NSG 531 Rush Advanced Pharmacology: Exam 3 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 ...

What is the ion that is important for the depolarization of the nodal cell? Ca++ What are the potential effects of CCBs? 1) Reduce cardiac Automaticity 2) Reduce AV nodal conduction 3) Cause vasodilation What are the three main chemical classes of CCBs? 1) Phenylalkylamines 2) Benzothiazepines 3) 1,4-Dihydropyridines What phase of the ventricular action potential is Ca++ most important for? Plateau/ phase II Plays a role in the contraction of ventricles What chemical class does *Verapamil* b...

All CCB are racemic mixtures except? Dilt and Nifedipine Non-Dihydropyridines Verapamil and diltiazem Dihydropyridines Nifedipine, Nicardipine, Nimodipine, Felodipine, Isradipine, Nisoldipine Amlodipine, Clevidipine Adverse affects of CCBs are similar except that dihydropyridines never cause what? Bradycardia (usually have reflex tachycardia) CCBs mechanism of action? Bind to unique sites on the a1 subunit of L-type voltage-gated channels Decreasing intracellular calcium Non-dihydropyridine...

exam 2 multiple answers A&P IICheck all that are characteristics of cardiac muscle. A. Cells are long and cylindrical. B. Cells are short and branching. C. Cells have multiple nuclei at the periphery of the cell. D. Cells have one or two nuclei in the center of the cell E. They are composed of thick and thin filaments. F. The functional contractile unit is the sarcomere. - correct answer B, D, E, F Check all that occur during ventricular systole A. The AV valves open to allow blood to...

CCBs mechanism inhibit Ca2+ influx through L-type (voltage gated) calcium channels (LTCC) CCBs actions act on Ca2+ entry into vascular smooth muscle (vasodilate), cardiac muscle (decrease force of contraction), SA nodal tissues (reduce contraction rate), AV node (decrease conduction velocity) Therapeutic Indications - Hypertension CCBs Dihydropyridines Therapeutic Indications - Arrhythmias CCBs Verapamil Therapeutic Indications - Angina CCBs Verapamil/Diltiazem Advantages with CCBs Do not i...
