EMT Chapter 16 Quiz
Nitroglycerin is contraindicated in patients:
who have experienced a head injury.
Which of the following is NOT a common sign or symptom associated with malfunction of an implanted cardiac pacemaker?
A rapid heart rate
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
Which of the following signs is commonly observed in patients with right-sided heart failure?
Dependent edema
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.
Risk factors for AMI that cannot be controlled include:
family history.
Prior to attaching the AED to a cardiac arrest patient, the EMT should:
dry the chest if it is wet.
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.
A 49-year-old male presents with an acute onset of crushing chest pain and diaphoresis. You should:
obtain vital signs and a SAMPLE history.
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.
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.
