Rationale: When the client presses on the nasolacrimal duct while instilling eye drops, it temporarily blocks the lacrimal punctum. This obstruction helps prevent the systemic absorption of the medication by minimizing drainage into the nasolacrimal duct and subsequent systemic circulation. By following this technique, the client can enhance the localized effect of the eye drops and reduce the risk of systemic side effects.

Correct Answer: B

Rationale: The nurse should withhold the medication and inform the provider of the client's previous rash after taking penicillin. This history suggests a potential allergic reaction to penicillin, which can range from mild to severe anaphylaxis. Notifying the provider allows for an alternative antibiotic to be prescribed, considering the client's allergy to penicillin. It is crucial to avoid administering a medication that could potentially lead to a severe allergic reaction in the client.

Therefore, the nurse should instruct the client to avoid using St. John's wort while taking Warfarin to prevent adverse drug interactions. Additionally, it is essential to educate the client about other herbal supplements like garlic and ginseng, which may also interact with Warfarin and should be avoided to ensure the medication's efficacy and safety.
