What is the process for electrical impulses of the heart? - ANSWER-- SA node (the heart's pacemaker) - Upper atrias contract - AV node sends impluses to ventricles - ventricles contract What are the different layers of blood vessels and what are the functions? - ANSWER-Tunica adventitia (outermost) - prevents collapse of blood vessel and provides protection Tunica media (middle) Tunica intima (innermost) Where is the temporal pulse? - ANSWER-In front of ear on the temple Where is ...

A palpable pulse is created by? - ANSWER-pressure waves through the arteries caused by cardiac contraction An elderly patient has fallen and hit her head. Your initial care should focus on? - ANSWER-airway, breathing, and circulation An injured patient is assigned a total score of 9 on the GCS. He is assigned a score of 2 for eye opening, a score of 3 for verbal response, and a score of 4 for motor response.

he EMT should assess a patient's tidal volume by? A. observing for adequate chest rise B. assessing the facial area for cyanosis C. counting the patient's respiratory rate D. measuring the patient's oxygen saturation - ANSWER-A. Observing for adequate chest rise Tidal volume- the volume of air that is moved in or out of lungs by single breath- observed by adequate chest rise. If rise is shallow, tidal volume is likely reduced. In an otherwise healthy individual, the primary stimulus t...

A 30-year-old male was rescued after being lost in the woods for approximately 18 hours. The outside temperature is 30°F (-1°C). He is immediately placed in the warmed ambulance, where you perform a primary assessment. He is unresponsive, pale, and apneic. You should: Select one: A. assess for a carotid pulse for up to 60 seconds. B. apply chemical heat packs to his groin and axillae. C. apply an AED and assess his cardiac rhythm. D. open his airway and give two rescue breaths. - ANSWER-A...

electrical conduction of the heart - correct answer The flow of electrical current causes smooth, coordinated heart contractions; they produce pumping action of the heart Depolarization - correct answer electrical charges on the surface of the muscle cell change from positive to negative Repolarization - correct answer the heart returns to its resting state, and the positive charge is restored to the surface Where do the electrical impulses begin? - correct answer Electrical impulses be...
