A nurse is caring for an infant who has coarctation of the aorta. Which of the following should the nurse identify as an expected finding?

A. Fasting blood glucose 100 mg/dL: This level is within the normal range and does not contraindicate the use of clozapine. Monitoring blood glucose is important due to the risk of metabolic syndrome, but a normal level is not a concern.

B. Hgb 14 g/dL: Hemoglobin levels in this range are normal and indicate adequate oxygen-carrying capacity. This finding does not contraindicate the use of clozapine.

C. Heart rate 58/min: A heart rate of 58 beats per minute is considered bradycardic but does not directly contraindicate the use of clozapine. Monitoring cardiovascular health is important, but this alone is not a reason to withhold the medication.

D. WBC count 2,900/mm³: This finding is significant because clozapine can cause agranulocytosis, a potentially life-threatening decrease in white blood cells. A WBC count below 3,000/mm³ is a contraindication for clozapine administration, as it increases the risk of infection and other complications. Therefore, this finding indicates that clozapine should not be administered.

A) Playing with an imaginary friend: While imaginative play does begin to develop in toddlers, having an imaginary friend is more typical in older preschool-aged children, around 3 to 4 years old. Therefore, this activity may not be expected in a 30-month-old child.

B) Playing with a large plastic truck: At 30 months old, children are typically engaged in parallel play and are interested in toys that promote gross motor skills and imaginative play. Playing with a large plastic truck is developmentally appropriate, as children at this age enjoy manipulating vehicles and may engage in simple pretend play related to driving or racing.

C) Playing with dress-up clothes: Although some children may enjoy dress-up, this activity tends to be more prominent in slightly older toddlers and preschoolers. A 30-month-old may show interest in dressing up but may not engage in it as frequently or with as much understanding of role play as older children.

D) Playing with a jump rope: Jump rope activities require a level of coordination and motor skills that are typically beyond what a 30-month-old child can achieve. At this age, children are still developing basic motor skills and would not yet be proficient in using a jump rope effectively.
