A nurse is caring for a client with asthma. Which of the following happens physiologically when bronchospasm occurs?
Decreased mucus production contributes to airway constriction.
Inflammation is reduced due to airway diameter.
Bronchospasm occurs when there is Inflammation, edema, and excess mucus.
Airway obstruction occurs due to thinning mucus.
The Correct Answer is C
Choice A Reason:
Decreased mucus production contributes to airway constriction: This statement is incorrect. Bronchospasm does not decrease mucus production; instead, it primarily affects the smooth muscles surrounding the bronchioles, leading to their constriction and narrowing of the airways. Increased mucus production, often accompanied by inflammation, can contribute to airway obstruction in conditions like asthma.
Choice B Reason:
Inflammation is reduced due to airway diameter: This statement is incorrect. Bronchospasm typically occurs in the setting of inflammation in conditions such as asthma. Constriction of the airways during bronchospasm exacerbates the inflammation and can further narrow the airways, leading to symptoms such as wheezing and dyspnea.
Choice C Reason:
Bronchospasm occurs when there is inflammation, edema, and excess mucus: This statement is partially correct. Bronchospasm often occurs in the presence of inflammation, edema, and excess mucus production, as seen in conditions like asthma. These factors contribute to airway hyperresponsiveness, leading to bronchospasm and airway narrowing.
Choice D Reason:
Airway obstruction occurs due to thinning mucus: This statement is incorrect. Airway obstruction in conditions like asthma is primarily due to bronchospasm, inflammation, and excessive mucus production, rather than thinning mucus. Thinning of mucus would not typically contribute to airway obstruction.

Correct Answer is D
Explanation
Choice A Reason:
Myelogram is not appropriate. This imaging test involves injecting contrast dye into the spinal canal to visualize the spinal cord and nerve roots. While it may help identify certain spinal cord abnormalities, it is not typically used as a primary diagnostic tool for multiple sclerosis.
Choice B Reason:
Brain natriuretic peptide (BNP) is not appropriate. This blood test measures the level of BNP, a hormone produced by the heart, which can be elevated in conditions such as heart failure. It is not used in the diagnosis of multiple sclerosis.
Choice C Reason:
Troponin level is not appropriate. Troponin is a protein released into the bloodstream during a heart attack or other heart-related conditions. This test is used to diagnose heart muscle damage and is not relevant to the diagnosis of multiple sclerosis.
Choice D Reason:
Lumbar puncture is appropriate. Also known as a spinal tap, a lumbar puncture involves collecting cerebrospinal fluid (CSF) from the spinal canal for analysis. In the diagnosis of multiple sclerosis, analysis of CSF can help identify certain abnormalities, such as an elevated level of immunoglobulin G (IgG) or the presence of oligoclonal bands, which are often indicative of inflammation in the central nervous system. Therefore, a lumbar puncture is commonly ordered to assist with the diagnosis of multiple sclerosis.
Correct Answer is D
Explanation
Choice A Reason:
Depression is incorrect. While depression can contribute to headaches in some individuals, it is more commonly associated with migraine headaches rather than tension-type headaches or cluster headaches. People with depression may experience changes in neurotransmitter levels and alterations in pain perception, which can exacerbate migraines. However, tension-type headaches and cluster headaches are generally less strongly associated with depression as a precipitating factor compared to migraines.
Choice B Reason:
Smoking is incorrect. Smoking can be a trigger for headaches in some individuals, particularly migraines, due to the vasoconstrictive effects of nicotine and other compounds in tobacco smoke. However, smoking is not universally recognized as a common precipitating factor for tension-type headaches or cluster headaches. While individuals with cluster headaches may have higher rates of smoking compared to the general population, it is not a factor commonly shared with tension-type headaches.
Choice C Reason:
Poor posture is incorrect. Poor posture can contribute to muscle tension and cervical spine strain, which may trigger tension-type headaches. However, poor posture is not typically considered a precipitating factor specific to cluster headaches. While tension-type headaches may be exacerbated by poor posture, cluster headaches are characterized by severe, unilateral pain typically centered around the eye or temple, with associated autonomic symptoms such as tearing, nasal congestion, or ptosis.
Choice D Reason:
Stress is correct. Stress is a well-established precipitating factor for both tension-type headaches and cluster headaches. Stress can lead to muscle tension and contraction, which are common triggers for tension-type headaches. Additionally, stress can also contribute to the onset or worsening of cluster headaches, although the exact mechanisms underlying this association are not fully understood. Therefore, stress is a common precipitating factor for both tension-type headaches and cluster headaches.
