Now, let's delve into some specific nursing procedures for various diagnostic tests: Performing an Electrocardiogram (ECG/ECG) 1. Assist the client into a comfortable supine position. 2. Instruct the client to remain as still as possible during the procedure. 3. Expose the client's chest, lower legs, and lower arms. 4. Cleanse and dry the skin where the ECG leads will be placed. 5. Attach the chest (precordial) leads and limb leads as per standard placement.

6. Secure the electrodes to flat areas on each of the client's extremities. 7. Run the ECG strip. 8. Print the electrocardiogram data and file it in the client's medical record. 9. Notify the physician of any unexpected or abnormal findings.

Oxygen Saturation Measurement

Oxygen saturation, reflecting arterial blood oxygen levels, is typically monitored using a pulse oximeter. The procedure involves: 1. Placing a sensor on the client's finger or an alternative site like the forehead, nose, or ear. 2. Continuously monitoring oxygen saturation, often in conjunction with vital signs. 3. This noninvasive procedure can also be performed by certified nursing assistants trained to take and record vital signs. Fecal Occult Blood Testing (Guaiac Screening)

1. Collect two small portions of the client's stool and place them on a commercially prepared slide. 2. Apply a drop of reagent liquid on the slide.

3. Observe for a color change within 60 seconds, indicating a positive result for occult blood.
