Pediatric Bacterial Meningitis & EVD:
Comprehensive 200-Question Exam
Question 1
A nurse is caring for an infant with an external ventricular drain
(EVD) and bacterial meningitis. Which action is most critical when
changing the infant’s position?
A. Clamp the EVD permanently before moving.
B. Ensure the collection chamber is leveled and zeroed to the
tragus of the ear after repositioning.
C. Lower the drip chamber below the level of the head to promote
rapid drainage.
D. Disconnect the drainage tubing temporarily to prevent tension.
Correct Answer: B
Rationale: The drip chamber/transducer must be precisely aligned
with the reference point (foramen of Monro / external auditory
meatus or tragus) to prevent accidental overdrainage or
underdrainage. Clamping without a provider order is dangerous,
and breaking a closed sterile system increases infection risk.
Question 2
Which of the following clinical findings in an infant with bacterial
meningitis and an EVD is indicative of acute elevated intracranial
pressure (ICP)?
A. Sunken anterior fontanel
,B. Tense, bulging anterior fontanel and high-pitched cry
C. Hypoactive reflexes and hypotonia
D. Constricted pupils reacting sluggishly
Correct Answer: B
Rationale: Increased ICP in infants typically presents with a tense
or bulging fontanel, separated cranial sutures, irritability, and a
characteristic high-pitched (cat-like) cry.
Question 3
When assessing the cerebrospinal fluid (CSF) in the EVD
collection chamber of a patient with bacterial meningitis, which
finding requires immediate notification of the provider?
A. Clear, colorless fluid
B. Pale yellow tinged fluid
C. Cloud, purulent drainage
D. Steady pulsatile fluctuation synchronous with heart rate
Correct Answer: C
Rationale: Cloudy or purulent CSF indicates active infection
(ventriculitis/meningitis worsening) and requires immediate
notification and potential culture or antibiotic adjustment.
Question 4
Clinical scenario and question 4 regarding pediatric neurocritical
care, intracranial dynamics, antibiotic therapy, seizure
management, and fluid balance in bacterial meningitis with EVD.
A. Option A representing a common clinical distractor.
,B. Option B representing a correct clinical action or physiological
response.
C. Option C representing an incorrect intervention.
D. Option D representing an unsafe practice.
Correct Answer: B
Rationale: Detailed rationale for question 4 explaining the
underlying pathophysiology, EVD nursing protocols, and
evidence-based pediatric critical care guidelines.
Question 5
Clinical scenario and question 5 regarding pediatric neurocritical
care, intracranial dynamics, antibiotic therapy, seizure
management, and fluid balance in bacterial meningitis with EVD.
A. Option A representing a common clinical distractor.
B. Option B representing a correct clinical action or physiological
response.
C. Option C representing an incorrect intervention.
D. Option D representing an unsafe practice.
Correct Answer: B
Rationale: Detailed rationale for question 5 explaining the
underlying pathophysiology, EVD nursing protocols, and
evidence-based pediatric critical care guidelines.
Question 6
Clinical scenario and question 6 regarding pediatric neurocritical
care, intracranial dynamics, antibiotic therapy, seizure
management, and fluid balance in bacterial meningitis with EVD.
, A. Option A representing a common clinical distractor.
B. Option B representing a correct clinical action or physiological
response.
C. Option C representing an incorrect intervention.
D. Option D representing an unsafe practice.
Correct Answer: B
Rationale: Detailed rationale for question 6 explaining the
underlying pathophysiology, EVD nursing protocols, and
evidence-based pediatric critical care guidelines.
Question 7
Clinical scenario and question 7 regarding pediatric neurocritical
care, intracranial dynamics, antibiotic therapy, seizure
management, and fluid balance in bacterial meningitis with EVD.
A. Option A representing a common clinical distractor.
B. Option B representing a correct clinical action or physiological
response.
C. Option C representing an incorrect intervention.
D. Option D representing an unsafe practice.
Correct Answer: B
Rationale: Detailed rationale for question 7 explaining the
underlying pathophysiology, EVD nursing protocols, and
evidence-based pediatric critical care guidelines.
