Nursing Elites

1. The nurse is providing discharge teaching to a client with a new prescription for warfarin (Coumadin). Which dietary instruction should the nurse include?

• A. Avoid foods high in vitamin K
• B. Increase intake of leafy green vegetables
• C. Consume a consistent amount of foods high in potassium
• D. Limit intake of high-protein foods

Correct answer: A

Rationale: The correct dietary instruction for a client taking warfarin is to avoid foods high in vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consuming foods high in vitamin K, such as leafy green vegetables, can antagonize the effects of warfarin, potentially leading to treatment inefficacy or fluctuations in anticoagulation levels. Therefore, clients on warfarin therapy should be advised to avoid foods high in vitamin K to maintain the effectiveness of the medication. Choices B, C, and D are incorrect because increasing leafy green vegetables (choice B) would introduce more vitamin K, consuming a consistent amount of foods high in potassium (choice C) is not directly related to warfarin therapy, and limiting high-protein foods (choice D) is not a specific concern for clients on warfarin therapy.

2. The health care provider has changed a client's prescription from the PO to the IV route of administration. The nurse should anticipate which change in the pharmacokinetic properties of the medication?

• A. The client will experience increased tolerance to the drug's effects and may need a higher dose.
• B. The onset of action of the drug will occur more rapidly, resulting in a more rapid effect.
• C. The medication will be more highly protein-bound, increasing the duration of action.
• D. The therapeutic index will be increased, placing the client at greater risk for toxicity.

Correct answer: B

Rationale: When a medication is administered via the IV route, the absorptive process is bypassed, leading to a more rapid onset of action. This results in a faster effect of the drug. Choice A is incorrect because changing the route of administration does not necessarily lead to increased tolerance or the need for a higher dose. Choice C is incorrect as changing the route of administration does not directly affect the protein binding of a medication. Choice D is incorrect because increasing the therapeutic index would actually reduce the risk of toxicity, not increase it.

3. When assessing for orthostatic hypotension during blood pressure measurement, what action should the nurse implement first?

• A. Position the client supine for a few minutes
• B. Assist the client to stand at the bedside
• C. Apply the blood pressure cuff securely
• D. Record the client’s pulse rate and rhythm

Correct answer: A

Rationale: When assessing for orthostatic hypotension, the initial step is to position the client supine for a few minutes. This allows the body to adjust to the supine position before assessing blood pressure changes that may indicate orthostatic hypotension. By observing the blood pressure after the client has rested supine, the nurse can accurately assess for any drop in blood pressure upon standing, which is indicative of orthostatic hypotension. Choices B, C, and D are incorrect as they do not address the initial step in assessing for orthostatic hypotension, which is ensuring the client is positioned correctly to detect blood pressure changes upon standing.

4. The healthcare provider is caring for a client diagnosed with type 2 diabetes mellitus. Which intervention should the healthcare provider implement to assess the client’s glycemic control?

• A. Monitor fasting blood glucose levels
• B. Check urine for ketones
• C. Evaluate hemoglobin A1c levels
• D. Assess the client’s dietary intake

Correct answer: C

Rationale: Evaluating hemoglobin A1c levels is the most appropriate intervention to assess glycemic control in a client with type 2 diabetes mellitus. Hemoglobin A1c levels reflect the average blood glucose control over the past 2-3 months, providing valuable information for monitoring and managing diabetes. Monitoring fasting blood glucose levels (Choice A) is important for daily management but does not provide a long-term view like hemoglobin A1c. Checking urine for ketones (Choice B) is more relevant for assessing diabetic ketoacidosis. Assessing dietary intake (Choice D) is crucial for overall diabetes management but does not directly assess glycemic control.

5. During a sterile procedure at a client's bedside, a healthcare provider contaminates a sterile glove and the sterile field. What is the best action for the nurse to implement?

• A. Report the incident to the supervisor for aseptic technique violation.
• B. Allow the completion of the procedure.
• C. Inquire about the contamination of the glove and sterile field.
• D. Identify the breach in surgical asepsis and provide a new set of sterile supplies.

Correct answer: D

Rationale: In the scenario where a healthcare provider contaminates a sterile glove and the sterile field during a procedure, it is crucial to identify any breach in surgical asepsis. Any potential contamination should be considered compromised, and the nurse must act promptly to maintain sterility by providing a fresh set of sterile supplies for the procedure to continue safely.
