Nursing Elites

1. A nurse is caring for a client who has tuberculosis. Which of the following precautions should the nurse plan to implement when working with the client?

• A. Airborne
• B. Droplet
• C. Protective
• D. Contact

Correct answer: A

Rationale: Tuberculosis is an infectious disease that requires airborne precautions to prevent the transmission of infectious droplets. Airborne precautions involve wearing a mask, such as an N95 respirator, to protect against inhaling infectious particles. Droplet precautions are for diseases spread through respiratory droplets larger than those in airborne transmission, such as influenza. Protective precautions are not specific to respiratory infections and are more general measures to protect patients from harm. Contact precautions are used for diseases spread by direct or indirect contact, such as MRSA or C. diff infections, not for tuberculosis.

2. 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.

3. A healthcare professional is preparing to administer 750 mL of 0.9% sodium chloride IV to infuse over 7 hr. The professional should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 107 mL/hr
• B. 120 mL/hr
• C. 95 mL/hr
• D. 100 mL/hr

Correct answer: A

Rationale: To calculate the infusion rate, divide the total volume (750 mL) by the total time (7 hr). 750 ÷ 7 ≈ 107 mL/hr. Choice A is correct because it accurately calculates the infusion rate based on the total volume and time. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate in this scenario.

4. While administering a cleansing enema, the client reports abdominal cramping. Which of the following actions should the nurse take?

• A. Have the client hold their breath briefly and bear down.
• B. Clamp the enema tubing.
• C. Remind the client that cramping is common at this time.
• D. Raise the level of the enema fluid container.

Correct answer: C

Rationale: When a client reports abdominal cramping during a cleansing enema, it is important for the nurse to reassure the client that cramping is a common side effect. This reassurance helps the client understand that the cramping is normal and may subside once the enema is completed. Instructing the client to hold their breath and bear down (Choice A) is not appropriate and may cause discomfort. Clamping the enema tubing (Choice B) is unnecessary and could lead to complications. Raising the level of the enema fluid container (Choice D) does not address the client's discomfort due to cramping. Therefore, the most suitable action is to provide reassurance to the client about the common occurrence of cramping during the enema.

5. When lifting a bedside cabinet to move it closer to a client who is sitting in a chair, which of the following actions should the nurse take to prevent self-injury?

• A. Bend at the waist
• B. Keep feet close together
• C. Use back muscles for lifting
• D. Stand close to the cabinet when lifting it

Correct answer: D

Rationale: The correct answer is to stand close to the cabinet when lifting it. This action keeps the object close to the nurse's center of gravity, reducing the risk of back strain. Bending at the waist (Choice A) can increase the risk of back injury as it puts strain on the lower back. Keeping feet close together (Choice B) does not provide a stable base of support for lifting a heavy object. Using back muscles for lifting (Choice C) is incorrect as it can lead to back strain and injury. Therefore, standing close to the cabinet when lifting it is the safest and most effective approach to prevent self-injury.
