Correct Answer: C

Rationale: The correct answer is C. Needing assistance to climb stairs is considered expected behavior for an 18-month-old toddler. At this age, children are still developing their gross motor skills, coordination, and balance, which can vary in proficiency. It is common for toddlers to be able to crawl upstairs before mastering the skill of climbing stairs upright. Options A, B, and D are incorrect because at 18 months, it is normal for children to require help and practice with climbing stairs and does not necessarily point to any specific medical conditions or developmental issues.

Correct Answer: A

Rationale: Placing the infant on their back to sleep is the correct recommendation to reduce the risk of sudden infant death syndrome (SIDS). This sleep position has been shown to significantly decrease the incidence of SIDS. Using a pacifier during sleep (Choice B) can also help reduce the risk, but it is secondary to the back sleeping position. Having the infant sleep on their side (Choice C) is not recommended, as it increases the risk of SIDS. Keeping the infant's room cool (Choice D) may provide a comfortable sleeping environment but does not directly reduce the risk of SIDS.

Correct Answer: B

Rationale: Colicky behavior in infants is primarily characterized by paroxysmal abdominal pain, resulting in excessive crying and fussiness. The pain episodes are often unpredictable and can be distressing for both the infant and the parents. Inadequate peristalsis (Choice A) refers to weak or ineffective bowel movements and is not the typical cause of colic. While some infants may experience colic due to an allergic response to certain proteins in milk (Choice C), this is not the primary cause of colic behavior in all infants. Choice D, a protective mechanism designed to eliminate foreign proteins, is not a recognized cause of colic. Therefore, the correct explanation for the cause of colicky behavior in infants is paroxysmal abdominal pain.

Correct Answer: B

Rationale: The correct answer is B: 'Long-lasting active immunity is conferred.' Tetanus toxoid injection provides long-lasting active immunity by stimulating the body to produce its own antibodies. Choice A is incorrect because tetanus toxoid injection does not provide passive immunity. Choice C is incorrect because the immunity conferred by the vaccine is not natural but artificially induced. Choice D is incorrect as the immunity provided by the tetanus toxoid injection is active, not passive.

Correct Answer: B

Rationale: The correct answer is B. While special dietary needs may be important for a child with Down syndrome, they are typically not the primary concern for a 1-month-old. The nurse would be least likely to focus on this aspect as immediate issues such as monitoring for congenital heart defects (echocardiogram), cervical spine abnormalities (radiographs), and respiratory infections are more critical in the early months. Adhering to dietary needs is important, but it is usually addressed as the child grows older and is not the priority during the infant stage.
