Answer to Question 1

d

Answer to Question 2

B
Beta blockers cause blockade of cardiac beta1 receptors, which can result in reduced atrioventri-cular conduction.
Two different medications are not generally needed to improve a hypertensive crisis.
The dilemma is the hypertensive crisis, which may lead to AV block, not the reflex tachycardia.
Cough is not a side effect of this beta blocker and does not contribute to a cardiac dysrhythmia; this would be the least concern of the scenario.

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.
