Nurse 2026/2027 Questions And Answers
Q1. Which approach is most appropriate when evaluating a child's
growth over time?
A) Compare weight with one population average at a single visit
B) Evaluate height without considering age or sex
C) Use adult BMI thresholds beginning in infancy
D) Plot serial measurements on an age- and sex-appropriate growth chart
and evaluate the growth trajectory
Correct Answer: D) Plot serial measurements on an age- and sex-appropriate
growth chart and evaluate the growth trajectory
Rationale: Serial measurements reveal whether a child is following an
expected growth pattern. Trends and growth velocity are generally more
informative than an isolated percentile.
Q2. Which finding during a well-child visit most strongly suggests
that further developmental evaluation is needed?
A) Loss of previously acquired developmental skills
B) Temporary stranger anxiety in infancy
C) Preference for parallel play during toddlerhood
D) Variable appetite during early childhood
Correct Answer: A) Loss of previously acquired developmental skills
Rationale: Developmental regression is abnormal and may indicate
neurologic, metabolic, genetic, or other significant disease requiring prompt
evaluation.
Q3. At which ages is standardized general developmental screening
routinely emphasized during early childhood preventive care?
A) 2, 4, and 6 months
B) 12, 24, and 36 months only
C) 6, 12, and 24 months
D) Approximately 9, 18, and 30 months
Correct Answer: D) Approximately 9, 18, and 30 months
Rationale: Standardized developmental screening at key early-childhood
visits helps identify developmental concerns that may not be evident through
surveillance alone.
,Q4. At which ages is autism-specific developmental screening
routinely recommended during early childhood?
A) 6 and 12 months
B) 9 and 30 months
C) 18 and 24 months
D) 3 and 4 years
Correct Answer: C) 18 and 24 months
Rationale: Autism-specific screening during the second year of life
facilitates earlier identification and access to developmental services.
Q5. Which measurement is routinely used to classify weight status
beginning at approximately 2 years of age?
A) Weight-for-length alone
B) Head circumference
C) Chest circumference
D) Body mass index-for-age percentile
Correct Answer: D) Body mass index-for-age percentile
Rationale: BMI-for-age percentile is used after age 2 to evaluate
underweight, healthy weight, overweight, and obesity in the context of age
and sex.
Q6. In a healthy child without special risk factors, routine blood-
pressure measurement generally begins at what age?
A) Birth
B) 12 months
C) 3 years
D) 10 years
Correct Answer: C) 3 years
Rationale: Routine blood-pressure screening begins in early childhood, with
earlier or more frequent measurement when conditions associated with
hypertension are present.
Q7. Which recommendation best promotes preventive oral health in
infancy?
A) Wait until all primary teeth erupt before dental care begins.
B) Establish a dental home by approximately 1 year of age.
, C) Avoid brushing until a child can spit toothpaste out independently.
D) Use a full toothbrush-length amount of fluoride toothpaste in infancy.
Correct Answer: B) Establish a dental home by approximately 1 year of age.
Rationale: Early preventive dental care helps establish healthy oral habits,
assess caries risk, and identify dental problems before extensive disease
develops.
Q8. Which sleep recommendation is most appropriate for a healthy
infant?
A) Place the infant supine for every sleep on a firm, flat sleep surface.
B) Use prone positioning after feeding to prevent aspiration.
C) Place soft blankets around the infant to maintain body temperature.
D) Use an inclined sleep surface for routine sleep.
Correct Answer: A) Place the infant supine for every sleep on a firm, flat
sleep surface.
Rationale: Supine sleep on a firm, flat surface reduces the risk of sleep-
related infant death. Loose bedding and soft objects should be avoided.
Q9. When should complementary foods generally be introduced to a
healthy infant?
A) At 2 months regardless of development
B) Around 6 months when developmentally ready
C) After 12 months
D) Only after all primary teeth erupt
Correct Answer: B) Around 6 months when developmentally ready
Rationale: Complementary foods are generally introduced around 6 months
when the infant has sufficient head control, oral-motor readiness, and
interest in food.
Q10. Routine screening for iron-deficiency anemia is commonly
performed at approximately what age?
A) Birth only
B) 2 months
C) 5 years
D) 12 months
Correct Answer: D) 12 months
