A nurse is evaluating a 4-year-old child who has cystic fibrosis and has been receiving chest physiotherapy treatments.
The nurse should identify which of the following findings as an indication that the therapy has been effective?

This helps to keep the urine collection bag in place while the infant is active.

Choice A is wrong because the opening of the bag should be positioned over the urethra only, not over both the urethra and anus.

Choice C is wrong because there is no need to apply lidocaine gel to the perineum before attaching the bag.

Choice D is wrong because there is no need to stretch the perineum taut when applying the bag.

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.
