1. What is the most important nursing intervention for a patient with a suspected pulmonary embolism?

• A. Administer anticoagulants
• B. Administer oxygen
• C. Reposition the patient
• D. Monitor oxygen saturation

Correct answer: A

Rationale: The most important nursing intervention for a patient with a suspected pulmonary embolism is to administer anticoagulants. Anticoagulants help prevent further clot formation in the patient's blood vessels, reducing the risk of complications such as worsening of the pulmonary embolism or development of new clots. Administering oxygen (Choice B) may be necessary to support the patient's oxygenation, but anticoagulants take precedence as they target the underlying cause of the pulmonary embolism. Repositioning the patient (Choice C) and monitoring oxygen saturation (Choice D) are important aspects of patient care but are not the primary intervention for a suspected pulmonary embolism.

2. 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.

3. What is the correct method to teach a patient about self-administration of insulin?

• A. Inject into the upper arm
• B. Rotate injection sites
• C. Use a 45-degree angle for injection
• D. Use a 90-degree angle for injection

Correct answer: D

Rationale: The correct method to teach a patient about self-administration of insulin is to use a 90-degree angle for injection. This angle ensures proper subcutaneous administration of insulin, which is essential for effective absorption. Injecting into the upper arm (Choice A) is not recommended for insulin administration. While rotating injection sites (Choice B) is important to prevent lipodystrophy, the angle of injection is crucial for proper insulin delivery. Using a 45-degree angle (Choice C) is more suitable for intramuscular injections, not for subcutaneous insulin injections.

4. A nurse is caring for a client who has deep vein thrombosis of the left lower extremity. Which of the following actions should the nurse take?

• A. Position the client with the affected extremity higher than the heart
• B. Administration of acetaminophen
• C. Massage the affected extremity every 4 hours
• D. Withhold heparin IV infusion

Correct answer: D

Rationale: The correct action for the nurse to take when caring for a client with deep vein thrombosis is to withhold heparin IV infusion. Administering heparin is crucial in managing deep vein thrombosis by preventing further clot formation. Positioning the affected extremity higher than the heart (Choice A) promotes venous return and reduces swelling. Acetaminophen (Choice B) can be given for pain relief. Massaging the affected extremity (Choice C) is contraindicated as it can dislodge a clot, leading to serious complications.

5. A client is receiving heparin therapy. Which of the following laboratory results indicates the client is receiving an effective dose of heparin?

• A. INR 1.5
• B. aPTT 60 seconds
• C. Platelets 150,000/mm³
• D. Potassium 4.0 mEq/L

Correct answer: B

Rationale: An aPTT of 60 seconds indicates the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for a clot to form, and a therapeutic range for heparin therapy is usually 1.5 to 2 times the control value, which is around 60-80 seconds. An INR of 1.5 is not related to heparin therapy, as it is commonly used to monitor warfarin therapy. Platelet count and potassium levels are not direct indicators of the effectiveness of heparin therapy.
