A nurse is reinforcing teaching with a client about how to perform a breast self exam (BSE). The nurse should identify which of the following findings as an indication of breast cancer?

Choice A reason: This is an incorrect action, because instructing the client to blink several times after instillation of the medication can cause the medication to drain out of the eye and reduce its effectiveness.

Choice B reason: This is a correct action, but not the best one. Asking the client to look straight ahead during instillation of the medication can help the nurse to aim the drop accurately and avoid touching the eye with the dropper.

Choice C reason: This is the best action, because applying pressure to the bridge of the nose after instillation of the medication can prevent the medication from entering the systemic circulation and causing adverse effects, such as bradycardia, hypotension, or bronchospasm.

Choice D reason: This is an incorrect action, because placing each drop of the medication directly on to the client's cornea can cause irritation, injury, or infection to the eye. The medication should be placed in the lower conjunctival sac of the eye.

Choice A reason: This is an incorrect statement, because the client should avoid any body piercings, tattoos, or other procedures that can cause skin or mucosal trauma and increase the risk of bacterial infection and endocarditis. The client should also seek medical attention if they have a fever or other signs of infection.

Choice B reason: This is a correct statement, because the client should notify their doctor before they have dental procedures, such as cleaning, filling, or extraction, that can cause bleeding and introduce bacteria into the bloodstream. The client may need prophylactic antibiotics to prevent endocarditis.

Choice C reason: This is a partially correct statement, because the client should floss their teeth twice a day as a part of their oral care, but this is not enough to prevent recurrence of endocarditis. The client should also brush their teeth with a soft toothbrush after each meal, use an antiseptic mouthwash, and visit their dentist regularly.

Choice D reason: This is an unnecessary statement, because the client does not need to wear a mask when they go out in public, unless they have a respiratory infection or are exposed to someone who has one. Endocarditis is not transmitted by airborne or droplet routes, but by direct contact with the infected heart valves or blood.
