A client with lupus asks about the differences between discoid and systemic lupus. Which statement by the nurse is correct?

A. Reinforce the importance of using the inhaler before exercise: While using a short-acting beta-agonist (SABA) before exercise can prevent exercise-induced bronchospasm, the patient’s frequent daily use indicates poorly controlled asthma, which requires more than preventive measures.

B. Instruct the patient to increase fluid intake: Hydration is generally beneficial but does not address the underlying issue of frequent SABA use or uncontrolled asthma. Increasing fluids alone will not improve asthma control.

C. Document the finding in the chart: Documentation is important, but it is not sufficient as a standalone action when a patient exhibits frequent rescue inhaler use. Immediate clinical intervention is warranted.

D. Notify the healthcare provider for possible adjustment of maintenance therapy: Using a SABA five times per day signals inadequate asthma control and potential need for stepping up controller therapy, such as inhaled corticosteroids. Notifying the provider ensures timely evaluation and adjustment to prevent exacerbations.

A. To prevent the breakdown of dopamine in the liver: Levodopa is converted to dopamine in the brain, not the liver. Carbidopa does inhibit peripheral decarboxylation of levodopa, but the primary goal is not general liver metabolism prevention, rather to increase CNS availability.

B. To reduce muscle rigidity by acting peripherally: Levodopa/carbidopa alleviates rigidity and bradykinesia by increasing central dopamine levels, not through peripheral action. Peripheral effects alone do not sufficiently improve Parkinson’s symptoms.

C. To cure Parkinson's disease: Levodopa/carbidopa is a symptomatic treatment that improves motor function. It does not halt disease progression or cure the neurodegenerative process.

D. To increase the amount of levodopa that reaches the brain: Carbidopa inhibits peripheral conversion of levodopa to dopamine, allowing more levodopa to cross the blood-brain barrier. This enhances efficacy while reducing peripheral side effects such as nausea and hypotension.
