A patient is taking a drug that has known toxic side effects. What will the nurse do?
Discontinue the drug at the first signs of toxicity.
Teach the patient how to treat the symptoms if they develop.
Ensure that complete blood counts are ordered periodically.
Monitor the function of all organs potentially affected by the drug.
The Correct Answer is D
Choice A Reason:
Discontinuing the drug at the first signs of toxicity might seem like a straightforward solution, but it is not always the best approach. Some drugs are essential for treating serious conditions, and stopping them abruptly can cause more harm than good. Instead, the nurse should monitor the patient closely and consult with the healthcare provider to adjust the dosage or switch to a safer alternative if necessary.
Choice B Reason:
Teaching the patient how to treat symptoms if they develop is important, but it is not sufficient on its own. While patient education is a crucial aspect of managing drug side effects, it should be part of a broader strategy that includes regular monitoring and medical supervision.
Choice C Reason:
Ensuring that complete blood counts are ordered periodically is a good practice, especially for drugs that can affect blood cells. However, this approach is too narrow. Toxic side effects can impact various organs and systems, so a comprehensive monitoring plan is necessary.
Choice D Reason:
This is the correct answer. Monitoring the function of all organs potentially affected by the drug is the most comprehensive and effective approach. This includes regular blood tests, liver function tests, kidney function tests, and other relevant assessments. By closely monitoring the patient’s organ functions, the healthcare team can detect early signs of toxicity and take appropriate action to prevent serious complications.

Correct Answer is B
Explanation
Choice A Reason:
Increased neuromuscular excitability is not typically associated with respiratory acidosis. Instead, respiratory acidosis can lead to symptoms such as confusion, fatigue, and shortness of breath due to the buildup of carbon dioxide in the blood. Neuromuscular excitability is more commonly associated with conditions like hypocalcemia.
Choice B Reason:
This is the correct answer. Respiratory acidosis occurs when the lungs cannot remove enough carbon dioxide (CO2) from the body, leading to an accumulation of CO2 in the blood. This increase in CO2 results in the formation of carbonic acid, which lowers the pH of the blood. The elevated levels of carbonic acid are a hallmark of respiratory acidosis.
Choice C Reason:
Increased pH is not associated with respiratory acidosis. In fact, respiratory acidosis is characterized by a decrease in blood pH due to the accumulation of carbon dioxide and the subsequent increase in carbonic acid. Therefore, this choice is incorrect.
Choice D Reason:
Hypokalemia, or low potassium levels, is not typically associated with respiratory acidosis. Instead, respiratory acidosis can sometimes lead to hyperkalemia (high potassium levels) due to the shift of potassium out of cells in response to the acidotic state. Therefore, this choice is incorrect.
Correct Answer is ["A","B","C","E"]
Explanation
Choice A Reason:
Chronic stress can significantly impact mental health, leading to conditions such as depression. The persistent activation of the stress response system, particularly the release of cortisol, can alter brain function and structure, contributing to mood disorders. Studies have shown that prolonged exposure to stress hormones can lead to changes in the brain that are associated with depression.
Choice B Reason:
Impaired cognitive function is another consequence of chronic stress. Elevated levels of cortisol over an extended period can damage the hippocampus, a region of the brain involved in memory and learning. This can result in difficulties with concentration, memory, and decision-making. Chronic stress has been linked to cognitive decline and an increased risk of neurodegenerative diseases.
Choice C Reason:
Chronic stress can also affect the immune system, leading to autoimmune diseases. The continuous activation of the stress response can cause immune dysregulation, where the body’s immune system mistakenly attacks its own tissues. This can result in conditions such as rheumatoid arthritis, lupus, and other autoimmune disorders.
Choice D Reason:
Overactive immune function is not typically associated with chronic stress. Instead, chronic stress often leads to a weakened immune response, making the body more susceptible to infections and illnesses. Therefore, this choice is incorrect.
Choice E Reason:
Cardiovascular disease is a well-documented consequence of chronic stress. The persistent release of stress hormones like adrenaline and cortisol can lead to increased blood pressure, heart rate, and the formation of artery-clogging deposits. These changes can increase the risk of heart disease, heart attacks, and strokes.
