Which does the nurse choose to deliver the highest FiO2 for a client without an artificial airway?
1. A nonrebreathing mask
2. Nasal reservoir Oxymizer®
3. Snug fitting Venturi mask
4. Nasal cannula at 15 L/min
1
1. The nurse chooses the nonrebreather mask to deliver the highest FiO2 without in-tubation because it is able to provide up to 80% oxygen.
2. The Oxymizer® delivers an enhanced FiO2 in a 2:1 ratio with a nasal cannula without use of a face mask or artificial airway.
3. A Venturi mask delivers between 24% and 50% oxygen.
4. The nasal cannula delivers up to 6 L/min oxygen; oxygen greater than 6 L/min. is too irritating to the nasal mucosa.

Consider the following pharmacoeconomic study designs and choose the one that is applicable to a pharmaceutical analysis that is designed to measure the outcomes of a blood pressure reduction (antihypertensive) drug in terms of natural health units
The costs of the drug are measured in dollars, and the value is measured by a unit of effective-ness, arbitrarily defined as a lowering of the diastolic blood pressure by 1 mm Hg. This analysis is classified as a: a. Cost-benefit analysis (CBA) b. Cost-effective analysis (CEA) c. Cost-utility analysis (CUA) d. Cost-minimization analysis (CMA)
