A nurse is caring for a client who has a pulmonary embolism. The nurse should identify that the release of inflammatory mediators leads to which of the following pathologic findings?
Decreased pulmonary vascular resistance
Hypercapnia
Hypoventilation
Respiratory alkalosis
The Correct Answer is D
Correct answer: D
Choice A Reason:
Decreased pulmonary vascular resistance is incorrect. Inflammatory mediators released in response to a pulmonary embolism can lead to vasoconstriction and increased pulmonary vascular resistance. This is part of the body's response to redirect blood flow away from the affected area of the lung and maintain adequate perfusion to other areas.
Choice B Reason:
Hypercapnia is incorrect. Hypercapnia refers to elevated levels of carbon dioxide (CO2) in the blood. Hypocapnia usually is present with embolism; hypercapnia, on the other hand, is rare.
Choice C Reason:
Hypoventilation is incorrect. Hypoventilation occurs when there is inadequate ventilation of the lungs relative to metabolic demands. In the context of a pulmonary embolism, hypoventilation can occur due to factors such as pain, respiratory muscle fatigue, or impaired gas exchange, all of which can be influenced by the release of inflammatory mediators.
Choice D Reason:
Respiratory alkalosis is correct. In response to the blockage and the resulting inflammation, the body often increases the respiratory rate as a compensatory mechanism to maintain adequate oxygen levels and remove carbon dioxide. Due to the increased breathing rate, there is excessive exhalation of carbon dioxide, leading to a decrease in the partial pressure of CO2 in the blood. This results in an increase in blood pH, causing respiratory alkalosis.

Explanation
Choice A Reason:
Bladder spasms are not commonly reported as adverse effects of methylprednisolone. However, bladder dysfunction can occur in individuals with multiple sclerosis due to the disease process itself, but it is not specifically related to corticosteroid therapy.
Choice B Reason:
Hypotension is not a common adverse effect of methylprednisolone. In fact, corticosteroids can often lead to fluid retention and sodium retention, which can contribute to hypertension rather than hypotension.
Choice C Reason:
Delayed wound healing is correct. Corticosteroids can impair the body's ability to heal wounds by suppressing the inflammatory response and collagen synthesis. Therefore, clients receiving methylprednisolone may experience delayed wound healing, which can be problematic, especially in individuals with pre-existing wounds or undergoing surgical procedures.
Choice D Reason:
Hirsutism (excessive hair growth, especially in women) can occur with long-term corticosteroid use due to the effect of steroids on hair follicles. It is a possible adverse effect of methylprednisolone.
Choice E Reason:
Hyperglycemia is correct. Corticosteroids can increase blood glucose levels by promoting gluconeogenesis, reducing glucose uptake by tissues, and inducing insulin resistance. Clients receiving methylprednisolone may develop hyperglycemia, which can be particularly concerning for individuals with diabetes or those at risk of developing diabetes.

Explanation
Choice A Reason:
African American clients is appropriate. Research suggests that African Americans have a lower prevalence of MS compared to White Americans, but they tend to have more severe disease progression and higher disability rates when diagnosed with MS.
Choice B Reason:
White American clients: Individuals of European descent, including White Americans, have the highest prevalence of MS, particularly those of northern European ancestry. MS is more common in populations of northern European descent compared to other racial and ethnic groups.
Choice C Reason:
East Asian clients: East Asians, including individuals of Chinese, Japanese, and Korean descent, have historically had lower rates of MS compared to individuals of European descent. However, MS prevalence appears to be increasing in East Asian populations, possibly due to changes in lifestyle and environmental factors.
Choice D Reason:
Hispanic or Latino clients: Studies suggest that the prevalence of MS is lower in Hispanic/Latino populations compared to White Americans but higher than in African Americans. However, there is considerable variation in MS prevalence among different Hispanic/Latino subgroups.
Choice E Reason:
Navajo Indian clients: Native American populations, including Navajo Indians, have been reported to have a lower prevalence of MS compared to individuals of European descent. However, limited data are available on MS prevalence and incidence in specific Native American tribes, and more research is needed to fully understand the disease burden in these populations.
