Nursing Elites

1. A patient with atrial fibrillation is prescribed warfarin. Which laboratory test should the nurse monitor to assess the effectiveness of the medication?

• A. Complete blood count (CBC)
• B. Prothrombin time (PT)/INR
• C. Partial thromboplastin time (PTT)
• D. Serum potassium level

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT)/INR. Warfarin affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time (PT) and international normalized ratio (INR) is crucial to assess the effectiveness and safety of warfarin therapy. These tests help determine if the patient is within the desired anticoagulation range to prevent either clotting issues or excessive bleeding.

2. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?

• A. Continue taking warfarin until the day of surgery.
• B. Stop taking warfarin three days before surgery.
• C. Switch to aspirin before surgery.
• D. Stop taking warfarin one week before surgery.

Correct answer: D

Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.

3. A client is being educated about type 2 diabetes. The educator can confirm that the client understands the primary treatment for type 2 diabetes when the client states what?

• A. I read that a pancreas transplant will provide a cure for my diabetes.
• B. I will take my oral antidiabetic agents when my morning blood sugar is high.
• C. I will make sure to follow the weight loss plan designed by the dietitian.
• D. I will make sure I call the diabetes educator when I have questions about my insulin.

Correct answer: C

Rationale: The primary treatment approach for managing type 2 diabetes includes following a weight loss plan. Weight loss can improve insulin sensitivity and glycemic control in individuals with type 2 diabetes. Making dietary changes and maintaining a healthy weight are crucial components of managing this condition.

4. What is the primary goal of care for a client experiencing esophageal varices secondary to liver cirrhosis?

• A. Preventing infection
• B. Controlling bleeding
• C. Reducing portal hypertension
• D. Maintaining nutritional status

Correct answer: B

Rationale: The primary goal of care for a client with esophageal varices secondary to liver cirrhosis is to control bleeding. Esophageal varices are fragile, enlarged veins in the esophagus that can rupture and lead to life-threatening bleeding. Controlling bleeding is crucial to prevent severe complications and ensure the client's safety and well-being. Preventing infection (Choice A) is important but not the primary goal in this case. Reducing portal hypertension (Choice C) is a long-term goal that may help prevent variceal bleeding but is not the immediate priority. Maintaining nutritional status (Choice D) is essential for overall health but is secondary to controlling bleeding in this critical situation.

5. A client is being discharged with a new prescription for enoxaparin (Lovenox). Which instruction should the nurse include?

• A. Administer the injection in your thigh.
• B. Do not expel the air bubble from the syringe before injection.
• C. Massage the injection site after administration.
• D. Alternate the injection site between the arms.

Correct answer: B

Rationale: The correct instruction for a client with a prescription for enoxaparin (Lovenox) is not to expel the air bubble from the syringe before injection. This ensures the full dose is delivered without affecting the medication's efficacy. Expelling the air bubble may lead to a loss of medication, resulting in suboptimal treatment. Therefore, it is crucial for the client to follow this instruction to receive the intended therapeutic effect of enoxaparin.
