Answer to Question 1

Ans:
B

Feedback:

Atrial fibrillation is most often treated with anticoagulants to prevent embolic events as well as beta-blockers and digoxin. Cardioversion would not be a first-line intervention, and antihypertensives and diuretics would be unlikely treatments of choice.

Answer to Question 2

Ans:
A

Feedback:

Water is passively reabsorbed across tubular epithelial membranes, while ions like sodium, phosphate, and calcium necessitate active transport.
