A nurse is preparing to administer amoxicillin 80 mg/kg/day divided into two doses daily to a 2-year-old client who weighs 10 kg (22 lb). Available is amoxicillin suspension 400 mg/5 mL. How many mL of amoxicillin should the nurse administer per dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A Reason:

Shrug their shoulders against mild pressure. The accessory nerve controls the movement of the trapezius and sternocleidomastoid muscles. To assess this nerve, the nurse should ask the child to shrug their shoulders against mild resistance or pressure applied by the nurse's hands on the child's shoulders. This action assesses the strength and symmetry of the trapezius muscles.

Choice B Reason:

Move their tongue in all directions. This action assesses the function of the hypoglossal nerve (cranial nerve XII), which controls tongue movement.

Choice C Reason:

Follow a light in the six cardinal positions. This action assesses the function of the extraocular muscles and cranial nerves III, IV, and VI, which control eye movements.

Choice D Reason:

Show their teeth while smiling. This action primarily assesses the facial nerve (cranial nerve VII), which controls facial expressions, including smiling and showing teeth.

Choice A Reason:

Exhibits head lag when pulled to a sitting position is correct. At 5 months old, infants typically show improvement in head control, and head lag (where the infant's head falls back when pulled to a sitting position) should be diminishing. Persistent head lag might indicate potential developmental concerns or issues with muscle tone that warrant further evaluation by the healthcare provider.

Choice B Reason:

Unable to hold a bottle is incorrect. At 5 months old, some infants might not have developed the ability to hold a bottle independently yet. This skill can vary among infants and might not be a significant concern at this stage.

Choice C Reason:

Unable to roll from back to abdomen is incorrect. Rolling from back to abdomen might not be fully developed in all infants at 5 months old. It's a milestone that some infants achieve later within the 5 to 6-month range, so it might not be an immediate concern unless it persists significantly beyond that range.

Choice D Reason:

Absent grasp reflex is incorrect. By 5 months old, the typical infant's grasp reflex usually starts to diminish as voluntary grasping begins to develop. However, the absence of the grasp reflex might not be an immediate concern unless it's accompanied by other signs of developmental delay or regression.
