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. What is the most appropriate nursing action when a patient on anticoagulant therapy develops sudden, severe back pain?

• A. Administer pain medication
• B. Apply a cold compress to the back
• C. Assess for signs of internal bleeding
• D. Reposition the patient for comfort

Correct answer: C

Rationale: When a patient on anticoagulant therapy experiences sudden, severe back pain, the priority nursing action is to assess for signs of internal bleeding. Severe back pain in this context could be indicative of internal bleeding, such as a retroperitoneal bleed, which is a critical condition requiring immediate attention. Administering pain medication or applying a cold compress may mask or delay the identification of a potentially life-threatening situation. Repositioning the patient for comfort is not the priority when internal bleeding needs to be ruled out.

3. The PN reviews a client's medication history and learns that the client takes an anticoagulant and has recently started taking phenytoin. Which instruction should the PN provide when assigning the client's morning care to a UAP?

• A. Measure the temperature every 4 hours
• B. Elevate both feet on two pillows
• C. Initiate hourly turning schedule
• D. Protect skin from injury and bruising

Correct answer: D

Rationale: The correct answer is D: Protect skin from injury and bruising. Phenytoin and anticoagulants both increase the risk of bleeding. Protecting the skin from injury and bruising is critical to prevent complications, making it important to instruct the UAP accordingly. Measuring the temperature every 4 hours (Choice A) may not be directly related to the client's medications. Elevating both feet on two pillows (Choice B) is more relevant for issues like edema. Initiating an hourly turning schedule (Choice C) is important for preventing pressure ulcers, but in this case, the priority is to prevent bleeding due to the medications.

4. Based on the computer documentation in the EMR, which action should the PN implement?

• A. Give the rubella vaccine subcutaneously
• B. Observe the mother breastfeeding her infant
• C. Call the nursery for the infant's blood type results
• D. Administer hydrocodone/acetaminophen one tablet for pain

Correct answer: A

Rationale: The rubella vaccine is crucial for preventing rubella infection, which can cause severe congenital disabilities if contracted during pregnancy. Administering the vaccine subcutaneously is the correct action based on EMR documentation. Observing breastfeeding, calling the nursery for blood type results, and administering pain medication are not indicated by the EMR documentation and are not relevant to the situation described in the question.

5. The PN is reviewing instructions for the use of pilocarpine eye drops with a client who has glaucoma. The client replies that the drops are used to anesthetize the eye if eye pain is experienced. What action should the PN implement?

• A. Document in the chart that the client understands the correct action and use of eye drops
• B. Reassure the client that the drops will not be needed often since eye pain in glaucoma is not common
• C. Reteach the client about the action of the eye drops to decrease pressure in the eyes
• D. Explain to the client that the eye drops do not anesthetize the eyes but reduce pressure

Correct answer: C

Rationale: Pilocarpine eye drops are used to reduce intraocular pressure in glaucoma, not to anesthetize the eye. The PN should reteach the client about the purpose of the medication to ensure proper use and understanding, which is crucial for effective treatment. Choice A is incorrect because just documenting understanding without addressing the client's misconception is not enough. Choice B is incorrect as it provides incorrect information about the purpose of the eye drops and may lead to further misunderstanding. Choice D is incorrect as it provides inaccurate information stating that the drops provide pain relief, which is not their primary purpose.
