How does the pro-dysrhythmic effect of antidysrhythmic drugs affect when they are used to treat dysrhythmias? They can also cause dysrhythmias or worsen existing ones. Only use it if benefits > risk What is a common mechanism by which drugs cause dysrhythmias? Interferes with ventricular pumping Describe how the following influences the use of antidysrhythmic drugs: Sustained vs. non-sustained dysrhythmias Non-sustained dysrhythmias: only use when they are symptomatic Sustained dysrhythmia...

Explain the significance of vasodilator selectivity in terms of the effects on Afterload. - correct answer Afterload: The force the heart has to work against to pump blood Drugs that affect arterioles lower cardiac afterload, resulting in increased cardiac output, tissue perfusion, and lower cardiac work Explain the significance of vasodilator selectivity in terms of the effects on Preload. - correct answer Preload: The degree of stretching the ventricular muscles does before contraction....

What are the 3 characteristics of a drug and which is most important? Effectiveness, safety (least amount of harm), and selectivity (acts specific to site and receptors) Effectiveness is the most important. Why is it important for antimicrobial testing prior to starting an antibiotic? To help figure out what the best antibiotic is to treat the infection, especially when having to treat antibiotic-resistant infections *Want to make sure the drug will kill the bug What is meant by onset of actio...

Reliability The instrument consistently measures a given trait with precision The accuracy with which an instrument measures the target attribute Item-total correlation Stability among individuals Inter-rater reliability Stability between raters Test-retest Stability over time reliability coefficient. Can range from .00 to 1.00. Coefficients below .70 are considered unsatisfactory. Coefficients of .80 or higher are desirable. Stability Internal consistency Equivalence What are the three asp...
