A nurse is educating a client about a new prescription for mesalamine for Crohn's disease. Which of the following statements by the client indicates an understanding of the teaching?

A. heart failure: While severe fluid loss and electrolyte imbalances can increase cardiac workload, heart failure is not a common direct complication of ulcerative colitis exacerbations. The primary concerns are related to volume depletion, electrolyte disturbances, and systemic inflammation rather than chronic cardiac dysfunction in the acute phase.

B. hypokalemia: Persistent diarrhea associated with ulcerative colitis results in significant loss of potassium through the stool. Hypokalemia can lead to muscle weakness, cardiac dysrhythmias, and decreased gastrointestinal motility. Monitoring serum potassium and initiating replacement therapy as needed are critical during prolonged diarrheal episodes.

C. deep vein thrombosis: Inflammatory bowel disease increases the risk of hypercoagulability, which can contribute to deep vein thrombosis. However, this is less immediate than electrolyte disturbances during an acute flare. DVT assessment is important but is not the first priority when evaluating a client with ongoing diarrhea.

D. hypocalcemia: Although malabsorption can eventually lead to calcium deficits, acute ulcerative colitis exacerbations rarely cause immediate hypocalcemia. Calcium loss is not directly linked to short-term diarrhea, making hypocalcemia a less likely acute complication.

A. Take the medication an hour before eating meals: Levodopa-carbidopa absorption can be impaired by dietary protein because amino acids compete with the drug for transport across the intestinal wall and blood-brain barrier. Taking the medication 30–60 minutes before meals allows optimal absorption and more consistent therapeutic effects, improving control of Parkinson’s disease symptoms such as bradykinesia and rigidity.

B. Take the daily dose at bedtime to minimize sedative effects: Levodopa-carbidopa is not primarily sedating, and dosing at bedtime would not provide symptom control during waking hours when mobility is most needed. Administering the medication during the day, timed appropriately around meals, ensures peak effectiveness during active periods.

C. Take the medication with protein to aid in absorption: Protein actually interferes with levodopa absorption by competing for the same transport mechanisms. High-protein meals can reduce the drug’s effectiveness, leading to increased “off” periods of Parkinson’s symptoms. Patients are typically advised to separate protein intake from medication timing.

D. Crush this medication before taking it, so it is easier to swallow: Many formulations of levodopa-carbidopa are enteric-coated or extended-release to protect the drug from gastric degradation and control absorption. Crushing the tablets can alter the pharmacokinetics, reduce effectiveness, and increase gastrointestinal side effects.
