A client is brought into the emergency room with sudden severe complaints of eye pain, blurred and decreased visual acuity, and extreme pressure in their eyes. The nurse would most likely suspect the client to have:

Choice A reason: The statement "I can change who serves as my health care proxy at any time" is correct. A client can modify or revoke their health care proxy designation as long as they are mentally competent.

Choice B reason: The statement "The health care proxy does not go into effect until I am incapable of making decisions" is accurate. The health care proxy is activated when the client is unable to make their own medical decisions.

Choice C reason: The statement "I have to choose a family member as my health proxy" indicates a need for clarification. A client is not required to choose a family member as their health care proxy; they can select any trusted individual to act in this capacity.

Choice D reason: The statement "My health care proxy can make decisions on my behalf if I am unable to do so" is correct. The purpose of a health care proxy is to appoint someone to make medical decisions when the client is incapacitated.

Choice A reason: Atropine is an anticholinergic medication that blocks the effects of the parasympathetic nervous system. One of its effects is relaxation of the smooth muscles in the bladder, which can lead to urinary retention. This occurs because the bladder's ability to contract is inhibited, making it difficult for the patient to void.

Choice B reason: Bradycardia is not an expected effect of atropine. In fact, atropine is often used to treat bradycardia by increasing heart rate. It works by blocking the vagus nerve's influence on the heart, which normally acts to slow the heart rate. Therefore, atropine would be expected to cause an increase in heart rate, not a decrease.

Choice C reason: Diarrhea is not a common effect of atropine. Atropine works by reducing the activity of the gastrointestinal tract, leading to a decrease in bowel movements and potentially causing constipation rather than diarrhea. Anticholinergic drugs like atropine reduce gastrointestinal motility, which can lead to a slower passage of food through the intestines.

Choice D reason: Vomiting is not typically associated with the administration of atropine. While nausea and vomiting can be side effects of many medications, atropine more commonly causes dry mouth, blurred vision, and constipation. The medication's action on the gastrointestinal tract tends to slow digestive processes rather than stimulate vomiting.
