Answer to Question 1

ANS: B

Feedback
A Incorrect: This is too small a dose.
B Correct: Convert 0.125 mg to 125 mcg, then divide by 500 mcg = 0.25 times 2 mL = 0.5 mL
C Incorrect: This is an excessive dose. Remember the prescribed dose is less than (1/4 of) the on-hand dose so the volume must be 1/4 of the on-hand volume.
D Incorrect: This is an excessive dose. Remember the prescribed dose is less than (1/4 of) the on-hand dose so the volume must be 1/4 of the on-hand volume.

Answer to Question 2

ANS: D

Feedback
A Incorrect: This is a true statement.
B Incorrect: This is a true statement.
