2027
Master your Relias Pediatric Nursing RN Competency Exam A v1 with this comprehensive study guide.
Features highly targeted practice questions, verified answers, and detailed rationales mapping out
core pediatric competencies. Accelerate your preparation across critical respiratory distress
assessments, weight-based calculations, pediatric toxicology (acetaminophen/aspirin), and age-
appropriate milestone tracking. Perfect for scoring high on your clinical healthcare assessment.
1. Which condition is the most appropriate indication for endotracheal intubation in a
pediatric patient?
A) Mild tachypnea
B) Intercostal retractions
C) Cyanosis or persistent hypoxia despite oxygen supplementation
D) Nasal flaring only
Rationale: Persistent hypoxia or cyanosis despite supplemental oxygen indicates
respiratory failure and requires advanced airway management.
2. Which symptom is considered an early indicator of increased intracranial pressure
(ICP) in children?
A) Unresponsiveness
B) Seizures
C) Vomiting
D) Fixed pupils
Rationale: Vomiting is often one of the earliest signs of increased ICP as it occurs
suddenly due to stimulation of the brain's vomiting center.
3. Acetaminophen overdosage or chronic high administration in pediatric patients can
cause which of the following?
A) Renal failure
B) Hepatic dysfunction
C) Aggressive behavior
D) Asthma exacerbation
Rationale: Acetaminophen is primarily metabolized by the liver; toxic accumulations
damage hepatocytes and cause severe hepatic necrosis.
4. When calculating weight-based medication doses for an obese pediatric patient, the
nurse must ensure that the dose does what?
1|Page
, A) Never exceeds the standard adult dose
B) Is doubled to match body surface area
C) Is reduced by exactly 50 percent
D) Avoids using standard adult parameters completely
Rationale: Pediatric doses should never exceed the maximum standard adult dose
regardless of how heavy or large the child is.
5. Aminoglycoside therapy and standard aspirin usage in pediatric populations carry a
specific toxicological risk of causing which condition?
A) Xerostomia
B) Hypertension
C) Hearing loss
D) Hepatic encephalopathy
Rationale: Both aminoglycosides and aspirin carry risk profiles that include
ototoxicity, potentially leading to permanent sensorineural hearing loss in children.
6. Anticholinergic medications administered to pediatric patients are most frequently
associated with which side effect?
A) Aggressive behavior
B) Xerostomia
C) Asthma exacerbation
D) Bradycardia
Rationale: Anticholinergics block parasympathetic nerve impulses, which reduces
salivary secretions and leads directly to xerostomia (dry mouth).
7. Alcohol ingestion or toxic alcohol exposure in pediatric patients commonly results in
which acute clinical manifestation?
A) Severe xerostomia
B) Aggressive behavior and hypertension
C) Asthma induction
D) Isolated sensorineural hearing loss
Rationale: Acute alcohol exposure or intoxication in youth often disrupts neurological
circuits, presenting as altered mental status or aggressive behavior accompanied by
autonomic responses like hypertension.
8. Aspirin-induced asthma (AIA) in sensitive pediatric patients occurs due to an
imbalance in which biochemical pathway?
A) Acetaminophen breakdown channels
B) Arachidonic acid metabolism via cyclooxygenase enzymes
C) Aminoglycoside binding paths
D) Parasympathetic anticholinergic pathways
Rationale: Aspirin blocks the cyclooxygenase enzyme within the arachidonic acid
pathway, shunting metabolism toward leukotrienes which causes profound
bronchoconstriction.
9. Which clinical sign represents the earliest compensatory mechanism for a pediatric
patient experiencing respiratory distress?
A) Cyanosis
B) Bradycardia
C) Intercostal retractions
D) Tachypnea
Rationale: Tachypnea is the initial respiratory response to increase minute ventilation
when oxygen demands are not met.
10. A 4-month-old infant is admitted to the pediatric unit. Which developmental milestone
should the nurse expect the infant to exhibit?
2|Page
, A) Sitting up unsupported
B) Pincer grasp development
C) Rolling from stomach to back
D) Creeping along furniture
Rationale: Infants typically learn to roll from front to back around 4 months of age,
whereas sitting unsupported occurs closer to 6 months.
11. What is the preferred site for an intramuscular injection in an infant under 12 months
of age?
A) Deltoid muscle
B) Dorsogluteal muscle
C) Ventrogluteal muscle
D) Vastus lateralis muscle
Rationale: The vastus lateralis is the largest and most developed muscle mass in
infants and contains no major nerves or blood vessels.
12. A 3-year-old child presents with high fever, barking cough, and inspiratory stridor.
Which condition does the nurse suspect?
A) Asthma
B) Bronchiolitis
C) Laryngotracheobronchitis (Croup)
D) Epiglottitis
Rationale: Laryngotracheobronchitis, or croup, typically presents with a hallmark
barking cough and subglottic inflammation causing stridor.
13. Which of the following positions is most appropriate for a child immediately following
a tonsillectomy?
A) High Fowler's position
B) Supine with legs elevated
C) Prone or side-lying position
D) Trendelenburg position
Rationale: A prone or side-lying position promotes drainage of oral secretions and
prevents aspiration while the child emerges from anesthesia.
14. When assessing a dehydrated child, which finding would indicate a severe state of
dehydration rather than mild dehydration?
A) Decreased tears
B) Dry mucous membranes
C) Hypotension and delayed capillary refill over 3 seconds
D) Slightly decreased urine output
Rationale: Hypotension and prolonged capillary refill indicate circulatory
compromise, pointing to severe cardiovascular depletion.
15. What is the standard protocol for assessing a pediatric pulse rate in an infant during
cardiopulmonary resuscitation (CPR)?
A) Radial pulse
B) Popliteal pulse
C) Brachial pulse
D) Femoral pulse alone
Rationale: The brachial artery is easy to access and palpate in infants due to their
short, thick necks which obscure the carotid pulse.
16. A nurse notes that a toddler has a history of ingesting lead-based paint chips. Which
body system is the primary priority for long-term toxicity monitoring?
A) Gastrointestinal system
B) Integumentary system
3|Page
, C) Musculoskeletal system
D) Central nervous system
Rationale: Lead toxicity causes significant neurotoxic effects, including
encephalopathy, cognitive delays, and behavioral impairments.
17. Which congenital heart defect is characterized by a harsh, machine-like murmur
heard throughout the cardiac cycle?
A) Atrial septal defect
B) Patent ductus arteriosus
C) Tetralogy of Fallot
D) Coarctation of the aorta
Rationale: A continuous machine-like murmur is classic for a patent ductus
arteriosus due to blood shunting from the high-pressure aorta to the pulmonary
artery.
18. What is the priority nursing intervention when caring for a child experiencing an
acute sickle cell vaso-occlusive crisis?
A) Cold compress application to joints
B) Strict fluid restriction
C) Intravenous hydration and aggressive pain management
D) Administration of live virus vaccinations
Rationale: Hydration dilutes the concentration of sickled red blood cells to prevent
further occlusion, while pain control addresses tissue ischemia.
19. Which dietary modification is essential for a child newly diagnosed with Celiac
disease?
A) Restriction of dairy products
B) Strict lifelong elimination of gluten
C) High-carbohydrate, low-protein balance
D) Total parenteral nutrition reliance
Rationale: Celiac disease requires a permanent gluten-free diet to prevent small-
bowel mucosal inflammation and nutrient malabsorption.
20. What clinical finding in an infant with a ventriculoperitoneal (VP) shunt would most
strongly alert the nurse to shunt malfunction?
A) Hyperactive bowel sounds
B) High-pitched cry and bulging fontanel
C) Increased urinary output
D) Dry skin textures
Rationale: A bulging fontanel and high-pitched cry are classic signs of increased
intracranial pressure caused by fluid accumulation from a malfunctioning shunt.
21. A nurse is evaluating a 9-month-old infant. Which primitive reflex should be
completely absent by this age?
A) Babinski reflex
B) Moro reflex
C) Parachute reflex
D) Plantar grasp reflex
Rationale: The Moro reflex normally disappears by 4 to 5 months of age; its
persistence indicates potential neurological delays.
22. What is the classic initial sign of intussusception in infants?
A) High-pitched continuous wheezing
B) Projectile vomiting after feeding
C) Sudden, acute abdominal pain with jelly-like stools
D) Increased alertness and hyperactivity
