Asthma results in what change in the respiratory system?
Paralysis of the bronchial wall.
Increased lumen in the alveoli.
Dilation of the bronchial tress.
Increase in mucus production.
The Correct Answer is D
Asthma is a chronic respiratory condition that affects the airways, causing episodes of wheezing, breathlessness, chest tightness, and coughing. The underlying changes in the respiratory system due to asthma include inflammation, increased mucus production, and bronchoconstriction (narrowing of the airways). Here’s a detailed explanation of how asthma affects the respiratory system and leads to increased mucus production:
Detailed Explanation
Inflammation:
Asthma causes inflammation of the bronchial walls. The airways become swollen and sensitive, responding strongly to various triggers such as allergens, pollutants, cold air, or exercise.
- Bronchoconstriction:
The muscles around the bronchi (the large air passages leading from the trachea to the lungs) tighten, causing the airways to narrow. This constriction makes it difficult for air to flow in and out of the lungs.
Increased Mucus Production:
In response to the inflammation, the goblet cells and submucosal glands in the bronchial walls produce excess mucus. This mucus is thicker and stickier than normal, contributing to the obstruction of the airways. The buildup of mucus further narrows the airways and makes it harder to breathe.
Airway Remodeling:
Over time, chronic inflammation can lead to structural changes in the airways, known as airway remodeling. This includes thickening of the airway walls, increased smooth muscle mass, and more mucus-producing cells, which perpetuates the cycle of airway obstruction and difficulty breathing.

Correct Answer is ["B","C","D"]
Explanation
Choice A reason:
Canceling Netflix by Internet service is not relevant to Mr. Jones’ discharge planning. While managing finances and subscriptions may be part of overall life management, it does not address the immediate safety and mental health needs of Mr. Jones.
Choice B reason:
Releasing information signed for family to secure Mr. Jones’ loaded gun or having the police secure the gun if needed prior to discharge is crucial for ensuring his safety. Removing access to firearms reduces the risk of self-harm and is an important step in discharge planning for someone with suicidal ideation.
Choice C reason:
Obtaining a psychiatric provider follow-up appointment as soon as possible and evaluating for PHP (Partial Hospitalization Program) or residential treatment with the treatment team is essential. Continuity of care and appropriate follow-up are critical for managing Mr. Jones’ depression and preventing relapse.
Choice D reason:
Assisting in developing a safety plan prior to discharge that is written with phone numbers and interventions is vital. A safety plan provides Mr. Jones with clear steps to take if he feels at risk of harming himself, including contact information for crisis services and supportive individuals.
Correct Answer is ["A","B","D"]
Explanation
Choice A reason:
Improvement in activities of daily living (ADLs) and displaying hopefulness in interactions with others are positive nonverbal cues indicating that therapy and medication are effective. These improvements suggest that Edward is regaining interest in daily activities and looking forward to the future.
Choice B reason:
Being less tearful and able to discuss openly the loss of his grandfather with friends and in group settings are signs that Edward is processing his grief and benefiting from therapy. Open communication about his loss indicates emotional progress and acceptance.
Choice C reason:
Continuing to isolate is not a positive nonverbal cue. Isolation suggests that Edward is still struggling with his depressive symptoms and not fully engaging with his support system. This behavior indicates that further intervention may be needed.
Choice D reason:
Smiling appropriately and interacting with peers are positive nonverbal cues that therapy and medication are working. These behaviors show that Edward is beginning to re-engage socially and experience moments of joy and connection.
