Which of the following oxygen modalities would you recommend for a toddler needing a low FIO2?

A one-month-old male with a ventricular septal defect is referred for a surgical evaluation. Upon arrival, the infant is intubated and ventilated via pressure-limited, time-cycled ventilator with FIO2 of 50%, frequency 20 b/min, PIP 18 cmH2O and 5 cmH2O PEEP. Initial blood gas results are as follows: pH 7.31 PaCO2 58 mmHg HCO3 28 mEq/liter PaO2 68 mmHg Which of the following is the best recommendation?

Ribavirin (Virazole) is administered by using which of the following?

A 33-week newborn is initiated on mechanical ventilation with a time-cycled, pressure-limited ventilator. The following information is available: Peak pressure 28 cmH2O, Rate 55 b/min, Ti 0.5 sec, PEEP 3 cmH2O, flow 8 L/min, Fi02 55% Arterial blood gas results on the above settings are: pH 7.28 PaCO2 52 torr PaO2 65 torr HCO3 25 mEq/L On examination, the breath sounds are diminished with poor chest excursion. Which of the following would be the most appropriate action at this point?

An infant in the NICU is receiving heated, humidified oxygen via a large closed oxyhood operating at 3 L/min. Arterial blood gas analysis reveals an arterial PCO2 of 55 mmHg. What should the neonatal respiratory care practitioner do at this time?

The respiratory care practitioner is performing ventilator rounds in the PICU and observes the needle on the pressure manometer of a ventilator vibrating as it moves to the peak inspiratory pressure level during each inspiration. What is the probable cause of this situation?

A 32-week-old neonate is receiving nasal CPAP of 4 cmH2O with FiO2 of 0.35. Arterial blood gas (ABG) and acid-base data reveal the following: pH 7.44, PaC02 35, PaO2 85, HCO3 23 mEq/L, BE 0 mEq/L. What should the neonatal respiratory therapist do at this time?

A premature infant with hyaline membrane disease has suddenly deteriorated while receiving mechanical ventilation. A chest x-ray has confirmed that the infant suffered a left-sided tension pneumothorax. What recommendation should be made at this time?

A three-year-old boy has presented to the ER with respiratory distress and stridor accompanied by drooling. The physician suspects epiglottitis, but cannot rule out other possibilities, such as severe tonsillitis or foreign body obstruction. Which of the following diagnostic procedures would you recommend in this situation?

The Silverman Anderson score is useful for evaluating which of the following neonatal conditions?
