Question 3 of 5
Which nursing action should the nurse take first in order to assist a patient with newly diagnosed stage 1 hypertension in making needed dietary changes?

Question 4 of 5
The nurse is teaching a patient about some of the health consequences of uncontrolled hypertension. What is the most significant health consequence the nurse should emphasize?
Correct Answer: A
Rationale: Potential complications of hypertension include the following: left ventricular hypertrophy; MI; heart failure; transient ischemic attacks (TIAs); cerebrovascular accident; renal insufficiency and failure; and retinal hemorrhage. Venous insufficiency and right ventricular hypertrophy are not potential complications of uncontrolled hypertension. The original question was a multiple-answer type, but it has been restructured to a single-answer format emphasizing a key consequence (TIAs) while maintaining accuracy.
