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: Correct Answer: Implementing strict hygiene protocols can help reduce healthcare-associated infections. By maintaining high standards of hygiene, such as proper handwashing, sterilization of equipment, and cleanliness of the environment, the spread of infections can be minimized. Choices A, C, and D are incorrect. Using outdated medical equipment can increase the risk of infections due to lack of proper maintenance and sterilization. Increasing patient wait times may lead to frustration but does not directly impact infection rates. Reducing nursing staff can compromise patient care and monitoring but is not specifically related to reducing healthcare-associated infections.

Correct Answer: C

Rationale: The correct answer is C: Kidney dialysis. A blood potassium level of 9.2 mEq/L indicates severe hyperkalemia, which can be life-threatening. Kidney dialysis is the most appropriate intervention to rapidly lower potassium levels in this situation. Choice A, intravenous potassium supplementation, would worsen the hyperkalemia. Choice B, intravenous calcium supplementation, is not the primary intervention for hyperkalemia. Choice D, parenteral nutrition, is unrelated to treating hyperkalemia and would not address the immediate concern.

Correct Answer: A

Rationale: The correct answer is A: 1 in 85 births. The rate of twin pregnancies is approximately 1 in 85 births. This means that twins are more common compared to triplets, which occur at a rate of 1 in 8,100 births. Choices B, C, and D are incorrect because they do not reflect the correct frequency of twin pregnancies as stated in the question.

Correct Answer: B

Rationale: Before delegating the task of bathing and turning a client with end-stage cancer to an experienced assistive personnel (AP), the nurse must assess specific client needs related to turning. This assessment ensures that the delegated care is tailored to the client's individual requirements, promoting safe and effective care. Option A is incorrect because the presence of the client's family is not directly related to assessing the client's specific needs for turning. Option C is incorrect as it refers to a different task (changing the central IV line dressing) and is not directly related to the turning assessment. Option D is incorrect as checking the client's pain level, although important, is not directly related to the specific needs related to turning the client.
