Professional Nursing 624 Exam 1
With Complete Solution
As Mr. Martin's oxygenation deteriorates, the nurse has an order to titrate
pulse oximetry to keep it greater than 90%. Because Mr. Martin is currently
at 6 L/NC (44% oxygen), what would be the best options for delivery of
oxygen should the levels drop below 90%? - ANSWER simple mask
partial rebreather mask
venturi mask
face tent
As the nurse is placing the oxygen, she reflects on the percentage of oxygen
being delivered via nasal cannula (NC) at 2 L. What would be the correct
amount? - ANSWER 28%

crackles should disappear at 3 months in babies
During an assessment, the nurse notices that a client's breathing pattern
follows a cycle of progressively increasing in depth, then progressively
decreasing in depth, followed by a period of apnea. Which appropriately
