Question 1
A 4-month-old infant is brought to the clinic for a well-child visit. Which
growth parameter is most appropriate for assessing nutritional status in
this age group?
• A) Body mass index (BMI)
• B) Weight-for-age percentile
• C) Head circumference percentile
• D) Mid-upper arm circumference
Correct ,,,,Answer,,,,: B
Rationale: Weight-for-age percentile is the primary indicator of nutritional
status in infants under 2 years because BMI is not reliable until the child is
older, and head circumference reflects brain growth rather than
nutritional status .
Question 2
A 3-year-old child is being evaluated for developmental milestones.
,Which standardized tool is most appropriate for assessing gross motor
skills at this age?
• A) Denver Developmental Screening Test II
• B) Peabody Developmental Motor Scales
• C) Bayley Scales of Infant Development
• D) Ages and Stages Questionnaire
Correct ,,,,Answer,,,,: B
Rationale: The Peabody Developmental Motor Scales specifically assess
fine and gross motor development in children from birth to 5 years,
making it ideal for a 3-year-old's gross motor evaluation .
Question 3
When reviewing a laboratory report, the nurse notes a serum potassium of
2.8 mEq/L in a 10-year-old receiving diuretic therapy for hypertension.
Which action should be taken first?
• A) Notify the physician immediately
• B) Administer a potassium-rich snack
• C) Document the value in the chart
• D) Repeat the laboratory test
Correct ,,,,Answer,,,,: A
Rationale: A potassium level of 2.8 mEq/L is critically low and can cause
cardiac arrhythmias; the nurse must promptly notify the prescriber for
urgent intervention . Normal pediatric potassium range is 3.5–5.0 mEq/L.
,Question 4
During a pediatric assessment, the nurse observes a 2-year-old child with
a rash on the cheeks, fever, and conjunctivitis. Which diagnosis is most
likely?
• A) Measles (rubeola)
• B) Rubella (German measles)
• C) Fifth disease (erythema infectiosum)
• D) Scarlet fever
Correct ,,,,Answer,,,,: C
Rationale: Fifth disease (parvovirus B19) presents with "slapped cheek"
rash, fever, and conjunctivitis. Measles presents with Koplik spots; rubella
has postauricular lymphadenopathy; scarlet fever presents with
sandpaper-like rash.
Question 5
A 2-week-old infant presents with projectile vomiting after feeds. The
nurse palpates an olive-shaped mass in the right upper quadrant. What
condition does the nurse suspect?
• A) Gastroesophageal reflux disease
• B) Pyloric stenosis
• C) Intussusception
• D) Malrotation with volvulus
Correct ,,,,Answer,,,,: B
Rationale: Projectile vomiting with palpable olive-shaped mass in the
right upper quadrant is classic for hypertrophic pyloric stenosis, typically
, presenting at 2–8 weeks of age. The olive sign represents the
hypertrophied pyloric muscle.
Question 6
The nurse is assessing a 6-month-old infant. Which developmental
milestone is expected at this age?
• A) Walking independently
• B) Sitting without support
• C) Using two-word phrases
• D) Rolling from back to front only
Correct ,,,,Answer,,,,: B
Rationale: At 6 months, infants typically can sit without support . Walking
independently occurs around 12 months. Two-word phrases occur
around 24 months. Rolling both directions occurs earlier at 4–5 months.
Question 7
A 7-year-old child with asthma presents with wheezing and a respiratory
rate of 32 breaths/min. Which finding most strongly indicates impending
respiratory failure?
• A) Use of accessory muscles
• B) Nasal flaring
• C) Decreased breath sounds bilaterally
• D) SpO₂ of 94% on room air
