A nurse is assessing a 5-month-old infant. Which of the following findings should the nurse report to the provider?

A. Unable to roll from back to abdomen. Incorrect. Many infants do not roll over until closer to 6 months old, so this is not a concerning finding at 5 months.B. Absent grasp reflex. Incorrect. The grasp reflex typically disappears around 4 to 6 months of age, so its absence is normal at this stage.C. Unable to hold a bottle. Incorrect. Holding a bottle can vary widely, and many 5-month-olds do not yet have this skill.D. Exhibits head lag when pulled to a sitting position. Correct. By 5 months, most infants should have sufficient neck muscle control to not exhibit head lag. Persistent head lag could indicate a developmental delay or neurological problem.
