The nurse is assessing a 6-month-old infant. Which response requires further evaluation by the nurse?
Has doubled birth weight.
Plays "peek-a-boo."
Demonstrates startle reflex.
Turns head to locate sound.
The Correct Answer is C
The startle reflex, also known as the Moro reflex, is a normal reflex in infants that is present at birth and usually disappears by 3-4 months of age. The reflex is elicited by a sudden loud noise or change in position, and the infant will extend their arms and legs, then bring them back in towards their body.
If a 6-month-old infant is still demonstrating the startle reflex, it may indicate a developmental delay or neurological issue and requires further evaluation by the nurse or healthcare provider.
The other responses are all normal developmental milestones for a 6-month-old infant. By 6 months of age, most infants will have doubled their birth weight, enjoy playing games like peek-a-boo, and have developed the ability to turn their head to locate sounds.

Correct Answer is ["1.3"]
Explanation
1.3 mL of amoxicillin suspension with each dose.
To calculate the correct dose of amoxicillin to give to the child, follow these steps:
Step 1: Convert the child's weight from pounds to kilograms. 18 pounds ÷ 2.2 = 8.18 kilograms
Step 2: Calculate the total daily dose of amoxicillin. 25 mg/kg/day x 8.18 kg = 204.5 mg/day
Step 3: Divide the total daily dose into two equal doses to be given every 12 hours. 204.5 mg/day ÷ 2 doses = 102.25 mg/dose
Step 4: Determine how many mL of the suspension contain 102.25 mg of amoxicillin. 400 mg/5 mL = 80 mg/mL 102.25 mg ÷ 80 mg/mL = 1.28 mL

Correct Answer is D
Explanation
The nurse should implement the intervention of including the child's toy in the collection of information when the child screams and tries to hide behind the parent, dropping a stuffed toy. This can help engage the child and make them feel more comfortable during the medical history collection process. The other options (A, B, and C) are not appropriate interventions in this situation.
