A patient with Bell's palsy asks the nurse why they have to wear an eye shield at night. What would be the nurse's best response?
A) "A patient with Bell's palsy often can't close his or her eye, which causes insomnia."
B) "A patient with Bell's palsy needs an eye shield at night to prevent injury to the eye."
C) "A patient with Bell's palsy can't blink, so the eye shield keeps the eye moist."
D) "A patient with Bell's palsy needs extra coverage for his or her eye."
Ans: B
Feedback: While the paralysis lasts, nursing care involves protection of the eye from injury. Frequently, the eye does not close completely and the blink reflex is diminished, so the eye is vulnerable to injury from dust and foreign particles. Corneal irritation and ulceration may occur. Distortion of the lower lid alters the proper drainage of tears. To prevent injury, the eye should be covered with a protective shield at night. Options A and C are incorrect because they give the patient misinformation. Option D is incorrect because it does not answer the question.
