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.

Correct Answer is ["C","D","E"]
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.
Correct Answer is A
Explanation
Choice A Reason:
Falls is correct. Among individuals aged 65 years and older, falls are the most common cause of spinal cord injuries. As people age, they may experience changes in balance, mobility, and bone density, which can increase their risk of falling. Falls can occur both at home and in other environments, such as during outdoor activities or in healthcare settings. Spinal cord injuries resulting from falls in older adults can have significant consequences, including decreased mobility, chronic pain, and loss of independence.
Choice B Reason:
Gunshot wounds is incorrect. Gunshot wounds can cause spinal cord injuries, but they are not the most common cause for individuals aged 65 years and older. Gunshot wounds tend to be more common in younger age groups or in specific contexts such as violence-related incidents, which are less frequent in older adults.
Choice C Reason:
Sporting accidents is incorrect. Sporting accidents can also lead to spinal cord injuries, especially in younger and more active individuals participating in high-impact sports. However, among individuals aged 65 years and older, participation in sporting activities that could result in spinal cord injuries is generally less common compared to younger age groups.
Choice D Reason:
Motor vehicle accidents is incorrect.
Motor vehicle accidents can cause spinal cord injuries, but they are not as common in the elderly population as they are in younger age groups. Older adults may have reduced driving frequency or may be more cautious on the road, which decreases their risk of motor vehicle accidents compared to younger individuals.
