Correct Answer: B

Rationale: A hemoglobin A1c of 8.5% indicates suboptimal diabetes control. The most appropriate action for the nurse in this scenario is to review the child's dietary habits and insulin administration technique. This approach can help identify potential areas for improvement and optimize diabetes management, aiming to lower the hemoglobin A1c levels towards the target range. Increasing the child's insulin dose (Choice A) without addressing dietary habits and administration technique may not lead to better control and can increase the risk of hypoglycemia. Switching to oral hypoglycemics (Choice C) is not appropriate for type 1 diabetes management. Scheduling a follow-up appointment in three months (Choice D) without intervening to improve diabetes control is not the best immediate action.

Correct Answer: B

Rationale: The correct answer is B. Introducing solid foods 4 to 7 days apart is crucial as it allows time to identify any allergic reactions or intolerances to specific foods. This gradual introduction helps parents monitor their infant's response to new foods and pinpoint any potential issues, ensuring the infant's safety and well-being. Choices A, C, and D are incorrect because starting with one tablespoon of the food, mixing new food with rice cereal, and removing foods when the infant refuses them are not recommended practices for introducing solid foods to infants.

Correct Answer: A

Rationale: When dealing with seborrheic dermatitis (cradle cap) in infants, it is essential to use a soft brush and gently scrub the affected area to help remove the scales. This process can aid in managing the condition and preventing further build-up. It is important to be gentle to avoid irritating the baby's delicate skin. Choice B is incorrect as gentle scrubbing with a soft brush can help in the removal of scales. Choice C is incorrect because regular but gentle washing is recommended to manage cradle cap. Choice D is incorrect as using specialized shampoos designed for cradle cap is usually recommended over soap and water.

Correct Answer: D

Rationale: It is crucial for the nurse to educate the mother that giving pain medication around the clock helps manage pain effectively and improves the child's quality of life. This approach ensures a more consistent level of pain relief and prevents the pain from becoming severe, which can be more challenging to manage. Choices A, B, and C do not address the importance of consistent pain management and may not provide adequate relief for the child's condition.

Correct Answer: A

Rationale: In a case of diabetic ketoacidosis (DKA), the primary feature is elevated blood glucose levels due to insulin deficiency. Additionally, ketones are increased in the blood and urine. Bicarbonate levels are usually low because of the metabolic acidosis that accompanies DKA. Therefore, the practical nurse should anticipate elevated blood glucose levels as a characteristic laboratory finding in a child admitted with DKA. Choice B is incorrect because serum ketones are increased in DKA. Choice C is incorrect because in DKA, urine glucose is typically high due to spillage of glucose into the urine. Choice D is incorrect because bicarbonate levels are usually low in DKA, not high.
