20
Q

Calculate the creatinine clearance of a 24 hour urine specimen using the following formula and data:
(Uc/Pc) x (TV/1440)

Uc = 650 mg/L
Pc = 6.2 mg/L
TV = 1600 mL
A

(650/6.2) x (1600/1440) = 116.5

21

lymphocytes

24
Q

Calculate the dose or doses of Rhogam:

Fetal cells seen = 30
Adult cells counted = 2210

(fetal/Adult) x 100 = % fetal cells

(% x 50)/30 = vials of Rhogam

A

30/2210 x 100 = 1.36
1.4 x 50/30 = 2.3 + 1 vial
3 vials of Rhogam
