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 ["46"]
Explanation
To provide adequate hydration for a toddler with dehydration, the nurse needs to calculate the daily fluid requirements based on the child's weight and then divide it by 24 hours to get the hourly rate.
For a 12 kg toddler, the daily fluid requirement is 1000 ml for the first 10 kg plus 50 ml for each additional kg, which equals 1100 ml.
Therefore, the hourly rate is 1100 ml / 24 hours, which is about 46 ml.
The nurse would set the pump at 46 ml per hour.
Correct Answer is D
Explanation
A. "I should keep my infected child away from his brother until he has recovered."
This statement is correct. Keeping an infected child away from siblings can help prevent the spread of bronchiolitis.
B. "I should insist that anyone who comes in contact with my children thoroughly wash their hands before playing with them."
This statement is correct. Handwashing is an important preventive measure to reduce the transmission of viruses that can cause bronchiolitis.
C. "I should insist that anyone with a respiratory illness avoid contact with my children until well."
This statement is correct. Avoiding contact with individuals who have respiratory illnesses helps reduce the risk of bronchiolitis.
D. "I should make sure both my children get a vaccination for bronchiolitis this year."
This statement needs further clarification. There isn't a specific vaccine for bronchiolitis. However, vaccination against certain viruses, such as the influenza virus (flu), can help prevent respiratory infections that may lead to bronchiolitis.
