Correct Answer: D

Rationale: Macaroni and cheese and Cheerios are appropriate choices for a 30-month-old toddler on a regular diet. These foods are easy to chew, digest, and are generally well-liked by toddlers. Option A, a hamburger with bun and grapes, may be difficult for a toddler to handle due to the size of the hamburger and grapes pose a choking hazard. Option B, chicken fingers and french fries, may be too greasy and processed for a toddler's developing digestive system. Option C, hot dog with bun and potato chips, is also not ideal as hot dogs can be a choking hazard and potato chips are high in salt and may not provide adequate nutrition.

Correct Answer: C

Rationale: In this scenario, the nurse should consider that ineffective sucking and swallowing in a 2-week-old infant could be early signs of a heart defect such as a ventricular septal defect. This is crucial information as it can guide further assessment and management. Choice A is incorrect because while feeding problems can be common in neonates, in this case, the specific context of a suspected heart defect should be prioritized. Choice B is incorrect as inadequate sucking can indeed be significant, especially when considering potential underlying heart issues, regardless of the presence of cyanosis. Choice D is incorrect as while mucus retention can affect feeding, in this case, the focus should be on the possibility of a heart defect rather than a temporary issue like mucus interference.

Correct Answer: B

Rationale: When parents of a toddler request to be present during a procedure, an individual assessment of the parents is crucial. This assessment helps healthcare professionals understand the parents' ability to cope with the situation, provide support to their child, and ensure a conducive environment for the procedure. Choice A is not as critical because the focus is on the parents' readiness rather than the specific procedure. Choice C, considering the toddler's desire, is important but not as crucial as assessing the parents. Choice D, anticipating the toddler's response to pain, is relevant but secondary to assessing the parents' readiness and support capabilities.

Correct Answer: D

Rationale: The correct answer is D. Novolin N insulin peaks in the evening, leading to a higher risk of hypoglycemia during this time. Providing a snack before bedtime helps counteract the late insulin activity and prevent hypoglycemia. Choice A is incorrect as the primary reason for the snack is related to insulin activity rather than diet compliance. Choice B is not directly related to the timing of Novolin N insulin administration. Choice C is unrelated to the specific need for a snack in the evening to address insulin activity.

Correct Answer: B

Rationale: The correct answer is B: 'Ensure that the antibiotic is administered as prescribed.' It is crucial for the parents to follow the prescribed antibiotic regimen to prevent infections and promote proper healing following cardiac surgery. Option A is incorrect because the timing of antibiotic administration may vary depending on the specific medication and instructions. Option C is not necessary and could potentially affect the antibiotic's effectiveness. Option D is not relevant to the administration of the antibiotic and does not ensure proper usage.
