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. Which type of isolation is required for a patient with measles?

• A. Contact isolation
• B. Airborne isolation
• C. Droplet isolation
• D. Reverse isolation

Correct answer: B

Rationale: The correct answer is B: Airborne isolation. Measles is highly contagious and can be transmitted through airborne particles, so airborne isolation is necessary to prevent its spread. Choice A, Contact isolation, is incorrect because measles is not primarily transmitted through direct contact. Choice C, Droplet isolation, is also incorrect as measles is not transmitted through large droplets but through smaller airborne particles. Choice D, Reverse isolation, is used to protect a patient from outside infections, not to prevent the spread of a contagious disease like measles.

3. The PN administered darbepoetin alfa to a client with chronic kidney disease (CKD). Which serum laboratory value should the PN monitor to assess the effectiveness of this drug?

• A. Calcium
• B. Phosphorus
• C. Hemoglobin
• D. White blood cell count

Correct answer: C

Rationale: Darbepoetin alfa is used to stimulate red blood cell production in clients with CKD. Monitoring hemoglobin levels is essential to assess the effectiveness of the treatment and to adjust the dosage to avoid complications such as hypertension or thrombosis. Monitoring calcium (Choice A), phosphorus (Choice B), or white blood cell count (Choice D) is not directly related to the effectiveness of darbepoetin alfa in treating anemia associated with CKD.

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. The home health PN suspects elder abuse after observing fresh lacerations on the arms and legs of an older adult male client who lives with his daughter. Which action is most important for the PN to take?

• A. Document the lacerations in the client's record
• B. Report findings to the supervisor for referral to adult protective services
• C. Ask the daughter who has been taking care of the client on a daily basis
• D. Apply dry dressings after cleansing the wounds

Correct answer: B

Rationale: The most important action for the PN to take in this situation is to report the findings to the supervisor for referral to adult protective services. Suspected elder abuse must be reported promptly to ensure the safety and protection of the client. Documenting the lacerations in the client's record is important but not as critical as reporting the suspected abuse. Asking the daughter who is the potential abuser may not yield accurate information and could compromise the safety of the client. Applying dressings to the wounds is a lower priority compared to addressing the suspected elder abuse.
