A nurse is preparing to administer timolol eye drops for a client who has glaucoma. When instilling the medication, which of the following actions should the nurse take?
Instruct the client to blink several times after instillation of the medication.
Ask the client to look straight ahead during instillation of the medication.
Apply pressure to the bridge of the nose after instillation of the medication.
Place each drop of the medication directly on to the client's cornea.
The Correct Answer is C
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.

Correct Answer is B
Explanation
Choice A reason: This is an incorrect statement, because the client should not share razors with anyone, even if they are disposable. Razors can cause cuts and bleeding, which can transmit the HIV virus and other infections. The client should use their own personal hygiene items and dispose of them safely.
Choice B reason: This is the correct statement, because the client should clean bathroom surfaces with a bleach and water solution. Bleach is a disinfectant that can kill germs and prevent the spread of infections. The client should also wash their hands frequently and avoid contact with bodily fluids.
Choice C reason: This is an incorrect statement, because the client should not increase their intake of raw fruits and vegetables. Raw fruits and vegetables can contain bacteria, parasites, or pesticides, which can cause infections and complications in the client who has a weakened immune system. The client should wash and cook their fruits and vegetables thoroughly before eating them.
Choice D reason: This is an incorrect statement, because the client should not continue their hobby of gardening, even if they wear a mask. Gardening can expose the client to soil, dust, fungi, or insects, which can cause infections and allergies in the client who has a compromised immune system. The client should avoid activities that can increase their risk of infection.
Correct Answer is B
Explanation
Choice A reason: This is an incorrect route, because maternal-fetal transmission of hepatitis A is very rare and occurs only if the mother has acute hepatitis A during the third trimester of pregnancy.
Choice B reason: This is the correct route, because fecal-oral contamination of hepatitis A is the most common mode of transmission. Hepatitis A is a viral infection that affects the liver and is spread through ingestion of contaminated food or water, or contact with infected feces.
Choice C reason: This is an incorrect route, because genital sexual contact of hepatitis A is uncommon and occurs only if there is oral-anal contact with an infected person.
Choice D reason: This is an incorrect route, because blood to blood transmission of hepatitis A is also uncommon and occurs only if there is exposure to infected blood or blood products, such as through needle sharing or transfusion.
