The nurse is caring for a patient with pneumonia and fulminant pulmonary arterial hypertension. The patient is intubated and mechanically ventilated receiving inhaled nitric oxide (iNO). Additionally, the patient has a central line with multiple continuous infusions, including norepinephrine, vecuronium, morphine, and propofol. During the shift, the nurse begins to have difficulty breathing, a dry throat, syncope, and chest pain. Which action does the nurse take first?

The patient with well-controlled chronic obstructive pulmonary disorder presents with a 3 day history of increased cough with sputum production, fever, and malaise. Upon assessment, breath sounds are clear after coughing and the patient appears to breathe comfortably with no retractions or nasal flaring. His chest x-ray is clear and his screening complete blood count is largely normal, with exception of a white blood cell count of 16. The nurse anticipates the provider to order which medication(s)? Select all that apply. 

The 3.2 kg patient with persistent pulmonary hypertension of the newborn (PPHN) has the following order: Infuse norepinephrine 0.05 mcg/kg/min IV and titrate q15 minutes by 0.05 mcg/kg/min to maintain mean arterial pressure between 45 and 55 mm Hg. Overnight, the norepinephrine had been titrated to 0.25 mcg/kg/min for persistent hypotension. At 0900, the MAP rose to 62 mm Hg and the nurse decreased the infusion from 0.25 mcg/kg/min to 0.20 mcg/kg/min. At 0905, the patient’s blood pressure fell to 42 mm Hg.
