As the nurse caring for an infant who has been prescribed Amoxicillin (Amoxil) orally every 6 hours, you need to calculate the dose.

The recommended dosage is 50 mg/kg/day, divided into multiple doses.

If the infant weighs 6 kg, how much Amoxicillin should you administer per dose?

Step 1 is (50 mg × 6 kg) ÷ 24 hours. The total daily dose calculates to 300 mg/day.

Step 2 is 300 mg ÷ 4 doses/day. Each dose calculates to 75 mg of Amoxicillin.

Final calculated dose per administration is 75 mg.

Choice A rationale

Performing a sharp hand clap near the infant activates the Moro reflex, a startle response present at birth that integrates by around six months of age. The reflex involves symmetric extension and abduction of the arms followed by flexion, demonstrating proper neurological function.

Choice B rationale

Placing a finger at the base of the newborn's toes elicits the plantar grasp reflex, not the Moro reflex. This reflex involves flexion of the toes when pressure is applied to the sole and is unrelated to startling the infant.

Choice C rationale

Holding the newborn vertically allowing one foot to touch the table surface elicits the stepping reflex, not the Moro reflex. This reflex involves simulated walking movements and is unrelated to assessing startle responses.

Choice D rationale

Turning the newborn's head quickly to one side elicits the tonic neck reflex (fencing reflex) rather than the Moro reflex. This reflex involves extension of the limbs on the side the head is turned and flexion on the opposite side. .
