Final answer:
Cardiac monitoring is recommended when caring for a patient with an eye-related emergency because ocular pressure can stimulate the vagus nerve and cause bradycardia. Blocked fluid circulation in the eye can lead to glaucoma, which can affect the heart rate. Eye drops or medication used for eye emergencies may also cause an elevation in heart rate.
Step-by-step explanation:
Cardiac monitoring is recommended when caring for a patient with an eye-related emergency because the ocular pressure can stimulate the vagus nerve and cause bradycardia. When the circulation of fluid in the eye is blocked, it can lead to glaucoma, which can result in an increase in intraocular pressure and potentially affect the heart rate. In certain cases, eye drops or medication used to treat eye emergencies can also cause a marked elevation in heart rate.
