What is the basis for the reduction in disturbed thought processes when a patient is administered haloperidol (Haldol)?

  • A. Reduction in the number of brain cells that crave dopamin
  • B. Dopamine receptors are enhanced, making more dopamine available.
  • C. Medication causes an increased cellular production of dopamine
  • D. Dopamine receptors are blocked, making dopamine less available.
Correct Answer: D

Rationale: The correct answer is D because haloperidol is a dopamine receptor antagonist. By blocking dopamine receptors, it reduces the activity of dopamine in the brain, which helps in reducing disturbed thought processes. Option A is incorrect as dopamine craving is not related to the mechanism of action of haloperidol. Option B is incorrect as enhancing dopamine receptors would increase dopamine activity, opposite to the intended effect of haloperidol. Option C is incorrect as increasing cellular production of dopamine would also increase dopamine activity, contradicting the purpose of using haloperidol.
