Answer to Question 1

D
Fentanyl is much more potent than morphine, as evidenced by its dosing in micrograms rather than milligrams.
Morphine does not elicit a greater response at a smaller dose than fentanyl.
Morphine and fentanyl do not have equal potency; fentanyl is much more potent.
Potency is defined as providing a stronger response at a smaller dosage.

Answer to Question 2

C
A deficiency of vitamin B12, not vitamin B6, would be expected; this statement indicates that further teaching is required.
With high-dose zidovudine, the patient can expect anemia, neutropenia, and folic acid deficien-cy.
