medication that is a direct-acting vasodilator and acts by relaxing pulmonary vessel
musculature. - Answer Nitric oxide
The following arterial blood gas results: pH 7.28, PaO2 74, PaCO2 55, HCO3- 21 and
base deficit -4 indicate - Answer respiratory acidosis.
, Nastassia is a one-hour-old neonate, born at 39 weeks gestation by primary cesarean
birth for fetal bradycardia. She was hypotonic at birth with gasping respirations and a
heart rate of 80. She was provided bulb suctioning and bag mask ventilation and
