Nursing Elites

1. Which vitamin deficiency is most associated with night blindness?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin D

Correct answer: A

Rationale: The correct answer is Vitamin A. Vitamin A deficiency leads to night blindness because this vitamin is crucial for the formation of rhodopsin, a photopigment in the retina. Rhodopsin is essential for vision in low-light conditions. Vitamin B12 deficiency can lead to anemia and neurological issues but is not directly related to night blindness. Vitamin C deficiency can cause scurvy, affecting connective tissues, but not night vision. Vitamin D deficiency can lead to bone disorders but is not primarily associated with night blindness.

2. In what order should the PN implement these steps to provide wound care? (Place in correct order.)

• A. Don procedure gloves
• B. Remove the dressing
• C. Apply prescribed medications to the wound
• D. All of the Above

Correct answer: D

Rationale: The correct answer is 'D - All of the Above.' The PN should first don procedure gloves to maintain aseptic technique, then remove the dressing to assess the wound, and finally apply prescribed medications to the wound. This sequence ensures that non-sterile tasks like donning gloves are done before sterile tasks like applying medications, reducing the risk of wound contamination. Choices A, B, and C are all essential steps in providing effective wound care.

3. A client confides to the nurse that the client has been substituting herbal supplements for high blood pressure instead of the prescribed medication. How should the nurse respond first?

• A. Ask the client's reason for choosing to take herbs instead of prescribed medication
• B. Reinforce that the healthcare provider prescribed the medication for a reason
• C. Have the client use their own words to describe complications of high blood pressure
• D. Point out the risks of not taking the prescribed medication rather than herbal supplements

Correct answer: A

Rationale: The correct answer is to ask the client's reason for choosing to take herbs instead of prescribed medication. Understanding the client's rationale for using herbal supplements allows the nurse to explore any misconceptions and provide education on the importance of the prescribed medication. Choice B is incorrect because simply reinforcing the prescription does not address the client's concerns or reasons for using herbal supplements. Choice C does not directly address the immediate concern of the client substituting medication with herbal supplements. Choice D focuses on the risks of not taking the prescribed medication rather than herbal supplements, which is not the most appropriate initial response.

4. What is an essential nursing action before administering a blood transfusion?

• A. Checking the patient’s blood pressure
• B. Verifying the blood type and patient identity with another nurse
• C. Flushing the IV line with saline
• D. Administering pre-transfusion medications

Correct answer: B

Rationale: Verifying the blood type and patient identity with another nurse is crucial before administering a blood transfusion. This step helps prevent transfusion reactions and ensures that the correct blood is given to the right patient. Checking the patient’s blood pressure, although important, is not directly related to verifying blood type and patient identity. Flushing the IV line with saline is a good practice but is not as critical as confirming the blood type and patient identity. Administering pre-transfusion medications would come after verifying the blood type and patient identity.

5. Based on the principle of asepsis, which situation should the nurse consider to be sterile?

• A. A one-inch border around the edges of a sterile field set up in the operating room
• B. A sterile glove that the nurse thinks might have touched her hair
• C. A wrapped, unopened sterile 4x4 gauze pad placed on a damp tabletop
• D. An open sterile Foley catheter kit set up on a table at the nurse's waist level

Correct answer: D

Rationale: The correct answer is D because an open sterile Foley catheter kit set up at waist level is considered sterile if it has not been contaminated. Choice A is incorrect because the one-inch border around a sterile field is considered non-sterile. Choice B is incorrect because a sterile glove that might have touched the nurse's hair is likely contaminated. Choice C is incorrect because a wrapped, unopened sterile gauze pad placed on a damp tabletop may have become contaminated.
