1. A nurse is caring for a client who has a new prescription for warfarin. Which of the following laboratory tests should the nurse use to monitor the client's therapeutic response to the medication?

Correct answer: A

Rationale: The correct answer is A: INR. The INR (International Normalized Ratio) is the laboratory test used to monitor the therapeutic response of warfarin. It helps ensure that the client's clotting time is within the desired range to prevent complications such as excessive bleeding or clotting. Choice B, aPTT (Activated Partial Thromboplastin Time), is not typically used to monitor warfarin therapy but rather for assessing heparin therapy. Choice C, Platelet count, assesses the number of platelets in the blood and is not specifically used to monitor warfarin therapy. Choice D, Hemoglobin A1C, is a test used to monitor long-term blood sugar control in diabetic patients and is not relevant to monitoring warfarin therapy.

2. Which of the following actions is appropriate when administering a blood transfusion?

Correct answer: A

Rationale: Verifying the patient's identity is a critical step when administering a blood transfusion to ensure that the correct blood product is given to the right patient. This process helps prevent errors and enhances patient safety. Choice B, 'Administer medication,' is incorrect because the focus during a blood transfusion should be on ensuring the correct blood product is administered. Choice C, 'Monitor vital signs,' is also important but comes after verifying the patient's identity. Choice D, 'Start blood transfusion without verification,' is incorrect and unsafe as patient identification verification is essential prior to starting any medical procedure, especially one as important as a blood transfusion.

3. A nurse is assessing a client who has a deep vein thrombosis (DVT). Which of the following findings should the nurse report to the provider?

Correct answer: B

Rationale: Shortness of breath is a critical finding that can indicate a pulmonary embolism, a severe complication of DVT. This symptom suggests a potential life-threatening situation and requires immediate intervention. Calf tenderness, while common in DVT, is not as urgent as shortness of breath. Elevated blood pressure and a respiratory rate of 18/min are important to assess but are not typically as indicative of a serious complication like a pulmonary embolism.

4. What is the best way to assess for fluid overload in a patient with heart failure?

Correct answer: A

Rationale: The correct answer is to 'Check daily weight.' Monitoring daily weight is the most accurate method to assess for fluid overload in patients with heart failure. Weight gain can indicate fluid retention, a common issue in heart failure patients. Checking blood pressure (Choice B) can provide information about hemodynamic status but may not be as specific for fluid overload as monitoring weight. Monitoring heart sounds (Choice C) can provide information about cardiac function but may not directly assess fluid overload. Assessing for jugular vein distention (Choice D) can be a sign of increased central venous pressure but may not always correlate with fluid overload as accurately as daily weight checks.

5. A nurse is caring for a client who has depression and reports taking St. John's wort along with citalopram. The nurse should monitor the client for which of the following conditions as a result of an interaction between these substances?

Correct answer: A

Rationale: The correct answer is A: Serotonin syndrome. When a client takes St. John's wort, a herbal supplement, along with citalopram, a selective serotonin reuptake inhibitor (SSRI), there is a risk of developing serotonin syndrome. Serotonin syndrome is a potentially life-threatening condition characterized by symptoms such as confusion, agitation, fever, sweating, shivering, tremors, muscle rigidity, and in severe cases, seizures and coma. It is crucial for the nurse to monitor the client for these symptoms. Choices B, C, and D are incorrect because tardive dyskinesia is associated with long-term use of antipsychotic medications, pseudo-parkinsonism is a side effect of antipsychotic medications like haloperidol, and acute dystonia is a side effect of antipsychotic medications characterized by sustained muscle contractions.
