A chemotherapy patient's white blood cell (WBC) count is 1.0 ´ 109 /L. There are 60% segmented neutrophils, 38% lymphocytes, and 2% monocytes. What is the correct interpretation of the relative differential?

You are caring for a 69-year-old man with congestive heart failure. His breathing is profoundly labored, his oxygen saturation reads 79% on oxygen via nonrebreathing mask, and he is showing signs of physical exhaustion. Considering that your protocols do not allow you to perform rapid-sequence intubation, you should:

A) insert an oral airway, assist ventilations with a bag-mask device, and transport at once. B) preoxygenate him with a bag-mask device and then perform blind nasotracheal intubation. C) give him Valium for sedation, perform orotracheal intubation, and transport to the hospital at once. D) insert a nasopharyngeal airway and ensure that the nonrebreathing mask is tightly secured to his face.
