Rationales
Question 1: A 2-week-old infant presents with a history of poor feeding and
lethargy. On examination, the infant is afebrile but appears mildly tachypneic.
A non-blanching, petechial rash is noted on the trunk and extremities. Which
of the following is the priority nursing intervention?
A. Administer a dose of acetaminophen
B. Obtain a complete blood count and blood cultures
C. Prepare for a lumbar puncture
D. Initiate droplet precautions
CORRECT ANSWER: B. Obtain a complete blood count and blood cultures
Rationale: A non-blanching petechial rash in a neonate is a critical sign that suggests
sepsis, often caused by Group B Streptococcus or Neisseria meningitidis. The priority is
to initiate a sepsis workup, which begins with obtaining blood cultures before antibiotic
therapy is started. While a lumbar puncture is part of the complete sepsis evaluation, it
is not the initial priority over obtaining cultures.
Question 2: A 6-month-old infant is brought to the clinic for a well-child visit.
The parent reports that the infant is no longer sleeping through the night and
wakes up crying. The nurse notes the infant is drooling and frequently putting
fingers in the mouth. Which of the following is the most likely cause of this
behavioral change?
A. Acute otitis media
B. Separation anxiety
C. Teething
D. Nocturnal myoclonus
CORRECT ANSWER: C. Teething
Rationale: Teething typically occurs around 6 months of age and is characterized by
irritability, drooling, sleep disturbances, and increased finger-sucking or biting to relieve
,gum pressure. While separation anxiety can cause sleep regression, it typically peaks
later (8-10 months). Acute otitis media would likely present with fever, pulling at ears,
and signs of infection.
Question 3: A 4-year-old child with a history of asthma is brought to the
emergency department with a respiratory rate of 40 breaths/min, a heart rate
of 150 bpm, and an oxygen saturation of 90% on room air. Which of the
following findings indicates the need for immediate intubation?
A. Nasal flaring
B. Accessory muscle use
C. A silent chest on auscultation
D. Prolonged expiratory phase
CORRECT ANSWER: C. A silent chest on auscultation
Rationale: A "silent chest" indicates extremely poor air movement due to severe
bronchoconstriction and is a sign of imminent respiratory failure. This is an indication
for immediate intubation and mechanical ventilation. Nasal flaring, accessory muscle
use, and a prolonged expiratory phase indicate moderate to severe distress but are not
the classic indicators for immediate intubation as the "silent chest" is.
Question 4: A 10-year-old child is prescribed methylphenidate for attention-
deficit/hyperactivity disorder (ADHD). The nurse is providing medication
education to the parent. Which of the following statements made by the parent
indicates the need for further teaching?
A. "I should give the medication about 30 minutes before a meal."
B. "I should monitor my child’s weight regularly as appetite suppression is common."
C. "I can expect to see an improvement in symptoms immediately after the first dose."
D. "This medication may worsen any underlying tics or Tourette syndrome."
CORRECT ANSWER: C. "I can expect to see an improvement in symptoms
immediately after the first dose."
Rationale: Methylphenidate is a central nervous system stimulant that takes effect
relatively quickly; however, full therapeutic effects typically take several days to weeks to
become fully optimized, not immediately after the first dose. The other statements are
accurate: it should be given 30-60 minutes before meals to maximize absorption and
minimize loss of appetite, weight should be monitored, and it can exacerbate tics.
Question 5: An 8-year-old child presents to the clinic with a history of a sore
throat for 3 days. On examination, the nurse notes a temperature of 101.2°F,
,enlarged anterior cervical lymph nodes, and erythematous tonsils with
exudates. Which of the following is the priority nursing action?
A. Administer a dose of ibuprofen
B. Obtain a rapid strep test
C. Instruct the parent to increase fluid intake
D. Provide a throat culture
CORRECT ANSWER: B. Obtain a rapid strep test
Rationale: The clinical presentation (fever, sore throat, cervical lymphadenopathy, and
tonsillar exudate) is suggestive of Group A beta-hemolytic streptococcus (GABHS). A
rapid strep test is the priority diagnostic tool to quickly identify the infection and allow
for prompt antibiotic therapy to prevent complications such as rheumatic fever. A throat
culture is indicated if the rapid test is negative and suspicion is high.
Question 6: A 12-month-old child is scheduled to receive the measles, mumps,
and rubella (MMR) vaccine. The parent asks the nurse if the child can receive
a dose of acetaminophen before the vaccine to prevent fever. Which of the
following is the best response?
A. "Yes, you may give the acetaminophen immediately before the injection."
B. "No, antipyretics should be avoided because they can reduce antibody response."
C. "Yes, but only if the child has a history of febrile seizures."
D. "No, antipyretics are only effective after the fever appears."
CORRECT ANSWER: B. "No, antipyretics should be avoided because they can
reduce antibody response."
Rationale: Prophylactic administration of antipyretics (acetaminophen or ibuprofen)
before or immediately after vaccination is not recommended for MMR and varicella
vaccines as it may reduce the immune response and antibody titers. Antipyretics should
be given only if fever develops, and caution is advised for children with a history of
febrile seizures.
Question 7: The nurse is caring for a newborn with a myelomeningocele in the
immediate postoperative period. The newborn is placed in the prone position.
Which of the following is the most important nursing intervention to prevent
complications associated with this position?
A. Pad the pressure points with soft blankets
B. Monitor the fontanels for signs of dehydration
C. Ensure that the sac is covered with a sterile, moist dressing
D. Assess for any redness or breakdown over the surgical site
, CORRECT ANSWER: D. Assess for any redness or breakdown over the surgical
site
Rationale: While all options are important, in the prone position, the priority is to
regularly assess the skin over the surgical site and any other pressure points to prevent
skin breakdown. A sterile moist dressing is more crucial preoperatively to keep the sac
moist and intact. After surgery, the sac is closed, and the focus shifts to wound healing.
Question 8: A 14-year-old adolescent presents to the emergency department
with a severe headache, vomiting, and nuchal rigidity. The nurse observes that
the adolescent's eyes are deviated downward and outward, and the pupil is
dilated on the right side. Based on these findings, which of the following is the
priority nursing intervention?
A. Place the adolescent in a dark, quiet room
B. Administer a dose of dimenhydrinate for nausea
C. Prepare for immediate intracranial pressure monitoring
D. Notify the healthcare provider of the possible herniation syndrome
CORRECT ANSWER: D. Notify the healthcare provider of the possible
herniation syndrome
Rationale: The signs of downward and outward eye deviation (setting sun sign) and a
dilated pupil suggest uncal herniation, an emergency that requires immediate
notification of the provider. This is a sign of elevated ICP that has progressed to a critical
stage, and further deterioration can lead to respiratory arrest.
Question 9: A 3-year-old child is being treated for acute gastroenteritis with
moderate dehydration. The healthcare provider orders intravenous fluids.
Which of the following is the preferred solution for initial fluid resuscitation in
this child with severe dehydration?
A. 0.45% normal saline with 5% dextrose
B. D5W (5% dextrose in water)
C. Lactated Ringer's solution
D. 0.9% normal saline
CORRECT ANSWER: D. 0.9% normal saline
Rationale: For the treatment of severe dehydration, 0.9% normal saline is the preferred
isotonic solution for rapid volume expansion. It restores intravascular volume effectively.
D5W is hypotonic and not appropriate for volume resuscitation, while lactated Ringer's
can be used but 0.9% NS is the most commonly recommended initial fluid for
shock/severe dehydration.
