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

Answer and Explanation

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 B

Explanation

A. Hyperactivity of sweat glands:

In cystic fibrosis (CF), there is an abnormality in the CF transmembrane conductance regulator (CFTR) protein, leading to increased salt concentration in sweat. However, this is not the primary factor responsible for the diverse clinical manifestations in CF. The primary issue lies in the abnormal production of thick and sticky mucus affecting various organs.

B. Mechanical obstruction caused by increased viscosity of mucous gland secretion:

This is the correct choice. CF is characterized by the production of thick and sticky mucus due to abnormal CFTR protein function. This increased viscosity leads to mechanical obstruction in organs such as the respiratory, digestive, and reproductive systems, causing a range of clinical manifestations.

C. Hypoactivity of the autonomic nervous system:

CF is not characterized by hypoactivity of the autonomic nervous system. The primary issue lies in the mechanical obstruction caused by the abnormal mucus production.

D. Atrophic changes in the mucosal wall of the intestines:

Atrophic changes in the mucosal wall of the intestines are not the primary factor responsible for the clinical manifestations of CF. The key problem is the mechanical obstruction due to increased viscosity of mucous gland secretions.

A. "You should always hold your child's hand when crossing the street." B. "Swim lessons would be important now to ensure your child is safe around a pool." C. "Medications with child proof tops are safe to keep on the counter so you remember to take them." D. "All small objects should be kept out of your child's view since he may aspirate them."

Correct Answer is C

Explanation

A. "You should always hold your child's hand when crossing the street."

This is a critical teaching point. Holding a child's hand while crossing the street is an important safety measure to prevent accidents and ensure the child's safety.

B. "Swim lessons would be important now to ensure your child is safe around a pool."

This is also a critical teaching point. Swim lessons can be essential for water safety, especially if there is a pool in the vicinity.

C. "Medications with childproof tops are safe to keep on the counter so you remember to take them."

This statement is incorrect. Medications, even with childproof tops, should be stored out of reach of children to prevent accidental ingestion. It's important to emphasize proper medication storage.

D. "All small objects should be kept out of your child's view since he may aspirate them."

This is a valid teaching point. Small objects can pose a choking hazard, and keeping them out of a child's reach is crucial for safety.
