Pacemaker Quiz: Can You Teach Safe Living?

1. A patient with a new pacemaker asks about using a microwave. What is the safest response?

Avoid microwave use entirely for 6 months

Microwaves are generally safe; maintain distance of at least 6 inches

Use only microwave ovens labeled pacemaker-safe

Microwave use is prohibited permanently

2. A patient with a pacemaker experiences syncope. What is the most likely cause?

Normal device function

Pacemaker malfunction or undersensing

Anxiety

Dehydration only

3. Which medication should be avoided or used cautiously in patients with pacemakers due to electromagnetic interference risk?

Aspirin

High-dose diathermy or transcutaneous electrical nerve stimulation

Metformin

Vitamin supplements

4. What does 'sensing' mean in pacemaker terminology?

The device's ability to detect the patient's intrinsic electrical activity

The device's ability to feel temperature changes

The device's ability to communicate with external programmers

The device's ability to measure blood pressure

5. A patient reports chest pain and shortness of breath 2 weeks after ICD implant. What should you assess first?

Anxiety level

Signs of infection or lead displacement at the incision site

Recent medication changes

Diet compliance

6. What is the most common reason for pacemaker replacement?

Lead fracture

Battery depletion

Device infection

Patient request

7. A patient with an ICD is scheduled for surgery. What preoperative intervention is necessary?

Program the device to asynchronous mode and disable shock therapy

Remove the device temporarily

No special precautions needed

Double the medication dosage

8. Which electromagnetic device poses the greatest risk to pacemaker function?

Television remote control

Industrial welding equipment or high-powered magnets

Refrigerator

Digital thermometer

9. A patient asks if they can undergo an MRI with their pacemaker. What is your best response?

MRI is absolutely contraindicated

Newer MRI-compatible devices may allow it with programming precautions

MRI is safe only if the device is more than 5 years old

MRI can be done without any device adjustments

10. How should you position a patient during a pacemaker or ICD check-up using a programmer?

Sitting upright with arms crossed

Lying supine with the wand placed over the device

Standing with the device exposed

Any position is acceptable

11. An ICD has detected ventricular fibrillation. What is the device's primary action?

Alert the patient to call 911

Deliver a defibrillating shock to restore normal rhythm

Release medication into the bloodstream

Increase pacing rate gradually

12. What should patients avoid when using cell phones with a pacemaker or ICD?

Holding the phone directly over the device on the same side

Making calls during daylight hours

Using cell phones at all

Text messaging specifically

13. Which device setting describes a pacemaker that fires only when the patient's intrinsic rate falls below the set rate?

Fixed rate

Demand mode

Synchronous mode

Asynchronous mode

14. What is the typical battery life of a modern pacemaker?

2 to 3 years

5 to 15 years

20 to 25 years

Permanent; never requires replacement

15. Which activity restriction is most important to teach a patient with a new ICD implant?

Avoid all contact sports and heavy lifting for 6 weeks

Never drive a car again

Limit walking to indoor areas only

Avoid swimming permanently

16. What is the primary function of a permanent pacemaker?

Deliver electrical impulses to regulate heart rhythm

Increase cardiac output by strengthening contractions

Prevent blood clots in the atria

Reduce cholesterol levels in coronary arteries

17. What is the recommended follow-up interval for a patient with a new pacemaker?

Every 6 months for the first year, then annually

Only if symptoms develop

Every 2 weeks indefinitely

Only at battery replacement time

18. A patient reports dizziness and hiccuping after pacemaker insertion. What complication should you suspect?

Normal healing response

Pacemaker-mediated tachycardia

Pacemaker malfunction or lead displacement

Infection at the insertion site

19. True or False: A patient with a pacemaker can safely use a heating pad directly over the device.

True

False

20. True or False: Patients with ICDs can participate in recreational sports such as golf and bowling.
