A patient has prescriptions for two inhalers. One inhaler is albuterol, and the other is fluticasone. Which instruction regarding these inhalers will the nurse give to the patient?

Choice A reason: Aspirin inhibits platelet aggregation by irreversibly blocking cyclooxygenase-1, reducing thromboxane A2 production, which increases bleeding risk. This is critical in patients with bleeding disorders, as it can exacerbate conditions like hemophilia or cause gastrointestinal bleeding, necessitating caution and monitoring during therapy.

Choice B reason: Taking aspirin on an empty stomach does not maximize effectiveness and may increase gastrointestinal irritation. Aspirin’s antiplatelet and analgesic effects are independent of food intake, but taking it with food reduces gastric mucosal damage, making this statement incorrect for patient safety.

Choice C reason: Aspirin is not safe with all medications, as it interacts with anticoagulants, NSAIDs, or corticosteroids, increasing bleeding risk. It also affects drugs like methotrexate by altering renal clearance. Drug interactions are common, requiring careful review of concurrent medications, making this statement misleading and unsafe.

Choice D reason: Moderate alcohol consumption with aspirin is not safe, as both irritate the gastric mucosa, increasing the risk of gastrointestinal bleeding. Aspirin’s antiplatelet effect combined with alcohol’s mucosal damage heightens this risk, making this statement incorrect and potentially harmful for patient education.

Choice A reason: Orange-tinged urine is an expected effect of rifampin, not a therapeutic response. It results from the drug’s red-orange metabolite excreted in urine, not an indicator of tuberculosis resolution. Clinical improvement, like reduced symptoms and negative cultures, better reflects the effectiveness of antitubercular therapy.

Choice B reason: A therapeutic response to antitubercular therapy is indicated by decreased symptoms (e.g., cough, fever), improved chest radiographs (reduced infiltrates), and negative sputum cultures, showing reduced Mycobacterium tuberculosis burden. These objective measures confirm the drugs, like isoniazid and rifampin, are effectively killing the bacteria and resolving the infection.

Choice C reason: Increased tolerance to antitubercular therapy or fewer adverse effects does not indicate a therapeutic response. Tolerance reflects patient adaptation to side effects, not bacterial clearance. Objective measures like symptom reduction and negative cultures are needed to confirm the therapy’s effectiveness against tuberculosis.

Choice D reason: Negative PPD results are not used to monitor active tuberculosis treatment. PPD tests detect latent tuberculosis or prior exposure, not active disease. Therapeutic response is assessed through symptom improvement, chest imaging, and sputum cultures, which directly indicate the reduction of active Mycobacterium tuberculosis infection.
