Answer to Question 1

D
Feedback:
Ventricular fibrillation is seen as a bizarre, irregular, distorted wave. It is potentially fatal because it reflects a lack of any coordinated stimulation of the ventricles. The ventricles' inability to contract in a coordinated fashion results in no blood being pumped to the body or the brain. Thus, cardiac output is totally lost. Sinus bradycardia, sinus tachycardia, and atrial flutter may all require attention but are not as life threatening as ventricular fibrillation.

Answer to Question 2

B
Feedback:
The patient who is being treated for myasthenia gravis and his or her significant other should both receive instruction in drug administration, warning signs of drug overdose, and signs and symptoms to report immediately to enhance patient knowledge about drug therapy and to promote compliance. Missed doses should not be doubled with next dose because this will lead to overdosage. Patients with myasthenia gravis will experience muscle weakness and should not be pushed to do more than they can tolerate. Level of consciousness is not a concern in patients with myasthenia gravis.
