, Sentinel U APS Pediatric Typical Dari Moore | 100% Score
Activity Report | Latest Update .
This comprehensive practice exam is based on the Sentinel U Advanced Practice Series
(Pediatric Typical) virtual simulation featuring the patient Dari Moore. The questions are
organized by the nine clinical domains covered in the case: Growth & Developmental
Milestones, Well-Child Care & Health Promotion, Immunizations & Infectious Diseases,
Respiratory Disorders, Cardiovascular & Hematologic Disorders, Gastrointestinal & Nutritional
Disorders, Neurologic & Musculoskeletal Disorders, Dermatologic & Allergic Disorders, and
Pediatric Pharmacology & Emergency Management. Each question includes multiple-choice
options, the correct answer, and a detailed clinical rationale.
Domain I: Growth & Developmental Milestones (Questions 1–15)
Question 1: A 4-month-old infant is brought in for a well-child visit. Which fine motor skill should
the clinician expect to observe in a typically developing infant of this age?
A. Pincer grasp
B. Bringing hands to midline
C. Transferring objects from hand to hand
D. Stacking two blocks
CorreCt Answer: B. Bringing hands to midline.
rAtionAle: Bringing hands to the midline and bringing objects to the mouth are hallmark fine
motor milestones for a 4-month-old. The pincer grasp develops around 9 months, transferring
objects occurs around 6 months, and stacking blocks is expected later .
Question 2: At what age does the Moro (startle) reflex typically disappear in a healthy infant?
A. 1 month
B. 4 months
C. 9 months
D. 12 months
CorreCt Answer: B. 4 months.
rAtionAle: The Moro reflex is a primitive reflex that normally disappears by 4 to 6 months of
age as the infant's neurological system matures. Persistence beyond 6 months may indicate
underlying neurological dysfunction .
, Question 3: A 9-month-old infant presents for a well-child visit. Which gross motor milestone
should be expected at this age?
A. Sitting without support
B. Crawling
C. Walking independently
D. Pulling to stand
CorreCt Answer: D. Pulling to stand.
rAtionAle: By 9 months, most infants can pull to stand and may begin cruising along
furniture. Sitting without support is expected by 6–7 months, crawling by 7–10 months, and
walking independently typically occurs around 12–15 months .
Question 4: At what age does an infant typically develop the ability to sit without support?
A. 4 months
B. 6 months
C. 8 months
D. 10 months
CorreCt Answer: B. 6 months.
rAtionAle: Most infants can sit without support by approximately 6 months of age. This is a
key gross motor milestone that precedes crawling and pulling to stand .
Question 5: A 3-year-old child speaks in 4- to 5-word sentences and frequently asks "why"
questions. This language development is:
A. Advanced for a 3-year-old
B. Typical for a 3-year-old
C. Delayed for a 3-year-old
D. Only expected in 5-year-olds
CorreCt Answer: B. Typical for a 3-year-old.
rAtionAle: By age 3, children typically speak in 3- to 5-word sentences and begin asking
"why" questions as their cognitive and language skills expand. This represents typical language
development for this age .
Question 6: At what age does an infant typically develop social smiling?
A. Birth
B. 2 weeks
C. 2 months
D. 4 months
