A nurse is caring for a client who has a subarachnoid hemorrhage and asks why they are having a CT angiography. Which of the following should the nurse understand about CT angiography?
A CT angiogram will reveal any edema within the brain tissue.
A CT angiogram will reveal any overproduction of cerebrospinal fluid (CSF).
A CT angiogram will reveal any fractures within the skull or spine.
A CT angiogram will reveal any decreased blood flow related to vasospasm.
The Correct Answer is D
A. A CT angiogram will reveal any edema within the brain tissue: CT angiography primarily focuses on visualizing blood vessels and blood flow within the brain. While it may incidentally detect areas of edema, its primary purpose is to assess vascular structures rather than brain tissue changes such as edema.
B. A CT angiogram will reveal any overproduction of cerebrospinal fluid (CSF): CT angiography does not assess cerebrospinal fluid (CSF) production. Its main function is to visualize blood vessels and blood flow within the brain, particularly to detect abnormalities such as aneurysms, arteriovenous malformations, or vasospasm.
C. A CT angiogram will reveal any fractures within the skull or spine: CT angiography primarily focuses on imaging blood vessels and is not the preferred modality for detecting fractures within the skull or spine. CT scans or plain radiography are typically used to assess bony structures for fractures.
D. A CT angiogram will reveal any decreased blood flow related to vasospasm: This statement is correct. CT angiography is a specialized imaging technique that combines computed tomography (CT) scanning with contrast dye to visualize blood vessels and blood flow within the brain. It is commonly used to detect and monitor vasospasm, a potentially serious complication of subarachnoid hemorrhage, where blood vessels in the brain constrict, leading to decreased blood flow. CT angiography allows for the visualization of these changes in blood vessel diameter and blood flow dynamics.

Correct Answer is D
Explanation
A. Comply with compression therapy: Compression therapy is commonly used in the management of peripheral vascular disease (PVD), not valvular heart disease. It involves applying external pressure to the limbs to improve circulation and reduce edema. While this intervention may be relevant for a client with PVD, it is not specific to valvular heart disease.
B. Monitor wounds on lower extremities: Monitoring wounds on lower extremities is important for clients with peripheral vascular disease (PVD) to assess for signs of poor wound healing, infection, or tissue ischemia. However, it is not directly related to valvular heart disease. Therefore, while wound monitoring may be appropriate for this client, it is not specific to valvular heart disease education.
C. Take antiplatelet medications as ordered: Antiplatelet medications, such as aspirin or clopidogrel, are commonly prescribed for clients with peripheral vascular disease (PVD) to reduce the risk of thrombotic events and improve blood flow. However, they are not typically indicated as a primary treatment for valvular heart disease. While some clients with valvular heart disease may have comorbidities that warrant antiplatelet therapy, it is not specific to valvular heart disease education.
D. Valvular heart disease involves dysfunction of one or more heart valves, leading to impaired blood flow within the heart. The nurse should educate the client on monitoring for the gradual onset of symptoms related to valvular heart disease. These symptoms may include dyspnea (shortness of breath), fatigue, palpitations, chest discomfort, and edema. Monitoring for these symptoms allows for early detection of disease progression or exacerbation, prompting timely intervention and management.
Correct Answer is A
Explanation
A. "I need to walk slowly as I lose my balance often": This statement indicates a potential safety concern related to balance issues while walking. Loss of balance can increase the risk of falls, especially in individuals with peripheral artery disease (PAD) who may already have compromised circulation and reduced sensation in their legs. The nurse should report this statement to the provider for further evaluation and intervention to prevent falls and promote safety.
B. "I don't go out much because of the pain in my legs" : While this statement suggests that the client experiences pain in their legs, it does not directly indicate a safety concern that requires immediate reporting to the provider. Pain management strategies may be discussed with the provider to address this issue.
C. "It makes me sad that I can't keep up with my grandchildren" : While this statement reflects emotional distress related to the client's inability to participate fully in activities with their grandchildren, it does not indicate a specific safety concern that requires reporting to the provider. However, addressing the client's emotional well-being is important for overall holistic care.
D. "I have a small-healed area on my spine that is painful" : This statement describes a painful area on the client's spine but does not directly relate to potential safety concerns associated with PAD. The nurse may further assess this issue and include it in the client's overall assessment, but it does not require immediate reporting to the provider for safety concerns related to PAD.
