In the treatment of an acute asthma exacerbation, albuterol is administered first because it provides rapid relief of bronchospasm, which is the immediate cause of breathing difficulty. Here’s why this approach is prioritized: 1. Albuterol’s Rapid Action: Albuterol is a short-acting beta-2 agonist (SABA) that quickly relaxes the smooth muscles of the airways, leading to bronchodilation. This improves airflow and relieves symptoms such as wheezing, shortness of breath, and chest tightness within minutes. 2. Prednisone’s Delayed Onset: Prednisone, an oral corticosteroid, is effective in reducing airway inflammation, which is a key underlying cause of asthma exacerbations. However, it takes several hours (4-6 hours or more) to begin exerting its anti-inflammatory effects. It is not suitable for immediate symptom relief. 3. Immediate Airway Relief is Critical: In an acute asthma exacerbation, the primary goal is to quickly reopen the airways to ensure adequate oxygenation and prevent respiratory failure. Albuterol is the fastest and most effective first-line treatment for this. 4. Combination Therapy: While albuterol provides immediate relief, prednisone is often started soon after to address the inflammatory component of the exacerbation. This combination helps prevent further worsening of symptoms and supports long-term recovery. In summary, albuterol is given first for rapid bronchodilation, while prednisone is added to reduce inflammation over time. Both medications play complementary roles in managing an asthma exacerbation.

Nice question Option B. Initiate CPR is actually the correct action for a 10-month-old infant who has a foreign body airway obstruction and is not breathing. Here’s the reasoning: 1. Unresponsiveness and No Breathing: Since the infant is not breathing, they are considered unresponsive. In this situation, the American Heart Association (AHA) and pediatric life support guidelines recommend starting CPR if the infant is unresponsive and not breathing, as the airway is already compromised. 2. Infant Obstruction Protocol: For infants with an airway obstruction: If they are responsive but choking, the recommended action is to deliver five back blows followed by five chest thrusts. However, if the infant becomes unresponsive during a choking episode, the next step is to initiate CPR immediately. 3. CPR as a Method to Clear Obstruction: In this case, performing CPR (specifically chest compressions) can help to dislodge the obstruction by increasing intrathoracic pressure, potentially forcing the object out. Why the Other Options are Incorrect: A. Heimlich Maneuver: The Heimlich maneuver is only for choking adults and children over the age of one. It's not recommended for infants due to the risk of injury. C. Four Back Blows and D. Four Thrusts: These techniques are used if the infant is responsive and actively choking but not for an unresponsive infant. In summary, CPR is the correct response because the infant is unresponsive and not breathing.

Nice explanation mam thank you ​@@Nursenifty
