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.

Correct Answer: A

Rationale: The correct intervention for a child with Kawasaki disease, presenting with irritability and skin peeling, is to place the child in a quiet environment. This helps reduce environmental stimuli, calming the child and aiding in managing the symptoms associated with the disease. Choice B is incorrect as addressing food preferences is not the priority in this situation. Choice C is incorrect as the focus should be on the child's immediate needs. Choice D is incorrect as applying lotion is not the first-line intervention for Kawasaki disease symptoms.

Correct Answer: A

Rationale: In a client with type 1 diabetes presenting with hyperglycemia (blood glucose level of 400 mg/dL) and symptoms of thirst and frequent urination, the priority action for the nurse is to administer insulin as prescribed. Insulin helps lower the blood glucose level and prevents complications like diabetic ketoacidosis. While encouraging hydration is essential, administering insulin is crucial to address the high blood glucose levels. Checking urine for ketones is important in diabetic management but is secondary to administering insulin in this scenario. Reinforcing diet and exercise importance is vital for diabetes management but not the priority in acute hyperglycemia.

Correct Answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario. The nurse obtained an apical heart rate of 128 bpm, which is within the expected range for a 2-year-old child. Therefore, there is no immediate concern to withhold the scheduled dose of digoxin. Determining the pulse deficit is not necessary as the heart rate is appropriate. Calculating the safe dose range is not needed as the current dose is within the therapeutic range. Reviewing the serum digoxin level may be indicated later for monitoring but is not urgent based on the heart rate assessment. Administering the scheduled dose of digoxin is the correct action at this time.

Correct Answer: B

Rationale: The correct answer is to notify the healthcare provider immediately. The child's presentation of sudden, severe abdominal pain in the lower right abdomen is highly concerning for appendicitis, a medical emergency. Promptly notifying the healthcare provider is crucial for further evaluation and management. Administering pain medication as the first action might mask symptoms and delay diagnosis. Starting an IV line for fluid administration and obtaining a complete blood count are important interventions but should come after healthcare provider notification.
