Answer to Question 1

B
Atrial flutter or atrial fibrillation that has a ventricular rate of less than 100 beats/min is described as controlled. A controlled ventricular rate may be the result of a healthy AV node protecting the ventricles from very fast atrial impulses or medications used to control (block) conduction through the AV node, decreasing the number of impulses reaching the ventricles.

Answer to Question 2

B
To evaluate the rhythmicity of the ventricular rhythm on a rhythm strip, the interval between two consecutive R waves is measured. The distance between succeeding R-R intervals is measured and compared. If the ventricular rhythm is regular, the R-R intervals will measure the same.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
