CHEMISTRY AND PHYSICS FOR NURSE
ANESTHESIA ACTUAL TEST PAPER 2026
QUESTIONS AND SOLUTIONS GRADED A+
●● Converting Fahrenheit to Celsius.
Answer: F= (9/5)C+ 32
●● ppm (parts per million).
Answer: An expression of concentration denoting micrograms (10"6 g)
of solute per gram of solution
PPM = (g of solute/g of solvent) X 1,000,000
●● significant figures rules.
Answer: Non-zeros are always significant
Any Zeros between sig figs are significant
Zeros to the right of the decimal point preceding no zeros numbers are
NOT significant (I.e 0.000431)
Trailing zeros are NOT significant (200 = 1 sig; 25,300 = 3 sig)
●● Convert Celsius to Kelvin.
Answer: K = C + 273.15
,●● Common conversion factors.
Answer: 1 Kg=2.2lbs
1 in = 2.54cm
●● Percent concentrations.
Answer: X% concentration = Xg/100mL
To easily convert X% concentration to mg/mL simply move the decimal
point to the right one spot (i.e 0.9% NaCl = 9mg NaCl/mL)
●● 1:1,000 means:.
Answer: 1g/1000ml (g:mL)
●● Max dose lidocaine with Epi.
Answer: 7mg/kg
●● Max dose lidocaine w/o Epi.
Answer: 4.5mg/kg
●● Elements.
Answer: A molecule composed of one kind of atom; cannot be broken
into simpler units by chemical reactions.
, ●● Compounds.
Answer: Molecules that contain more than one element
●● Molecule.
Answer: Two or more atoms held together by covalent bonds.
●● Solutes.
Answer: substance dissolved in a solution
●● solvent (n).
Answer: substance, usually liquid, able to dissolve another substance
(water, ethanol, acetone)
●● Solutions.
Answer: Homogeneous mixtures; Two or more substances
●● covalent bond.
Answer: A chemical bond that involves sharing a pair of electrons
between atoms in a molecule
●● ionic bond.
