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. All of the following are posture and body alignment problems EXCEPT:

• A. Kyphosis
• B. Scoliosis
• C. Thrombosis
• D. Lumbar lordosis

Correct answer: C

Rationale: Thrombosis is a condition involving blood clots and is not related to posture or body alignment, unlike kyphosis, scoliosis, and lumbar lordosis, which are spinal alignment issues. Kyphosis refers to excessive outward curvature of the spine, scoliosis is characterized by a sideways curvature of the spine, and lumbar lordosis involves an exaggerated inward curve in the lower back. Thrombosis, on the other hand, is a condition where blood clots form in the blood vessels, not a posture or body alignment problem.

3. What is the most effective method to prevent medication errors during administration?

• A. Relying on memory for medication dosages
• B. Using a bar-code medication administration system
• C. Administering medications as quickly as possible to avoid delays
• D. Allowing another individual to administer medications

Correct answer: B

Rationale: Using a bar-code medication administration system is the best method to prevent medication errors during administration. This system verifies medication details electronically, ensuring that the correct medication is given to the right patient. Relying on memory for medication dosages (choice A) is not recommended as it can lead to errors. Administering medications quickly (choice C) may increase the risk of mistakes due to haste. Allowing another individual (choice D) to administer medications does not address the root cause of preventing errors during administration.

4. The PN assigns a UAP to assist with the personal care of a client experiencing an acute exacerbation of multiple sclerosis. Which instruction should the PN provide the UAP?

• A. Assist the client with a hot bath
• B. Encourage self-care but allow rest periods
• C. Face the client directly when speaking
• D. Keep the head of the bed elevated at all times

Correct answer: B

Rationale: During an acute exacerbation of multiple sclerosis, it is important to encourage self-care to maintain the client's independence. Allowing rest periods helps prevent fatigue, which is crucial in managing MS exacerbations. Choice A is incorrect as hot baths can exacerbate symptoms in MS. Choice C is about communication techniques and not directly related to client care during an exacerbation. Choice D is not a priority intervention during an MS exacerbation.

5. An 8-year-old child is placed in 90-90 traction for a fractured femur. The nurse notices that the weights are touching the foot of the bed. What action should the nurse take?

• A. No bowel movement for two days
• B. Mother helps reposition the child
• C. Ensure weights are not touching the foot of the bed
• D. Child wiggles toes freely when tickled

Correct answer: C

Rationale: The nurse should ensure that the weights in traction are not touching the foot of the bed. This is crucial to maintain proper alignment and effectiveness of the traction. When the weights touch the bed, it can compromise the traction's function and delay healing. Choices A, B, and D are incorrect as they do not address the issue of ensuring that the weights are not touching the bed, which is essential for the traction to work effectively.
