  1. A neonate with persistent pulmonary hypertension (PPHN) is not responding adequately to conventional therapy. Which inhaled medication is commonly used to reduce pulmonary vascular resistance?

    Answer: Inhaled nitric oxide (iNO)

    Inhaled nitric oxide selectively dilates pulmonary vasculature, reducing pulmonary vascular resistance in PPHN without causing systemic hypotension.

  2. A neonate with BPD is being treated with diuretics. Which electrolyte imbalance is most commonly associated with chronic furosemide use in neonates?

    Answer: Hyponatremia and hypokalemia

    Furosemide causes urinary losses of sodium, potassium, and chloride, leading to hyponatremia, hypokalemia, and hypochloremic metabolic alkalosis.

  3. What is the primary physiologic purpose of PEEP in neonatal mechanical ventilation?

    Answer: To prevent alveolar collapse at end-expiration

    PEEP maintains functional residual capacity by preventing alveolar collapse between breaths, improving oxygenation and reducing atelectasis.

  4. A nurse is caring for a neonate with pulmonary interstitial emphysema (PIE) on the right side. Which positioning intervention may help?

    Answer: Right lateral decubitus positioning

    Right lateral decubitus positioning compresses the affected lung, reducing air entry and promoting resolution of PIE on the right side.

  5. Which of the following correctly describes the difference between High-Frequency Oscillatory Ventilation (HFOV) and High-Frequency Jet Ventilation (HFJV)?

    Answer: HFOV uses active expiration while HFJV relies on passive recoil

    HFOV uses active inspiration and expiration via oscillation, while HFJV delivers high-velocity gas pulses with passive exhalation relying on chest recoil.

  6. A neonate born at 35 weeks gestation develops tachypnea, grunting, and retractions within 2 hours of birth that resolve by 24-48 hours. What is the most likely diagnosis?

    Answer: Transient tachypnea of the newborn (TTN)

    Transient tachypnea of the newborn results from delayed resorption of fetal lung fluid and typically resolves within 24-72 hours in late-preterm or term neonates.

  7. During resuscitation of a term newborn who is not breathing, PPV is initiated but chest rise is not seen. What is the FIRST corrective step according to NRP guidelines?

    Answer: Reposition the airway and ensure a proper mask seal (MR. SOPA)

    NRP MR. SOPA steps begin with Mask adjustment and Reposition before escalating to Suction, Open mouth, Pressure increase, and Airway (intubation).
