The student nurse asks the nursing instructor why he needs to take anatomy and physiology, as well as microbiology, when he only wants to learn about pharmacology. What is the best response by the instructor?
1. "Because pharmacology is an outgrowth of those subjects."
2. "You must learn all, since those subjects, as well as pharmacology, are part of the curriculum."
3. "Knowledge of all those subjects will prepare you to provide the best patient care, including the administration of medications."
4. "Because an understanding of those subjects is essential to understanding pharmacology."
Correct Answer: 4
Rationale: It is essential for the nurse to have a broad knowledge base of many sciences in order to learn pharmacology. The nurse must learn anatomy, physiology, and microbiology to understand pharmacology, not because they are part of the curriculum. Pharmacology is an outgrowth of anatomy, physiology, and microbiology, but this is not the reason for the nurse to learn them. Knowledge of anatomy, physiology, and microbiology prepares the nurse to understand pharmacology, not to provide care such as administration of medications.
