A nurse is caring for a 6-month-old child. The child's provider has ordered a diphtheria, tetanus, and pertussis (DTaP) vaccine to be administered. Which of the following should cause the nurse to question the administration of this vaccine?

A. "I will provide low-fat meals for my child.": Children with cystic fibrosis need a high-calorie, high-fat diet to meet their increased energy needs and to help with growth and development due to malabsorption issues.

B. "I will restrict the amount of salt in my child's meals.": Children with cystic fibrosis tend to lose more salt through sweat and often require additional salt in their diet.

C. "I will put my child in daycare to ensure that she socializes with other children.": While socialization is important, children with cystic fibrosis are at higher risk for respiratory infections and should avoid environments where they are more likely to be exposed to pathogens.

D. "I will make sure my child washes her hands before eating.": Hand hygiene is crucial for preventing infections, which are a significant risk for children with cystic fibrosis due to their compromised lung function.

A. "He takes his medication between meals with water." Taking carbamazepine with food helps reduce gastrointestinal upset, but taking it between meals is not critical unless there are specific issues. This is not a priority unless the patient is experiencing significant GI discomfort.

B. "He only sleeps about 5 hours each night." Insufficient sleep can exacerbate seizure disorders, but it is not directly life-threatening. Improving sleep hygiene is important but not the most immediate concern compared to other symptoms.

C. "He seems to be getting a lot more bumps and bruises lately." Increased bruising can indicate thrombocytopenia, a potential side effect of carbamazepine, which can lead to serious bleeding issues. This is the priority as it may indicate a severe adverse effect requiring immediate medical attention and possible adjustment of medication.

D. "He has not been eating as much lately." Decreased appetite can be a side effect of many medications, including carbamazepine, but it is generally not immediately dangerous unless it leads to significant weight loss or nutritional deficiencies. It’s important but not the most urgent concern.
