Answer to Question 1

ANS: C
The partial pressure of a gas in a mixture can be calculated by multiplying the total pressure of the mixture by the percentage of the mixture that the gas in question occupies. Therefore, 0.5  760 mm Hg = 380 mm Hg.

Answer to Question 2

ANS: D
No antibiotic was mentioned in the scenario. There is no history of the patient receiving any medication for this problem, so compliance is not an issue with this situation. It is not normal to have secretions at a suture site.
