Anion Gap = (_ + K) - (Cl + _)
Anion Gap = (Na + K) - (Cl + HCO3)
Anion Gap
Na - (Cl + HCO3)
reason why it’s okay if K is not included?
K = least likely to affect the anion gap
Carbonic acid = _ x 0.031
Carbonic acid = pCO2 x 0.031
Free T4 index = total T4 X _
Free T4 index = total T4 X THBR
THBR = T3U of _ / T3U of _
THBR = T3U of pt/ T3U of control
T3U of control: serum pool/pooled sera
g of NaCl combined with 100mL of water to make NSS:
0.85g per 100mL
Note:
NSS = 0.85%
0.85g of NaCl + 100mL of water
8.5g of NaCl + 1L or 1000mL of water
Amount of NaOCl needed to make 10L of disinfectant:
(10L = total volume)
1L
Amount of NaOCl needed to make 7L of disinfectant:
700mL
Dilution for bleach/NaOCl
1 part of NaOCl + 9 parts of water
1:9 or 1:10?
1:10
