| Question | Answer |
|---|---|
| A 12 lead electrocardiogram (ECG) is a; | A record of the electrical impulses of the heart |
| The electrocardiograph sensors are AKA; | Leads |
| The lead wires of an electrocardiograph are connected to; | Electrodes |
| The electrodes of an EKG are attached to; | The patients skin |
| EKG electrodes are coated with; | Conductor gel |
| Four EKG electrodes are attached to the ?__? and are called; | Limbs; Limb leads |
| 12 lead EKG procedure steps 1-4 | 1.Wash hands 2.Assemble equipment 3.Introduce yourself 4.Explain the procedure |
| 12 lead EKG procedure - Ask the patient to remove clothing (waist up) and put on; | A gown w/opening @ front |
| 12 lead EKG procedure - Ask the patient to remove; | All jewelry |
| 12 lead EKG procedure - Ask the patient to turn off; | Their electrical devices |
| 12 lead EKG procedure - The patient should be placed in what position? | Supine |
| 12 lead EKG procedure - Do not allow the arms or legs to; | Dangle |
| 12 lead EKG procedure - Cover the patient with a; | Sheet or blanket |
| 12 lead EKG procedure - Clean and ?__? the EKG electrode site with? | Abrade; with alcohol pads |
| Four EKG electrodes are attached to the ?__? and are called; | Legs; limb leads |
| Abrade means to; | Roughen by rubbing |
| 12 lead EKG procedure - If the patient has a hairey chest or legs it may be necessary to; | Trim the EKG electrode site |
