Question 1: A nurse is assessing a 6-month-old infant during a well-child visit. Which
developmental milestone should the nurse expect the infant to demonstrate?
A. Sitting without support
B. Transferring objects from hand to hand
C. Walking with one hand held
D. Using a pincer grasp
CORRECT ANSWER: B. Transferring objects from hand to hand
Rationale: At 6 months of age, infants typically develop the ability to transfer objects from one
hand to the other, which reflects developing hand-eye coordination and fine motor skills.
Sitting without support typically emerges around 8 months, walking with assistance occurs
around 9-12 months, and the pincer grasp develops around 9-10 months. This milestone
assessment aligns with expected developmental progression per pediatric nursing standards.
Question 2: A pediatric nurse is preparing to administer an immunization to a 2-month-old
infant. Which vaccine is routinely scheduled for administration at this age according to the
CDC immunization schedule?
A. Measles, mumps, and rubella (MMR)
B. Varicella
C. Diphtheria, tetanus, and acellular pertussis (DTaP)
D. Human papillomavirus (HPV)
CORRECT ANSWER: C. Diphtheria, tetanus, and acellular pertussis (DTaP)
Rationale: The DTaP vaccine is routinely administered at 2, 4, and 6 months of age as part of
the primary immunization series. MMR and varicella vaccines are typically given at 12-15
months, while HPV vaccine is initiated at age 11-12 years. Administering age-appropriate
immunizations is critical for preventing vaccine-preventable diseases in pediatric populations.
Question 3: A nurse is caring for a 4-year-old child who is scheduled for a surgical procedure.
Which pain assessment tool is most appropriate for this child?
A. FLACC scale
B. Faces Pain Scale-Revised
C. Numeric Rating Scale
D. CRIES scale
CORRECT ANSWER: B. Faces Pain Scale-Revised
Rationale: The Faces Pain Scale-Revised is appropriate for children ages 3 years and older who
can self-report pain by selecting a facial expression that matches their pain level. The FLACC
scale is used for children 2 months to 7 years who cannot self-report, the Numeric Rating Scale
is for children 5 years and older with cognitive ability to understand numbers, and the CRIES
scale is designed for neonates. Selecting age-appropriate pain assessment tools ensures
accurate pain evaluation and management.
Question 4: A nurse is teaching a parent about fever management for their 18-month-old
child. Which statement by the parent indicates understanding of the teaching?
,A. "I will give my child aspirin if the fever is above 101°F."
B. "I should bundle my child in heavy blankets to help reduce the fever."
C. "I can use acetaminophen or ibuprofen based on my child's weight."
D. "I will alternate acetaminophen and ibuprofen every hour."
CORRECT ANSWER: C. I can use acetaminophen or ibuprofen based on my child's weight.
Rationale: Antipyretic medications for pediatric patients should be dosed according to weight,
not age, to ensure safety and efficacy. Aspirin is contraindicated in children due to the risk of
Reye syndrome. Bundling a febrile child can trap heat and worsen fever. Alternating
antipyretics every hour is not recommended due to risk of medication errors and toxicity.
Weight-based dosing is a fundamental principle of pediatric pharmacology.
Question 5: A nurse is assessing a toddler in the emergency department who has been
diagnosed with bronchiolitis. Which finding should the nurse recognize as a priority requiring
immediate intervention?
A. Respiratory rate of 45 breaths per minute
B. Oxygen saturation of 91% on room air
C. Mild nasal congestion
D. Decreased oral intake
CORRECT ANSWER: B. Oxygen saturation of 91% on room air
Rationale: An oxygen saturation below 92-94% in a child with bronchiolitis indicates hypoxemia
and requires immediate intervention such as supplemental oxygen. While tachypnea, nasal
congestion, and decreased oral intake are common findings in bronchiolitis, hypoxemia poses
the greatest risk for respiratory failure and must be addressed promptly to prevent
deterioration.
Question 6: A pediatric nurse is planning care for a school-age child with type 1 diabetes
mellitus. Which intervention should the nurse prioritize to promote self-management?
A. Administering all insulin doses for the child
B. Teaching the child to recognize signs of hypoglycemia
C. Restricting the child's participation in physical activities
D. Providing all meals through a supervised hospital cafeteria
CORRECT ANSWER: B. Teaching the child to recognize signs of hypoglycemia
Rationale: School-age children are developing autonomy and can begin learning self-
management skills for chronic conditions. Teaching recognition of hypoglycemia symptoms
(shakiness, sweating, confusion) empowers the child to participate in their care and respond
appropriately. Complete dependence on nurses for insulin administration, activity restriction,
or meal supervision does not foster developmental progression or long-term disease
management.
Question 7: A nurse is caring for an infant with gastroesophageal reflux disease (GERD).
Which positioning intervention should the nurse implement after feedings?
A. Place the infant in a supine position
B. Place the infant in a prone position
C. Hold the infant upright for 20-30 minutes
D. Place the infant in a Trendelenburg position
,CORRECT ANSWER: C. Hold the infant upright for 20-30 minutes
Rationale: Keeping an infant with GERD upright after feedings utilizes gravity to reduce reflux
episodes and aspiration risk. The supine position is recommended for safe sleep but may
worsen reflux symptoms immediately after feeding. Prone positioning is contraindicated for
infant sleep due to SIDS risk. Trendelenburg positioning is not indicated for GERD management
and may increase intracranial pressure.
Question 8: A nurse is assessing a 9-month-old infant and notes the presence of a Moro
reflex. Which action should the nurse take?
A. Document the finding as normal for this age
B. Notify the provider immediately
C. Perform a neurological assessment
D. Reassess the reflex in 1 hour
CORRECT ANSWER: B. Notify the provider immediately
Rationale: The Moro reflex typically disappears by 4-6 months of age. Persistence of primitive
reflexes beyond expected developmental timelines may indicate neurological abnormalities
such as cerebral palsy or developmental delay. While further neurological assessment may be
warranted, the priority is to notify the provider for evaluation and potential diagnostic testing.
Question 9: A pediatric nurse is preparing to administer medication to a 3-year-old child.
Which strategy is most effective for promoting cooperation?
A. Restrain the child quickly to administer the medication
B. Offer the child a choice between two acceptable options
C. Tell the child the medication will not taste bad
D. Administer the medication while the child is sleeping
CORRECT ANSWER: B. Offer the child a choice between two acceptable options
Rationale: Offering limited choices (e.g., "Do you want to take your medicine with apple juice or
water?") provides toddlers with a sense of control and autonomy, which aligns with Erikson's
stage of autonomy versus shame and doubt. Restraint should be a last resort, dishonesty about
taste erodes trust, and administering medication during sleep is unsafe and ineffective for
teaching cooperation.
Question 10: A nurse is caring for a child with suspected appendicitis. Which assessment
finding is most indicative of this condition?
A. Generalized abdominal pain that migrates to the right lower quadrant
B. Diarrhea with mucus
C. Pain that improves with movement
D. Hyperactive bowel sounds in all quadrants
CORRECT ANSWER: A. Generalized abdominal pain that migrates to the right lower quadrant
Rationale: Classic appendicitis presentation includes periumbilical pain that migrates to
McBurney's point (right lower quadrant) over 12-24 hours. Diarrhea is more characteristic of
gastroenteritis. Pain with appendicitis typically worsens with movement, and bowel sounds
may be hypoactive or absent due to peritoneal irritation. Recognizing classic symptom patterns
facilitates timely diagnosis and intervention.
, Question 11: A nurse is teaching parents about car seat safety for their newborn. Which
statement indicates the parents understand the teaching?
A. "We will place the car seat in the front passenger seat with the airbag on."
B. "We will use a rear-facing car seat until our child is 2 years old."
C. "We can transition to a forward-facing seat when our child weighs 20 pounds."
D. "We will place thick blankets under the harness for warmth."
CORRECT ANSWER: B. We will use a rear-facing car seat until our child is 2 years old.
Rationale: Current AAP guidelines recommend rear-facing car seats until at least age 2 years or
until the child reaches the highest weight or height allowed by the car seat manufacturer. Front
seat placement with active airbags is dangerous for infants. Weight alone is not the sole
criterion for transitioning seats. Thick blankets under harnesses compromise safety by creating
slack; blankets should be placed over the secured harness.
Question 12: A pediatric nurse is caring for a child with sickle cell disease experiencing a vaso-
occlusive crisis. Which intervention should the nurse prioritize?
A. Administering opioid analgesics for pain management
B. Applying cold compresses to affected joints
C. Restricting oral fluid intake
D. Encouraging ambulation to promote circulation
CORRECT ANSWER: A. Administering opioid analgesics for pain management
Rationale: Pain management is the priority intervention during a vaso-occlusive crisis, as severe
pain results from tissue ischemia due to sickled erythrocytes obstructing blood flow. Cold
compresses can cause vasoconstriction and worsen sickling. Adequate hydration (not
restriction) helps reduce blood viscosity. Rest is recommended during acute crisis; ambulation
may increase pain and oxygen demand.
Question 13: A nurse is assessing a 2-year-old child's growth parameters. Which finding
should the nurse report to the provider?
A. Weight at the 50th percentile
B. Height at the 25th percentile
C. Head circumference crossing two percentile lines downward
D. Weight and height proportional on growth chart
CORRECT ANSWER: C. Head circumference crossing two percentile lines downward
Rationale: Crossing two or more percentile lines on growth charts, particularly for head
circumference in toddlers, may indicate abnormal brain growth, malnutrition, or underlying
pathology and warrants further evaluation. Consistent percentiles for weight and height, even
if not at the 50th percentile, typically represent normal growth patterns when proportional.
Question 14: A nurse is preparing to perform a physical assessment on a preschool-age child.
Which approach is most appropriate?
A. Begin with invasive procedures to get them over with first
B. Allow the child to handle assessment equipment before use
C. Perform the assessment with the parent out of the room
D. Use medical terminology to explain each step
CORRECT ANSWER: B. Allow the child to handle assessment equipment before use
