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 A

Explanation

A. Atrial fibrillation: Atrial fibrillation is characterized by an irregularly irregular rhythm, absence of identifiable P waves, and irregular ventricular response. The heart rate in atrial fibrillation can be variable, and the absence of identifiable P waves indicates disorganized atrial electrical activity.

B. Sinus bradycardia: Sinus bradycardia is characterized by a regular rhythm with a heart rate less than 60 beats per minute (bpm) and normal P waves preceding each QRS complex. In sinus bradycardia, the PR interval and QRS duration are typically within normal limits.

C. Supraventricular tachycardia: Supraventricular tachycardia (SVT) is characterized by a regular rhythm with a heart rate greater than 100 bpm. SVT typically presents with narrow QRS complexes and may or may not have discernible P waves.

D. First-degree heart block: First-degree heart block is characterized by a prolonged PR interval (>0.20 seconds) but maintains a regular rhythm with normal QRS duration. In first-degree heart block, P waves are typically identifiable, and the rhythm is not irregular.

A. "Note if you see any flashing bright lights on the grid." B. "Check to see if the lines on the grid are blurry or distorted." C. "Monitor for the lines on the grid to change in color or brightness." D. "Watch for floating dark spots on the grid."

Correct Answer is B

Explanation

A. "Note if you see any flashing bright lights on the grid." Flashing lights are not typically associated with macular degeneration. This symptom is more commonly associated with conditions like retinal detachment or migraine headaches.

B. "Check to see if the lines on the grid are blurry or distorted." This statement is correct. The Amsler grid is used to detect changes in central vision, which are common in macular degeneration. Patients with macular degeneration may perceive wavy or distorted lines instead of straight lines when looking at the grid, indicating central vision loss.

C. "Monitor for the lines on the grid to change in color or brightness." Changes in color or brightness of the lines on the grid are not typical features of macular degeneration. This statement does not accurately reflect the purpose of using an Amsler grid for macular degeneration.

D. "Watch for floating dark spots on the grid." Floating dark spots (floaters) are not typically associated with macular degeneration. Floaters are more commonly associated with conditions like posterior vitreous detachment or retinal detachment.
