The nurse is assessing a patient’s visual acuity using a Snellen chart. The patient states he cannot see the top of the chart.
What action should the nurse take?

Choice A rationale

Venous thromboembolism (VTE) is a serious complication that can occur in comatose patients. Immobility is a major risk factor for VTE, and comatose patients are often immobile. Therefore, nurses should be vigilant for signs of VTE, such as swelling, pain, or redness in the extremities.
Choice B rationale
Hemorrhage is not typically a direct complication of coma. However, the underlying cause of the coma, such as a traumatic brain injury, could potentially lead to hemorrhage.
Choice C rationale
Contractures, or the shortening and hardening of muscles, tendons, or other tissue, can occur in comatose patients due to prolonged immobility. Regular movement and physiotherapy can help prevent this complication.
Choice D rationale
Pressure ulcers, also known as bedsores, are a common complication in comatose patients. They occur when there is prolonged pressure on the skin, usually over bony areas. Regular turning and good skin care can help prevent pressure ulcers.
Choice E rationale
Pneumonia is a common complication in comatose patients, often resulting from aspiration (inhaling food, stomach acid, or saliva into the lungs)2. Nurses should be vigilant for signs of pneumonia, such as fever, cough, and difficulty breathing.

Choice A rationale
While participation in multiple-step activities can provide mental stimulation, it may be challenging for a patient with Alzheimer’s disease. These activities often require a level of cognitive functioning that may be impaired in Alzheimer’s patients. As a result, these activities could lead to frustration and agitation rather than fostering socialization.
Choice B rationale
Hobbies involving fine motor skills can be beneficial for maintaining dexterity and coordination. However, as Alzheimer’s disease progresses, these skills often decline. Therefore, while these hobbies may be enjoyable, they may not necessarily foster socialization.
Choice C rationale
Limiting visitors to one or two at a time can help to prevent overstimulation, which can be distressing for a person with Alzheimer’s disease. Smaller, more intimate gatherings can also foster more meaningful social interactions. Therefore, this approach can be beneficial for promoting socialization.
Choice D rationale
While social interaction is important for people with Alzheimer’s disease, frequent lengthy visits from friends may be overwhelming and lead to fatigue. It’s important to balance socialization with rest and relaxation. Therefore, promoting frequent lengthy visits may not be the best approach to foster socialization.
