Answer to Question 1

C
Feedback:
If the heart muscle fails to do its job of pumping blood through the system effectively, blood backs up and the system becomes congested. This is called heart failure (HF). In the case described, the patient does not present with symptoms characteristic of a dysrhythmia, hypotension, or hypertension.

Answer to Question 2

A
Feedback:
Pyridostigmine is approved for management of myasthenia gravis, as an antidote to neuromuscular junction blockers, and to increase survival after exposure to nerve gas. Other options are not indications for use of this drug.
