Correct Answer: B

Rationale: The correct answer is B. Live vaccines like MMR should not be given to immunosuppressed infants because their weakened immune systems may not handle the vaccine safely. Choice A is incorrect as delaying the MMR vaccine until the infant reaches 2 years of age does not address the issue of immunosuppression. Choice C is incorrect because administering live vaccines to an immunosuppressed individual could lead to serious complications. Choice D is incorrect as immediate action is required to prevent potential harm to the immunosuppressed infant.

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: 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: C

Rationale: The correct dietary instruction for a child with GERD is to avoid high-fat foods. High-fat foods can relax the lower esophageal sphincter, leading to increased reflux. While avoiding gluten may be necessary for individuals with gluten sensitivity or celiac disease, it is not a standard recommendation for GERD. Avoiding spicy foods and dairy products may help some individuals with GERD, but the most crucial dietary advice is to avoid high-fat foods.

Correct Answer: C

Rationale: In a 5-year-old child who is unconscious with a respiratory rate of 8 breaths/min and a heart rate of 50 beats/min, the priority is to initiate chest compressions, artificial ventilations, and rapid transport. These vital interventions are crucial in cases of severe respiratory and cardiovascular compromise. Choice A is incorrect because administering 100% oxygen alone may not address the underlying issues of inadequate ventilation and circulatory support. Choice B is not the most appropriate initial intervention in this scenario; chest compressions should precede positive pressure ventilations. Choice D is incorrect as back blows and chest thrusts are indicated in choking emergencies, not in this case of respiratory and cardiovascular compromise.
