Cardiovascular Emergencies Flashcards
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
A dissecting aortic aneurysm occurs when:
The inner layers of the aorta become seperated
A patient is 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
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 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.
After the AED has delievered a shock, the EMT should:
Immediately resume CPR
Angina pectoris occurs when:
Myocardial oxygen demand exceeds supply
Deoxygenated blood from the body returns to the:
Right atrium
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
Nitroglycerin is contraindicated in patients:
Who has experienced a head injury
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
The electrical impulse generated by the heart originates in the:
Sinoatrial node
