Question 1: A 6-month-old infant is brought to the pediatric clinic for a routine well-child checkup. The
parents express concern that the infant is not yet sitting up without support and only babbles
occasionally. Based on normal growth and developmental milestones, what is the most appropriate
nursing response to the parents' concern?
A. Recommend an immediate referral to a pediatric neurologist for a comprehensive developmental
evaluation.
B. Reassure the parents that these findings are within normal limits for a 6-month-old infant and
encourage continued tummy time.
C. Instruct the parents to begin intensive physical therapy sessions to accelerate the infant's motor skill
development.
D. Advise the parents to restrict the infant's diet to pureed foods to prevent any potential choking
hazards during play.
CORRECT ANSWER: B. Reassure the parents that these findings are within normal limits for a 6-month-
old infant and encourage continued tummy time.
Rationale: At 6 months of age, it is a normal developmental milestone for an infant to sit with support or
briefly without support, and babbling is the expected vocalization pattern. Therefore, reassuring the
parents that these findings are within normal limits is the most appropriate and evidence-based nursing
response. Recommending an immediate neurologist referral or intensive physical therapy is premature
and may cause unnecessary parental anxiety, as the infant is not demonstrating clear red flags for
developmental delay. Restricting the diet does not address the developmental concern and is not
indicated at this age, as infants typically begin trying pureed foods around 6 months.
Question 2: A 2-year-old toddler is admitted to the pediatric unit with a diagnosis of acute
gastroenteritis. The child is experiencing frequent temper tantrums, screaming, and throwing toys
when the nurse attempts to perform assessments. Which of the following is the most appropriate
nursing intervention to manage this behavior?
A. Restrict the parents from the room to minimize the child's agitation and allow the nurse to complete
the assessment quickly.
,B. Ignore the tantrum completely and proceed with the assessment, as giving attention will only
reinforce the negative behavior.
C. Provide the toddler with simple, limited choices and maintain a consistent, predictable routine to
foster a sense of control.
D. Administer a prescribed mild sedative to ensure the child remains calm and cooperative during all
nursing procedures.
CORRECT ANSWER: C. Provide the toddler with simple, limited choices and maintain a consistent,
predictable routine to foster a sense of control.
Rationale: Toddlers are in Erikson's stage of autonomy versus shame and doubt, and they often express
their desire for independence through negativism and temper tantrums. Providing simple, limited
choices (e.g., "Do you want me to check your ears first or your heart first?") gives the toddler a sense of
control and can significantly reduce resistance. Restricting parents increases separation anxiety and
agitation, while ignoring the tantrum during a necessary medical assessment is impractical and unsafe.
Administering sedatives for routine assessments is inappropriate and poses unnecessary
pharmacological risks.
Question 3: A 4-year-old preschooler is scheduled for a tonsillectomy. The child asks the nurse, "Will
my throat grow back together like a scraped knee?" What is the most appropriate nursing response to
address the child's concern?
A. "Yes, your throat will heal just like a scraped knee, so you do not need to worry about it at all."
B. "Your throat will heal, but it is on the inside, so you will not see a scab like you do on your knee."
C. "No, the doctor is going to remove the tonsils permanently, and they will not grow back like a scraped
knee."
D. "You are too young to understand how surgery works, so just focus on getting a popsicle afterward."
CORRECT ANSWER: B. "Your throat will heal, but it is on the inside, so you will not see a scab like you
do on your knee."
Rationale: Preschoolers engage in magical thinking and often relate new experiences to familiar
concepts, such as a scraped knee. The most appropriate response uses simple, concrete language that
validates the child's frame of reference while accurately explaining the internal healing process. Telling
the child it will heal "just like a scraped knee" without qualification may lead to confusion when they do
not see an external scab. Dismissing the child's question or stating they are too young to understand
undermines trust and increases anxiety.
Question 4: An 8-year-old school-age child is hospitalized for a fractured femur and is expressing
feelings of inadequacy because they cannot keep up with their peers in physical activities. According
to Erikson's stages of psychosocial development, which nursing intervention is most appropriate to
support this child?
A. Encourage the child to participate in age-appropriate, non-weight-bearing activities such as reading,
drawing, or playing board games to foster a sense of industry.
B. Allow the child to sleep as much as possible to promote physical healing, as rest is the only priority
during bone recovery.
C. Assign the child a mentor who is a professional athlete to inspire them to overcome their physical
,limitations.
D. Tell the child that fractures are common and they should not feel inadequate, as everyone gets hurt
sometimes.
CORRECT ANSWER: A. Encourage the child to participate in age-appropriate, non-weight-bearing
activities such as reading, drawing, or playing board games to foster a sense of industry.
Rationale: School-age children are in Erikson's stage of industry versus inferiority, where they derive
self-esteem from mastering tasks and feeling productive. Encouraging participation in non-weight-
bearing activities allows the child to experience success and maintain a sense of industry despite
physical limitations. Excessive sleep does not address the psychosocial need for productivity. Assigning a
professional athlete mentor is unrealistic and may increase feelings of inadequacy. Dismissing the child's
feelings invalidates their emotional experience.
Question 5: A 15-year-old adolescent is admitted to the pediatric unit with a diagnosis of
inflammatory bowel disease. The adolescent requests that the parents not be present during the
discussion of the treatment plan. What is the most appropriate nursing action?
A. Deny the request, as parents are legally responsible for all medical decisions until the adolescent
reaches 18 years of age.
B. Honor the request and provide the adolescent with private time to discuss the treatment plan,
fostering autonomy and trust.
C. Allow the parents to stay but instruct them to remain silent while the nurse speaks directly to the
adolescent.
D. Postpone the discussion until a child life specialist is available to mediate between the adolescent and
the parents.
CORRECT ANSWER: B. Honor the request and provide the adolescent with private time to discuss the
treatment plan, fostering autonomy and trust.
Rationale: Adolescents are in Erikson's stage of identity versus role confusion and highly value privacy
and autonomy. Honoring the adolescent's request for privacy during discussions about their care fosters
trust, encourages open communication, and supports their developing independence. While parents are
generally involved in medical decisions, adolescents have a right to confidential discussions about their
health, especially regarding sensitive topics or personal preferences. Denying the request or forcing
parental presence can damage the therapeutic relationship and cause the adolescent to withhold
important health information.
Question 6: A nurse is assessing the anterior fontanelle of a 14-month-old infant during a well-child
visit. Which of the following findings should the nurse report to the healthcare provider immediately?
A. The anterior fontanelle is flat and firm when the infant is sitting quietly.
B. The anterior fontanelle is slightly depressed when the infant is crying.
C. The anterior fontanelle is still open and measures approximately 1 cm in diameter.
D. The anterior fontanelle is bulging and tense when the infant is calm and upright.
CORRECT ANSWER: D. The anterior fontanelle is bulging and tense when the infant is calm and
upright.
, Rationale: The anterior fontanelle typically closes between 12 and 18 months of age, so a 1 cm open
fontanelle at 14 months is a normal finding. A flat and firm fontanelle is also a normal, expected finding.
A slightly depressed fontanelle can occur with crying or may indicate mild dehydration, but it is not an
immediate emergency. However, a bulging and tense fontanelle when the infant is calm and upright is
an abnormal finding that indicates increased intracranial pressure (ICP), which requires immediate
medical evaluation to rule out conditions such as hydrocephalus, meningitis, or intracranial bleeding.
Question 7: A mother of a 3-year-old child reports that the child has recently started saying "no" to
every request and insists on doing everything independently, often resulting in frustration. What is
the best nursing response to the mother?
A. "This is a sign of oppositional defiant disorder, and you should seek a psychological evaluation for
your child."
B. "Your child is exhibiting normal negativism, which is a healthy part of developing autonomy and
independence."
C. "You should strictly punish the child every time they say 'no' to eliminate this disrespectful behavior."
D. "This behavior indicates that your child is spoiled, and you need to establish stricter household rules."
CORRECT ANSWER: B. "Your child is exhibiting normal negativism, which is a healthy part of
developing autonomy and independence."
Rationale: Negativism, characterized by frequent use of the word "no" and a strong desire for
independence, is a hallmark of normal toddler development. It reflects the child's attempt to establish
autonomy and self-identity. Reassuring the mother that this is a normal, healthy developmental phase
helps reduce parental anxiety and promotes positive parenting strategies, such as offering limited
choices. Labeling the behavior as a psychological disorder, spoiled, or deserving of strict punishment is
inaccurate, developmentally inappropriate, and harmful to the child's psychosocial development.
Question 8: A 5-year-old child is admitted to the hospital for a surgical procedure. The child becomes
extremely anxious when the nurse prepares to start an intravenous (IV) line, stating, "Don't cut me
open!" What is the best explanation for the child's reaction?
A. The child is experiencing separation anxiety from the parents.
B. The child has a realistic understanding of surgical procedures and is expressing valid fear.
C. The child is demonstrating fear of bodily injury and mutilation, which is common in preschoolers.
D. The child is manipulating the nurse to avoid the painful procedure.
CORRECT ANSWER: C. The child is demonstrating fear of bodily injury and mutilation, which is
common in preschoolers.
Rationale: Preschoolers have a vivid imagination and often fear bodily injury or mutilation, believing that
their skin is a fragile barrier that, once broken, will cause their insides to leak out. They do not fully
understand the concept of internal anatomy or the healing process. The child's statement reflects this
developmental fear, not manipulation or a realistic understanding of surgery. Addressing this fear
requires simple, concrete explanations and reassurance that the body will heal, rather than dismissing
the concern as manipulation.
