Answers with Explanation:

1. Answer: D.

Despite the number of patients who come in taking Digoxin, it is important to remember that this medication comes with a large range of side effects. Bradycardia (along with any of the other SLUDGE Toxidrome symptoms) is a common effect due to the Parasympathetic activity of Digoxin. (Note: This is also the reason it works as a second-line agent for rate control of Atrial Fibrillation.) Yellow, halo-like vision changes (think Van Gogh’s ‘Starry Night’) are a more rare, but classic finding.

2. Answer: E.

In an acute toxicity study any end point parameter such as death, brain damage, liver damage etc. can be used to obtain information regarding a particular toxicant.
