To achieve therapeutic effectiveness, a nurse teaches a patient with chronic asthma to use an inhaled glucocorticoid medication according to which schedule?
To abort an asthma attack
Only in an emergency
On a daily basis
2 weeks on, 2 weeks off
The Correct Answer is C
Choice A reason: Inhaled glucocorticoids, like budesonide, reduce airway inflammation over time but don’t act quickly enough to abort acute asthma attacks. Short-acting beta-agonists (e.g., albuterol) are used for acute relief, as glucocorticoids lack immediate bronchodilatory effects, making this choice incorrect for chronic asthma management.
Choice B reason: Using inhaled glucocorticoids only in emergencies is ineffective for chronic asthma. These drugs prevent inflammation and exacerbations through consistent use, not acute intervention. Emergency use is reserved for rescue inhalers like albuterol, making this choice inappropriate for long-term asthma control.
Choice C reason: Inhaled glucocorticoids require daily use to maintain anti-inflammatory effects, reducing airway hyperresponsiveness and preventing asthma exacerbations. Consistent dosing ensures steady suppression of chronic inflammation, improving lung function and reducing symptoms, making this the correct choice for managing chronic asthma effectively.
Choice D reason: A 2-week on/off schedule disrupts the consistent anti-inflammatory action of inhaled glucocorticoids needed for chronic asthma control. Intermittent use reduces efficacy, allowing inflammation to rebound, increasing exacerbation risk. Daily use is standard to maintain therapeutic benefits, making this choice incorrect.

Correct Answer is A
Explanation
Choice A reason: Mannitol, an osmotic diuretic, reduces intracranial pressure by drawing fluid from brain tissue into the bloodstream. This is its primary use in head injuries, making it correct.
Choice B reason: Mannitol is not primarily for peripheral edema; it targets cerebral edema. Furosemide is used for peripheral fluid, so this is incorrect for mannitol’s purpose.
Choice C reason: Mannitol removes fluid, not restores it. extracellular fluid, aiming to reduce brain swelling. Restoring fluid is opposite its effect, so this is incorrect.
Choice D reason: Mannitol increases renal perfusion by promoting diuresis, not reducing it. Its main goal is intracranial pressure reduction, so this is incorrect.
Correct Answer is D
Explanation
Choice A reason: Low drug interactions are desirable but unrelated to ease of administration. Adherence is directly tied to administration simplicity, so this is incorrect.
Choice B reason: Low production cost is a manufacturing benefit, not administration ease. Patient adherence is the outcome of easy administration, so this is incorrect.
Choice C reason: Storage stability aids logistics, not administration. Easy administration improves compliance, like taking oral pills, so this is incorrect for the outcome.
Choice D reason: Easy administration, like simple dosing or oral routes, enhances patient adherence by reducing barriers. This is the desired outcome, making it correct.
