Maintaining skin integrity would include:

Choice A: Sepsis is a serious infection that occurs when the body's immune system overreacts to an injury or illness. It can cause organ failure and death. People with spinal cord injury are more prone to sepsis because they may have impaired bladder and bowel function, skin breakdown, or reduced sensation that can lead to infections.

Choice B: Pulmonary embolism is a blockage of an artery in the lungs by a blood clot. It can cause chest pain, shortness of breath, and death. People with spinal cord injury are more at risk of pulmonary embolism because they may have reduced mobility, blood circulation, or breathing capacity that can promote blood clot formation.

Choice C: Pneumonia is an inflammation of the lungs caused by bacteria, viruses, or fungi. It can cause fever, cough, and difficulty breathing. People with spinal cord injury are more susceptible to pneumonia because they may have weakened cough reflex, impaired lung function, or aspiration of food or saliva into the lungs.

Choice D: All of the above are major causes of death related to spinal cord injury. They can occur separately or together and can be prevented or treated with proper medical care and lifestyle modifications.

Choice A: Encouraging lots of visitors is incorrect because it can increase the stimulation, stress, and noise level for the patient with a hemorrhagic stroke. A hemorrhagic stroke occurs when a blood vessel in the brain ruptures and bleeds into the surrounding tissue. This can cause increased intracranial pressure, brain damage, or death. The patient needs to rest and avoid any factors that can raise their blood pressure or worsen their condition.

Choice B: Out of bed with lots of walking in the halls is incorrect because it can also increase the risk of complications for the patient with a hemorrhagic stroke. The patient may have impaired mobility, balance, or coordination due to the brain injury. They may also have weakness, numbness, or paralysis on one side of the body. The patient needs to be assessed and assisted with their activity level and safety precautions.

Choice C: Nonstimulating, nonstressful environment; dim lighting, visitors are restricted is correct because it can help reduce the intracranial pressure and promote healing for the patient with a hemorrhagic stroke. The patient needs to have a quiet, calm, and comfortable environment that minimizes sensory input and emotional distress. The patient also needs to have limited and supervised visitors who are supportive and respectful of their needs.

Choice D: All of the above are incorrect because only choice c) is appropriate for the patient with a hemorrhagic stroke. Choices a) and b) are contraindicated and can harm or hinder the patient's recovery. The nurse should provide individualized and evidence-based care for the patient with a hemorrhagic stroke and follow the guidelines and protocols for stroke management.
