A client's medication regimen is being determined by the health care provider. Currently, the medications haloperidol (Haldol), a high-potency drug, and chlorpromazine, a low-potency drug, are being considered
Which doses of the medications does the nurse anticipate for this client?
1. 2 mg of chlorpromazine and 2 mg of haloperidol (Haldol).
2. 100 mg of chlorpromazine and 2 mg of haloperidol (Haldol).
3. 100 mg of chlorpromazine and 100 mg of haloperidol (Haldol).
4. 2 mg of chlorpromazine and 100 mg of haloperidol (Haldol).
Correct Answer: 2
Rationale 1: 2 mg of chlorpromazine and 2 mg of Haldol would make both high-potency drugs.
Rationale 2: Low-potency drugs are those that require higher doses, and high-potency drugs are those that are able to control symptoms with low doses.
Rationale 3: 100 mg of chlorpromazine and 100 mg of Haldol would make both low-potency drugs.
Rationale 4: Chlorpromazine is a low-potency drug and requires a higher dose than the high-potency drug Haldol.
Global Rationale: Low-potency drugs are those that require higher doses, and high-potency drugs are those that are able to control symptoms with low doses. 2 mg of chlorpromazine and 2 mg of Haldol would make both high-potency drugs. 100 mg of chlorpromazine and 100 mg of Haldol would make both low-potency drugs. Chlorpromazine is a low-potency drug and requires a higher dose than the high-potency drug Haldol.
