It receives oxygenated blood from the lungs.

The MOST common error associated with the use of the AED is:

failure of the EMT to ensure the battery is charged.

Which of the following cardiac arrhythmias has the greatest chance of deteriorating into a pulseless rhythm?

ventricular tachycardia.

Angina pectoris occurs when:

myocardial oxygen demand exceeds the supply.

After the AED has delivered a shock, the EMT should:

immediately resume CPR.

family history.

When assessing for fluid collection in the lungs during auscultation of lung sounds, you should:

start at the lower lung fields and determine at which level you start hearing clear breath sounds.

inspiration and expiration.

Upon arriving at the residence of a patient with a possible cardiac problem, it is MOST important to:

assess the scene for potential hazards.

The electrical impulse generated by the heart originates in the:

sinoatrial (SA) node.

An alert patient presents with a regular pattern of inhalation and exhalation and breath sounds that are clear and equal on both sides of the chest.

These findings are consistent with: adequate air exchange.

Major risk factors for AMI include all of the following, EXCEPT:

hypoglycemia.

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

have chronic hypertension.

Which of the following statements regarding the pain associated with AMI is correct?

It can occur during exertion or when the patient is at rest.

Rapid, labored breathing in a patient with signs and symptoms of AMI should make you suspicious for:

congestive heart failure.

The electrical stimulus that originates in the heart's primary pacemaker is controlled by impulses from the brain that arrive by way of the:

autonomic nervous system.

The ability of cardiac muscle cells to contract spontaneously without a stimulus from a nerve source is called:

automaticity

A 67-year-old female presents with difficulty breathing and chest discomfort that awakened her from her sleep. She states that she has congestive heart failure, has had two previous heart attacks, and has prescribed nitroglycerin. She is conscious and alert with adequate breathing. Her blood pressure is 94/64 mm Hg and her heart rate is 120 beats/min. Treatment for this patient includes:

placing her in an upright position.

Which of the following statements regarding the pain associated with AMI is correct?

It can occur during exertion or when the patient is at rest.

The inferior vena cava returns deoxygenated blood to the right side of the heart from all of the following areas, EXCEPT the:

brain

You are dispatched to a residence for a 56-year-old male with an altered mental status. Upon arrival at the scene, the patient's wife tells you that he complained of chest pain the day before, but would not allow her to call EMS. The patient is semiconscious; has rapid, shallow respirations; and has a thready pulse. You should:

begin ventilatory assistance.

Nitroglycerin relieves cardiac-related chest pain by:

reducing the overall workload on the heart through vasodilation and reduced blood pressure.

Which of the following medications is commonly given to patients with chest pain to prevent blood clots from forming or getting bigger?

Aspirin.

Common side effects of nitroglycerin include all of the following, EXCEPT:

hypertension.

A 67-year-old female with severe chest pain becomes unresponsive, pulseless, and apneic during transport. You should:

immediately begin CPR and attach the AED as soon as possible.

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

peripheral edema.

Which of the following statements regarding pulse oximetry is correct?

Pulse oximetry measures the percentage of hemoglobin that is saturated with oxygen, but does not measure the actual hemoglobin content of the blood.

Which of the following statements regarding anaphylaxis is correct?

Anaphylaxis is characterized by airway swelling and hypotension.

A patient with atherosclerotic heart disease experiences chest pain during exertion because the:

lumen of the coronary artery is narrowed and cannot accommodate increased blood flow.

The left ventricle has the thickest walls because it:

pumps blood into the aorta and systemic circulation.

Common signs and symptoms of AMI include all of the following, EXCEPT:

pain exacerbated by breathing.

Which of the following is MOST characteristic of adequate breathing?

24 breaths/min with bilaterally equal breath sounds and pink skin.

You are assisting an asthma patient with his prescribed metered-dose inhaler. After the patient takes a deep breath and depresses the inhaler, you should:

instruct him to hold his breath for as long as he comfortably can.

Deoxygenated blood from the body returns to the:

right atrium

When an electrical impulse reaches the AV node, it is slowed for a brief period of time so that:

blood can pass from the atria to the ventricles.

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

have chronic hypertension

Common signs and symptoms of acute hyperventilation syndrome include:

tachypnea and tingling in the extremities.

The head and brain receive their supply of oxygenated blood from the:

carotid arteries.

Which of the following statements regarding nitroglycerin is correct?

A maximum of five nitroglycerin doses should be given to a patient.

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, and her respirations are 22 breaths/min with adequate depth. The patient does not have prescribed nitroglycerin, but her husband does. You should:

administer oxygen, give her 2 (81mg each tablet) chewable aspirin, and assess her further.

Prior to defibrillating a patient with an AED, it is MOST important that you:

ensure that no one is touching the patient.

Which of the following represents the MOST appropriate method of
assisting a patient with his or her prescribed nitroglycerin tablet or spray?

Administer the medication sublingually and allow it to dissolve or absorb.

Which of the following veins is located inferior to the trunk?

Saphenous.

Which of the following cardiac arrhythmias has the greatest chance of deteriorating into a pulseless rhythm?

Ventricular tachycardia

The AED is MOST advantageous to the EMT because:

it delivers prompt defibrillation to patients with ventricular fibrillation.

When the myocardium requires more oxygen:

the arteries supplying the heart dilate.

In contrast to AMI, a dissecting aortic aneurysm:

often presents with pain that is maximal from the onset.

When afterload increases:

it becomes harder for the ventricle to push blood through the blood vessels.

In what area of the lungs does respiration occur?

Alveoli

A pleural effusion is MOST accurately defined as:

fluid accumulation outside the lung.

When would it be MOST appropriate for a patient to take his or her prescribed nitroglycerin?

chest pain that does not immediately subside with rest.

Ischemic heart disease is MOST accurately defined as: decreased

blood flow to one or more portions of the myocardium.

Narrowing of the coronary arteries due to a buildup of fatty deposits is called:

atherosclerosis

A dissecting aortic aneurysm occurs when:

the inner layers of the aorta become separated.

After assisting your patient with his or her nitroglycerin, you should:

reassess the blood pressure within 5 minutes to detect hypotension.

You are dispatched to an apartment complex where a 21-year-old female has apparently overdosed on several narcotic medications. She is semiconscious and has slow, shallow respirations. You should:

insert a nasopharyngeal airway and begin assisted ventilation.

Sudden death following AMI is MOST often caused by:

ventricular fibrillation.

Which of the following signs or symptoms would you NOT expect to encounter in a patient with congestive heart failure?

hypotension and flat jugular veins.
