Rationale: By 6 months, infants typically sit without support, a key gross motor milestone.
Walking independently occurs around 12 months, pincer grasp develops around 9–12 months,
and two-word phrases emerge around 2 years, per ATI pediatric developmental standard s.
Question 2
A nurse is caring for a 4-year-old child with suspected appendicitis. Which symptom is most
concerning?
A. Low-grade fever
B. Right lower quadrant pain
C. Mild nausea
D. Increased appetite

A. Give large volumes at once
B. Administer small, frequent sips
C. Mix with juice for taste
D. Avoid giving fluids for 4 hours
Correct Answer: B. Administer small, frequent sips
Rationale: Small, frequent sips of oral rehydration solution prevent worsening dehydration and

standards.
Question 4
A nurse is assessing a newborn with suspected jaundice. Which finding requires immediate
intervention?
A. Yellowing of the sclera
B. Breastfeeding frequently
C. Sleeping for 3 hours
D. Passing meconium
Correct Answer: A. Yellowing of the sclera

A nurse is preparing to administer a measles, mumps, and rubella (MMR) vaccine to a 15-
month-old. Which site is most appropriate?
A. Deltoid muscle
