CPN EXAM ACTUAL EXAM 250 QUESTIONS AND CORRECT
DETAILED ANSWERS WITH RATIONALES (VERIFIED
ANSWERS) |ALREADY GRADED A+

Question 1
A 6-month-old infant presents with a sudden onset of inconsolable crying,
drawing knees to chest, and currant-jelly stools. Which condition should the
nurse suspect?
A) Gastroenteritis
B) Pyloric stenosis
C) Intussusception
D) Appendicitis
E) Hirschsprung disease
Correct Answer: C) Intussusception
Rationale: Intussusception is a common cause of intestinal
obstruction in infants, characterized by sudden onset of severe,
colicky abdominal pain (inconsolable crying with knees to chest),
and the classic "currant-jelly" stools due to blood and mucus.

Question 2
Which of the following vital sign changes would be an early indicator of shock
in a pediatric patient?
A) Hypotension
B) Bradycardia
C) Increased urine output
D) Tachycardia
E) Decreased respiratory rate
Correct Answer: D) Tachycardia
Rationale: In pediatric patients, an early compensatory mechanism
for hypovolemia or shock is an increase in heart rate (tachycardia)
to maintain cardiac output. Hypotension is a late and ominous sign.

Question 3
A 4-year-old child is admitted with a diagnosis of croup. The nurse
anticipates which hallmark clinical manifestation?

,A) High-pitched inspiratory stridor at rest
B) Barking (seal-like) cough
C) Drooling and dysphagia
D) Inspiratory and expiratory wheezing
E) Sudden onset of high fever
Correct Answer: B) Barking (seal-like) cough
Rationale: Croup (laryngotracheobronchitis) is characterized by a
distinctive "barking" or "seal-like" cough, often accompanied by
inspiratory stridor, especially when agitated. High-pitched
inspiratory stridor at rest suggests severe obstruction. Drooling and
dysphagia are more characteristic of epiglottitis.

Question 4
When assessing a 12-month-old infant, which developmental milestone
would the nurse expect to find?
A) Walks independently
B) Uses a spoon to self-feed
C) Says 2-3 words meaningfully
D) Rides a tricycle
E) Prints a few letters
Correct Answer: C) Says 2-3 words meaningfully
Rationale: By 12 months, infants typically begin to say 2-3 words with
meaning, understand simple commands, and may pull to stand or
cruise. Walking independently and using a spoon usually come later,
and riding a tricycle/printing letters are much later preschooler
skills.

Question 5
Which intervention is a priority for a pediatric patient experiencing an acute
asthma exacerbation?
A) Administering oral corticosteroids
B) Providing humidified oxygen

,C) Administering a rapid-acting bronchodilator
D) Encouraging fluid intake
E) Performing chest physiotherapy
Correct Answer: C) Administering a rapid-acting bronchodilator
Rationale: A rapid-acting bronchodilator (e.g., albuterol) is the
priority intervention for an acute asthma exacerbation as it quickly
opens the airways and relieves bronchospasm.

Question 6
A parent expresses concern that their 2-year-old child is a "picky eater." What
advice should the nurse provide regarding healthy eating habits for a
toddler?
A) Force the child to eat disliked foods to ensure nutrition.
B) Offer a wide variety of foods, allowing the child to choose from healthy
options.
C) Restrict snacks between meals to ensure hunger at mealtime.
D) Prepare separate meals for the child if they refuse the family meal.
E) Only offer sweet foods as a reward for eating vegetables.
Correct Answer: B) Offer a wide variety of foods, allowing the child to choose
from healthy options
Rationale: Toddlers often exhibit "physiologic anorexia" and are
notoriously picky eaters. Offering a variety of healthy choices and
allowing the child to self-regulate intake within those options is the
best approach. Forcing food, restricting healthy snacks, or making
separate meals can lead to power struggles and unhealthy eating
patterns.

Question 7
What is the most appropriate action for a nurse who identifies a suspected
case of child abuse?
A) Confront the parents directly to obtain a confession.
B) Document objective findings and report to Child Protective Services (CPS).

, C) Delegate the reporting responsibility to the charge nurse.
D) Obtain a physician's order before making a report.
E) Discuss concerns with the family's social circle before reporting.
Correct Answer: B) Document objective findings and report to Child
Protective Services (CPS)
Rationale: Nurses are mandated reporters of suspected child abuse.
The responsibility is to document objective findings and
immediately report to the appropriate agency (CPS). Confronting
parents or delaying the report is inappropriate and potentially
harmful. A physician's order is not required.

Question 8
A 7-year-old child is diagnosed with Type 1 Diabetes Mellitus. The nurse is
teaching the child and parents about insulin administration. Which statement
by the child indicates a need for further teaching?
A) "I need to rotate injection sites to prevent lumps."
B) "I should always eat a snack after my insulin if I'm going to exercise."
C) "I can skip my insulin if I don't feel like eating my meal."
D) "My insulin helps my body use sugar for energy."
E) "I will check my blood sugar before each meal and at bedtime."
Correct Answer: C) "I can skip my insulin if I don't feel like eating my meal."
Rationale: Insulin should never be skipped, even if a meal is not
eaten, as children with Type 1 Diabetes Mellitus require basal
insulin for metabolic needs. Skipping insulin can lead to diabetic
ketoacidosis (DKA). The other statements are correct teaching
points.

Question 9
The nurse is preparing to administer an intramuscular (IM) injection to a 5-
month-old infant. What is the preferred site for this injection?
A) Deltoid
B) Dorsogluteal
