Which of the following statements is true regarding the use of long-acting and short-acting inhalers for asthma management?

Short-acting inhalers should be used before exercise to prevent long-term asthma symptoms.

Long-acting inhalers can replace the need for short-acting inhalers entirely.

Short-acting inhalers should be taken daily to prevent asthma attacks.

Long-acting inhalers should be used regularly to maintain control of asthma symptoms.

Answer and Explanation

The Correct Answer is D

Rationale:
A. Short-acting inhalers (rescue inhalers, e.g., albuterol) can be used before exercise to prevent exercise-induced bronchospasm, but they are not meant for long-term control.
B. Long-acting inhalers (e.g., salmeterol, formoterol) do not replace short-acting inhalers; patients still need rescue inhalers for acute symptoms.
C. Short-acting inhalers are not taken daily; they are used only as needed for quick relief of acute symptoms.
D. Long-acting inhalers are taken regularly as maintenance therapy to provide ongoing control of asthma symptoms and prevent exacerbations.

Correct Answer is C

Explanation

Rationale:
A. Improvement with antihistamines is characteristic of allergic asthma, not nonallergic asthma.
B. Symptoms triggered by pollen exposure indicate allergic asthma.
C. Wheezing and shortness of breath during exercise is a hallmark of nonallergic (exercise-induced) asthma, which is triggered by physical activity rather than allergens.
D. Symptoms occurring only during spring and fall are linked to seasonal allergic asthma, not nonallergic asthma.

A. instruct the patient to avoid all physical activity to prevent shortness of breath. B. Recommend a high-carbohydrate diet to increase energy levels C. Encourage the patient to perform pursed-lip breathing exercises. D. Advise the patient to drink less water to prevent fluid overload.

Correct Answer is C

Explanation

Rationale:
A. Avoiding all physical activity is not recommended. Moderate activity, with rest periods, can improve endurance and lung function in COPD patients. Complete inactivity worsens deconditioning.
B. A high-carbohydrate diet is not appropriate because it increases CO₂ production during metabolism, which can worsen respiratory acidosis. A diet higher in fat and protein is generally preferred.
C. Pursed-lip breathing exercises are essential for COPD patients. They help prevent airway collapse, improve ventilation, promote CO₂ elimination, and reduce dyspnea.
D. Restricting fluids is not typically indicated for COPD patients unless another condition (e.g., heart failure) requires it. Adequate hydration is necessary to thin secretions and aid airway clearance.
