Nagelhout Chapter 15: Chemistry and Physics for Nurse Anesthesia

Solubility Correct Answer:- The ability of one substance to dissolve in another at a given temperature and pressure (for anesthesia think of gas dissolved into a liquid) Converting Fahrenheit to Celsius Correct Answer:- F= (9/5)C+ 32 ppm (parts per million) Correct 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 Correct 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.) Trailing zeros are NOT significant (200 = 1 sig; 25,300 = 3 sig) Convert Celsius to Kelvin Correct Answer:- K = C + 273.15 Common conversion factors Correct Answer:- 1 Kg=2.2lbs 1 in = 2.54cm Percent concentrations Correct 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: Correct Answer:- 1g/1000ml (g:mL) Max dose lidocaine with Epi Correct Answer:- 7mg/kg Max dose lidocaine w/o Epi Correct Answer:- 4.5mg/kg Elements Correct Answer:- A molecule composed of one kind of atom; cannot be
