and acidosis. Dehydration is also a common complication of untreated hyperglycemia. Choices B, C, and D are incorrect because hypoglycemia and hypertension are not typical complications of untreated hyperglycemia. Infection and liver failure, as well as pulmonary edema and electrolyte imbalance, are also not direct complications of untreated hyperglycemia.

Correct Answer: A

Rationale: Administering oxygen and calling for emergency assistance are the immediate priorities when managing a suspected pulmonary embolism. Oxygen helps support the patient's respiratory function, while emergency assistance is crucial for further evaluation and treatment. Positioning the patient in a prone position or giving fluids can worsen the condition by impeding blood flow. Administering anticoagulants may be part of the treatment plan but is not the initial response. Thrombolytics and chest physiotherapy are not first-line treatments for suspected pulmonary embolism and can even be harmful without prior evaluation.
