Nursing Elites

1. A complication of total parenteral nutrition (TPN) is the development of cholestasis. What is this condition?

• A. an inflammatory process of the extrahepatic bile ducts
• B. an arrest of the normal flow of bile
• C. an inflammation of the gallbladder
• D. the formation of gallstones

Correct answer: B

Rationale: Cholestasis due to TPN administration is an intrahepatic process that interrupts the normal flow of bile. It is characterized by a reduction or stoppage of bile flow. Choice A, an inflammatory process of the extrahepatic bile ducts, refers to cholangitis, not cholestasis. Choice C, an inflammation of the gallbladder, describes cholecystitis, a different condition. Choice D, the formation of gallstones, is not correct as cholestasis is about the flow of bile, not the formation of gallstones.

2. Which laboratory test would be the least effective in diagnosing a myocardial infarction?

• A. AST
• B. Troponin
• C. CK-MB
• D. Myoglobin

Correct answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.

3. The healthcare provider recognizes that which of the following would be most appropriate to wear when providing direct care to a client with a cough?

• A. Mask
• B. Gown
• C. Gloves
• D. Shoe covers

Correct answer: A

Rationale: When providing care to a client with a cough, it is crucial to wear a mask to protect oneself from inhaling respiratory droplets containing infectious agents. The primary mode of transmission for coughs is through airborne droplets, making a mask the most appropriate choice to prevent the spread of respiratory infections. Gloves and gowns are more relevant when there is a risk of contact with bodily fluids, which is not the main concern with a cough. Shoe covers are not necessary in this scenario as the transmission of respiratory infections is not linked to footwear. Therefore, wearing a mask is the best choice to prevent airborne transmission and ensure the safety of the healthcare provider.

4. A client with acute leukemia develops a low white blood cell count. In addition to the institution of isolation, the nurse should:

• A. Request that foods be provided in sealed single-serving packages
• B. Ask the client to wear a mask when visitors are present
• C. Prep IV sites with mild soap and water and alcohol
• D. Provide foods in sealed single-serving packages

Correct answer: D

Rationale: For a client with acute leukemia and a low white blood cell count, preventing exposure to food contaminants is crucial due to immune suppression. Providing foods in sealed single-serving packages helps reduce the risk of contamination. Choice B is incorrect as it introduces the potential of infection from visitors. Choice A, suggesting disposable utensils, is not as effective as sealed containers in preventing food contamination. Choice C, using alcohol for prepping IV sites, is less suitable due to its drying effect and potential for skin breakdown, making sealed packages a better option for food safety.

5. The nurse is making assignments for the day. Which client should be assigned to the pregnant nurse?

• A. The client receiving linear accelerator radiation therapy for lung cancer
• B. The client with a radium implant for cervical cancer
• C. The client who has just been administered soluble brachytherapy for thyroid cancer
• D. The client who returned from placement of iridium seeds for prostate cancer

Correct answer: A

Rationale: The pregnant nurse should not be assigned to any client with radioactivity present. The client receiving linear accelerator therapy is the correct choice because the radiation stays in the department, and the client is not radioactive. Choices B, C, and D involve clients who are radioactive or pose a risk due to radioactivity. The client with a radium implant for cervical cancer (choice B) is radioactive, the client who has just been administered soluble brachytherapy for thyroid cancer (choice C) is radioactive for approximately 72 hours, and the client who returned from placement of iridium seeds for prostate cancer (choice D) is also radioactive, especially right after the procedure. These options are not suitable for assignment to the pregnant nurse.
