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: 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: D

Rationale: The Moro reflex, also known as the startle reflex, is typically present in infants up to around 4-6 months of age and is characterized by the infant's response to a sudden loss of support or loud noise. It is not a normal finding in adolescents or older individuals. Therefore, if an adolescent patient exhibits the Moro reflex during a neurological assessment, it is considered abnormal and warrants further evaluation. Choices A, B, and C are incorrect because the Moro reflex is not expected or normal among adolescents and does not specifically indicate the status of either the peripheral or central nervous system in this age group.

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: D

Rationale: Using clean gloves rather than sterile gloves for colostomy care is a cost-effective measure without compromising care quality. This choice helps in reducing costs without compromising patient safety. Storing opened bottles of normal saline in a refrigerator for up to 48 hours (Choice A) may lead to contamination risks. Returning unused supplies to the unit's supply stock (Choice B) can be inefficient and lead to potential waste. Waiting to dispose of sharps containers until they are completely full (Choice C) may pose safety hazards and not directly impact cost savings.
