Correct Answer: D

Rationale: The correct answer is D. Pain is frequently reported by children with cancer, with around 84% experiencing it. Most children report moderate to severe pain, with about half finding it highly distressing. There is no evidence to suggest that children often misrepresent their pain experiences. Pain tolerance is not solely based on age but is a complex phenomenon. Children do not become accustomed to painful procedures, as each experience of pain is unique.

Correct Answer: D

Rationale: N-acetylcysteine is the specific antidote for acetaminophen poisoning, working by replenishing glutathione and preventing liver damage. The other options are antidotes for different types of poisoning (e.g., Fomepizole for methanol or ethylene glycol poisoning).

Correct Answer: D

Rationale: The correct answer is D. A total weight gain of 15 lb in one year for a 2-year-old is excessive and may indicate an underlying issue such as a metabolic disorder or overfeeding. This rapid weight gain can put the child at risk for health problems. Choices A, B, and C are not typically concerning findings in a 2-year-old. A prominent abdomen can be normal at this age due to a toddler's slightly protruding belly, a forward curve of the spine at the sacral area is a typical finding in young children, and an increase in height of 5 inches in a year is within the expected range of growth for a 2-year-old.

Correct Answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

Correct Answer: C

Rationale: The correct answer is C: Airway obstruction. When planning nursing care for an infant with Meconium aspiration syndrome, a primary consideration for complications is the potential of airway obstruction. After the passage of meconium into the amniotic fluid, the infant may inhale or swallow the fluid, leading to meconium aspiration into the lower airways and causing a partial airway obstruction. This can result in respiratory distress and hypoxemia. Hypoglycemia (choice A) is a metabolic condition unrelated to meconium aspiration. Bowel obstruction (choice B) with meconium may indicate other conditions like cystic fibrosis or Hirschsprung disease, not directly related to meconium aspiration syndrome. Carbon dioxide retention (choice D) is not a primary consideration in meconium aspiration syndrome; instead, the focus is on addressing the airway obstruction and potential respiratory compromise.
