Rationale 2: Euphoria will not occur.
Rationale 3: Anger and rage would not be effects.
Rationale 4: A severe craving for more heroin is not likely to occur.

Answer to Question 2

Correct Answer: 2
Rationale 1: A reduction in symptoms might occur, but is not certain to occur, with the new medication.
Rationale 2: Partial blocking of dopamine results in fewer side effects than does complete blocking.
Rationale 3: If the client experiences fewer side effects from the drug, adherence might be improved, but that is not guaranteed.
Rationale 4: The client will not necessarily experience greater efficacy; each client responds differently to a drug.
Global Rationale: Partial blocking of dopamine results in fewer side effects than does complete blocking. A reduction in symptoms might occur, but is not certain to occur, with the new medication. If the client experiences fewer side effects from the drug, adherence might be improved, but that is not guaranteed. The client will not necessarily experience greater efficacy; each client responds differently to a drug.
