A nurse is instructing a newly licensed nurse about age-related changes to vision in older adult patients.
Which of the following should the nurse include as an example of an expected age-related change?

Choice A rationale
Academic pressure is a psychological stressor, not a physiological one. It involves mental or emotional strain or tension resulting from adverse or demanding circumstances, in this case, related to academic performance.
Choice B rationale
A burn injury is an example of a physiological stressor. Physiological stressors are related to physical or biological factors that strain the body’s resources. A burn injury places physical stress on the body as it tries to heal and recover.
Choice C rationale
Financial difficulties are a type of environmental stressor, not a physiological one. They involve external factors in a person’s environment that cause stress, such as financial problems or jobrelated stress.
Choice D rationale
A change in marital status is a type of psychosocial stressor, not a physiological one. It involves both psychological factors (such as emotions and behavior) and social factors (such as relationships and social interactions).

Choice A rationale
Carbonic anhydrase inhibitors are not typically the first line of treatment for glaucoma. They work by decreasing the production of eye fluid, but they are usually used when other treatments have not been successful. Choice B rationale
Prostaglandin analogs, such as latanoprost and travoprost, are often the first line of treatment for glaucoma. They work by increasing the outflow of eye fluid to lower pressure in the eye.
Choice C rationale
Alpha-agonists are not typically the first line of treatment for glaucoma. They work by both decreasing the production of eye fluid and increasing its outflow, but they are usually used when other treatments have not been successful.
Choice D rationale
Beta-blockers, like timolol, are sometimes used as initial treatment for glaucoma, but they are not typically the preferred initial medication. They work by reducing the production of eye fluid.
