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 A
Explanation
A. Use self/parent report, behavioral, and physiological factors
This choice emphasizes a comprehensive approach to pain assessment, considering self-report if the child can communicate, parent report for younger children or those unable to express themselves verbally, and a combination of behavioral and physiological factors. This approach recognizes the multidimensional nature of pain and aims to gather information from various sources for a more accurate assessment.
B. Ask the parents for a pain rating
While parents' input is valuable, relying solely on parental perception may not capture the full picture of the child's pain experience. It's important to consider other aspects, including the child's self-report (if possible) and behavioral and physiological factors.
C. Look for behavioral clues for pain such as crying
Behavioral observation is a crucial component of pain assessment. However, relying solely on crying may overlook subtle cues or variations in how different children express pain. A more comprehensive approach involves considering various behavioral indicators.
D. Use measures of heart rate and respiratory rate
Physiological measures, such as heart rate and respiratory rate, can provide additional information but should not be used in isolation. Physiological responses can vary, and other dimensions of pain assessment, including self-report and behavioral observations, should be considered for a more complete understanding.
Correct Answer is D
Explanation
A. "They will come around dinner time."
This response uses the term "dinner time," which might be too abstract for a young child. It doesn't provide a specific visual reference.
B. "It won't be much longer."
This response is somewhat vague and may not offer a clear understanding of when the parents will arrive. Young children may not grasp the concept of "much longer."
C. "They will be here soon."
Similar to choice B, this response is somewhat vague and relies on the child's interpretation of "soon," which can vary.
D. "Let me show you where 6 o'clock is on the clock."
This response is the most concrete and provides a visual reference by using the clock. It helps the child understand the passage of time in a more tangible way.
