Nursing Elites

1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

2. The healthcare provider prescribes a diet high in vitamin C for a client with a leg wound. Which food should the nurse encourage the client to eat?

• A. Bananas and pineapple
• B. Cottage cheese and crackers
• C. Peanut butter and jelly
• D. Tomato and lettuce salad

Correct answer: D

Rationale: Tomatoes and lettuce are high in vitamin C, making them suitable choices for a diet prescribed for wound healing. Bananas and pineapple (Choice A) are not particularly high in vitamin C compared to tomatoes and lettuce. Cottage cheese and crackers (Choice B) as well as peanut butter and jelly (Choice C) do not provide significant amounts of vitamin C, which is essential for wound healing.

3. A client who is HIV positive and taking lamivudine (Epivir) calls the clinic to report a cough and fever. What action should the nurse implement?

• A. Advise the client to come to the clinic for an evaluation
• B. Advise the client to increase fluid intake
• C. Advise the client to take an over-the-counter cough suppressant
• D. Advise the client to rest and call if the fever persists

Correct answer: A

Rationale: The correct action for the nurse to implement in this situation is to advise the client to come to the clinic for an evaluation. Given the client's HIV-positive status and medication, it is crucial to assess the cough and fever promptly to identify the underlying cause. Increasing fluid intake (choice B) may be beneficial but does not address the need for evaluation. Taking an over-the-counter cough suppressant (choice C) may not be appropriate without knowing the cause of the symptoms. Advising the client to rest and call if the fever persists (choice D) delays the necessary evaluation and treatment.

4. The nurse believes that a client who frequently requests pain medication may have a substance abuse problem. Which intervention reflects the nurse's value of client autonomy over veracity?

• A. Administer the prescribed analgesic when requested
• B. Enroll the client in a substance abuse program
• C. Collaborate with the healthcare provider to provide a placebo
• D. Document the frequency of medication requests

Correct answer: A

Rationale: Administering the prescribed analgesic when requested reflects the nurse's value of client autonomy over veracity. This choice respects the client's right to manage their pain as they see fit. Enrolling the client in a substance abuse program (Choice B) assumes substance abuse without evidence and infringes on the client's autonomy. Providing a placebo (Choice C) violates the principle of beneficence and autonomy by deceiving the client. Documenting the frequency of medication requests (Choice D) is important for assessment but does not directly address the client's autonomy in managing their pain.

5. The nurse is preparing to administer medications to a client with a nasogastric tube. Which action should the nurse take first?

• A. Check for tube placement
• B. Crush the medications
• C. Flush the tube with water
• D. Administer the medications

Correct answer: A

Rationale: The correct first action when administering medications to a client with a nasogastric tube is to check for tube placement. This is crucial to ensure that the medications are delivered to the correct location within the gastrointestinal tract. Checking the tube placement helps prevent complications such as medication entering the lungs if the tube is misplaced. Crushing the medications (choice B) or flushing the tube with water (choice C) should only be done after confirming the correct tube placement. Administering the medications (choice D) without verifying the tube placement can lead to serious consequences.
