Correct Answer: C

Rationale: In a child with nephrotic syndrome experiencing sudden weight gain, the priority action for the nurse is to notify the healthcare provider. This weight gain could indicate worsening edema or fluid retention, necessitating immediate medical evaluation and intervention. The healthcare provider can conduct a comprehensive assessment, order necessary tests, and adjust the treatment plan accordingly. Administering a diuretic, restricting fluid intake, or measuring abdominal girth should not be initiated without healthcare provider consultation to ensure appropriate management of the child's condition.

Correct Answer: A

Rationale: The correct answer is A because a low red blood cell count may indicate anemia, which could pose risks during surgery. Anemia can affect oxygen delivery to tissues, impacting wound healing and overall surgical outcomes. The other options, such as white blood cell count, weight gain, and urine specific gravity, are less critical for immediate surgical considerations. White blood cell count is more related to infection risk postoperatively rather than immediate surgical risk. Weight gain reflects good overall growth but does not impact the immediate surgical situation. Urine specific gravity is more indicative of hydration status rather than immediate surgical risk.

Correct Answer: B

Rationale: Choice B is not the appropriate response in this scenario. The correct answer is choice A, which normalizes the situation for the child by reminding him that his mother breastfed him too. This response helps the older brother understand that breastfeeding is a natural and common practice for newborns, including his baby sister, just as it was for him when he was a baby. Choice B, while true, does not directly address the child's question and may not provide the same level of reassurance and normalization as choice A. Choices C and D also do not directly answer the child's question and do not provide the same level of connection and understanding as choice A.

Correct Answer: A

Rationale: In this scenario, the best course of action for the nurse is to review the child's asthma action plan. By doing so, the nurse can assess the current asthma management, ensure that the child is using the rescue inhaler correctly, and make any necessary adjustments to the treatment plan. Reviewing the asthma action plan helps in identifying triggers, proper use of medications, and when to seek medical help. Administering a dose of the rescue inhaler without assessing the current management plan may not address the underlying issue. Instructing the parents to increase the dose of the controller medication without proper evaluation can lead to inappropriate medication adjustments. Scheduling a follow-up appointment in one week is not the immediate action needed to address the child's current symptoms.

Correct Answer: C

Rationale: Intravenous fluids are typically the initial intervention in diabetic ketoacidosis (DKA) to treat dehydration and stabilize the patient's condition. The fluid replacement helps correct electrolyte imbalances and improve perfusion, which are crucial in managing DKA. Insulin therapy follows after fluid resuscitation to address the underlying cause of DKA, which is the lack of insulin leading to increased ketone production. Administering subcutaneous insulin (Choice A) would be premature without first addressing the dehydration and electrolyte imbalances. Giving oral glucose tablets (Choice B) is contraindicated in DKA as the patient already has high blood glucose levels. Administering oxygen therapy (Choice D) may be necessary based on the patient's condition, but addressing dehydration with intravenous fluids is the priority intervention in DKA.
