Correct Answer: C

Rationale: Scheduling the visit at a time that is convenient for the family is the most appropriate choice. This ensures that the family is receptive and available, making the visit more productive. Choice A is incorrect because the presence of the husband may be important for support and decision-making. Choice B focuses solely on the mother and the infant's feeding time, which may not align with the family's overall availability. Choice D is incorrect as it emphasizes the nurse's convenience rather than the family's, which may not lead to an effective visit.

Correct Answer: D

Rationale: The most crucial factor in the process of toilet training is the parents' willingness to consistently engage and work with their child. While parents' attitude and the child's desire to remain dry can influence the process, the key to successful toilet training lies in the parents' commitment and effort. The child's ability to sit still on the toilet is important but not as critical as the parents' active involvement and support in guiding and encouraging the child through the training process.

Correct Answer: C

Rationale: In pyloric stenosis, a palpable olive-like mass in the abdomen is a classic finding. This mass is due to the hypertrophied pyloric muscle. Abdominal rigidity (choice A) is associated with conditions like peritonitis, substernal retraction (choice B) is typically seen in respiratory distress, and marked distention of the lower abdomen (choice D) is more characteristic of conditions like intestinal obstruction rather than pyloric stenosis.

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: A

Rationale: The correct answer is Rest. When a child is admitted to the hospital with pneumonia, the priority need in the nursing plan of care is to ensure adequate rest for the child. Rest is crucial as it allows the child's body to fight the infection and recover. Choice B, Exercise, is incorrect as strenuous physical activity may further strain the child's respiratory system. Choice C, Nutrition, is important but providing rest takes precedence initially. Choice D, Elimination, is not the priority concern in this scenario compared to ensuring rest for recovery from pneumonia.
