Nursing Elites

1. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

• A. high HDL cholesterol
• B. low HDL cholesterol
• C. low total cholesterol
• D. low triglycerides

Correct answer: B

Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (Choice B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (Choice C) and low triglycerides (Choice D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.

2. The nurse is teaching a client about communicable diseases and explains that a portal of entry is:

• A. a vector.
• B. a source, like contaminated water.
• C. food.
• D. the respiratory system.

Correct answer: D

Rationale: The correct answer is 'the respiratory system.' A portal of entry is the path through which a microorganism enters the body. In the case of communicable diseases, the respiratory system can serve as a portal of entry for pathogens such as viruses or bacteria. Choices A, B, and C are incorrect. A 'vector' is an organism that transmits disease, not the entry point for pathogens. Contaminated water or food can act as sources or reservoirs of disease-causing microorganisms, not portals of entry.

3. A nurse monitoring a client with a chest tube notes that there is no tidaling of fluid in the water seal chamber. After further assessment, the nurse suspects that the client's lung has reexpanded and notifies the healthcare provider. The healthcare provider verifies with the use of a chest x-ray that the lung has reexpanded, then calls the nurse to ask that the chest tube be removed. Which action should the nurse take first?

• A. Explain the procedure to the client, then remove the chest tube.
• B. Call the nursing supervisor.
• C. Inform the healthcare provider that removal of a chest tube is not a nursing procedure.
• D. Obtain petrolatum-impregnated gauze and ask another nurse to assist in removing the chest tube.

Correct answer: C

Rationale: The correct action for the nurse to take first is to inform the healthcare provider that removal of a chest tube is not a nursing procedure. Actual removal of a chest tube is the duty of a healthcare provider. If the healthcare provider insists that the nurse remove the tube, the nurse must contact the nursing supervisor. Some agencies' policies and procedures may permit an advanced practice nurse to remove a chest tube, but there is no information in the question to indicate that the nurse is an advanced practice nurse. Choice A is incorrect because the nurse should not proceed with removing the chest tube without proper authorization. Choice B is incorrect as calling the nursing supervisor should come after clarifying with the healthcare provider. Choice D is incorrect as the nurse should not begin the process of removing the chest tube without proper guidance and authorization.

4. The nurse notes that a healthcare provider has documented the following prescription in a client's record: Furosemide (Lasix) 40 mg stat once. What action should the nurse take?

• A. Administering the medication
• B. Drawing up the medication in a syringe
• C. Planning to have the nurse on the next shift administer the medication
• D. Contacting the healthcare provider

Correct answer: D

Rationale: The correct action for the nurse to take in this situation is to contact the healthcare provider. The prescription provided lacks crucial information such as the route of administration. Before administering any medication, the nurse must clarify any missing details with the provider, especially for a stat prescription that requires immediate administration. Drawing up or administering the medication without verifying the route of administration is unsafe and can lead to errors. Planning for the next shift nurse to administer the medication is not appropriate in this scenario as the stat order necessitates immediate action. Therefore, the best course of action is to contact the healthcare provider to obtain clarification on the prescription.

5. A client is on a clear liquid diet. She drinks half of a 12-ounce juice, 4 ounces of soup, and has a 6-ounce JELLO�. How many milliliters of fluid did the patient ingest?

• A. 440 ml
• B. 480 ml
• C. 220 ml
• D. 660 ml

Correct answer: B

Rationale: To calculate the total amount of fluid ingested, convert the ounces to milliliters. Given that 1 ounce is equal to 30 ml, the breakdown is as follows: Juice (6 ounces): 6 x 30 = 180 ml. Soup (4 ounces): 4 x 30 = 120 ml. JELLO� (6 ounces): 6 x 30 = 180 ml. Adding these together: 180 ml (juice) + 120 ml (soup) + 180 ml (JELLO�) = 480 ml. Therefore, the patient ingested a total of 480 ml of fluid. It's important to note that gelatin, ice cream, and similar items that are liquid at room temperature should be considered as fluids. Choice A, 440 ml, is incorrect as it does not account for the correct calculation. Choice C, 220 ml, is incorrect as it is significantly lower than the correct total. Choice D, 660 ml, is incorrect as it overestimates the total fluid intake.
