Ampule vs. Vial | |
ampule
- stripe around the neck facilitates
opening; |
vial WHICH contains solution
- by using sterile needle, avoid corning, so do 45° needle's angle to
rubber surface; vial WHICH contains powder - transfer diluent into vial; |
CphT calculation no. 90:
Avoid potential "corning", WHEN pushing sterile needle through vial's rubber stopper ["lid" is not a usage here], sterile needle's angle to rubber surface should be approximately
(a) 45°
(b) 72°
(c) 90°
(d) 100°
Answer: 45°;
CphT calculation no. 113:
Among the following G sizes, which needle might cause "corning" most likely?
(a) 23 G
(b) 20 G
(c) 16 G
(d) 13 G
Answer: 13 G ; Remark: opposite to capsule size;
Apothecary
16 fl oz, aka 1 pt;

Capsule size
CphT calculation no. 115:
Which is the largest capsule size among following sizes?
(a) size 000
(b) size 0
(c) size 2
(d) size 5
Answer: size 000; Remark: opposite to needle size;
20 drops, aka 1 milliliter; Drop cannot be accurately measured, because fluid type may vary, because syringe's needle size may vary, ... ; However, ml can be measured accurately;
5 ml, aka 1 tsp;
15 ml, aka 1 tbsp; aka 3 tsp;
8 fl oz, aka 1 cup [small];
phT calculation no. 39:
For accurately transferring of volume < 5ml, which device should be used:
(a) pipet (b) jar (c) graduated cylinder (d) volumetric flask
Answer: pipet;
Glass pipets can accurately transfer 1, 2, 5, 10, 25 ml of liquid; Micro-pipets are also available to measure 1~20, 1~100, 1~200, 1~1000 micro-liters aka 10^-6 l;
Syringe sizes can be 0.5 ml ~ 60 ml;
1000 ml, aka 1 L, aka 10 dl;
phT calculation no. 38:
For measuring small volume, which device should be used:
(a) disposable syringe (b) graduated cylinder (c) volumetric flask (d) spatula
Answer: disposable syringe;
1:1000 = 1mg/ml;
1:100 = 10mg/ml;
1:10 = 100mg/ml;
NS = Normal Saline = (900mg/100ml), aka 0.9% NaCl aka Na in mg, Cl in ml;
Solid Metric
1000 g, aka 1 kg;
1000 mg, aka 1 g;
1 kg, aka 2.2 lb;
1 oz, aka 28.35 g;
30 ml [rounded from ⌐29.57¬ ml], aka 1 fl.oz.;
33.8 fl oz, aka 1 L;
454 gm [rounded from ⌐453.59¬ ], aka 1 lb;
480 ml [rounded from ⌐473¬ ml], aka 1 pt;
phT calculation no. 40:
100°C temperature is
(a) 100°F (b) 273°K (c) 0°F (d) 212°F
Answer: 212°F;
Temperature
9°C = 5°F - 160;
Remark: mb "millibar by heterodyned effect" pressure based temperature is not available in ACT1 languages ... for ACT2 and ACT3, must learn oriental languages ... ;
phT calculation no. 19:
WHEN re-starting laminar flow hood, how long CphT should wait?
(a) 1 minute (b) 30 minutes (c) 1 day (d) 30 days
HEPA [high efficiency particulate air] filter removes particles > 0.3 microns [0.3 μm], to purify air flow in work area, so laminar flow hoods are built [approx. 1 laminar flow covers work surface by uniform velocity of 33meter/min]; Laminar flow hood should be operating continuously. Assume that its blower was broken, or it was turned off for changing filter, or it was off for saving energy at close-time-period, so WHEN re-starting time, CphT turns it on, and waits for 30 minutes for purifying air flow in work area.
phT calculation no. 37:
Either analytical balance or electronic balance should be used if measuring wt
