A nurse is assessing a client who has tension pneumothorax. Which of the following findings should the nurse expect following tracheal deviation?

Respiratory alkalosis

Increased venous return

Decreased cardiac output

Dilated ventricles

Answer and Explanation

The Correct Answer is C

Choice A Reason:

Respiratory alkalosis is incorrect. Tension pneumothorax typically leads to respiratory distress and hypoxemia rather than respiratory alkalosis. The respiratory alkalosis may occur initially due to hyperventilation in response to hypoxemia but would not be directly related to tracheal deviation.

Choice B Reason:

Increased venous return is incorrect. Tension pneumothorax actually leads to decreased venous return due to compression of the great vessels in the thorax, particularly the superior vena cava and the inferior vena cava. This compression results from the increased pressure within the thorax, which impedes blood flow back to the heart.

Choice C Reason:

Decreased cardiac output is incorrect. Tension pneumothorax can indeed lead to decreased cardiac output due to compression of the heart and the great vessels by the accumulating air in the pleural space. This compression decreases venous return and impairs cardiac function.

Choice D Reason:

Dilated ventricles is incorrect. As mentioned earlier, tension pneumothorax can lead to compression of the heart, including the ventricles. This compression can cause dilatation of the ventricles, particularly the right ventricle, due to increased afterload and decreased venous return.

Correct Answer is D

Explanation

Choice A Reason:

Dulaglutide is inappropriate. Dulaglutide is a medication used to treat type 2 diabetes by improving blood sugar control. It is not indicated for the management of neurogenic bladder or urinary incontinence.

Choice B Reason:

Montelukast sodium is inappropriate. Montelukast sodium is a medication primarily used to treat asthma and allergic rhinitis by blocking leukotrienes, which are inflammatory substances that contribute to asthma and allergy symptoms. It is not indicated for the management of neurogenic bladder or urinary incontinence.

Choice C Reason:

Glatiramer acetate is inappropriate. Glatiramer acetate is a medication used to treat relapsing-remitting multiple sclerosis (MS) by modulating the immune system. It is not indicated for the management of neurogenic bladder or urinary incontinence.

Choice D Reason:

Oxybutynin is appropriate. Oxybutynin is a medication commonly prescribed for the management of neurogenic bladder and urinary incontinence. It belongs to a class of medications called anticholinergics, which work by relaxing the bladder muscles and reducing bladder spasms. Oxybutynin helps control urinary urgency, frequency, and incontinence associated with neurogenic bladder, including spasm-induced incontinence.

A. Myelogram B. Brain natriuretic peptide C. Troponin level D. Lumbar puncture

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.
