Paramedic 2 Final Exam 2022/2023 with 100% correct answers

P wave The depolarization of the atria QRS Complex occurs after P wave, represents depolarization of the ventricles, usually last no longer than 0.12s T waves represented by repolarization of the atria and ventricles PR interval delay at the AV junction(.12-.20s) ST segment Period between ventricular depolarization and begining of repolarization. It should be the same level as the isoelectric line. R-R interval time between 2 ventricular depolarizations J-point begining of the T wave What might an elevated or depressed ST segment indicate? may indicate myocardial ischemia or injury. How does hyperkalemia look on a monitor? tall or sharp peaked T waves For a cardiac patient experiencing chest pain what is the proper dosage for morphine? 2-4-mg IV doses as needed for pain, being sure to reasses patients blood pressure, pulse, and respiratory rate after each dose until the patient experiences a relief in pain or or a drop in pulse or BP(less than 100) You respond to a call with an unconscious patient, what 2 pieces of equipment must always come with you off the truck?

How does right sided heart failure typically occur? as a result of left sided heart failure, also Pulmonary embolism, long standing COPD and Chronic bronchitis.

Hypotensive, right sided heart failure actually decreases the preload of the failing left side of the heart and may lesses pulmonary congestion. When would you not want to give a patient nitroglycerine? when they have a systolic blood pressure of 90! What does a patient having Acute Coronary syndrome typically complain of having? Chest pain described as heavy ,squeezing, crushing or tight. Pain radiates to the arms, WOMAN WILL COMPLAIN OF FATIGUE!!!!
