6.3 : 放射学检查 I：X 射线和 CT 扫描

Chest X-rays capture images of the chest, heart, lungs, and blood vessels to screen and diagnose respiratory issues.

They detect abnormalities like fluid, tumors, and foreign bodies.

Conversely, computed tomography or CT scans diagnose lesions that are challenging to assess with X-rays by offering a detailed, cross-sectional view of the body.

They are done with or without contrast and help identify pulmonary nodules, small tumors, mediastinal abnormalities, and hilar adenopathy.

Nurse's responsibilities for these radiological procedures include the following.

Advise the patient to undress to the waist, wear a gown, and remove metal jewelry.

For a chest x-ray, inform the patient to take a deep breath and hold for complete visualization during the X-ray.

For a CT scan, instruct the patient to lie still on the table while the scanner revolves around.

If a contrast agent is used, assess the patient's renal function by evaluating BUN and serum creatinine levels. Have the patient fast for 4 hours before the scan.

Check for shellfish allergies, as the contrast is iodine-based.
