Example Of Pharmacy Questions Essay

Question one

A diluent is an ingredient used in medical preparation that has no pharmacological activity but is desirable. Such an ingredient takes various forms, can be liquid or solid and, therefore, the application of the diluent depends on its form For example in capsules, it can either be starch or lactose. The diluent is used to increase the bulk of the drugs that are too small for administration or manufacture. Liquid diluents are used to dissolve drugs before injecting, inhaling, or injecting (UNC, n.d). To know the quantity of diluent to use, the nurses needs to check the package of each drug. The packages contain the directions for reconstitution the drug as well as the storage (“Dosage Calculations Packet,” n.d.). The instructions include the amount of diluent one can use to make specific doses. In the event, that there are no clear labels on the package of the drugs, the nurse may refer to the manual available in the pharmacy.

Question two

The parietal cell found in the oxyntic glands is responsible for the secretion of hydrochloric acid. The parietals cell are mainly found in the lower sections the oxyntic cells occupying about two-thirds of tis surface. The parietal cells produce acid depending on food ingestion. Gastroesophageal reflux diseases occur when three substances (histamine, gastrin, and acetylcholine gets into the parietal cells through different mechanism. These substances trigger the production of hydrochloric acid (gastric acid) by activation of the H+K+. When the acid accumulate for long leading to the pH value of less than four (pH<4), severe GERD develops. Since parietal cells produce acid, it is, therefore, evident that they play a direct role in the formation of GERD.
