EMT Chapter 16 Flashcards

The electrical impulse generated by the heart originates in the:

Which of the following signs is commonly observed in patients with right-sided heart failure?

Deoxygenated blood from the body returns to the:

A dissecting aortic aneurysm occurs when:

Signs and symptoms of a hypertensive emergency would MOST likely be delayed in patients who:

Angina pectoris occurs when:

A patient tells you that he has a left ventricular assist device (LVAD). Which of the following conditions should you suspect that he has experienced?

You and your partner arrive at the scene of a middle-aged man who collapsed about 5 minutes ago. He is unresponsive, apneic, and pulseless. Bystanders are present, but have not provided any care. You should:

A 66-year-old female with a history of hypertension and diabetes presents with substernal chest pressure of 2 hours' duration. Her blood pressure is 140/90 mm Hg, her pulse is 100 beats/min and irregular, her respirations are 22 breaths/min, and her oxygen saturation is 92%. The patient does not have prescribed nitroglycerin, but her husband does. You should:

When preparing to obtain a 12-lead ECG, the 'LL' and 'RL' electrodes should be placed:

Heart Function and Electrical Activity

The sinoatrial (SA) node generates electrical impulses that initiate heartbeats.
Deoxygenated blood from the body returns to the right atrium of the heart.

Heart Failure Indicators

Right-sided heart failure commonly causes dependent edema, which results in swelling in lower extremities.

Aortic Aneurysms

A dissecting aortic aneurysm occurs due to separation of the inner layers of the aorta, creating a false lumen.

Hypertensive Emergencies

Patients with chronic hypertension may have delayed signs and symptoms in a hypertensive emergency situation.

Angina Pectoris

Angina pectoris occurs when the myocardial oxygen demand surpasses its supply, indicating a need for better blood flow or oxygen delivery.

Left Ventricular Assist Device (LVAD)

Patients with an LVAD typically have a history of acute myocardial infarction (heart attack).

Cardiac Arrest Response

In cases of unresponsive, apneic, and pulseless patients, immediate high-quality CPR should be started, and AED pads should be applied as soon as possible.

Chest Pressure and Emergency Care

For a patient with substernal chest pressure lasting 2 hours, administer oxygen, give 324 mg of aspirin, and assess further, especially with a history of hypertension and diabetes.

12-Lead ECG Electrode Placement

The "LL" and "RL" electrodes for a 12-lead ECG should be placed on the thighs or ankles, ensuring proper monitoring of cardiac electrical activity.
