A nurse is assessing the patients home medication use. After listening to the patient list current medications, the nurse asks what priority question?
- A. Do you take any generic medications?
- B. Are any of these medications orphan drugs?
- C. Are these medications safe to take during pregnancy?
- D. Do you take any over-the-counter medications?
Correct Answer: D
Rationale: It is important for the nurse to specifically question use of over-the-counter medications because patients may not consider them important. The patient is unlikely to know the meaning of orphan drugs unless they too are health care providers. Safety during pregnancy, use of a generic medication, or classification of orphan drugs are things the patient would be unable to answer but could be found in reference books if the nurse wishes to research them.
