Execute the plan

Looking at Table 1, patients taking Drug C had slightly elevated urine output, but normal urine potassium levels. So the correct answer will be a condition that can be treated solely by increasing urine output.

Answer by matching, eliminating, or guessing

Looking at the answer choices, the only one that can be treated solely by increasing urine output is edema, which is an accumulation of fluid in interstitial spaces. The correct answer is choice (C).

(A) might sound tempting; if Drug B doesn’t reduce blood pressure, maybe it can be used to raise blood pressure. However, the passage told us that the patients involved in the trial have blood pressures above 160/100, so Drug B still managed to reduce blood pressure, and this cannot be the answer. To treat dehydration, (B), we would want a drug that increases water retention in the body. Drug B resulted in high urine volume, so it would not increase water retention.

In hyperkalemia, (D) plasma potassium levels are elevated. Drug B did not elevate urine potassium levels, so it is unlikely that it would be effective in ridding the body of excess potassium.
