Nursing Elites

1. 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.

2. A client with diabetes mellitus reports tingling in their feet. What is the nurse's best intervention?

• A. Advise the client to avoid wearing tight shoes.
• B. Refer the client to a podiatrist for foot care.
• C. Teach the client about blood sugar control and foot care.
• D. Administer insulin as prescribed.

Correct answer: C

Rationale: The correct intervention for a client with diabetes mellitus experiencing tingling in their feet is to teach the client about blood sugar control and foot care. This is essential because tingling in the feet can be a sign of neuropathy, a common complication of diabetes. Educating the client on maintaining proper blood sugar levels and foot care practices can help manage neuropathy symptoms and prevent complications like ulcers or infections. Advising the client to avoid tight shoes (Choice A) may help with comfort but does not address the underlying issue. Referring the client to a podiatrist (Choice B) is important for foot care but does not directly address blood sugar control. Administering insulin (Choice D) is not the priority for managing tingling in the feet related to neuropathy.

3. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

4. 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.

5. A client is admitted with a suspected pulmonary embolism (PE). What is the nurse's priority intervention?

• A. Administer anticoagulant therapy as prescribed.
• B. Elevate the head of the bed to 45 degrees.
• C. Check the client's oxygen saturation.
• D. Prepare the client for a CT scan.

Correct answer: D

Rationale: The correct answer is to prepare the client for a CT scan. A CT scan is essential in confirming the presence of a pulmonary embolism (PE) and guiding further treatment. Administering anticoagulant therapy (Choice A) is important in the management of PE, but it is not the priority intervention in this case. Elevating the head of the bed (Choice B) is beneficial for optimizing oxygenation but is not the priority intervention when a PE is suspected. Checking the client's oxygen saturation (Choice C) is important, but obtaining a definitive diagnosis through a CT scan takes precedence in this situation.
