Correct Answer: B

Rationale: A macule is defined as a flat, discolored area on the skin that is different from surrounding tissue due to a change in color. In this case, the baby has a flat, discolored area on the skin, which fits the description of a macule. A papule is a small, raised solid bump, a vesicle is a small fluid-filled blister, and a scale is a flake of skin that is often dry and rough. Therefore, choices A, C, and D do not accurately describe the flat, discolored area on the baby's skin, making them incorrect.

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: After undergoing surgery for pectus excavatum correction with steel bar placement, 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, which could compromise the surgical outcome. Semi-Fowler, supine, and high Fowler positions do not pose the same risk of displacing the steel bar and are generally safe and comfortable for the child in this postoperative period.

Correct Answer: C

Rationale: Ineffective sucking and swallowing can be early signs of a heart defect like a ventricular septal defect. This is crucial information for the nurse to consider as it aligns with the infant's tentative diagnosis. Choice A is too general and does not provide specific relevance to the situation. Choice B is incorrect as inadequate sucking can indeed be significant, especially in the context of a potential heart defect. Choice D is not directly related to the potential heart defect and feeding difficulties mentioned in the scenario.

Correct Answer: A

Rationale: Projectile vomiting is a classic clinical manifestation of pyloric stenosis in infants. This occurs due to the narrowing of the pyloric sphincter, leading to the forceful expulsion of gastric contents in a projectile manner. Diarrhea (choice B) is not typically associated with pyloric stenosis. Constipation (choice C) is also not a common symptom of this condition. Abdominal distension (choice D) may occur in pyloric stenosis but is not as specific or characteristic as projectile vomiting in diagnosing this condition.
