Rationale: Macaroni and cheese and Cheerios are appropriate choices for a 30-month-old toddler on a regular diet as they provide a balance of carbohydrates and protein. Option A, hamburger with bun and grapes, may be difficult for a toddler to chew, and grapes pose a choking hazard. Option B, chicken fingers and french fries, are high in unhealthy fats and sodium. Option C, hot dog with bun and potato chips, are processed foods high in salt and unhealthy fats, not ideal for a toddler's diet.

Correct Answer: D

Rationale: The correct answer is D: Side-lying. After surgery using steel bar placement to correct pectus excavatum, the nurse should instruct the parents to avoid placing the child in a side-lying position. This position should be avoided to prevent displacement of the steel bar. Choices A, B, and C are incorrect. Semi-Fowler, Supine, and High Fowler positions are generally safe and commonly used in postoperative care, but in this specific case, side-lying should be avoided to ensure the effectiveness of the surgical correction.

Correct Answer: C

Rationale: In cases where child abuse is suspected, it is crucial to prioritize the safety and well-being of the child. Advising the parents that the child needs to be transported allows for the child to receive necessary medical care without immediate confrontation. Calling the police to have the parents arrested (Choice B) may escalate the situation and should only be done after ensuring the child's safety. Informing the parents of suspicions (Choice A) may potentially place the child at further risk if the parents are the abusers. Transporting the child to the hospital regardless of the parents' wishes (Choice D) could lead to legal and ethical complications; it is important to involve the appropriate authorities and handle the situation with sensitivity and care.

Correct Answer: A

Rationale: In this scenario, the 4-year-old is presenting with signs of airway compromise due to the fall. After performing a jaw-thrust maneuver to open the airway while stabilizing the head to prevent further injury, the next step should be to suction the oropharynx. Suctioning helps to clear any blood or secretions from the mouth and throat, ensuring a clear airway for proper breathing. Inserting a nasopharyngeal airway or initiating positive pressure ventilations would be premature without first ensuring the airway is clear. Placing the patient in the recovery position is not indicated at this point as the focus should be on managing the airway.
