Panels/ common calculations

Question 1

Basic Metabolic Panel

Answer 1

Na⁺, K⁺, Cl^-, CO2, Ca++, glucose , creatinine, BUN,

“ALL the major cats and anions, plus calcium then BCG!!!

Question 2

Comprehensive Metabolic panel

Answer 2

The basic plus: albumin, total protein, ALP, AST, bilirubin

Question 3

Electrolyte panel

Answer 3

only Na, K, Cl, CO2

Question 4

Liver/ Hepatic Function Panel

Answer 4

albumin, ALT, AST, ALP, bilirubin total and direct, and total protein

Question 5

Lipid Panel

Answer 5

Total cholesterol, HDL, LDL, Trigs

Question 6

Renal function panel

Answer 6

Na+, K+, Ca++, CO2, phosphate,

albumin, BUN, creatinine, glucose,

Question 7

What is the Anion Gap? when does it increase?

Answer 7

the diff btw unmeasured anions and measured cations; Increases in: renal failure, DKA, lactic acidosis, methanol/ethanol/ethylene glycol or salicylate poisoning (common examples)

Question 8

Give two formulas for anion gap calculation

Answer 8

(Na⁺ + K⁺) - (Cl ^-+ HCO3^-)

or

Na - (Cl^-+ HCO3^-)

Question 9

normal anion gap range

Answer 9

longer formula that includes Potassium, 10 to 20;

Shorter formula, 7 to 16

Question 10

How is a w/w percent solution calculated? w/v? v/v?

Answer 10

for w/v: use g/ 100g

for w/v: g/100mL

for v/v: ml/100mL

Question 11

what is molarity?

Answer 11

moles per liter, for concentration of a substance in solution

Question 12

what is the formula for normality?

Answer 12

M x n where M is moles, and n is number of either H+ or OH- units

i.e. : 1.4 M H2SO4, there are 2 H+ that can protonate the solution, so 1.4 x 2 = 2.8 N
