How to find phenotypic ratio?
1.A cardiology nurse administered amiodarone (class III antiarrhythmic agent) to a patient suffering from tachyarrhythmia. What is the mechanism of action of this agent?
2.The heart rate of the patient in question 1 above is high after amiodarone was administered. The nurse now has in mind an agent that can also be antimalarial and anti-pyretic. Which agent does she have in mind?
3.A cardiologist observed damaged cardiac tissue in his patient who is experiencing tachycardia. He instructed the cardiology nurse on duty to administer an antiarrhythmic medication from a class of drugs that acts exclusively on both activated and inactivated sodium channels.
a) What antiarrhythmic drug is the cardiologist referring to?
b) What adverse effects should be monitored in the patient following
administration of this drug?
Jeff has learned from his urologist that his kidney disease has progressed to renal failure and that he must include dialysis in his treatment plan. Because you work on the dialysis unit of the hospital, Jeff has asked you to explain how the hemodialysis machine works. He also asks if the unit is portable so that he can use it at home, if necessary. What will you tell Jeff?
