1. A nurse is caring for a client who has deep-vein thrombosis (DVT) and is receiving heparin therapy. Which of the following laboratory values indicates that the client's heparin therapy is effective?
- A. aPTT 75 seconds.
- B. INR 1.2.
- C. Hemoglobin 10 g/dL.
- D. Fibrinogen level 350 mg/dL.
Correct answer: A
Rationale: An aPTT of 75 seconds indicates that heparin therapy is within the therapeutic range for a client with DVT. The activated partial thromboplastin time (aPTT) is used to monitor heparin therapy's effectiveness. Choice B, INR 1.2, is not the correct answer because INR is used to monitor the effectiveness of warfarin, a different anticoagulant, not heparin. Choice C, Hemoglobin 10 g/dL, is not a measure of heparin therapy effectiveness. Choice D, Fibrinogen level 350 mg/dL, is not a specific indicator of heparin therapy effectiveness for DVT.
2. A client is recovering from an acute myocardial infarction that occurred 3 days ago. Which of the following instructions should the nurse include?
- A. Perform an ECG every 12 hours
- B. Place the client in a supine position while resting
- C. Draw a troponin level every 4 hours
- D. Obtain a cardiac rehabilitation consultation
Correct answer: D
Rationale: After an acute myocardial infarction, it is important to involve the client in cardiac rehabilitation to help them recover and manage their condition effectively. Performing an ECG every 12 hours is not necessary unless there are specific indications for it. Placing the client in a supine position may not be ideal as it can increase venous return, potentially worsening cardiac workload. Drawing troponin levels every 4 hours is excessive and not recommended as troponin levels usually peak within 24-48 hours post-MI and then gradually decline.
3. How should a healthcare provider monitor a patient receiving heparin therapy?
- A. Monitor aPTT
- B. Monitor platelet count
- C. Monitor sodium levels
- D. Monitor calcium levels
Correct answer: A
Rationale: The correct answer is to monitor aPTT (activated partial thromboplastin time) when a patient is receiving heparin therapy. aPTT monitoring is essential for assessing the therapeutic effectiveness of heparin, ensuring the patient is within the desired therapeutic range to prevent both clotting and bleeding. Monitoring platelet count (Choice B) is important for assessing for heparin-induced thrombocytopenia but is not the primary monitoring parameter for heparin therapy. Monitoring sodium levels (Choice C) and calcium levels (Choice D) are not directly related to assessing the therapeutic effectiveness or potential side effects of heparin therapy.
4. What is the initial action a healthcare provider should take for a patient with chest pain?
- A. Administer oxygen
- B. Administer nitroglycerin
- C. Administer morphine
- D. Prepare for surgery
Correct answer: A
Rationale: The correct initial action for a patient with chest pain is to administer oxygen. Chest pain can be caused by insufficient oxygenation, and providing oxygen helps alleviate the pain by increasing oxygen levels in the blood. Administering nitroglycerin or morphine may be appropriate based on the underlying cause of the chest pain, but oxygen should be given first to ensure the patient's oxygen supply is adequate. Surgery is not typically the initial intervention for chest pain.
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?
- A. Serotonin syndrome
- B. Tardive dyskinesia
- C. Pseudo-parkinsonism
- D. Acute dystonia
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.
