Chapter 16 ebook Quiz

Which of the following blood vessels transports oxygenated blood?

Pulmonary veins

Defibrillator pads are placed on the patient's chest:

with one pad to the right of the upper sternum and the other pad to the left lower chest below the armpit.

A patient with a left ventricular assist device (LVAD) tells you that the device's pump flow is continuous. Which of the following should you expect to encounter during your assessment?

Absence of a palpable pulse

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

An acute myocardial infarction (AMI) occurs when:

myocardial tissue dies secondary to an absence of oxygen.

Which of the following is a major difference between angina pectoris and AMI?

Anginal pain typically subsides with rest.

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

Aspirin

You and your partner have achieved return of spontaneous circulation (ROSC) in a patient who was in cardiac arrest. An ALS unit will arrive in less than 2 minutes. The patient remains unresponsive and has slow, irregular breathing. Further treatment for this patient should include:

BVM ventilation at 10-12 breaths/min and assessment of oxygen saturation.

Which of the following would cause the greatest increase in cardiac output?

Increased heart rate and increased stroke volume

A 66-year-old woman presents with a stabbing pain in the middle of her chest that radiates to her back. She tells you that the pain suddenly began about 30 minutes ago and has been severe since the onset. She has a history of hypertension, but admits to being noncompliant with her antihypertensive medications. When you assess her, you find that her blood pressure is significantly higher in her left arm than it is in her right arm. What do these signs and symptoms MOST likely indicate?

Dissecting aortic aneurysm

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

Common signs and symptoms of a hypertensive emergency include:

a bounding pulse, a severe headache, and dizziness.

Narrowing of the coronary arteries caused by a buildup of fatty deposits is called:

atherosclerosis.

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

automaticity

In contrast to an automatic implantable cardiac defibrillator (AICD), an external defibrillator vest:

delivers high-energy shocks, similar to an AED.

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

ensure that no one is touching the patient.

The main legal risk in using the AED is:

failing to deliver a shock when one is needed.

When obtaining a 12-lead ECG, the patient should be:

in a supine position with legs uncrossed.

The AED is MOST advantageous to the EMT because:

it delivers prompt defibrillation to patients with ventricular fibrillation.

Your EMS team is performing CPR on a 60-year-old male in cardiac arrest. You connect the AED, push the analyze button, and receive a "no shock advised" message. You should:

perform CPR for 2 minutes and reassess.
