Which is the primary effect of central-acting sympatholytics in a client who exhibits hypertension and anxiety?

  • A. Vasoconstriction and reduction of blood pressure and heart rate
  • B. Central-acting sympatholytics induce sedation and fatigue
  • C. Affects kidneys and reduces activity of renin
  • D. Block receptors for norepinephrine in the brain
Correct Answer: D

Rationale: Central-acting sympatholytics block alpha-2 receptors for norepinephrine in the brain stem. Consequently, heart rate and blood pressure are reduced, which adds to the beneficial effects in anxious clients with hypertension. Vasoconstriction will result in higher blood pressure. Central-acting sympatholytics may induce sedation and reduce renin activity in the kidneys but this is not the primary effect.
