To prepare 500 gm ? 1224.(d) FP provided by 1% NaCl is -0.58 C. To

4 0.58 FP provided by 1% NaCl
0.52 FP provided by ?
1221.(b) To solve this problem, we must first find
out the amount of drug present in the final solution. = 0.52 x 1 = 0.9% = 0.9 gm/100cc
0.58
The amount of atropine in 1 pint (480cc), 1 in 500
solution: 1225.(d) When only serum creatinine is available,
the following formula (based on sex, weight, and
= 480 x 1 = 0.96 gm of atropine. age of the patient) may be used to convert this
500 value to creatinine clearance.

Now, this 0.96 gm of drug must be present in 1 CrCl = weight(kg)x (140−age)
teaspoonful of the drug solution, therefore we can 72 x serum creatinine (mg/dl)
say:
180 x (140 − 45)
2.2
5cc (1 teaspoonful) contains 0.96 gm CrCl =
72 x 1.5
240cc solution contains ?
CrCl = 71.96 ml/min
= 240 x 0.96 = 46.08 grams of atropine.
5 Therefore, for Jennifer this value should be:

1222.(d) The amount of sodium chloride presents in CrCl (Female) = 0.85 x male (CrCl)
250cc of 0.9% NaCl (Normal Saline) is:
= 0.85 x 71.96ml/minute
= 250 x 0.9 = 2.25 grams NaCl = 61.17ml/minute
100 = 61ml/min

Total equivalents NaCl = weight in grams 1226. (c) The molecular formula for methyl chloride
equivalent weight is CH 3Cl. The mass of a chlorine atom in methyl
chloride is 35.5 gm/mole. The molecular weight of
= 2.25 = 0.03846 equivalents of NaCl. methyl chloride is 50.5 gm/mole (1C = 12, 3H = 3
58.5 and 1Cl = 35.5). Therefore, the % mass of chlorine in
methyl chloride shall be (35.5/50.5) x 100 = 70%
mEqs of NaCl = equivalents x 1000
= 0.03846 x 1000 1227. (b) Each element has a different atomic
