Name a therapeutic agent that is known to interfere with a digoxin assay? | Aldosterone Antagonists |
Name a Beta-blocker that exhibits class 3 pharmacological action? | Sotalol |
Which class of drugs are most likely to cause early after- depolarizations in ventricular myocytes? | Potassium channel blockers |
Name an antiarrhythmic that requires thyroid function testing before starting? | Amiodarone |
What is the name of the enzyme that converts T4 into T3 inside the target tissues? | Iodothyronine deiodinase |
What is a goitre? | Large thyroid gland that is not producing thyroid hormones |
What is Exophthalmos? | Widening of the eyes |
What is Exophthalmos caused by? | Thyroid- stimulating immunoglobulin |
Name a beta blocker that has class 3 antiarrhythmic properties. | Sotalol |
When can Bisoprolol be used for rhythm control? | In a re-entrant rhythm that involves the AV node. (such as Wolff-Parkinson-White syndrome) |
What are the 4 classes of drugs found in the Vaughan-Williams classification of Anti-arrhythmic drugs? | 1- Sodium channel blockers 2- Beta blockers 3- Potassium channel blockers 4- Calcium channel blockers |
What is the mechanism of action of Digoxin? | Digoxin is a cardiac glycoside that increases the force of myocardial contraction and reduces conductivity within the atrioventricular (AV) node |

What is the name of the study that showed apixaban was superior to warfarin in preventing stroke? | ARISTOTLE |
What is the best reason for why we conduct drug therapeutic monitoring? | To monitor a drug with a narrow therapeutic range |
What are the 4 most common biological sample processing strategies? | - PPT (protein precipitation) - LLE (liquid liquid extraction) - SPE (solid phase extraction) - DAS (dilute and shoot) |
What is the most commonly used immunoassay in DTM (drug therapeutic monitoring)? | Enzyme-linked immunosorbant assay (ELISA) |
What is the most common ECG characteristic of atrial fibrillation? | Absent P waves |
What is the normal resting heart rate for adults? | 60 to 100 beats per minute |
What is the mechanism of action of Beta Blockers in treating atrial fibrillation? | They reduce automaticity and conduction through the AV node |
What class of drug is Warfarin? | Vitamin K antagonist |
