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. The nurse is caring for a client with a chest tube following surgery. The nurse should intervene if which of the following is observed?

• A. The chest tube is securely taped at the insertion site.
• B. The water seal chamber is filled to the correct level.
• C. The chest drainage system is below chest level.
• D. There are no air leaks in the system.

Correct answer: C

Rationale: The correct answer is C. The chest drainage system should always be kept below chest level to ensure proper drainage. Having the system above chest level can result in ineffective drainage. Choices A, B, and D are all correct actions to maintain the integrity and functionality of the chest tube system. Securing the chest tube at the insertion site, maintaining the water seal chamber at the correct level, and ensuring there are no air leaks are all essential components of caring for a client with a chest tube post-surgery.

3. A client with diabetes mellitus is experiencing hyperglycemia. What laboratory value should the nurse monitor to evaluate long-term glucose control?

• A. Blood glucose level
• B. Glycosylated hemoglobin (A1C)
• C. Urine output
• D. Serum ketone level

Correct answer: B

Rationale: The correct answer is B: Glycosylated hemoglobin (A1C). Glycosylated hemoglobin reflects long-term glucose control over the past three months. Monitoring blood glucose levels provides information on the current glucose status and immediate control, but it does not give a comprehensive view of long-term control. Urine output and serum ketone levels are important indicators for other aspects of diabetes management, such as hydration status and ketone production during hyperglycemic episodes, but they do not directly reflect long-term glucose control.

4. In monitoring tissue perfusion in a client following an above the knee amputation (AKA), which action should the nurse include in the plan of care?

• A. Evaluate closest proximal pulse.
• B. Note amount and color of wound drainage.
• C. Observe for swelling around the stump.
• D. Assess skin elasticity of the stump.

Correct answer: A

Rationale: After an amputation, monitoring the pulse closest to the stump is crucial in evaluating tissue perfusion and the overall health of the limb. Swelling and changes in perfusion can indicate complications such as blood clots or infection. Assessing the proximal pulse helps the nurse ensure adequate blood flow to the remaining limb, thereby preventing further complications. Choices B, C, and D are less directly related to monitoring tissue perfusion in this scenario and are more focused on wound healing and stump care.

5. A client with diabetic ketoacidosis (DKA) is receiving an insulin infusion. Which finding indicates that the treatment is effective?

• A. Potassium level of 4.0 mEq/L.
• B. Blood glucose level of 180 mg/dL.
• C. Urine output of 50 mL/hour.
• D. Absence of ketones in the urine.

Correct answer: D

Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.
