1. A client with known coronary artery disease (CAD) begins to experience chest pain while getting out of bed. What action should the nurse take?
- A. Obtain a prescription for pain medication.
- B. Have the client stop and lie back down in bed.
- C. Report the complaint to the healthcare provider.
- D. Instruct the client to continue getting out of bed and into a chair.
Correct answer: B
Rationale: When a client with CAD experiences chest pain, it indicates myocardial ischemia. The nurse should have the client stop the activity and lie back down in bed to reduce the heart's oxygen demand, decrease myocardial workload, and prevent further ischemia. This action helps in improving blood flow to the heart and can potentially alleviate the chest pain. Option A is incorrect as pain medication should not be the initial action for chest pain in CAD. Option C is incorrect because the nurse should first intervene directly to address the chest pain. Option D is incorrect as continuing the activity can worsen the myocardial ischemia and chest pain.
2. A client has a new prescription for propranolol. Which of the following instructions should be included?
- A. Take the medication with food.
- B. Monitor heart rate daily.
- C. Increase intake of potassium-rich foods.
- D. Avoid consuming dairy products.
Correct answer: B
Rationale: The correct answer is to monitor heart rate daily. Propranolol is a beta-blocker that can lower heart rate and blood pressure, so it is essential to monitor heart rate regularly to detect any signs of bradycardia, a potential side effect of the medication. Choice A is incorrect because propranolol can be taken with or without food. Choice C is incorrect as increasing potassium-rich foods is not specifically required with propranolol. Choice D is also incorrect as there is no need to avoid consuming dairy products with propranolol.
3. The healthcare provider is monitoring a client with chronic stable angina. Which symptom would indicate that the client's condition is worsening?
- A. Increased shortness of breath with exertion
- B. Improved tolerance to activity
- C. Decreased frequency of chest pain
- D. Stable blood pressure readings
Correct answer: A
Rationale: Increased shortness of breath with exertion is a concerning symptom in a client with chronic stable angina as it may indicate inadequate oxygen supply to the heart muscle, suggesting a worsening condition. This could be a sign of reduced blood flow to the heart, leading to increased work for the heart during exertion, resulting in increased shortness of breath. Choice B, improved tolerance to activity, is incorrect as it would indicate a positive response to treatment. Choice C, decreased frequency of chest pain, is incorrect as it would also suggest an improvement in the client's condition. Choice D, stable blood pressure readings, are not indicative of a worsening condition in chronic stable angina.
4. The client with atrial fibrillation is receiving warfarin (Coumadin). Which laboratory test should be monitored to determine the effectiveness of the therapy?
- A. Prothrombin time (PT) and international normalized ratio (INR)
- B. Activated partial thromboplastin time (aPTT)
- C. Complete blood count (CBC)
- D. Fibrinogen level
Correct answer: A
Rationale: Monitoring Prothrombin time (PT) and international normalized ratio (INR) is crucial when a client is on warfarin therapy. These tests assess the clotting ability of the blood and help determine the appropriate dosage of warfarin to prevent complications such as bleeding or clotting events. PT and INR values within the therapeutic range indicate the effectiveness of warfarin in managing atrial fibrillation. Choice B, activated partial thromboplastin time (aPTT), is not typically used to monitor warfarin therapy; it is more commonly used to assess the effectiveness of heparin therapy. Choice C, complete blood count (CBC), does not directly assess the anticoagulant effect of warfarin. Choice D, fibrinogen level, is not a primary test for monitoring warfarin therapy; it is more relevant in assessing conditions like disseminated intravascular coagulation.
5. The LPN/LVN is assisting in caring for a client in the telemetry unit who is receiving an intravenous infusion of 1000 mL of 5% dextrose with 40 mEq of potassium chloride. Which occurrence observed on the cardiac monitor indicates the presence of hyperkalemia?
- A. Tall, peaked T waves
- B. ST segment depressions
- C. Shortened P-R intervals
- D. Shortening of the QRS complex
Correct answer: A
Rationale: In hyperkalemia, tall, peaked T waves are a distinct ECG finding. These T waves can be seen as a result of increased serum potassium levels, affecting the repolarization phase of the cardiac action potential. It is crucial for healthcare providers to recognize this ECG change promptly as hyperkalemia can lead to serious cardiac arrhythmias and complications. ST segment depressions, shortened P-R intervals, and shortening of the QRS complex are not typically associated with hyperkalemia. ST segment depressions are more indicative of myocardial ischemia or infarction. Shortened P-R intervals may be seen in conditions like Wolff-Parkinson-White syndrome. Shortening of the QRS complex is associated with conditions affecting the conduction system of the heart, such as bundle branch blocks.
