A nurse in a provider's office is preparing to administer immunizations to a 12- year-old client during a well-child visit.
Which of the following immunizations should the nurse plan to administer?

The correct answer is d. Exhibits head lag when pulled to a sitting position.

Choice A: Unable to hold a bottle At around 6 months of age, some babies can hold their own bottle. This is not a concerning finding for a 5-month-old infant. Therefore, this is not the correct answer.

Choice B: Unable to roll from back to abdomen Rolling over often starts around 4-6 months, so it’s not unusual for a 5-month-old to still be developing this skill. Therefore, this is not the correct answer.

Choice C: Absent grasp reflex The grasp reflex is an involuntary movement that your baby starts making in utero and continues doing until around 6 months of age. The grasp reflex lasts until the baby is about 5 to 6 months old. Therefore, this is not the correct answer.

Choice D: Exhibits head lag when pulled to a sitting position By the age of 5 months, most infants have developed enough strength in their neck and upper body to control their head movement. This means they should not exhibit a significant head lag when pulled to a sitting position1. If this is not the case, it could indicate a delay in motor development or a potential neurological issue, which should be reported to the healthcare provider for further evaluation. Therefore, this is the correct answer.

Bruises in areas of the body not typically injured by accident or normal childhood activities can be a potential indicator of physical abuse.

Choice A is wrong because Weight in 45th percentile is not an answer because it falls within the normal range for weight.

Choice B is wrong because Abrasions on the knees are not an answer because they are a common injury in children and can occur during normal play.

Choice D is wrong because Front deciduous teeth missing is not an answer because it is normal for children to lose their deciduous teeth.
