Nursing Elites

1. A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?

• A. Increase intake of green leafy vegetables
• B. Avoid foods high in vitamin K
• C. Increase intake of foods rich in vitamin C
• D. Limit intake of dairy products

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.

2. A client has a prescription for a Transcutaneous Electrical Nerve Stimulator (TENS) unit for pain management during the postoperative period following a Lumbar Laminectomy. What information should the nurse reinforce about the action of this adjuvant pain modality?

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

Correct answer: A

Rationale: The correct answer is A. TENS units work by delivering small electrical impulses through the skin. These impulses are thought to close the 'gates of nerve conduction,' which can help in managing severe pain. Choice B is incorrect because the dulled pain perception does not occur in the cerebral cortex by the TENS unit. Choice C is incorrect as it describes a different method of pain management involving medication in the spinal canal. Choice D is incorrect because TENS does not work by distracting the client's focus on pain, but rather by altering pain perception through electrical impulses.

3. The nurse is caring for a client with a diagnosis of bipolar disorder who is taking lithium. What is the most important information the nurse should provide?

• A. Take the medication on an empty stomach.
• B. Monitor sodium intake.
• C. Report any signs of weight gain.
• D. Avoid excessive caffeine intake.

Correct answer: B

Rationale: The correct answer is B: 'Monitor sodium intake.' Sodium levels can affect lithium levels in the body, so it is crucial to maintain a consistent sodium intake to prevent toxicity or subtherapeutic levels. Option A is incorrect because lithium is usually recommended to be taken on an empty stomach to enhance absorption. Option C, reporting signs of weight gain, is relevant but not as critical as monitoring sodium intake. Option D, avoiding excessive caffeine intake, is important for some individuals but not as essential as monitoring sodium levels when taking lithium.

4. What is the primary function of neutrophils?

• A. Heparin secretion
• B. Transport oxygen
• C. Phagocytotic action
• D. Antibody formation

Correct answer: C

Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.

5. A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important instruction the nurse should provide?

• A. Take the medication with a high-fiber meal
• B. Monitor pulse rate daily before taking the medication
• C. Avoid dairy products while on this medication
• D. Discontinue the medication if blurred vision is experienced

Correct answer: B

Rationale: The most important instruction the nurse should provide is to monitor pulse rate daily before taking the medication. Digoxin can lead to bradycardia, so it is crucial to assess the pulse rate before administering the medication. This practice helps ensure that the heart rate is not too low for the safe use of digoxin. Choice A is incorrect as there is no specific requirement to take digoxin with a high-fiber meal. Choice C is also incorrect because there is no need to avoid dairy products while on digoxin. Choice D is incorrect since blurred vision is not a common side effect of digoxin; hence, it is not the most critical instruction to provide.
