A nurse is preparing to administer an ophthalmic medication to a client.
Which of the following actions should the nurse plan to take?
Instill the ophthalmic medication directly on the client's cornea.
Ask the client to tightly squeeze their eyes shut after the instillation.
Clean the client's eye from the outer canthus to the inner canthus before instillation.
Apply pressure to the client's nasolacrimal duct after instillation.
The Correct Answer is D
Choice A rationale
Instilling ophthalmic medication directly on the cornea can cause irritation and discomfort. Medications should be administered in the conjunctival sac.
Choice B rationale
Asking the client to tightly squeeze their eyes shut after instillation can expel the medication, reducing its effectiveness. Gentle closing of the eyes is recommended.
Choice C rationale
Cleaning the eye from the outer canthus to the inner canthus is not the proper method. The correct method is to clean from the inner canthus to the outer canthus to avoid contaminating the inner eye.
Choice D rationale
Applying pressure to the nasolacrimal duct after instillation helps prevent the medication from draining into the nasolacrimal system, ensuring better absorption in the eye.

Correct Answer is C
Explanation
Choice A rationale
Cheese is high in calcium, which can interfere with the absorption of iron by binding to it in the digestive tract, making it less available for absorption.
Choice B rationale
Antacids containing magnesium can interfere with the absorption of iron by increasing the pH of the stomach, reducing the solubility and absorption of iron.
Choice C rationale
Orange juice is high in vitamin C, which can enhance the absorption of iron by reducing it to a form that is more easily absorbed by the body.
Choice D rationale
Milk contains calcium, which can inhibit the absorption of iron. Calcium competes with iron for absorption in the intestines, leading to reduced iron absorption.
Correct Answer is D
Explanation
Choice A rationale
Collecting two stool specimens from the same area of the stool is incorrect because specimens should be taken from different areas to ensure a representative sample of the stool for testing.
Choice B rationale
Using toilet paper to transfer the stool specimen is not recommended as it can contaminate the sample and interfere with test results.
Choice C rationale
Applying four drops of developing solution to each stool specimen is incorrect. The usual procedure involves applying a specific number of drops as indicated by the test instructions, which may vary.
Choice D rationale
Waiting 30 seconds after applying the developing solution is correct. This waiting period allows the test to react and provide accurate results for the presence of occult blood.
