An adult client has been diagnosed with impacted cerumen. The provider has ordered carbamide peroxide (Debrox) ear drops to be administered. Which of the following is the best action for the nurse to do for this client?

A. Reduction in frequency of COPD exacerbations: The combination of a long-acting beta2-agonist and an inhaled corticosteroid helps relax airway smooth muscles and reduce airway inflammation. This dual action improves airflow, decreases symptoms such as dyspnea, and lowers the risk and frequency of COPD exacerbations, enhancing disease management.

B. Exacerbation of inflammation and bronchoconstriction: Inhaled corticosteroids and LABAs work to decrease inflammation and promote bronchodilation. They do not worsen airway inflammation or constriction; rather, they improve respiratory function and symptom control.

C. Cure of underlying COPD pathology: COPD is a chronic, progressive disease with irreversible structural changes in the lungs. Medications like LABA/ICS improve symptoms and reduce exacerbations but do not cure the underlying pathology.

D. Prevention of pneumonia: While inhaled corticosteroids may slightly increase the risk of pneumonia in some COPD patients, the combination therapy is not intended to prevent infections. Its primary goal is symptom control and reduction of exacerbations.

A. Prokinetic drugs, such as metoclopramide (Reglan).: Metoclopramide enhances gastric motility by increasing acetylcholine activity in the gastrointestinal tract, which accelerates gastric emptying and reduces nausea. It is the drug of choice for delayed gastric emptying (gastroparesis).

B. Serotonin blockers, such as ondansetron (Zofran).: Ondansetron works by blocking serotonin receptors in the chemoreceptor trigger zone to prevent nausea and vomiting. It does not stimulate gastric motility or correct delayed gastric emptying.

C. Anticholinergic drugs, such as scopolamine.: Anticholinergics inhibit parasympathetic stimulation, which decreases gastrointestinal motility and secretions. They would worsen delayed gastric emptying by further slowing peristalsis.

D. Neuroleptic drugs, such as chlorpromazine (Thorazine).: Chlorpromazine acts on dopamine receptors to reduce nausea and vomiting but has significant sedative and extrapyramidal effects. It does not promote gastric motility.
