Correct Answer: B

Rationale: The correct answer is B. Clients taking diuretics are at risk for hyponatremia due to excessive sodium loss. In this scenario, a sodium level of 130 mEq/L indicates hyponatremia, which is commonly associated with diuretic use. Options A, C, and D are not the highest risk factors for developing low sodium levels in this context. Renal failure, hyperaldosteronism, and corticosteroid use are not directly linked to sodium loss as seen with diuretics.

Correct Answer: D

Rationale: Somogyi effect, also known as rebound hyperglycemia, occurs as a response to nighttime hypoglycemia. Eating a protein and carbohydrate snack at bedtime can help prevent this by stabilizing blood sugar levels throughout the night. Instructing the client to take insulin at 2:00 PM each day (Choice A) may not directly address the nighttime hypoglycemia concern. Engaging in physical activity daily (Choice B) is generally beneficial for diabetes management but may not specifically prevent Somogyi's effect. Increasing the dose of regular insulin (Choice C) without addressing the nighttime hypoglycemia issue can exacerbate the problem.

Correct Answer: C

Rationale: An ethical dilemma involves a situation where moral principles conflict, such as in the case of a parent wanting their adolescent to receive treatment against their will. In option A, a minor burn from spilled coffee does not present a conflict of moral principles. Option B describes a medical error, not necessarily a conflict of moral principles. Option D involves an issue of professional practice and patient safety but does not inherently pose a conflict of moral principles.

Correct Answer: A

Rationale: The correct answer is A: By using the Lund and Browder chart. The Lund and Browder chart is specifically designed to assess the extent of burns in children accurately, taking into account the variation in body proportions as children grow. This method provides a more precise estimation of the total body surface area affected by burns in pediatric patients. Choices B, C, and D are incorrect. The Rule of Nines is more suitable for adults, not children. The Rule of Tens is not a standard method for assessing burn extent, and the Parkland Formula is used to calculate fluid resuscitation requirements in burn patients, not to determine the extent of burns.

Correct Answer: B

Rationale: The primary goal of public health is to improve the health of populations by focusing on prevention, health promotion, and addressing the social determinants of health. Choice A is incorrect because public health looks at health from a population perspective rather than focusing on individual patient care. Choice C, while a potential benefit, is not the primary goal of public health. Choice D is incorrect as increasing hospital admissions is not a goal of public health; in fact, public health aims to prevent unnecessary hospitalizations through preventive measures.
