LPN Pharmacology Assessment A
1. The healthcare professional is assisting in the care of a client diagnosed with deep vein thrombosis (DVT). Which instruction should be reinforced to prevent complications?
- A. Elevate the affected leg using pillows.
- B. Perform leg exercises while sitting.
- C. Wear snug compression stockings.
- D. Avoid applying ice packs to injuries.
Correct answer: A
Rationale: Elevating the affected leg using pillows is crucial in managing deep vein thrombosis (DVT) as it helps reduce swelling and promote venous return, thereby decreasing the risk of complications such as pulmonary embolism. This position aids in improving blood circulation and preventing blood clots from forming or worsening in the affected leg. Performing leg exercises while sitting might increase the risk of dislodging a blood clot. While snug compression stockings are beneficial, the primary focus should be on elevation. Avoiding ice packs on injuries is unrelated to DVT management.
2. The nurse is informed during shift report that a client is experiencing occasional ventricular dysrhythmias. The nurse reviews the client's laboratory results, recalling that which electrolyte imbalance could be responsible for this development?
- A. Hypokalemia
- B. Hypernatremia
- C. Hypochloremia
- D. Hypercalcemia
Correct answer: A
Rationale: Hypokalemia, which is low potassium levels, can disrupt the normal electrical activity of the heart and lead to ventricular dysrhythmias. Potassium plays a crucial role in maintaining the heart's rhythm, and a deficiency can result in dangerous heart rhythm abnormalities. Hypernatremia (Choice B), which is high sodium levels, does not directly impact heart rhythm. Hypochloremia (Choice C), which is low chloride levels, is not typically associated with ventricular dysrhythmias. Hypercalcemia (Choice D), which is high calcium levels, is not a common cause of ventricular dysrhythmias.
3. The client with chronic stable angina is prescribed a beta blocker. The nurse is reinforcing instructions. What instruction should the nurse include?
- A. Take the medication with a meal.
- B. Report a pulse rate below 60 beats per minute.
- C. Discontinue the medication if dizziness occurs.
- D. Avoid drinking grapefruit juice.
Correct answer: B
Rationale: The correct instruction for the nurse to include is to advise the client to report a pulse rate below 60 beats per minute. Beta blockers are known to lower heart rate, and a pulse rate below 60 beats per minute may indicate bradycardia, a condition that requires medical attention. Option A, 'Take the medication with a meal,' is incorrect because beta blockers don't necessarily need to be taken with food. Option C, 'Discontinue the medication if dizziness occurs,' is incorrect because abrupt cessation of beta blockers can lead to rebound hypertension and other adverse effects. Option D, 'Avoid drinking grapefruit juice,' is unrelated to beta blockers' mechanism of action or side effects.
4. In monitoring the effectiveness of warfarin therapy for a client with a history of atrial fibrillation, which laboratory value should the nurse monitor?
- A. Activated partial thromboplastin time (aPTT)
- B. Prothrombin time (PT) and international normalized ratio (INR)
- C. Platelet count
- D. Erythrocyte sedimentation rate (ESR)
Correct answer: B
Rationale: Prothrombin time (PT) and international normalized ratio (INR) are crucial laboratory values to monitor the effectiveness of warfarin therapy in clients with atrial fibrillation. These values help ensure that the client is within the therapeutic range and that the anticoagulant effect of warfarin is appropriate. Monitoring aPTT, platelet count, or ESR is not directly related to assessing the effectiveness of warfarin therapy in these cases.
5. The healthcare provider is monitoring a client following cardioversion. Which observation should be of the highest priority to the healthcare provider?
- A. Blood pressure
- B. Status of airway
- C. Oxygen flow rate
- D. Level of consciousness
Correct answer: B
Rationale: The status of the airway is the highest priority following cardioversion as it ensures proper oxygenation and helps prevent complications such as airway obstruction and respiratory distress. Maintaining a patent airway is crucial for the client's respiratory function and overall well-being immediately after cardioversion. Monitoring the airway ensures that the client can breathe effectively and minimizes the risk of hypoxia and other serious respiratory issues. While blood pressure, oxygen flow rate, and level of consciousness are also important parameters to monitor, they are secondary to ensuring a clear and patent airway for adequate oxygenation.
