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 atenolol. Which of the following instructions should be included?
- A. Take the medication with food.
- B. Monitor heart rate daily.
- C. Avoid eating foods high in potassium.
- D. Take the medication at bedtime.
Correct answer: B
Rationale: The correct answer is to monitor heart rate daily. Atenolol is a beta-blocker that can lead to bradycardia, a condition characterized by a slow heart rate. Monitoring the heart rate daily is essential to detect any abnormal changes promptly, allowing for timely medical intervention if necessary. Choice A is incorrect because atenolol can be taken with or without food. Choice C is irrelevant as atenolol does not interact with potassium-rich foods. Choice D is incorrect as atenolol is usually taken in the morning to help manage blood pressure throughout the day.
3. 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.
4. A client is diagnosed with thrombophlebitis. The nurse should tell the client that which prescription is indicated?
- A. Bed rest, with bathroom privileges only
- B. Bed rest, keeping the affected extremity flat
- C. Bed rest, with elevation of the affected extremity
- D. Bed rest, with the affected extremity in a dependent position
Correct answer: C
Rationale: The correct answer is C: Bed rest, with elevation of the affected extremity. Elevating the affected extremity is crucial in managing thrombophlebitis as it helps reduce swelling and promotes venous return. By elevating the affected extremity, the gravitational force assists in venous blood flow back to the heart, thereby reducing the risk of complications associated with thrombophlebitis. Choices A, B, and D are incorrect because they do not address the need for elevation, which is specifically beneficial in the management of thrombophlebitis.
5. A client is taking levothyroxine for hypothyroidism. Which of the following findings should indicate to the healthcare provider that the client is experiencing levothyroxine toxicity?
- A. Weight loss
- B. Insomnia
- C. Heat intolerance
- D. Dry skin
Correct answer: C
Rationale: Heat intolerance is a hallmark sign of levothyroxine toxicity. It indicates that the client may be receiving an excessive dose of levothyroxine, leading to hyperthyroid symptoms. This can happen when the dosage is too high, causing the body to have an excess of thyroid hormone. Weight loss is a common symptom of hyperthyroidism but alone does not specifically indicate levothyroxine toxicity. Insomnia can be related to hyperthyroidism but is not a specific sign of levothyroxine toxicity. Dry skin is more commonly associated with hypothyroidism rather than levothyroxine toxicity.
