When expressing metric dosages where the number is less than one (a decimal fraction), the health care provider should:
a. Convert the decimal to the next greater value to avoid having a number smaller than one
b. Ensure that the decimal point is at the start of the equation and no numbers precede it to avoid confusion
c. Ensure that a 0 precedes the decimal to draw attention to the decimal
d. Change the equation to a common fraction avoiding the use of a decimal
c
Rationale: c. "When the number is less than one (a decimal fraction), a "0" is written before the decimal point. This leading "0" is especially important in medication calculations because it draws attention to the decimal point and prevents medication dosage errors.".

Serum vitamin B12 is highly unstable when exposed to light and can tolerate only a single absorbance reading before breaking down. Therefore, it is not possible to generate a standard curve for B12. When the concentration of B12 must be ascertained in a p
A) Calculate the concentration of B12 directly from its absorbance in the solution using Beer's Law. B) Determine the Km and Vmax of B12 and apply those values to Ohm's Law to calculate the concentration of B12. C) Generate a standard curve using a more stable vitamin of similar chemical structure. D) Measure transmittance of B12 and create a standard curve using transmittance against concentration.
