Question 1 of 5
When a company develops a new drug and gives it an official name, this name is the _____.
Correct Answer: A
Rationale: When a company develops a new drug and gives it an official name, this name is the brand name. The brand name is the unique name that the company chooses to market the drug under, often for trademark purposes. It is typically a more catchy and recognizable name compared to the generic name of the drug, which is based on the drug's active ingredients. The brand name is used for marketing and promoting the drug to consumers and healthcare professionals. Examples of brand names include Advil, Tylenol, and Viagra.

Question 3 of 5
What is the primary action of interferon alfa?
Correct Answer: C
Rationale: Interferon alfa is an immunomodulatory agent that works by enhancing the immune system's ability to fight cancer. It has cytotoxic and cytostatic effects, meaning it can kill cancer cells or inhibit their growth. Additionally, it promotes the differentiation of stem cells, which can help restore normal cell function. While interferon alfa does produce cytokines and interleukins, its primary action is immunomodulation and direct effects on cancer cells. It does not primarily cause allergic reactions or produce red blood cells.
Question 4 of 5
A 24-year-old sexually active woman presents to her primary care physician with vaginal itching and a greenish, frothy vaginal discharge. Her boyfriend is asymptomatic. She is prescribed metronidazole for Trichomonas vaginalis. Which of the following should be told to avoid while taking metronidazole?
Correct Answer: A
Rationale: Metronidazole treats Trichomonas vaginalis, and alcohol must be avoided. It inhibits aldehyde dehydrogenase, causing a disulfiram-like reaction (nausea, flushing). Aspirin , caffeine , grapefruit juice , and machinery (E) lack this interaction. This precaution prevents severe discomfort, ensuring treatment adherence.
Question 5 of 5
All are specialized transports. except:
Correct Answer: D
Rationale: Simple diffusion is a passive transport process that does not require specialized transport proteins or energy expenditure. It involves the movement of molecules from an area of higher concentration to an area of lower concentration without the aid of a protein channel or carrier. In contrast, active transport, facilitated diffusion, and pinocytosis are specialized transports that utilize specific proteins and mechanisms to help move molecules across cell membranes. Active transport requires energy to move molecules against their concentration gradient, facilitated diffusion involves the use of specific protein channels or carriers to facilitate movement, and pinocytosis is a form of endocytosis where cells engulf fluid droplets.
