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

Answer and Explanation

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 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.

A. "Antibiotics are seldom prescribed." B. "Maybe you can borrow some money to get the medicine." C. "Your health care provider may be able to give you free samples." D. "Where did your money go this month?"

Correct Answer is C

Explanation

Choice A Reason:

"Antibiotics are seldom prescribed," is not an appropriate response as it does not address the client's concern about the cost of medication and may also be inaccurate depending on the specific diagnosis and treatment plan.

Choice B Reason:

"Maybe you can borrow some money to get the medicine," may not be feasible for the client and can also be perceived as insensitive or dismissive of their financial situation.

Choice C Reason:

"Your health care provider may be able to give you free samples. “offers a compassionate and practical solution to the client's concern about the cost of medication. Many healthcare providers have access to free medication samples provided by pharmaceutical companies, which they can offer to patients who have financial difficulties.

Choice D Reason:

"Where did your money go this month?" is judgmental and inappropriate. It may make the client feel ashamed or defensive about their financial situation, which is not conducive to a therapeutic nurse-client relationship. Additionally, the client's financial decisions are not relevant to their need for medical treatment.
