Our pharmacy is located near several pediatricians’ offices, and each of these pediatricians has a preferred mouth rinse for sore throat. One doctor writes a combination of lidocaine, antacid, and Benadryl for a sore throat. Depending on the cause of the sore throat, she may add nystatin, an antifungal medication, or acyclovir, an antiviral medication. A typical prescription will read: antacid 1 part, lidocaine 2 parts, Benadryl 1 part, and nystatin 4 parts; dispense 8 ounces. We have found one of the simplest ways to calculate the amount of each drug to mix is by using fractions. First we add up the total number of “parts,” and this becomes our denominator or bottom number. For this compound, the denominator is 1 + 2 + 1 + 4 = 8. The numerator or top number is how many parts of that ingredient are used. For example, two parts of the mixture are lidocaine, so lidocaine is 2/8 of the mixture. To calculate how many ounces of lidocaine are needed, the fraction is multiplied by the total…

Bone marrow is a soft, spongy, connective tissue found inside bones. Bone marrow contains stem cells, which can generate new blood cells and, therefore, can treat many diseases of the blood. In the past, extracting bone marrow from a donor required anesthesia and a long, large needle. The process often discouraged people from signing up to be donors. A process called apheresis has made the process much less painful and invasive. In apheresis, the donor's blood passes through a sterile line into the machine. Once the blood is inside the machine, the bone marrow stem cells are extracted, and the remaining blood is returned to the donor. Donors typically only experience minor discomfort from the needles used and the loss of electrolytes. Describe how you think this advance in biotechnology will affect individuals and society. Be sure to include any potential medical or ethical issues that could arise from this new practice.
