Correct Answer: A

Rationale: The correct answer is A: Start an IV infusion of normal saline. The client is showing signs of dehydration, such as abdominal cramping, vomiting, lethargy, and confusion, which can be exacerbated by hyperglycemia. Rehydration is the initial priority to address the fluid imbalance. Option B, obtaining a serum potassium level, though important in the management of diabetes, is not the immediate priority over rehydration. Option C, administering the client's usual dose of insulin, should only be done after addressing the dehydration and confirming the client's blood glucose levels. Option D, assessing the pupillary response to light, is not the most urgent intervention needed in this situation compared to rehydration to correct fluid imbalance.

Correct Answer: D

Rationale: Corrected Rationale: Blurred vision or seeing yellow halos around objects are signs of digoxin toxicity, which can be life-threatening. These symptoms indicate an overdose of digoxin, requiring immediate medical attention. Muscle weakness and fatigue (Choice A) are not typically associated with digoxin toxicity. Increased appetite and weight gain (Choice B) are not indicative of digoxin toxicity either. Nausea and vomiting (Choice C) are common side effects of digoxin but are not specific signs of toxicity. Therefore, the correct answer is to monitor for blurred vision or seeing yellow halos around objects.

Correct Answer: D

Rationale: The correct response for the nurse in this situation is to discuss the boundaries of the therapeutic relationship with the client. By doing so, the nurse can reinforce professionalism, establish clear boundaries, and prevent ethical conflicts. Option A is incorrect because avoiding the client or unit does not address the issue at hand and may compromise patient care. Option B, while acknowledging the behavior, does not address the underlying reasons and boundaries. Option C, stating hospital policy, is not as therapeutic or client-centered as discussing the therapeutic relationship directly.

Correct Answer: B

Rationale: The correct answer is to position the child sitting up and leaning forward. This position helps prevent blood from flowing down the throat, reducing the risk of choking or vomiting. Choice A is incorrect because lying flat can cause blood to flow down the throat. Choice C is wrong as tilting the head back may lead to blood entering the throat. Choice D is also incorrect as applying ice is not recommended for nosebleeds and lying on the side may not prevent blood from flowing down the throat.

Correct Answer: A

Rationale: The correct answer is A: Frequent exercise and weight control. These should be emphasized as a goal for all diabetics because they help prevent complications and manage blood sugar levels. Regular physical activity and maintaining a healthy weight are crucial in managing diabetes as they can improve insulin sensitivity, regulate blood sugar levels, and reduce the risk of cardiovascular complications. Choice B, preventing eye damage, is important but is more specific to diabetic retinopathy and not a general goal for all diabetics. Choice C, keeping insulin refrigerated, is essential for insulin storage but not a primary goal for all diabetics. Choice D, preventing the development of complications, is too broad and does not provide a specific actionable goal for all diabetics.
