Nursing Elites

1. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

2. A nurse receives a report about a client receiving IV fluids infusing at 125 mL/hr but notes they have only received 80 mL over the last 2 hours. What should the nurse do first?

• A. Check IV tubing for obstruction
• B. Increase the flow rate
• C. Change the IV site
• D. Notify the physician

Correct answer: A

Rationale: The correct first action for the nurse to take is to check the IV tubing for obstruction. This step is crucial in ensuring that the IV fluids are flowing properly and that there are no blockages preventing the correct infusion rate. Increasing the flow rate (Choice B) without confirming the tubing's status could lead to potential complications if there is indeed an obstruction. Changing the IV site (Choice C) is not the priority in this situation unless there are specific clinical indications. Notifying the physician (Choice D) can be done after checking the tubing for obstruction, as the physician may need to be informed depending on the findings.

3. At the surgical scrub sink, a surgical nurse demonstrated the proper surgical handwashing technique by scrubbing:

• A. With her hands held lower than her elbows
• B. With her hands held higher than her elbows
• C. With her hands in a fist position
• D. With hands placed on her chest

Correct answer: B

Rationale: The correct technique for surgical handwashing involves scrubbing with hands held higher than the elbows. This positioning helps prevent water from the contaminated area (the hands) from flowing towards the cleaner area (the elbows). This directional flow minimizes the risk of contaminating the scrubbed hands during the handwashing process. Choices A, C, and D are incorrect: A - having hands lower than elbows would risk contamination of the clean area, C - using a fist position does not ensure proper coverage and thorough handwashing, and D - placing hands on the chest is not part of the proper surgical handwashing technique.

4. A client who has a new prescription for warfarin (Coumadin) is receiving discharge instructions. Which statement indicates the client understands the teaching?

• A. I will take my warfarin at the same time every day.
• B. I should increase my intake of green leafy vegetables.
• C. I should use a soft-bristled toothbrush while taking this medication.
• D. I should avoid drinking alcohol while taking this medication.

Correct answer: C

Rationale: The correct answer is C: 'I should use a soft-bristled toothbrush while taking this medication.' Using a soft-bristled toothbrush is crucial as it helps prevent bleeding gums, which is a potential side effect of warfarin therapy. Option A about taking warfarin at the same time every day is a good practice but does not directly relate to preventing side effects. Option B suggesting an increase in green leafy vegetables can interfere with warfarin's anticoagulant effects due to their vitamin K content. Option D advising to avoid alcohol is generally recommended but is not directly related to the specific side effects of warfarin.

5. The healthcare professional is preparing to administer a medication through a nasogastric (NG) tube. Which action should the healthcare professional take to ensure proper administration?

• A. Flush the tube with 30 ml of water before and after medication administration.
• B. Administer the medication with food to prevent nausea.
• C. Verify tube placement by aspirating stomach contents.
• D. Dilute the medication with normal saline before administration.

Correct answer: A

Rationale: Flushing the NG tube with water before and after medication administration is essential to ensure the tube is patent and prevent clogging. This action helps in clearing the tube and ensures that the medication is delivered properly. Administering medication with food (Choice B) may not be appropriate for all medications and can interfere with their absorption. Verifying tube placement by aspirating stomach contents (Choice C) is important but does not directly relate to ensuring proper medication administration. Diluting the medication with normal saline (Choice D) is not a standard practice for administering medications through an NG tube.
