Nursing Elites

1. 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.

2. Which of the following is an example of libel?

• A. A client overhears a nurse telling her assistant that he is 'too high maintenance.'
• B. A client reads disparaging remarks that a nurse has written about him in his chart.
• C. A nurse fails to notify a physician when a client's hemoglobin level is 8.1 gm/dL.
• D. A nurse administers narcotic pain medication to a client in pain but does not have an order.

Correct answer: B

Rationale: Libel involves making defamatory statements against another person in written form. These statements can harm the person's reputation or feelings. In this scenario, the correct answer is when a client reads disparaging remarks that a nurse has written about him in his chart. This constitutes libel because the negative remarks are written down and can potentially damage the client's reputation. Choices A, C, and D do not involve libel. Choice A describes a verbal statement, not written, so it does not constitute libel. Choice C involves a failure to notify a physician, which is a different issue unrelated to libel. Choice D pertains to administering medication without an order, which is a matter of improper practice rather than libel.

3. A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?

• A. A non-rebreather can provide an FiO2 of 40%.
• B. A client should breathe through his or her mouth when using a non-rebreather.
• C. A non-rebreather offers a reservoir from which the client inhales.
• D. The mask of a non-rebreather should be changed every 3 hours.

Correct answer: A

Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.

4. Which of the following nursing interventions is appropriate for a client suffering from a fever?

• A. Avoid withholding food from the client
• B. Increase the client's fluid intake
• C. Provide oxygen
• D. All answers are correct

Correct answer: B

Rationale: The appropriate nursing intervention for a client suffering from a fever is to increase the client's fluid intake. A fever can elevate the body's metabolism, leading to increased breathing and heart workload. This can result in fluid loss due to heightened respiration and sweating. Moreover, the augmented heart workload may necessitate more oxygen to maintain tissue perfusion. Providing oxygen and increasing fluid intake help meet the body's heightened demands during a fever. Withholding food from the client is inappropriate as proper nutrition is crucial for recovery, and providing oxygen alone may not address the fluid and metabolic demands associated with fever. Therefore, the correct choice is to increase the client's fluid intake.

5. The nurse practicing in a maternity setting recognizes that the postmature fetus is at risk due to:

• A. Excessive fetal weight
• B. Low blood sugar levels
• C. Depletion of subcutaneous fat
• D. Progressive placental insufficiency

Correct answer: D

Rationale: A postmature or postterm pregnancy occurs when a pregnancy exceeds the typical term of 38 to 42 weeks. In this situation, the fetus is at risk due to progressive placental insufficiency. This occurs because the placenta loses its ability to function effectively after 42 weeks. The accumulation of calcium deposits in the placenta reduces blood perfusion, oxygen supply, and nutrient delivery to the fetus, leading to potential growth problems. Choices A, B, and C are incorrect because excessive fetal weight, low blood sugar levels, and depletion of subcutaneous fat are not the primary risks associated with postmature fetuses. The main concern lies in the compromised placental function and its impact on fetal well-being.
