Pediatrics Proctored Exam Success
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 one hand to the other
C. Walking with one hand held
D. Saying two meaningful words
CORRECT ANSWER: B. Transferring objects from one hand to the other
RATIONALE:At 6 months of age, infants typically develop the ability to transfer objects
from one hand to the other, demonstrating developing fine motor coordination. Sitting
without support typically occurs around 8 months, walking with assistance around 12
months, and saying meaningful words usually begins after 12 months. This milestone
assessment aligns with Denver II developmental screening expectations.
Question 2: A pediatric nurse is preparing to administer an immunization to a 2-
month-old infant. Which vaccine is typically administered at this age according to
the CDC recommended childhood immunization schedule?
A. Varicella vaccine
B. MMR vaccine
C. DTaP vaccine
D. HPV vaccine
CORRECT ANSWER: C. DTaP vaccine
RATIONALE:The DTaP (diphtheria, tetanus, and acellular pertussis) vaccine is routinely
administered at 2, 4, and 6 months of age. Varicella and MMR vaccines are first given at
12-15 months, while the HPV vaccine series begins at age 11-12 years. Following the
CDC schedule ensures optimal protection during vulnerable developmental periods.
Question 3: A nurse is caring for a 4-year-old child diagnosed with acute otitis
media. Which assessment finding should the nurse prioritize reporting to the
provider?
,A. Mild ear pain rated 3/10
B. Temperature of 38.1°C (100.6°F)
C. Bulging, erythematous tympanic membrane
D. Clear drainage from the ear canal
CORRECT ANSWER: D. Clear drainage from the ear canal
RATIONALE:Clear drainage from the ear canal may indicate tympanic membrane
perforation, which requires immediate provider evaluation to prevent complications
such as mastoiditis or hearing loss. While bulging tympanic membrane confirms otitis
media diagnosis, drainage suggests rupture needing specific management. Mild pain
and low-grade fever are expected findings in uncomplicated cases.
Question 4: A nurse is teaching parents about safe sleep practices for their
newborn. Which statement by the parents indicates understanding of the
teaching?
A. "We will place our baby on their side to sleep to prevent choking."
B. "We will use a soft mattress with loose bedding for comfort."
C. "We will place our baby on their back on a firm sleep surface."
D. "We will share our bed with the baby for easier nighttime feeding."
CORRECT ANSWER: C. "We will place our baby on their back on a firm sleep
surface."
RATIONALE:The American Academy of Pediatrics recommends placing infants on their
back on a firm sleep surface without loose bedding, pillows, or soft objects to reduce
Sudden Infant Death Syndrome (SIDS) risk. Side sleeping is unstable and increases
SIDS risk, soft surfaces pose suffocation hazards, and bed-sharing increases accidental
suffocation risk despite convenience for feeding.
Question 5: A nurse is calculating the dose of amoxicillin for a child weighing 22
pounds. The prescribed dose is 40 mg/kg/day divided every 8 hours. How many
milligrams should the nurse administer per dose? (Round to the nearest whole
number)
A. 133 mg
B. 267 mg
C. 400 mg
D. 800 mg
CORRECT ANSWER: A. 133 mg
RATIONALE:First convert pounds to kilograms: 22 lbs ÷ 2.2 = 10 kg. Calculate total daily
dose: 40 mg/kg × 10 kg = 400 mg/day. Divide by 3 doses (every 8 hours): 400 mg ÷ 3 =
133.3 mg, rounded to 133 mg per dose. Accurate weight-based calculations prevent
underdosing or toxicity in pediatric patients.
,Question 6: A nurse is assessing a toddler with suspected croup. Which
characteristic finding should the nurse expect?
A. High-pitched inspiratory stridor
B. Expiratory wheezing
C. Productive cough with yellow sputum
D. Grunting respirations
CORRECT ANSWER: A. High-pitched inspiratory stridor
RATIONALE:Croup (laryngotracheobronchitis) typically presents with a barking cough
and high-pitched inspiratory stridor due to subglottic inflammation and edema.
Expiratory wheezing suggests asthma or bronchiolitis, productive cough indicates
bacterial infection, and grunting is associated with severe respiratory distress or
pneumonia. Recognizing stridor guides appropriate humidified oxygen and
corticosteroid interventions.
Question 7: A nurse is caring for a school-age child with type 1 diabetes mellitus.
Which finding indicates the child is experiencing hypoglycemia?
A. Polyuria and polydipsia
B. Fruity breath odor
C. Diaphoresis and tremors
D. Kussmaul respirations
CORRECT ANSWER: C. Diaphoresis and tremors
RATIONALE:Hypoglycemia manifests with autonomic symptoms including diaphoresis,
tremors, tachycardia, and anxiety due to catecholamine release. Polyuria, polydipsia,
fruity breath, and Kussmaul respirations are signs of hyperglycemia and diabetic
ketoacidosis. Prompt recognition of hypoglycemia allows immediate carbohydrate
administration to prevent neurological compromise.
Question 8: A nurse is preparing to perform a physical assessment on a
preschooler. Which approach should the nurse use to minimize the child's anxiety?
A. Perform all invasive procedures first to get them over with
B. Allow the child to handle examination equipment before use
C. Speak only to the parents while ignoring the child
D. Restrain the child quickly to complete the assessment
CORRECT ANSWER: B. Allow the child to handle examination equipment before use
RATIONALE:Preschoolers benefit from play therapy and familiarization with medical
equipment to reduce fear and promote cooperation. Allowing exploration of
stethoscopes or tongue depressors builds trust. Performing invasive procedures first
increases anxiety, ignoring the child undermines rapport, and restraint should be a last
resort only when necessary for safety.
, Question 9: A nurse is reviewing laboratory results for an infant with suspected
pyloric stenosis. Which electrolyte imbalance should the nurse anticipate?
A. Hyperkalemia
B. Hypochloremic metabolic alkalosis
C. Hypernatremia
D. Hypoglycemia
CORRECT ANSWER: B. Hypochloremic metabolic alkalosis
RATIONALE:Pyloric stenosis causes projectile vomiting of gastric contents, leading to
loss of hydrochloric acid and subsequent hypochloremic metabolic alkalosis.
Potassium may also be depleted (hypokalemia), but alkalosis is the hallmark
imbalance. Hyperkalemia, hypernatremia, and hypoglycemia are not typical primary
findings in this condition.
Question 10: A nurse is teaching an adolescent about concussion management
after a sports injury. Which instruction should the nurse include?
A. "Resume athletic activities as tolerated within 24 hours."
B. "Limit cognitive and physical activities until symptom-free."
C. "Take ibuprofen every 4 hours for headache prevention."
D. "Sleep only in short intervals to monitor for deterioration."
CORRECT ANSWER: B. "Limit cognitive and physical activities until symptom-free."
RATIONALE:Current concussion protocols emphasize physical and cognitive rest until
symptoms resolve to prevent second impact syndrome and promote recovery.
Premature return to activity risks prolonged symptoms. NSAIDs may be used cautiously
for pain but not prophylactically, and uninterrupted sleep is encouraged with periodic
neurological checks rather than forced wakefulness.
Question 11: A nurse is caring for a child with sickle cell disease experiencing a
vaso-occlusive crisis. Which intervention should the nurse prioritize?
A. Administering supplemental oxygen
B. Initiating intravenous hydration
C. Applying cold compresses to painful joints
D. Restricting fluid intake to prevent overload
CORRECT ANSWER: B. Initiating intravenous hydration
RATIONALE:Hydration is critical during vaso-occlusive crisis to reduce blood viscosity
and improve microcirculation, helping to alleviate sickling and pain. Oxygen is indicated
only if hypoxemic. Cold compresses cause vasoconstriction and worsen sickling, while
fluid restriction exacerbates hemoconcentration and should be avoided.
Question 12: A nurse is assessing a newborn at 1 minute of age using the Apgar
score. The infant has a heart rate of 90 bpm, slow irregular respirations, some
