Nursing Elites

1. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

2. An adolescent with intellectual disability is admitted for refusing to complete oral hygiene. A behavior modification program is recommended. Which reinforcement is best?

• A. Unit tasks for each omitted teeth brushing.
• B. Candy for each successfully completed hygiene task.
• C. Privilege restriction for refusing hygiene tasks.
• D. Preferred activities or tokens for compliance.

Correct answer: D

Rationale: The best reinforcement strategy in this scenario is providing preferred activities or tokens for compliance. Positive reinforcement is effective in behavior modification programs for individuals with intellectual disabilities. Offering preferred activities or tokens serves as a reward for completing the desired behavior, in this case, oral hygiene tasks. Choices A, B, and C do not focus on reinforcing the desired behavior with positive incentives. Choice A does not provide a positive reinforcement for compliance but rather focuses on the omission of a task. Choice B uses candy, which may not be ideal for oral hygiene. Choice C involves punishment rather than positive reinforcement.

3. After administering a proton pump inhibitor, which action should the nurse take to evaluate the effectiveness of the medication?

• A. Monitor gastrointestinal pain
• B. Ask the client about pain levels
• C. Check the client's vital signs
• D. Assess for signs of bleeding

Correct answer: B

Rationale: The correct answer is to ask the client about pain levels. Proton pump inhibitors (PPIs) work by reducing stomach acid to alleviate gastrointestinal pain. By inquiring about the client's pain experience, the nurse can directly assess the effectiveness of the medication. Monitoring bowel movements (Choice A) is not directly related to evaluating the effectiveness of a PPI. Checking vital signs (Choice C) may not reflect the medication's effectiveness in reducing stomach acid. Assessing for signs of bleeding (Choice D) is important but not the most direct way to evaluate the effectiveness of a PPI.

4. Which of the following statements reflects appropriate teaching to prevent injury in a client with rheumatoid arthritis?

• A. Use heat applications to relieve swelling and stiffness.
• B. Take warm showers before activity.
• C. Use cold packs to relieve joint pain.
• D. Take prescribed anti-inflammatory medications with meals.

Correct answer: C

Rationale: The correct answer is C. Using cold packs to relieve joint pain is appropriate for clients with rheumatoid arthritis as cold therapy is more effective at reducing inflammation and pain in these conditions. Heat applications may exacerbate the symptoms by increasing swelling. Taking warm showers before activity may provide comfort but does not directly address joint pain or prevent injury. While anti-inflammatory medications are commonly prescribed, they are not directly related to preventing injury in clients with rheumatoid arthritis.

5. A client recently started on warfarin therapy. What laboratory value is most important to monitor for this client?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Creatinine level
• D. Blood urea nitrogen (BUN)

Correct answer: B

Rationale: Prothrombin time (PT) is the most important laboratory value to monitor for clients on warfarin therapy. PT helps determine how long it takes blood to clot and ensures the warfarin dose is within the therapeutic range to prevent either excessive bleeding or clotting. Monitoring platelet count is important for assessing the risk of bleeding, but PT is more specific to warfarin therapy. Creatinine level and BUN are indicators of kidney function and are not directly related to warfarin therapy.
