place her in the recovery position and monitor for vomiting
Ischemic heart disease is MOST accurately defined as:
absent myocardial blood flow due to a blocked coronary artery
decreased blood flow to one or more portions of the myocardium
death of a portion of the heart muscle due to a decrease in oxygen
decreased blood flow to the heart muscle due to coronary dilation
An acute myocardial infarction (AMI) occurs when:
myocardial tissue dies secondary to an absence of oxygen
the heart muscle progressively weakens and dysfunctions
coronary artery dilation decreases blood flow to the heart
the entire left ventricle is damaged and cannot pump blood
Major risk factors for AMI include all of the following, EXCEPT:
hypoglycemia

angina usually occurs after an AMI
most patients with chest pain are experiencing an AMI
the cause of the pain cannot be diagnosed in the field
angina and AMI present identically

perform CPR for 1 to 2 minutes and then analyze her rhythm with an AED
alert the receiving hospital and perform CPR for the duration of the transport
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:

hypovolemia secondary to severe vomiting
widespread dilation of the systemic vasculature
Which of the following cardiac arrhythmias has the greatest chance of deteriorating into a pulseless rhythm?
sinus tachycardia
sinus bradycardia
extra ventricular beats
ventricular tachycardia
Ventricular tachycardia causes hypotension because:
the volume of blood returning to the atria increases
the right ventricle does not adequately pump blood
blood backs up into the lungs and causes congestion
the left ventricle does not adequately fill with blood
Sudden death following AMI is MOST often caused by:
cardiogenic shock
severe bradycardia

You are assessing the arm drift component of the Cincinnati Prehospital Stroke Scale on a 60-year-old woman. When she holds both of her arms out in front of her and closes her eyes, both of her arms immediately fall to her sides. You should:
repeat the arm drift test and ensure that her palms are facing downwards
repeat the arm drift test, but move the patient's arms into position yourself

Signs and symptoms of a hypertensive emergency would MOST likely be delayed in patients who:
have chronic hypertension
regularly take illegal drugs
have had a stroke in the past

When using the pulse oximeter as part of your assessment of a patient, it is important to remember that:
pulse oximetry is especially useful in patients who have cold extremities because vasoconstriction forces blood to the capillary beds
carbon monoxide has no effect on pulse oximetry readings because the pulse oximeter presumes that oxygen is saturating the hemoglobin
