In response to the patient's question about how to know whether drugs are safe, the nurse explains that all medications undergo rigorous scientific testing controlled by what organization?

A. While medication adherence is important, the primary reason for asking about alternative therapies is not due to concerns about compliance. Patients may use alternative therapies alongside prescribed medications, potentially leading to harmful interactions.

B. Many complementary and alternative therapies, such as herbal supplements, can interact with prescribed medications, leading to adverse effects or reduced drug efficacy. For example, St. John’s Wort can decrease the effectiveness of certain medications, including anticoagulants and antidepressants. Identifying these therapies ensures patient safety.

C. While some natural products may have therapeutic benefits, they are not necessarily more effective than prescribed medications. Healthcare providers should base treatment decisions on evidence-based practice rather than assuming an alternative therapy is superior.

D. Financial concerns are important but not the primary reason for inquiring about alternative therapies. The nurse’s main concern is the potential for harmful drug interactions rather than the cost burden on the patient.

a) Encouraging self-application is beneficial in some cases, but it is not always appropriate. The nurse must ensure the medication is applied correctly and safely, especially if the patient has mobility or cognitive impairments.

b) Wearing treatment gloves is important when handling certain medications, but it is not required for all topical applications. Some medications, such as nitroglycerin ointment, require gloves to prevent nurse exposure, but others do not.

c) Changing gloves between skin preparation and medication application is not a universal requirement. In most cases, the same pair of gloves can be used unless contamination occurs.

d) Performing effective hand hygiene before and after applying the medication is the most essential action to prevent infection and cross-contamination.
