Nursing Elites

1. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

• A. External light sources may cause falsely high oximetry values
• B. A bright light in the client's face may cause a low pulse oximetry
• C. External light sources may cause falsely low oximetry values
• D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.

2. A client is admitted with the diagnosis of pulmonary embolism. While taking a history, the client tells the nurse he was admitted for the same thing twice before, the last time just 3 months ago. The nurse would anticipate the healthcare provider ordering:

• A. Pulmonary embolectomy
• B. Vena caval interruption
• C. Increasing the coumadin therapy to achieve an INR of 3-4
• D. Thrombolytic therapy

Correct answer: B

Rationale: In the case of a client with a history of recurrent pulmonary embolism or contraindications to heparin, vena caval interruption may be necessary. Vena caval interruption involves placing a filter device in the inferior vena cava to prevent clots from traveling to the pulmonary circulation. Pulmonary embolectomy is a surgical procedure to remove a clot from the pulmonary artery, which is usually considered in severe or life-threatening cases. Increasing coumadin therapy to achieve a higher INR may be an option but vena caval interruption would be more appropriate in this scenario. Thrombolytic therapy is used in acute cases of pulmonary embolism to dissolve the clot rapidly, but in a recurrent case with contraindications to anticoagulants, vena caval interruption would be a preferred intervention.

3. The clinic nurse teaches a patient with a 42 pack-year history of cigarette smoking about lung disease. Which information will be most important for the nurse to include?

• A. Options for smoking cessation
• B. Reasons for annual sputum cytology testing
• C. Erlotinib (Tarceva) therapy to prevent tumor risk
• D. Computed tomography (CT) screening for lung cancer

Correct answer: A

Rationale: The most critical information for the nurse to provide to a patient with a significant smoking history is options for smoking cessation. Smoking is the primary cause of lung cancer, making smoking cessation essential in reducing the risk of developing the disease. Annual sputum cytology testing is not a standard screening test for lung cancer; instead, CT scanning is being explored for this purpose. Erlotinib therapy is used in lung cancer treatment but not for preventing tumor risk in individuals without cancer. CT screening for lung cancer is still under investigation and is not primarily aimed at prevention but rather early detection in high-risk individuals.

4. What information should be collected when assessing the health status of a community?

• A. Air pollution levels
• B. Number of health food stores
• C. Most common causes of death
• D. Education level of the individuals

Correct answer: C

Rationale: When assessing the health status of a community, it is crucial to gather data on various health measures such as the most common causes of death. This information helps in understanding the prevalent health issues within the community. Factors like air pollution levels, the number of health food stores, and the education level of individuals are important community aspects but do not directly reflect the health status of the community. Therefore, the correct answer is to collect data on the most common causes of death as it provides insights into the major health concerns affecting the community.

5. What ethical principle has led to the need for informed consent?

• A. Autonomy
• B. Justice
• C. Fidelity
• D. Beneficence

Correct answer: A

Rationale: Autonomy is the ethical principle that emphasizes an individual's right to make their own decisions if they are mentally competent. Informed consent is a direct result of this principle, as it ensures that patients are fully informed before agreeing to any medical intervention. Autonomy is crucial in healthcare as it respects patients' rights and promotes self-determination. Justice, fidelity, and beneficence are important ethical principles in healthcare, but they do not directly lead to the need for informed consent. Justice focuses on fairness and equal treatment, fidelity on trustworthiness and loyalty, and beneficence on doing good for the patient's benefit.
