A child is admitted to the hospital with asthma. Which assessment findings support this diagnosis?

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.

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.
