Correct Answer: A

Rationale: When observing a toddler in a playroom with other children, a caregiver would expect to witness parallel play. Parallel play is common among toddlers, where they play alongside but not directly with other children. This type of play is characterized by children engaging in similar activities near each other without interactive or cooperative play. Solitary play (Choice B) involves a child playing alone, while cooperative play (Choice C) involves children playing together towards a common goal. Competitive play (Choice D) involves activities where children compete against each other.

Correct Answer: D

Rationale: Promoting perianal skin integrity is crucial when caring for a young child with severe diarrhea to prevent skin breakdown from the irritation caused by frequent bowel movements. Maintaining the IV (Choice A) may be important for hydration but is not directly related to managing skin integrity. Taking daily weights (Choice B) is important for monitoring fluid balance but does not address the immediate need to prevent skin breakdown. While replacing lost calories (Choice C) is important, it is not the priority when a child is experiencing severe diarrhea and skin integrity is at risk.

Correct Answer: C

Rationale: The correct answer is C: Right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta are the cardiac defects associated with Tetralogy of Fallot. In Tetralogy of Fallot, these specific abnormalities contribute to the classic features of the condition. Choice A is incorrect as it includes mitral valve stenosis, which is not typically part of Tetralogy of Fallot. Choice B describes transposition of the great arteries, not Tetralogy of Fallot. Choice D mentions an altered connection between the pulmonary artery and the aorta, which is not a defining characteristic of Tetralogy of Fallot.

Correct Answer: D

Rationale: Explaining the use of prescribed medications is crucial because it helps ensure proper management of the child's condition after discharge. While teaching the parents about signs of infection and providing instructions on wound care are important aspects of postoperative care, they are not as critical as ensuring the correct understanding and administration of prescribed medications. Scheduling follow-up appointments is also important but does not directly impact the immediate post-discharge care and medication adherence.

Correct Answer: C

Rationale: Tetralogy of Fallot is characterized by a combination of four specific cardiac defects: right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta. Choice A is incorrect as it includes mitral valve stenosis, which is not typically part of tetralogy of Fallot. Choice B describes transposition of the great arteries rather than tetralogy of Fallot. Choice D includes an atrial septal defect, which is not part of the classic presentation of tetralogy of Fallot.
