Describe treatment of dysrhythmias correct answer: To determine if treatment is necessary, assess the patient. Then ask the following questions: Is he or she experiencing signs and symptoms of decreased cardiac output? Is the dysrhythmia potentially life threatening? If the answer to either of these questions is yes, the patient will need to treatment for the dysrhythmia. ***WE WILL DISCUSS TREATMENTS OF DYSRHYTHMIAS BASED UPON CURRENT ACLS TREATMENT ALGORITHMS CLINICAL MANIFESTATIONS ...

Refractory period in the action potential of cardiac muscle cells. - ANS: -absolute refractory period of 250 ms -Prevents wave summation and tetanus which would stop the pumping action of the heart synovial fluid functions - ANS: -nourishes the articular cartilages -removes their wastes -makes movements at synovial joints almost friction-free pleural fluid function - ANS: -acts as a lubricant that enables the lungs to expand and contract with minimal friction pericardial fluid functi...

NSG 531 Advanced Pharmacology: Exam Questions With Correct Answers Latest Updated 2024/2025 Graded A+. what is the difference between cardiac myocyte action potential and that of the CNS or ANS? - ANSWER nerve cell action potential is very short cardiac action potential is much longer they are longer to have adequate filling time in order to get a good contraction for a reasonable bolus of blood the only way this can happen is if the action potential is longer this will also mean that the ...
