Final answer:
In the case of an eye injury, one should avoid placing drops or opening a swollen eye, and seek medical attention where an eye care professional can manage the injury and prevent complications like glaucoma.
Step-by-step explanation:
Assessment and care guidelines for a patient with an eye injury should include options such as bandaging both eyes to prevent movement or covering the injured eye with a protective shield and seeking immediate medical attention. Introducing foreign substances like drops could exacerbate the injury, and medical professionals should make assessments regarding anything by mouth, as the patient may need to undergo surgery. Forcefully opening a swollen-shut eye is not recommended due to the risk of causing further damage. Therefore, neither option B nor D is recommended. Providing proper care and avoiding additional injury are crucial components of eye injury management to avoid complications like excessive intraocular pressure which can lead to glaucoma.
