Answer to Question 1

B
Morphine and other opioid agonists do nothing to change the cause or transmission of pain. They bind to naturally occurring opioid receptor sites and alter a patient's perception of the painful experience.

Answer to Question 2

D
Skin lesions, itching, achy joints, and fever are signs of Stevens-Johnson syndrome, an adverse effect of class IV antidysrhythmic drugs (calcium channel blockers). These symptoms should be reported immediately to the prescriber and the drug should be held because this syndrome has the potential to be fatal.
