What aspect of pharmacology does a nurse study? (Select one that does not apply.)
- A. Adverse and anticipated drug effects
- B. Molecular pharmacology
- C. Impact of drugs on the body
- D. The bodys response to a drug
Correct Answer: B
Rationale: Nurses study pharmacology from a pharmacotherapeutic level, which includes the effect of drugs on the body, the bodys response to drugs, and both expected and unexpected drug effects. Chemical and molecular pharmacology (Options A and B) are not included in nursing pharmacology courses. Adverse and anticipated drug effects are part of pharmacotherapeutics, making C, D, and E correct.

A nurse is caring for a patient who has been receiving a drug by the intramuscular route but will receive the drug orally after discharge. How does the nurse explain the increased dosage prescribed for the oral dose?
- A. Passive diffusion
- B. Active transport
- C. Glomerular filtration
- D. First-pass effect
Correct Answer: D
Rationale: The first-pass effect involves drugs that are absorbed from the small intestine directly into the portal venous system, which delivers the drug molecules to the liver. After reaching the liver, enzymes break the drug into metabolites, which may become active or may be deactivated and readily excreted from the body. A large percentage of the oral dose is usually destroyed and never reaches tissues. Oral dosages account for the phenomenon to ensure an appropriate amount of the drug in the body to produce a therapeutic action. Passive diffusion is the major process through which drugs are absorbed into the body. Active transport is a process that uses energy to actively move a molecule across a cell membrane and is often involved in drug excretion in the kidney. Glomerular filtration is the passage of water and water-soluble components from the plasma into the renal tubule.
