An important concept taught by the nurse when providing medication teaching is the need to provide a complete list of medications taken to health care providers to avoid what?
- A. Spending large amounts of money on medications
- B. Allergic reactions to medications
- C. Drug-drug interactions
- D. Critical concentrations of medications in the body
Correct Answer: C
Rationale: It is important that all health care providers have a complete list of the patients medications to avoid drug-drug interactions caused by one provider ordering a medication, unaware of another medication the patient is taking that could interact with the new prescription. Using the same pharmacist for all prescriptions will also help to prevent this from happening. Informing the provider of all medications taken will not reduce costs of medications, which is best accomplished by requesting generic medications. Allergies should be disclosed to all health care providers as well, but this is not why it is important to provide a complete list of medications taken. Critical concentrations are desirable because that is the amount of drug needed to cause a therapeutic effect, or, in other words, to have the effect the drug is prescribed for.
