Answer to Question 1

A
Feedback:
African Americans with dark eyes usually require an increased dosage and may have a prolonged time to peak effect. The need for an increased dose appears to be related to the amount of pigment in the person's eyes because people with darker-pigmented eyes require a higher dose. German, Irish, and Scandinavian Americans generally have less pigmentation in their eyes and are therefore less likely to need a greater dose.

Answer to Question 2

C
Feedback:
Loop diuretics increase excretion of sodium, water, and potassium most significantly. Although other electrolytes may be excreted, loss of magnesium, calcium, and zinc are usually not significant.
