Calories provided by 250cc 5% glycerol:

= 250 x 5 x 4.3 = 53.75 calories

192.(d) 900 calories.
To prepare 8cc (5%) 5cc (2%)
1 gram fat provides 9 calories. Therefore, calories To prepare 500cc (5%) ?
provided by 500cc, 20% fat solution:
= 500 x 5 = 312.50cc (2% acetic acid)
= 500 x 20 x 9 = 900 calories 8

312.5cc (2% acetic acid) should be mixed with
193.(c) The amount of Alphagan present in each (500cc -312.5cc) 187.5cc (10% acetic acid) to
drop: prepare 500cc (5% acetic acid).

= 0.1 x 0.2 = 0.0002 gm = 0.2 mg 198.(c) 20 tablets.

199.(d) 297.61 mEqs
194.(d) 50 milligrams.
Equivalent weight = Molecular weight
The amount of Timolol in mg: Number of valence
= 0.5 x 10 = 0.05 gm = 50 mg
100
Equivalent weight = 84 = 84 gm
195.(a) The patient is using 75 mg twice a week for 1
4 months or 16 weeks, therefore the total dose of
Haldol decanoate required is: 1 equivalent weight (NaHCO3) = 84 gm
1 milliequivalent (NaHCO3) = 84 mg
= 75 x 2 x 16
= 2400 mg The amount of NaHCO3:
The number of vials of Haldol required:
= 50 x 0.5
= 2400 = 24 vials = 25 gm NaHCO3
100 = 25000 mg NaHCO3

196.(b) 60 calories Milliequivalents of NaHCO3:

Calories provided by 500cc 3% amino acid: = 25000 = 297.61 mEq

= 500 x 3 x 4 = 60 calories
100 200.(c) 70 days.

197.(c) 312.50cc 2% acetic acid and 187.5cc 10% t 1/2 = 0.693
acetic acid: k
0.693
