A nurse is reviewing the plan of care for a client who is receiving oxygen therapy. Which of the following interventions should the nurse include to prevent complications?

Correct Answer: B

Rationale: The correct answer is B: Provide humidified oxygen. Providing humidified oxygen helps prevent dryness and irritation of the respiratory tract during oxygen therapy. This intervention is crucial in preventing complications such as mucous membrane dryness and potential damage to the airways. Checking the client's oxygen saturation every 2 hours (choice A) is essential for monitoring the client's response to therapy but does not directly prevent complications. Instructing the client to perform deep breathing exercises (choice C) is beneficial for respiratory function but does not directly address preventing complications related to oxygen therapy. Using an oxygen mask for delivery (choice D) is a common method of administering oxygen but does not specifically focus on preventing complications like dryness and irritation.

Correct Answer: D

Rationale: When a charge nurse observes repeated failure in a staff member's performance, it is essential to address the issue directly. Choice D is the correct answer as it involves discussing the behavior with the assistive personnel (AP) while reinforcing expectations. This approach helps in clarifying the expected standards, setting accountability, and providing an opportunity for improvement. Choices A, B, and C are incorrect. Ignoring the behavior (Choice A) does not address the problem and can lead to continued substandard care. Reassigning the AP (Choice B) may not solve the issue and can potentially transfer the problem to another area. Reporting the behavior to the manager (Choice C) without directly addressing it with the AP first may not promote a constructive approach to resolving the issue.

Correct Answer: C

Rationale: The correct answer is C: Previous violent behavior. This is considered the best predictor of future violent actions as individuals who have a history of violent behavior are more likely to engage in violent acts again. Option A, experiencing delusions, although it can impact behavior, is not as strong of a predictor as past violent behavior. Option B, male gender, is a demographic factor but not as specific or predictive as a history of violence. Option D, a history of being in prison, may indicate past behavior but is not directly linked to future violent actions as a known history of violence.

Correct Answer: B

Rationale: The correct answer is B: Potassium. Furosemide is a loop diuretic that can cause potassium depletion through increased urinary excretion. Monitoring potassium levels is crucial to prevent hypokalemia, which can lead to cardiac dysrhythmias, muscle weakness, and other serious complications. Monitoring sodium, calcium, and magnesium levels is not typically associated with furosemide therapy, making choices A, C, and D incorrect.

Correct Answer: C

Rationale: An oxygen saturation of 90% is below the expected reference range and could indicate respiratory depression, a serious side effect of morphine. This finding requires immediate attention as it may lead to hypoxia. Nausea (choice A) is a common side effect of morphine but does not pose an immediate threat. A urinary output of 20 mL/hr (choice B) may indicate decreased renal perfusion but is not as critical as respiratory compromise. A respiratory rate of 14/min (choice D) is within the normal range and does not suggest immediate danger.

Correct Answer: A

Rationale: The correct instruction the nurse should include is to advise the client to avoid crowded places. Immunocompromised clients undergoing chemotherapy are at a higher risk of infections, so avoiding crowded places can help reduce exposure to pathogens. Wearing a mask at home is not necessary unless someone in the household is sick. Drinking unfiltered water can introduce harmful bacteria, increasing the risk of infection. Avoiding washing hands frequently is incorrect as hand hygiene is crucial in preventing the spread of infections.

Correct Answer: A

Rationale: The correct nursing intervention for a patient receiving anticoagulant therapy is to monitor INR levels and check for signs of bleeding. Monitoring the INR levels helps assess the effectiveness and safety of anticoagulant therapy, while checking for bleeding is essential due to the increased risk associated with anticoagulants. Choice B is incorrect as antiplatelet therapy is not the standard treatment for patients on anticoagulant therapy. Choice C is incorrect as providing additional anticoagulation is not a direct nursing intervention in this scenario. Choice D is incorrect because administering aspirin, an antiplatelet medication, along with anticoagulants can increase the risk of bleeding and is generally avoided.

Correct Answer: A

Rationale: Corrected Rationale: Regular monitoring for infection and dressing changes are essential aspects of caring for a patient with a central venous catheter. Infections are a significant risk with these catheters, so vigilant monitoring and timely dressing changes help prevent complications. Choice B is important too, but ensuring catheter patency and flushing are more focused on maintaining the functionality of the catheter rather than infection prevention. Choice C is also important for patient education, but the immediate concern for a healthcare professional is monitoring and preventing infections related to the catheter. Choice D is not directly related to the care of a central venous catheter.

Correct Answer: A

Rationale: When managing a patient with a fever, the appropriate approach involves administering antipyretics to reduce the fever and monitoring the patient's vital signs to assess their response to treatment. Administering antipyretics helps to lower the body temperature and manage fever symptoms effectively. Monitoring vital signs is crucial to ensure the patient's condition is improving. Providing cold compresses, as mentioned in choice B, can help in managing fever symptoms, but it does not address the root cause of the fever. Encouraging the patient to rest, as stated in choice C, is beneficial for recovery, but increasing fluid intake is essential to prevent dehydration. Restricting fluid intake and providing bed rest, as in choice D, can lead to dehydration and hinder the body's ability to fight off the infection causing the fever. Therefore, the best course of action for a healthcare provider is to administer antipyretics while closely monitoring the patient's vital signs.
