A 5 year old child with asthma is ordered Albuterol. The nurse knows that the primary action of Albuterol is to:
decrease inflammation in the bronchioles to open up the airway
relax bronchial smooth muscles to decrease bronchospasm
slow the respiratory rate to improve oxygenation
decrease mucus production in the bronchioles to improve aeration
The Correct Answer is B
A. Decrease inflammation in the bronchioles to open up the airway:
This is more characteristic of corticosteroids, which are anti-inflammatory medications. Albuterol primarily acts as a bronchodilator, not an anti-inflammatory.
B. Relax bronchial smooth muscles to decrease bronchospasm:
This is the correct answer. Albuterol is a beta-2 adrenergic agonist that acts on bronchial smooth muscles, causing them to relax and reducing bronchospasm.
C. Slow the respiratory rate to improve oxygenation:
Albuterol is not typically associated with slowing the respiratory rate. Instead, it works by dilating the airways.
D. Decrease mucus production in the bronchioles to improve aeration:
Albuterol primarily addresses bronchospasm, and while it may indirectly help with mucus clearance, reducing mucus production is not its primary action.

Correct Answer is D
Explanation
A. Document B/P not obtained because the child was in the playroom.
This is not the best option. The nurse should attempt to obtain the blood pressure as part of routine monitoring.
B. Take the child back to their room, take their B/P and then take them back to the playroom.
This may disrupt the child's play and is not the most efficient approach for routine blood pressure monitoring.
C. Take the child to the treatment room.
This might be unnecessary for a routine blood pressure check and could cause unnecessary anxiety for the child.
D. Take the B/P in the playroom.
This is the best intervention. If possible, taking the blood pressure in the playroom allows the child to remain in a familiar and comfortable environment, reducing anxiety and promoting cooperation.
Correct Answer is D
Explanation
A. Informing the child's parents about a tonsillectomy:
Tonsillectomy is not the immediate intervention for the symptoms described. This intervention is not necessary at this point.
B. Immediate IV placement:
While hydration may be necessary, immediate IV placement is not the primary intervention for a child with croup presenting with stridor and hoarseness.
C. A tracheostomy set at the bedside:
While croup can cause airway obstruction, preparing for a tracheostomy is not the initial intervention. Less invasive measures are typically attempted first.
D. Cool mist and respiratory treatment of racemic epinephrine:
This is the correct intervention. Croup, often caused by viral infections, can result in swelling of the upper airway, leading to the characteristic barky cough, stridor, and hoarseness. Administration of cool mist and racemic epinephrine can help reduce airway swelling and alleviate symptoms.
