A nurse is assisting with the admission of a child who has pertussis. Which of the following actions should the nurse take?

A. Rotavirus: The rotavirus vaccine is recommended for infants at 2, 4, and possibly 6 months of age, depending on the vaccine formulation. It helps protect against rotavirus, which can cause severe diarrhea and dehydration in infants.

B. Measles, mumps, rubella (MMR): The MMR vaccine is not given until 12-15 months of age. It is not part of the vaccination schedule for a 4-month-old infant.

C. Varicella (VAR): The varicella vaccine is typically administered at 12-15 months of age. It is not appropriate for a 4-month-old infant.

D. Influenza: The influenza vaccine is recommended annually starting at 6 months of age. A 4-month-old is too young to receive the influenza vaccine.

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.
