Question: 1 of 98
A newborn is receiving high-frequency oscillatory ventilation (HFOV) for severe respiratory distress syndrome.
The nurse notes a sudden decrease in chest wall vibration and an increase in PaCO2. Which action should the
A. Increase the frequency of oscillations.
B. Suction the endotracheal tube after instilling normal saline.
C. Check for endotracheal tube displacement or obstruction.
D. Decrease the amplitude of oscillations.

A newborn is receiving high-frequency oscillatory ventilation (HFOV) for severe
respiratory distress syndrome. The nurse notes a sudden decrease in chest wall vibration
and an increase in PaCO2. Which action should the nurse take first?
A. Increase the frequency of oscillations.
B. Suction the endotracheal tube after instilling normal saline.
(Correct) C. Check for endotracheal tube displacement or obstruction.
D. Decrease the amplitude of oscillations.
Correct Answer: C
A sudden loss of chest vibration and rising PaCO2 suggests endotracheal tube obstruction or displacement,
which requires immediate assessment. Increasing frequency or decreasing amplitude would not address the
underlying mechanical issue. Suctioning is not the first step without confirming tube position.

Question: 2 of 98
Which statement best explains why a newborn with persistent pulmonary hypertension (PPHN) is at risk for
hypoxemia despite a normal PaO2 on arterial blood gas?
A. Right-to-left shunting occurs through the foramen ovale and ductus arteriosus.
B. Increased pulmonary blood flow leads to ventilation-perfusion mismatch.
C. Left-to-right shunting causes pulmonary edema and impaired diffusion.
D. Decreased alveolar surface area limits oxygen uptake.

Which statement best explains why a newborn with persistent pulmonary hypertension

(Correct) A. Right-to-left shunting occurs through the foramen ovale and ductus arteriosus.
B. Increased pulmonary blood flow leads to ventilation-perfusion mismatch.
C. Left-to-right shunting causes pulmonary edema and impaired diffusion.
D. Decreased alveolar surface area limits oxygen uptake.
Correct Answer: A
In PPHN, elevated pulmonary vascular resistance causes right-to-left shunting across fetal channels, bypassing
the lungs and leading to hypoxemia. Options B and C describe opposite shunting or different mechanisms. D is
not the primary cause in PPHN.

Question: 3 of 98
A newborn is undergoing therapeutic hypothermia for hypoxic-ischemic encephalopathy. The nurse observes
shivering and a core temperature of 34.5°C. Which intervention is most appropriate?
A. Administer a neuromuscular blocker as prescribed.
B. Increase the cooling blanket temperature.
C. Apply warm blankets to the extremities.
D. Document the finding as expected.

most appropriate?
(Correct) A. Administer a neuromuscular blocker as prescribed.
B. Increase the cooling blanket temperature.
C. Apply warm blankets to the extremities.
D. Document the finding as expected.
Correct Answer: A
Shivering increases metabolic demand and can counteract cooling; neuromuscular blockade is often used to
prevent shivering during therapeutic hypothermia. Increasing temperature would defeat the therapy. Warming
extremities does not address core shivering. Documentation alone is insufficient.

Question: 4 of 98
Which combination of findings in a newborn at 24 hours of life most strongly suggests early-onset neonatal
sepsis?
A. Temperature instability, grunting, and poor feeding.
B. Jaundice, weight loss, and tachypnea.
C. Hyperglycemia, jitteriness, and vomiting.
D. Bradycardia, hypertension, and lethargy.

(Correct) A. Temperature instability, grunting, and poor feeding.
B. Jaundice, weight loss, and tachypnea.
C. Hyperglycemia, jitteriness, and vomiting.
D. Bradycardia, hypertension, and lethargy.
Correct Answer: A
Early-onset sepsis often presents with nonspecific signs such as temperature instability, respiratory distress
(grunting), and feeding difficulties. Jaundice and weight loss are common noninfectious findings. Hyperglycemia
and jitteriness are more associated with metabolic issues. Bradycardia and hypertension are not typical.
