Correct Answer: D

Rationale: Acknowledging the child's anger as a coping mechanism helps validate their feelings and can open a dialogue for further support.

Correct Answer: B

Rationale: The findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.

Correct Answer: A

Rationale: To calculate the correct dose for each administration, you first need to find the total daily dose: 300 mg/kg * 25 kg = 7500 mg/day. Since this total dose is divided into equally divided doses every 4 hours, there are 6 doses in 24 hours. Therefore, 7500 mg · 6 doses = 1250 mg per dose. The nurse should administer 1250 mg every 4 hours, resulting in a total of 1875 mg for each dose in a 24-hour period. Choice A, 1875 mg, is the correct answer. Choice B, 625 mg, is incorrect as it does not consider the total daily dose and the frequency of administration. Choice C, 2000 mg, is incorrect as it is not the calculated dosage based on the given parameters. Choice D, 1500 mg, is also incorrect as it does not reflect the correct dosage calculation for each dose.

Correct Answer: C

Rationale: Children with von Willebrand disease have a deficiency in a clotting protein, putting them at risk of bleeding episodes. The priority nursing intervention for a child with von Willebrand disease is to guard against bleeding injuries to prevent excessive bleeding or hemorrhage. Choices A, B, and D are not the priority interventions for von Willebrand disease. While reducing exposure to infection is important for any hospitalized child, it is not the priority for von Willebrand disease. Eliminating contact with cold objects is more relevant for conditions like Raynaud's disease. Reducing contact with other children is not a specific priority related to managing von Willebrand disease.

Correct Answer: B

Rationale: The most effective way to prevent hypoglycemia during physical activity in a child with type 1 diabetes is to ensure they eat a snack before exercising. Eating a snack before exercise helps maintain blood glucose levels by providing additional glucose for energy during physical activity, reducing the risk of hypoglycemia. Giving extra insulin before exercise (Choice A) can increase the risk of hypoglycemia as it lowers blood glucose levels further. Limiting physical activity (Choice C) is not recommended as exercise is important for overall health. Monitoring blood glucose levels after exercise (Choice D) is essential but does not directly prevent hypoglycemia during physical activity.
