Asthma is caused due to

Correct Answer: D

Rationale: The correct answer is D: Spasm in bronchial muscles. Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to difficulty breathing. Bronchial muscles in the airways undergo spasms, causing constriction and making it hard to breathe. Infection of the trachea (A) or lungs (B) may lead to respiratory symptoms but is not the primary cause of asthma. Bleeding into the pleural cavity (C) is unrelated to the pathophysiology of asthma. Therefore, the correct answer is D as it directly correlates with the underlying mechanism of asthma.

Correct Answer: B

Rationale: The correct answer is B, a 36-year-old who fractured his left femur. This client is not at risk for airway loss related to aspirated secretions because a femur fracture does not directly impact the airway or swallowing function. Traumatic brain injury (choice A), radiation therapy (choice C), and quadriplegia (choice D) can all impair the client's ability to protect their airway and increase the risk of aspirating secretions. Therefore, these clients are at higher risk compared to the client with a femur fracture.

Correct Answer: C

Rationale: The correct answer is C. Normal breath sounds over the lung fields are vesicular, characterized as quiet and low-pitched. A is incorrect because bronchial breath sounds over the trachea are high-pitched and loud. B is incorrect as these intermediate sounds occur near large airways, not throughout the lung fields. D describes adventitious sounds like wheezing or crackles, which are abnormal.
