A patient taking levodopa/carbidopa for Parkinson disease experiences frequent "on-off" episodes (ie, the abrupt loss of effects) Which action by the nurse is best?
Administer the medication when the patient has an empty stomach.
Instruct the patient to avoid high-protein foods.
Have the patient increase the intake of vitamin B6.
Discontinue the drug for 10 days (for a "drug holiday").
The Correct Answer is B
Choice A rationale: Administering the medication with an empty stomach may enhance absorption but is not the best strategy for addressing "on-off" episodes.
Choice B rationale: The correct answer. High-protein foods can interfere with the absorption of levodopa, leading to "on-off" episodes.
Choice C rationale: Vitamin B6 supplementation is not typically used to address "on- off" episodes associated with levodopa/carbidopa.
Choice D rationale: Discontinuing the drug for 10 days (a "drug holiday") is not recommended and may result in a worsening of symptoms.

Correct Answer is A
Explanation
Choice A rationale: Prednisone can potentiate the effects of beta-blockers like metoprolol, and dose adjustments may be necessary to avoid excessive bradycardia.
Choice B rationale: Acetaminophen is not typically affected by prednisone in a way that requires dose adjustment.
Choice C rationale: Lisinopril is not typically affected by prednisone in a way that requires dose adjustment.
Choice D rationale: Insulin may need adjustment due to the hyperglycemic effects of prednisone.
Correct Answer is A
Explanation
Choice A rationale: Both methadone and buprenorphine can be prescribed for the treatment of opioid use disorder, and their availability is not limited to specialized addiction treatment centers.
Choice B rationale: While both medications can cause respiratory depression, it is not a defining characteristic of their use in opioid use disorder treatment.
Choice C rationale: Physical dependence is a potential concern with both medications, but the statement that physical dependence on buprenorphine is high is not accurate.
Choice D rationale: The statement that "Methadone is not addictive" is not accurate; both methadone and buprenorphine are used to manage opioid addiction.
