Correct Answer: B

Rationale: The correct answer is B: 'Avoid gluten.' Children with celiac disease must follow a gluten-free diet to prevent symptoms and intestinal damage. Gluten is a protein found in wheat, barley, and rye, which triggers an immune response in individuals with celiac disease. Choices A, C, and D are incorrect because while some individuals with celiac disease may also have lactose intolerance or may need to manage fat or sugar intake for overall health, the primary dietary restriction for celiac disease is avoiding gluten to maintain gastrointestinal health.

Correct Answer: D

Rationale: A low-phenylalanine diet is necessary for infants with PKU because it helps prevent the accumulation of phenylalanine, which can result in brain damage. Fat-free (Choice A) and protein-enriched (Choice B) diets are not specifically indicated for PKU. While phenylalanine-free (Choice C) may seem logical, complete elimination of phenylalanine is not practical or safe as it is an essential amino acid. Therefore, the correct choice is a low-phenylalanine diet, which restricts phenylalanine intake to a safe level.

Correct Answer: A

Rationale: The correct answer is A: 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. Rest is crucial as it allows the child's body to fight the infection and recover. Choice B, Exercise, would not be appropriate as the child needs rest to conserve energy and promote healing. Choice C, Nutrition, is important for overall health but may not be the immediate priority when the child is acutely ill with pneumonia. Choice D, Elimination, is important but is not the priority need in this scenario compared to ensuring rest to aid recovery from pneumonia.

Correct Answer: B

Rationale: The correct answer is "B: Rolls over." At 6 months, most infants can roll over, which increases the risk of falls. Emphasizing the infant's ability to roll over is crucial to highlight the need for careful supervision and accident prevention. Choices A, C, and D are incorrect because sitting up, crawling short distances, and standing while holding on to furniture typically develop later in an infant's motor skills progression and are not as directly associated with an increased risk of accidents at this stage.

Correct Answer: C

Rationale: Scheduling the visit at a time that is convenient for the family is crucial for ensuring the family's receptiveness and availability, making the visit more productive. Choosing a time when the mother is feeding the infant (choice B) may not necessarily align with the family's overall convenience and may disrupt the feeding routine. Similarly, scheduling the visit when the husband is out of the home (choice A) might not be optimal as it may exclude an important family member and potentially impact the support system. While spending time with the family (choice D) is important, the primary focus should be on accommodating the family's schedule to maximize the effectiveness of the visit.
