Correct Answer: C

Rationale: The correct answer is C. Erythromycin should be taken on an empty stomach with a full glass of water to increase absorption. Taking it with a full glass of milk (Choice A) is incorrect. Avoiding direct sunlight (Choice B) is not related to erythromycin use. Taking an antacid before the medication (Choice D) can interfere with its absorption.

Correct Answer: B

Rationale: Pressing on the nasolacrimal duct, located near the inner corner of the eye, blocks the lacrimal punctum and prevents the medication from entering the systemic circulation. This technique helps to ensure the medication stays localized in the eye, enhancing its therapeutic effect while minimizing systemic side effects.

Correct Answer: B

Rationale: The correct answer is to avoid foods high in vitamin K. Vitamin K can interfere with the effectiveness of Warfarin by counteracting its anticoagulant effects. Foods high in vitamin K, such as leafy green vegetables, should be limited in the diet of individuals taking Warfarin to maintain a consistent level of the medication's effectiveness.

Correct Answer: B

Rationale: The correct answer is to instruct the client to remain upright for 30 minutes after taking Alendronate. This medication can cause esophageal irritation, and maintaining an upright position for at least 30 minutes helps prevent complications such as esophagitis or esophageal ulcers.

Correct Answer: D

Rationale: Oxybutynin is an anticholinergic medication that can increase intraocular pressure. It is contraindicated in clients with glaucoma, as it can worsen the condition. Glaucoma is a condition characterized by increased intraocular pressure, and using Oxybutynin can further elevate this pressure, potentially leading to serious complications such as vision impairment or damage to the optic nerve.
