A home health nurse is teaching an older adult client who just had cataract surgery. Which of the following instructions should the nurse include?

Choice A reason: This is incorrect because slow cautious behaviors are more consistent with a stroke involving the right hemisphere. The right hemisphere controls spatial awareness, creativity, and intuition. A stroke affecting this hemisphere can cause impulsivity, poor judgment, and denial of deficits.

Choice B reason: This is incorrect because loss of depth perception is more consistent with a stroke involving
the right hemisphere. The right hemisphere controls visual-spatial perception, which includes depth perception, distance estimation, and object recognition. A stroke affecting this hemisphere can cause difficulty in navigating space, judging distances, and identifying objects.

Choice C reason: This is incorrect because the overestimation of abilities is more consistent with a stroke involving
the right hemisphere. The right hemisphere controls emotional regulation, self-awareness, and insight. A stroke affecting this hemisphere can cause euphoria, lack of insight, and unrealistic expectations.

Choice D reason: This is the correct answer because hemianopsia is consistent with a stroke involving
the left hemisphere. The left hemisphere controls language, logic, and analysis. A stroke affecting this hemisphere can cause hemianopsia, which is the loss of vision in half of the visual field. This can affect reading, writing, and communication skills.

Choice A Reason: Seasonal allergies are not a cause of delirium, but a common condition that affects the respiratory system and causes symptoms such as sneezing, runny nose, itchy eyes, or coughing.

Choice B Reason: History of GERD is not a cause of delirium, but a chronic condition that affects the digestive system and causes symptoms such as heartburn, regurgitation, chest pain, or difficulty swallowing.

Choice C Reason: Benzodiazepines are a cause of delirium, especially in older adults or those with cognitive impairment. Benzodiazepines are a class of drugs that act on the central nervous system and cause sedation, relaxation, and reduced anxiety. However, they can also impair memory, attention, orientation, and judgment, and lead to confusion, agitation, hallucinations, or delusions.

Choice D Reason: Completed antibiotics 10 days ago are not a cause of delirium, but a treatment for bacterial infections. Antibiotics can have side effects such as nausea, diarrhea, rash, or allergic reactions, but they do not cause delirium unless they are toxic or interact with other medications.
