ANSWERS AND RATIONALE

46) A
- valerian is a sedative-hypnotic. It may cause drowsiness when taken in conjunction with decongestant like sudafed.

- neupogen is administered to increase WBC levels. Epogen is administered to increase RBC

48) B
- therapeutic effect of coumadin is: Normal value of PT (control) x 1.5-2 (11-16 secs x 2 = 22-32 secs). Therefore continue giving Coumadin, because PT of 32 secs is within the therapeutic range.
