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.

Explanation
Choice A rationale: Before administering lithium, the nurse should assess serum creatinine levels. Lithium is excreted by the kidneys, and impaired renal function can lead to lithium toxicity.
Choice B rationale: Serum troponin I and T levels are markers of cardiac damage and are not directly related to lithium therapy.
Choice C rationale: Fasting blood glucose level is not specifically related to the assessment needed before administering lithium.
Choice D rationale: Serum lipid profile is not directly related to the assessment needed before administering lithium.
Correct Answer is B
Explanation
Choice A rationale: A sore throat in a patient taking immunosuppressive medications requires further assessment and intervention beyond home remedies.
Choice B rationale: Assessing for fever is crucial, as an infection in a patient on immunosuppressive therapy can be serious and requires prompt attention.
Choice C rationale: Stopping cyclosporine abruptly without guidance from the provider can lead to rejection; this decision should be made by the healthcare provider.
Choice D rationale: Reassurance alone may not be appropriate, given the potential seriousness of infection in an immunocompromised patient.
