,Q1. A pediatric intensive care patient with septic shock remains hypotensive despite
fluid resuscitation and norepinephrine infusion. Which hemodynamic parameter
would best differentiate between distributive and cardiogenic shock to guide further
management?
A. Central venous pressure (CVP)
B. Cardiac index (CI)
C. Systemic vascular resistance index (SVRI)
D. Mixed venous oxygen saturation (SvO2)
Correct Answer: C. Systemic vascular resistance index (SVRI)
Rationale: In septic shock (distributive), SVRI is typically low, whereas in cardiogenic
shock it is high. Differentiating based on SVRI guides vasopressor versus inotrope
therapy. CVP is unreliable, CI alone may be low in both, and SvO2 can be normal or high
in distributive shock.
Why Wrong:
A - CVP is a poor indicator of volume status and does not differentiate shock types.
B - Cardiac index may be low in both cardiogenic and late septic shock, limiting
differentiation.
D - SvO2 is often high in distributive shock due to shunting, not low as in cardiogenic
shock.

Q2. A pediatric patient with acute respiratory distress syndrome (ARDS) is on
volume-controlled ventilation. Plateau pressure is 30 cm H2O, PEEP is 10 cm H2O,
and tidal volume is 6 mL/kg. Which ventilator adjustment most effectively reduces
ventilator-induced lung injury?
A. Increase PEEP to 15 cm H2O
B. Decrease tidal volume to 4 mL/kg
C. Switch to pressure-controlled ventilation
D. Increase respiratory rate to maintain minute ventilation
Correct Answer: B. Decrease tidal volume to 4 mL/kg
Rationale: Reducing tidal volume to 4-6 mL/kg of predicted body weight is the cornerstone
of lung-protective ventilation in ARDS, limiting overdistension. Plateau pressure is
already at the threshold; increasing PEEP may improve oxygenation but does not reduce
injury, and pressure-controlled mode does not guarantee lower Vt.
Why Wrong:
A - Increasing PEEP recruits lung but does not directly reduce volutrauma.
C - Pressure-controlled ventilation does not automatically reduce tidal volume or
injury.
D - A higher respiratory rate does not address overdistension-induced injury.

Q3. A pediatric patient with severe asthma exacerbation is not responding to
continuous albuterol and IV corticosteroids. Which adjunct therapy is most
appropriate to improve bronchodilation before escalating to intubation?
A. IV magnesium sulfate
B. Subcutaneous epinephrine
C. Inhaled ipratropium bromide
D. Oral theophylline
Correct Answer: A. IV magnesium sulfate
Rationale: IV magnesium sulfate is recommended as adjunct therapy in severe asthma
exacerbations refractory to standard treatment; it provides bronchodilation via calcium
channel antagonism. Subcutaneous epinephrine is an option but not preferred as an
adjunct, ipratropium should be added early, and theophylline is not recommended in acute
exacerbations.
Why Wrong:
B - Subcutaneous epinephrine is a second-line option, not the best adjunct for
refractory bronchospasm.
C - Inhaled ipratropium should be used early, but is not the most effective in
refractory cases.
D - Theophylline has limited efficacy and significant side effects in acute asthma.

Q4. In the context of acute care pediatric nursing, which ethical principle is most
directly challenged when a family demands continuation of futile life-sustaining
treatment against the medical team's recommendation?
A. Autonomy
B. Beneficence
C. Non-maleficence
D. Justice
Correct Answer: B. Beneficence
Rationale: Beneficence, acting in the patient's best interest, is challenged when the
medical team believes treatment is futile, while the family insists on continuing it.
Autonomy applies to the patient's or surrogate's rights, but the conflict centers on what is
beneficial. Non-maleficence and justice are less central.
Why Wrong:
A - Autonomy is important, but the core conflict is about the definition of benefit.
C - Non-maleficence is involved, but the primary ethical duty is beneficence.
