The client has been on this dose of the medication for 3 years. Which of the following data is most likely significant in relation to the cause of the low blood pressure?
Correct Answer: B

D) Decreased pulse volume and increased pulse rate are signs of an acute hypotensive episode. Inadequate fluid volume when taking vasodilators can result in a drop in blood pressure when vasodilation starts to physiologically occur as an action of the drug. A potassium level of 3.3 would not be associated with a significant drop in blood pressure.
