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.

Answer and Explanation

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 B

Explanation

A. "You can have 2 to 3 cups of coffee throughout the day": Caffeine consumption can exacerbate tinnitus symptoms in some individuals. Therefore, advising the client to limit caffeine intake, rather than specifying a quantity, would be more appropriate.

B. "You should practice deep breathing exercises": Deep breathing exercises and relaxation techniques can help reduce stress and anxiety, which may contribute to tinnitus symptoms. Stress management strategies can be beneficial in managing tinnitus-related distress.

C. "You can use at least 2,300 mg of sodium daily": High sodium intake may exacerbate tinnitus symptoms in some individuals. Advising the client to limit sodium intake would be more appropriate to potentially alleviate symptoms.

D. "You should avoid exercising": Regular exercise is generally beneficial for overall health and well-being, including stress reduction, which can help manage tinnitus symptoms. Therefore, advising the client to avoid exercising is not appropriate.

A. The client who is out of work and has been experiencing increased stress. B. The client who is recovering from a recent illness that caused vomiting and diarrhea. C. The client whose mother and uncle were diagnosed with this same condition. D. The client who had a myocardial infarction and required stent placement.

Correct Answer is D

Explanation

A. Stress can contribute to the development of atrial flutter, but it is not the highest risk factor compared to other options.

B. While electrolyte imbalances resulting from vomiting and diarrhea can predispose someone to arrhythmias, they are not as significant a risk factor for atrial flutter as other conditions.

C. A family history of atrial flutter may increase the likelihood of developing the condition, but it is not as significant a risk factor compared to other options.

D. A history of myocardial infarction and stent placement indicates underlying heart disease, which is a significant risk factor for developing atrial flutter. Cardiac events like myocardial infarction can lead to structural changes in the heart, such as scarring or remodeling, which can predispose individuals to atrial flutter. Therefore, this client is at the highest risk for developing atrial flutter among the options provided.
