Nursing Elites

1. What is the proper technique for obtaining a blood specimen from a central venous line?

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

2. A client has a prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include in the teaching?

• A. Place the tablet under the tongue and wait 10 minutes
• B. Take up to five tablets during an angina episode
• C. Take up to three tablets during a single angina episode
• D. Swallow the tablet with water

Correct answer: C

Rationale: The correct answer is C: 'Take up to three tablets during a single angina episode.' Nitroglycerin can be taken up to three times during an episode to relieve angina. Choice A is incorrect because the client should place the tablet under the tongue and wait for it to dissolve, not wait for 10 minutes. Choice B is incorrect because taking up to five tablets during an angina episode is excessive and not recommended. Choice D is incorrect because nitroglycerin tablets are meant to be taken sublingually, not swallowed.

3. What is the first step when administering a blood transfusion?

• A. Warm the blood to body temperature
• B. Verify the client's blood type before administration
• C. Administer the blood through an IV push
• D. Administer diuretics before the transfusion

Correct answer: B

Rationale: The correct answer is to verify the client's blood type before administration. This step is crucial to ensure compatibility and prevent adverse reactions such as hemolytic transfusion reactions. Warming the blood to body temperature (Choice A) is not the first step and is not typically done during blood transfusions. Administering the blood through an IV push (Choice C) is incorrect as blood transfusions are usually administered as a slow infusion. Administering diuretics before the transfusion (Choice D) is unnecessary and not a standard practice when initiating a blood transfusion.

4. A client has a history of oliguria, hypertension, and peripheral edema. Current lab values are: BUN - 25, K+ - 4.0 mEq/L. Which nutrient should be restricted in the client's diet?

• A. Protein
• B. Fats
• C. Carbohydrates
• D. Magnesium

Correct answer: A

Rationale: In clients with oliguria, hypertension, and peripheral edema, protein should be restricted in the diet to reduce the workload on the kidneys. Excessive protein intake can lead to increased BUN levels, which can further stress the kidneys. Restricting protein can help prevent further kidney damage. Fats, carbohydrates, and magnesium do not directly impact kidney function in the same way as protein does, making them incorrect choices in this scenario.

5. A healthcare professional is caring for a client with coronary artery disease (CAD) who is prescribed aspirin. Which of the following findings should the healthcare professional report to the provider?

• A. A history of gastrointestinal bleeding
• B. A history of hypertension
• C. A platelet count of 180,000/mm³
• D. A prothrombin time (PT) of 12 seconds

Correct answer: A

Rationale: The correct answer is A: A history of gastrointestinal bleeding. Patients with a history of gastrointestinal bleeding are at increased risk of complications when taking aspirin due to its effects on platelet function and the gastrointestinal tract. Reporting this finding to the provider is crucial to ensure patient safety. Choices B, C, and D are not directly related to the increased risk associated with aspirin use in patients with a history of gastrointestinal bleeding, making them less relevant in this scenario. While monitoring platelet count and PT are important in patients taking aspirin, a history of gastrointestinal bleeding takes precedence as it directly impacts the safety and effectiveness of aspirin therapy in this client.
