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. A client with a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management asks how it works. What information should the nurse reinforce?

• A. The discharge of electricity will distract the client's focus from the pain
• B. An infusion of medication in the spinal canal will block pain perception
• C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
• D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain

Correct answer: D

Rationale: The correct answer is D. TENS works by delivering a mild electrical stimulus that can block pain signals from reaching the brain, effectively reducing the perception of pain. Choice A is incorrect because TENS does not distract from pain but rather interferes with pain signals. Choice B is incorrect as TENS does not involve infusing medication into the spinal canal. Choice C is also incorrect because TENS does not target the cerebral cortex to dull pain perception but rather works at the level of nerve conduction.

3. A client is post-operative day two from a total hip arthroplasty. The nurse notices the surgical wound is red and warm to the touch. What is the most appropriate action?

• A. Apply an ice pack to the incision site.
• B. Monitor the client's temperature.
• C. Document the findings and continue to monitor.
• D. Notify the healthcare provider.

Correct answer: D

Rationale: The correct action when a nurse notices redness and warmth at the surgical wound post total hip arthroplasty is to notify the healthcare provider. These signs may indicate an infection, and prompt evaluation by the healthcare provider is crucial to initiate appropriate treatment. Applying an ice pack (Choice A) may not address the underlying issue of a potential infection. Monitoring the client's temperature (Choice B) is important but not the priority when signs of infection are present. Documenting the findings and continuing to monitor (Choice C) is necessary but should be accompanied by notifying the healthcare provider for further assessment and intervention.

4. The PN is reviewing care instructions with a client who has diabetic retinopathy and is experiencing glare around lights. What should the PN reinforce with the client?

• A. Cover eyes with moist, cool compresses to reduce glare
• B. Make adjustments to personal schedule to avoid driving at night
• C. Exert pressure on the inner canthus when tearing occurs
• D. Apply an eye shield at bedtime after instilling eye drops

Correct answer: B

Rationale: The correct answer is B. Avoiding driving at night is recommended for clients experiencing glare around lights due to diabetic retinopathy. This can help reduce the risk of accidents and visual discomfort. Making adjustments to the personal schedule to avoid nighttime driving is a practical approach to manage the glare. Choices A, C, and D are incorrect because covering eyes with compresses, exerting pressure on the inner canthus, or applying an eye shield are not effective strategies for managing glare associated with diabetic retinopathy.

5. The PN is caring for an older client who was informed about the diagnosis of terminal cancer two days ago. Which intervention would be most helpful for the client's spouse at this time?

• A. Consultation with the case manager and hospital chaplain
• B. Visiting after procedures are done to avoid seeing the client in pain
• C. Participating in the client's care within his/her capabilities and desires
• D. Information about palliative and hospice care services

Correct answer: D

Rationale: Providing information about palliative and hospice care services can help the spouse understand the options for managing the client's symptoms and improving the quality of life. This also provides support and guidance during a difficult time. Consulting with the case manager and hospital chaplain may be beneficial for emotional support but may not address the practical aspects of care. Visiting after procedures are done to avoid seeing the client in pain may not foster open communication and support. While participating in the client's care is important, providing information about palliative and hospice care services is the most helpful intervention in this scenario.
