Which immunization should be considered carefully before being given to a child receiving chemotherapy for cancer?

A. Recommending a significant increase in caloric intake is incorrect because forced or excessive caloric intake can lead to unhealthy weight gain and does not appropriately address normal developmental growth patterns. Preschool growth slows naturally compared to infancy, and nutritional changes should only be made if growth is outside expected ranges.

B. Advising that a child’s growth should exactly match peers is incorrect because normal growth varies among children. Genetics, body type, and overall health influence growth, and children do not grow at identical rates. Comparing strictly to peers can cause unnecessary anxiety for parents.

C. Suggesting delaying further growth assessments is incorrect because regular monitoring of growth is essential during all developmental stages. Preschool growth patterns are well understood and can be accurately evaluated using standardized growth charts.

D. Explaining that preschool growth is typically steady but slower compared to infancy is correct because preschool-aged children usually gain about 4 to 5 pounds and grow 2 to 3 inches per year. The child’s growth of 2.5 inches and 5 pounds falls squarely within expected norms, making this a reassuring and educational response that supports parental understanding.

A. The development of pubic hair is incorrect as the first sign of puberty in most females. Pubic hair usually appears after the onset of breast development and is part of adrenarche, which occurs later in puberty.

B. Breast development is correct. The initial sign of female puberty is thelarche, or the development of breast buds, typically occurring between 8 and 13 years of age. Breast development signals the beginning of gonadarche, the activation of the hypothalamic-pituitary-ovarian axis.

C. The onset of menstruation is incorrect because menarche usually occurs 2–2.5 years after breast development. Menarche indicates more advanced pubertal development rather than the first sign.

D. The growth spurt is incorrect because although girls experience a rapid increase in height during puberty, the growth spurt usually occurs after breast budding begins, not before.
