Chapter 16

Which of the following is NOT a common sign or symptom associated with malfunction of an implanted cardiac pacemaker?

a rapid heart rate

A 49-year-old male presents with an acute onset of crushing chest pain and diaphoresis. You should:

assess the adequacy of his respirations

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?

acute myocardial infarction

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:

administer oxygen, give her 324 mg of aspirin and assess her further

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:

begin high quality CPR and apply the AED as soon as possible

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

dependent edema

Prior to attaching the AED to a cardiac arrest patient, the EMT should:

dry the chest if it is wet

Risk factors for AMI that cannot be controlled include:

family history

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

have chronic hypertension

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

immediately resume CPR

Angina pectoris occurs when:

myocardial oxygen demand exceeds supply

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

on the thighs or ankles

The EMT should use an AED on a child between 1 month and 8 years of age if:

pediatric pads and an energy reducing device are available

The EMT should use an AED on a child between 1 month and 8 years of age if

pediatric pads and an energy-reducing device are available.

A patient in cardiac arrest is wearing an external defibrillator vest, which is interfering with effective chest compressions. The EMT should:

remove the battery from the monitor and then remove the vest

Most AEDs are set up to adjust the voltage based on the impedance, which is the:

resistance of the body to the flow of electricity

Deoxygenated blood from the body returns to the:

right atrium

The electrical impulse generated by the heart originates in the:

sinoatrial node

A dissecting aortic aneurysm occurs when:

the inner layers of the aorta become separated

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

Nitroglycerin is contraindicated in patients:

took 5 mins ago, took 3 doses, BP<100 sys, ALOC, sexual enhancing drugs, head injury
