JBL Registry Practice Test (250 Questions) With Verified Answers Graded A
You are giving a presentation to a group of laypeople on the importance of
... [Show More] calling EMS immediately for cardiac arrest patients. What point should you emphasize the MOST?
A: CPR and defibrillation are key factors in patient survival.
B: Laypeople are incapable of providing adequate CPR.
C: Rapid transport significantly reduces patient mortality.
D: Cardiac drug therapy is the most important EMS treatment. - A: CPR and defibrillation are key factors in patient survival.
Early high-quality CPR and defibrillation are the most crucial initial treatments to provide to a patient in cardiac arrest. Adequately performed CPR can keep the heart and brain oxygenated, thus increasing the chance of defibrillation success. Ventricular fibrillation (V-Fib) is the most common initial dysrhythmia seen in adult patients with sudden cardiac arrest and requires prompt defibrillation. Untreated V-Fib will rapidly deteriorate to asystole, the mortality rate from which is very high. You should also advise the audience that compression-only CPR has been linked to patient survival.
Prior to your arrival, a woman experiencing an asthma attack took two puffs from her prescribed inhaler without relief. After administering supplemental oxygen, you should:
A: perform a detailed secondary assessment.
B: contact medical control for further advice.
C: provide immediate transport to the hospital.
D: administer one more puff from her inhaler. - B: contact medical control for further advice.
Before assisting a patient with any medication other than oxygen, the EMT must ensure that the medication is prescribed to the patient and then obtain authorization from medical control. In this case, the physician probably will allow you to help the patient take one more puff from her inhaler. Generally, up to three puffs from an inhaler are delivered in the field. It is important for you to ask the patient how many puffs were taken from the inhaler before you arrived. The EMT must correct any airway and/or breathing problems as quickly as possible. After doing so, a secondary assessment can be performed.
In addition to supplemental oxygen, one of the MOST effective way to minimize the detrimental effects associated with acute coronary syndrome is to:
A: reassure the patient and provide prompt transport.
B: transport the patient rapidly, using lights and siren.
C: administer nitroglycerin in 15 to 20 minute intervals.
D: request ALS support for any patient who has chest pain. - A: reassure the patient and provide prompt transport.
Reason:
In addition to increasing the body's oxygen supply with supplemental oxygen, it is extremely important to decrease oxygen demand and consumption. You can most effectively accomplish this by keeping the patient calm, providing reassurance, and providing safe, prompt transport to the hospital. Traveling at a high rate of speed with lights flashing and siren blasting would clearly increase the patient's anxiety and the heart's demand for oxygen. The decision to request ALS support is based on the patient's condition and your transport distance to the closest appropriate hospital. Unless contraindicated (ie, the patient is hypotensive, the medication is not prescribed to the patient), nitroglycerin should be given in 5-minute intervals, up to three (3) doses.
