Correct Answer: B

Rationale: Assessing the child's dietary intake is crucial as certain foods and additives can affect ADHD symptoms. Ensuring a balanced diet can help manage symptoms and provide proper nutrition. Assessing sleep patterns (Choice A) is also important, but dietary intake is more directly linked to symptom management in ADHD. Academic performance (Choice C) and behavior at home (Choice D) may be affected by ADHD but are not as directly related to medication management as dietary intake.

Correct Answer: A

Rationale: The correct answer is A: 'On the back, lying flat'. Placing infants on their back to sleep is recommended to reduce the risk of sudden infant death syndrome (SIDS). This position helps ensure the baby's airway remains clear and reduces the likelihood of suffocation. Choices B, C, and D are not as safe as placing the infant on their back, as they may increase the risk of accidental suffocation or SIDS.

Correct Answer: A

Rationale: Abdominal swelling is a classic presentation and often the first noticeable sign of a Wilms tumor. This occurs due to the tumor mass in the kidney, leading to abdominal distension. Weight gain (Choice B) is less likely as a presenting symptom compared to abdominal swelling. Hypotension (Choice C) is not typically associated with a Wilms tumor unless complications like bleeding or shock occur. Increased urinary output (Choice D) is not a typical finding for Wilms tumor; instead, patients may present with hematuria or urinary symptoms.

Correct Answer: C

Rationale: Following surgery for hypertrophic pyloric stenosis (HPS) in infants, it is appropriate to resume regular formula feeding within 24 hours postoperatively to support recovery. This helps maintain adequate nutrition and hydration for the infant. Choice A is incorrect because thickened formula may not be necessary and could potentially cause issues postoperatively. Choice B is incorrect as withholding feedings for the first 24 hours can lead to nutritional deficiencies and delay recovery. Choice D is inappropriate as additional glucose feedings are not typically indicated postoperatively for infants with HPS and may not provide the necessary nutrition needed for recovery.

Correct Answer: B

Rationale: Lifting the baby from under the armpits can cause fractures in infants with osteogenesis imperfecta. The correct approach is to support the baby's body and head carefully, avoiding pressure on vulnerable areas prone to fractures. Choices A, C, and D demonstrate proper awareness of caring for an infant with osteogenesis imperfecta by emphasizing caution to prevent fractures.
