Correct Answer: D

Rationale: The correct answer is D. Children with celiac disease must strictly adhere to a gluten-free diet. Even small amounts of gluten can cause harm by triggering an immune response that damages the intestines. It is crucial for parents to understand that allowing their child to have small amounts of gluten occasionally is not safe and can lead to complications. Therefore, further teaching is needed to emphasize the importance of complete avoidance of gluten-containing foods for a child with celiac disease. Choices A, B, and C demonstrate understanding of the need to avoid gluten-containing foods and hidden sources of gluten, which are essential in managing celiac disease. Choice D is incorrect as it suggests a lax approach to the child's diet, which can be harmful in the case of celiac disease.

Correct Answer: D

Rationale: Providing positive feedback to the mother for correctly administering the iron supplements is essential as it reinforces proper medication administration practices. This encouragement can help build the mother's confidence and ensure that she continues to administer the supplements correctly in the future, promoting the infant's health and well-being. Choices A, B, and C are incorrect because there is no need to suggest altering the administration method, changing the liquid used, or restricting feeding immediately after administering the iron supplement. Giving positive feedback is the most appropriate action in this scenario to acknowledge the mother's correct administration technique.

Correct Answer: B

Rationale: Teaching children how to swim is valuable, but parental supervision around water is essential to prevent drowning. It's crucial to emphasize constant supervision when young children are near water, regardless of their swimming abilities. The other choices (A, C, and D) demonstrate appropriate safety measures for injury prevention in toddlers, such as securing cleaning supplies, ensuring helmet use during tricycle rides, and using a car seat for every car ride.

Correct Answer: C

Rationale: The most appropriate initial action for the nurse to take is to inspect the child's ears for drainage. This step can provide immediate information on the presence of infection or fluid, which could be impacting the child's hearing. By assessing for drainage, the nurse can gather valuable initial data to determine the next course of action, such as further evaluation or treatment. Asking about speech development or referring to an audiologist would be secondary steps after assessing the physical condition of the ears. Performing a hearing test would also be premature without first examining the ears for any visible issues.

Correct Answer: C

Rationale: When administering azithromycin IV, monitoring for signs of an allergic reaction, such as facial swelling or urticaria, is crucial. This helps in early detection of potential adverse reactions and ensures prompt intervention to prevent complications associated with the medication. The other options are not directly related to the administration of azithromycin IV in this scenario. Monitoring for fluid overload would be more relevant for fluid administration, changing IV site dressing is important but not the priority in this case, and assessing for abdominal pain and vomiting may be important but not as critical as monitoring for signs of an allergic reaction.
