Nursing Elites

1. A patient with chronic heart failure is prescribed carvedilol. What is the primary purpose of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: C

Rationale: Carvedilol, a beta-blocker, is primarily prescribed in patients with chronic heart failure to decrease heart rate and reduce the workload on the heart. By lowering the heart rate, carvedilol helps the heart function more efficiently and improves symptoms in patients with heart failure.

2. A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Platelet count
• C. Activated partial thromboplastin time (aPTT)
• D. International normalized ratio (INR)

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works by prolonging the clotting time, which is reflected in the aPTT results. Monitoring aPTT helps ensure the patient is within the therapeutic range and not at risk of bleeding or clotting complications. Prothrombin time (PT) (Choice A) primarily measures the extrinsic pathway of coagulation and is used to monitor warfarin therapy, not heparin. Platelet count (Choice B) assesses the number of platelets present in the blood and is not specific to monitoring heparin therapy. International normalized ratio (INR) (Choice D) is used to monitor warfarin therapy, not heparin.

3. A patient with rheumatoid arthritis is prescribed methotrexate. What is an important teaching point for the nurse to provide?

• A. Take folic acid supplements as prescribed.
• B. Avoid alcohol completely.
• C. Expect to see immediate results.
• D. Limit fluid intake to 1 liter per day.

Correct answer: A

Rationale: The correct teaching point for a patient prescribed methotrexate is to take folic acid supplements as prescribed. Methotrexate can lead to a folate deficiency, which is why supplementing with folic acid is essential to reduce the risk of side effects such as mouth sores, nausea, and liver problems.

4. A patient with a diagnosis of deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. Bleeding time
• D. Platelet count

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.

5. A client with heart failure is prescribed furosemide (Lasix). Which instruction should the nurse include in the client's teaching plan?

• A. Take the medication before bedtime.
• B. Report any weight gain of more than 2 pounds in a day.
• C. Increase your intake of high-sodium foods.
• D. Limit your fluid intake to less than 1 liter per day.

Correct answer: B

Rationale: In heart failure, fluid retention is a concern. Furosemide helps manage this by promoting diuresis. Instructing the client to report weight gain exceeding 2 pounds in a day is crucial as it can indicate fluid accumulation, prompting timely intervention to prevent worsening heart failure symptoms and complications.
