The LD50 of ethlyl alcohol (ethanol) is 5 g/kgA shot, a 12 ounce beer, and 5 ounces of wine each contain 14 grams of ethanol. b.) Theoretically (ignoring pharmacogenomics and tolerance), how many shots could a 115 pound student drink before reaching a lethal dose?

A student is preparing a solution of sucrose at a specific concentration. They are doing this by weighing out sucrose on a scale, placing it in a volumetric flask, dissolving it in water, and then diluting it up to the mark on the volumetric flask with water. How would the experimental (actual) molar concentration for C12H22O11 differ from the calculated concentration ( higher, lower, or the same) given the following scenarios? Explain.

a) Lysine is an essential amino acid. It is taken by some people as a nutritional supplement in the form of a hydrated crystalline solid with the formula C6H₁4N2O2.XH₂O . To control the dose of lysine, it is essential to know the complete formula of the hydrate, which means determining the value of x. To determine the value of x in lysine hydrate, a pharmacist used a direct titration method. She dissolved 6.258g of the compound in approximately 100mL of distilled water and then made this up to 250mL in a volumetric flask. She then titrated 25mL aliquots of this solution with a standardized NaOH solution of concentration 0.1050 mol dm-³, obtaining a mean titre of 36.30 mL. In titrations, lysine behaves as a monoprotic acid. Use these data to determine the value of x in lysine hydrate. b) In a second experiment to verify the value of x, the pharmacist heated a 3.752g sample of the lysine hydrate to drive off all the water. When she reweighed the sample, the mass was 3.278 g. Use this…

A phlebotomist gets a needlestick from a patient with known hepatitis B viral infection. The best immunoassay test to detect newly acquired disease in the phlebotomist is to measure the hepatitis B surface antigen within the first 3 months of the encounter.   Question 3 options:   True   False

Can you identify the acceptable exposure limits for affected populations in occupational and nonoccupational environments?

2. Which of the following statements is FALSE regarding the log-kill hypothesis? a. It predicts the 100% eradication of cells after some period of time. b. It is an application of first-order kinetics. c. It predicts that cell counts decrease exponentially with repeated cycles of application. d. It applies to sterilization as well as other fields such as chemotherapy. e. Each cycle of application kills the same fraction (or %) of cells just prior to that cycle.
