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. What is the first priority for a patient in respiratory distress?

• A. Administer oxygen
• B. Assess airway patency
• C. Monitor oxygen saturation
• D. Call for assistance

Correct answer: A

Rationale: The correct answer is to administer oxygen. In a patient experiencing respiratory distress, the primary concern is ensuring an adequate oxygen supply to the body. By administering oxygen, you can help improve oxygenation, which is crucial for the patient's overall well-being. Assessing airway patency is important but administering oxygen takes precedence as it directly addresses the oxygenation concern. Monitoring oxygen saturation is also essential, but the immediate action should be to provide oxygen. Calling for assistance can be important but is not the first priority when dealing with a patient in respiratory distress.

3. A nurse on an acute unit has received a change of shift report for 4 clients. Which of the following clients should the nurse assess first?

• A. A client who is 1 hr postoperative and has hypoactive bowel sounds.
• B. A client who has a fractured left tibia and pallor in the affected extremity.
• C. A client who had a cardiac catheterization 3 hr ago and has 3+ pedal pulses.
• D. A client who has an elevated AST level following the administration of azithromycin.

Correct answer: B

Rationale: The correct answer is B because pallor in an extremity after a fracture could indicate compromised circulation, making it a priority for assessment. Choice A is not the priority as hypoactive bowel sounds in a client 1 hr postoperative, while concerning, do not indicate a life-threatening condition. Choice C, a client who had a cardiac catheterization 3 hr ago and has 3+ pedal pulses, indicates good perfusion and does not require immediate attention. Choice D, a client with an elevated AST level following the administration of azithromycin, may require further assessment but is not as urgent as the client with potential compromised circulation in choice B.

4. A nurse is reviewing the medical record of a client who is receiving warfarin for atrial fibrillation. Which of the following findings should the nurse report to the provider?

• A. International normalized ratio (INR) of 2.5
• B. Platelet count of 180,000/mm³
• C. Prothrombin time (PT) of 12 seconds
• D. Partial thromboplastin time (PTT) of 30 seconds

Correct answer: C

Rationale: A prothrombin time (PT) of 12 seconds is below the therapeutic range for warfarin and indicates a need for dosage adjustment. The correct answer is C. A normal International normalized ratio (INR) for a client on warfarin therapy is usually between 2.0 to 3.0; therefore, an INR of 2.5 is within the expected range. A platelet count of 180,000/mm³ is within the normal range (150,000 to 450,000/mm³) and does not require immediate reporting. A partial thromboplastin time (PTT) of 30 seconds is also within the normal range (25-35 seconds) and does not indicate a need for urgent action.

5. A client with active tuberculosis is receiving discharge instructions. Which statement by the client indicates an understanding of the teaching?

• A. I will continue taking my isoniazid until I am no longer contagious.
• B. I should take my prescribed medication for at least 6 months.
• C. I will need to have a TB skin test every 3 months.
• D. I should wear a mask at all times.

Correct answer: B

Rationale: The correct answer is B because the client should take antitubercular medications for a minimum of 6 months to ensure complete eradication of the infection. Choice A is incorrect as stopping the medication early can result in treatment failure and development of drug-resistant TB. Choice C is incorrect as regular TB skin tests are not needed once the client has been diagnosed and treated. Choice D is incorrect as wearing a mask at all times is not necessary for a client with active TB; proper cough etiquette should be followed instead.
