Nursing Elites

1. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?

• A. 8 mL/hr
• B. 10 mL/hr
• C. 12 mL/hr
• D. 15 mL/hr

Correct answer: A

Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.

2. A healthcare professional is planning to collect a liquid stool specimen from a client for ova and parasites. Inaccurate test results may result if the healthcare professional:

• A. Refrigerates the collected specimen
• B. Collects the specimen in a sterile container
• C. Delays the collection of the specimen
• D. Uses a non-contaminated collection container

Correct answer: A

Rationale: Refrigeration can kill the ova and parasites present in the stool specimen, leading to inaccurate test results. Storing the specimen in a cold environment can disrupt the integrity of the parasites and ova, affecting the accuracy of the test. Collecting the specimen in a sterile container (Choice B) is the correct procedure to prevent external contamination. Delaying the collection of the specimen (Choice C) may affect the freshness of the sample but does not directly impact the test results. Using a non-contaminated collection container (Choice D) is essential to maintain the sample's integrity but does not relate to the risk of killing ova and parasites through refrigeration.

3. What is the most important action for preventing infection in a client with a central venous catheter?

• A. Changing the catheter dressing every 72 hours.
• B. Flushing the catheter with heparin solution daily.
• C. Ensuring the catheter is clamped when not in use.
• D. Maintaining sterile technique when handling the catheter.

Correct answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. This action helps minimize the introduction of pathogens into the catheter site, reducing the risk of contamination and subsequent infection. Changing the catheter dressing every 72 hours, while important, does not directly address the prevention of infection at the insertion site. Flushing the catheter with heparin solution daily helps prevent occlusion but does not primarily focus on infection prevention. Ensuring the catheter is clamped when not in use is essential for preventing air embolism but does not directly relate to infection control.

4. While caring for a client who is postoperative and has refused to use an incentive spirometer following major abdominal surgery, what is the nurse's priority action?

• A. Request that a respiratory therapist discuss the technique for using the incentive spirometer
• B. Determine the reasons why the client is refusing to use the incentive spirometer
• C. Document the client's refusal to participate in health restorative activities
• D. Administer a pain medication to the client

Correct answer: B

Rationale: The nurse's priority is to determine the reasons why the client is refusing to use the incentive spirometer. By understanding the client's concerns or barriers, the nurse can address them appropriately. Requesting a respiratory therapist (Choice A) may be necessary later but is not the priority. Documenting the refusal (Choice C) is important but does not address the immediate need to assess and intervene. Administering pain medication (Choice D) without addressing the root cause of refusal is not appropriate and may mask the issue rather than resolve it.

5. A client with Guillain-Barre syndrome is in a non-responsive state, yet vital signs are stable and breathing is independent. What should the nurse document to most accurately describe the client's condition?

• A. Comatose, breathing unlabored
• B. Glasgow Coma Scale 8, respirations regular
• C. Appears to be sleeping, vital signs stable
• D. Glasgow Coma Scale 13, no ventilator required

Correct answer: B

Rationale: A client with Guillain-Barre syndrome in a non-responsive state with stable vital signs and independent breathing would most accurately be described by a Glasgow Coma Scale of 8 with regular respirations. Choice A is incorrect as 'comatose' implies a deeper level of unconsciousness than described in the scenario. Choice C is incorrect as 'appears to be sleeping' is not an accurate description of a non-responsive state. Choice D is incorrect as a Glasgow Coma Scale of 13 indicates a higher level of consciousness than stated in the scenario.
