1. Which lab value should be closely monitored for a patient receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor potassium levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.

2. A nurse is planning care for a client who is 1 day postoperative following a total knee arthroplasty. Which of the following interventions should the nurse include?

• A. Keep the affected leg elevated as needed.
• B. Apply ice packs to the affected knee as prescribed.
• C. Encourage the client to ambulate as soon as possible.
• D. Perform range-of-motion exercises as instructed.

Correct answer: C

Rationale: Encouraging the client to ambulate as soon as possible is essential in preventing complications like deep vein thrombosis post knee arthroplasty. While keeping the affected leg elevated and applying ice packs can be beneficial in certain situations, early ambulation takes precedence in this case. Performing range-of-motion exercises hourly may not be necessary and could potentially cause more harm than good if not done correctly or excessively.

3. A nurse is reviewing the laboratory results of a client who has heart failure. Which of the following findings should the nurse report to the provider?

• A. Potassium 4.0 mEq/L
• B. Hemoglobin 12 g/dL
• C. BUN 18 mg/dL
• D. Sodium 137 mEq/L

Correct answer: B

Rationale: The correct answer is B: Hemoglobin 12 g/dL. In a client with heart failure, a decrease in hemoglobin levels can indicate anemia, which can exacerbate heart failure symptoms. Reporting this finding to the provider is crucial for appropriate management. Choice A, Potassium 4.0 mEq/L, is within the normal range (3.5-5.0 mEq/L) and does not typically require immediate reporting. Choice C, BUN 18 mg/dL, and Choice D, Sodium 137 mEq/L, are also within normal ranges and not directly related to heart failure management. Therefore, the hemoglobin level is the most critical finding to report in this scenario.

4. A healthcare provider is reviewing the medical record of a client who has schizophrenia and is taking clozapine. Which finding should the healthcare provider identify as a contraindication to the administration of clozapine?

• A. Heart rate 58/min.
• B. Fasting blood glucose 100 mg/dL.
• C. Hgb 14 g/dL.
• D. WBC count 2,900/mm3.

Correct answer: D

Rationale: The correct answer is D: a low WBC count. Clozapine can suppress bone marrow function, leading to a decreased white blood cell count. This condition, known as agranulocytosis, increases the risk of severe infections. Monitoring WBC counts is essential during clozapine therapy. Choices A, B, and C are within normal ranges and are not contraindications for administering clozapine.

5. A nurse is caring for a client who is receiving packed RBCs. Which of the following actions should the nurse take?

• A. Monitor the client's blood glucose level every hour
• B. Administer the blood using a microdrip set
• C. Assess the client's vital signs every 2 hours
• D. Infuse the blood within 4 hours

Correct answer: D

Rationale: The correct answer is to infuse the blood within 4 hours. This is crucial to prevent bacterial contamination and hemolysis during blood transfusions. Monitoring the client's blood glucose level every hour (Choice A) is not directly related to packed RBC transfusions. Administering the blood using a microdrip set (Choice B) may be appropriate for specific medications but is not a requirement for packed RBC transfusions. Assessing the client's vital signs every 2 hours (Choice C) is important for monitoring the client's overall condition but is not as time-sensitive as ensuring the timely infusion of packed RBCs.
