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) Applying the medication liberally is incorrect because the amount of medication applied should be based on the prescribed dose. Overapplication can lead to excessive absorption and potential systemic effects.

b) Cleaning the skin with alcohol before applying the medication is not always necessary and can cause irritation. Some medications require specific preparation, but alcohol is not a universal requirement.

c) Using sterile technique is generally unnecessary for topical medication application unless the skin is broken or there is an open wound requiring sterility.

d) Wearing gloves is essential to prevent medication absorption through the nurse’s skin and to reduce the risk of contamination or infection.
