Pharmacology for LPN
1. The client is starting therapy with digoxin (Lanoxin). What instruction should the nurse reinforce about the medication?
- A. Take the medication with meals.
- B. Avoid dairy products.
- C. Monitor for yellow or blurred vision.
- D. Increase potassium-rich foods in the diet.
Correct answer: C
Rationale: The correct answer is C: 'Monitor for yellow or blurred vision.' When a client is taking digoxin, it is crucial to monitor for signs of toxicity, such as yellow or blurred vision, as these can indicate an adverse reaction. Reporting these visual disturbances promptly to the healthcare provider is important for further evaluation and management to prevent potential complications. Choices A, B, and D are incorrect because taking digoxin with meals, avoiding dairy products, or increasing potassium-rich foods are not specific instructions related to monitoring for adverse effects of digoxin therapy.
2. A client has a new prescription for heparin. Which of the following laboratory results should be monitored to evaluate the effectiveness of the medication?
- A. Prothrombin time (PT)
- B. International normalized ratio (INR)
- C. Activated partial thromboplastin time (aPTT)
- D. Platelet count
Correct answer: C
Rationale: Activated partial thromboplastin time (aPTT) is the laboratory result that should be monitored to evaluate the effectiveness of heparin. Heparin works by prolonging the aPTT, and monitoring this parameter helps ensure the medication's effectiveness and safety in preventing clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor the effectiveness of warfarin, another anticoagulant. Platelet count is essential to assess platelet function and clotting disorders, but it is not specifically used to monitor heparin therapy.
3. A client has a new prescription for metformin. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Monitor for signs of hyperglycemia.
- C. Increase your fluid intake.
- D. Expect a sweet taste in your mouth.
Correct answer: C
Rationale: The correct instruction for a client starting metformin is to increase fluid intake. Metformin commonly causes gastrointestinal discomfort, and increasing fluid intake can help alleviate this side effect. Instructing the client to take the medication with food (Choice A) rather than on an empty stomach is recommended to reduce gastrointestinal side effects. Monitoring for signs of hyperglycemia (Choice B) is not directly related to metformin but rather to low blood sugar. Expecting a sweet taste in the mouth (Choice D) is not a common side effect of metformin.
4. A client is being taught about the use of an albuterol inhaler. Which of the following instructions should be included?
- A. Use the inhaler every 4 hours around the clock.
- B. Shake the inhaler well before use.
- C. Rinse your mouth with water after each use.
- D. Use the inhaler while lying down.
Correct answer: B
Rationale: Shaking the inhaler well before use is a crucial step in ensuring proper medication delivery. This action helps disperse the medication evenly within the device, optimizing the effectiveness of each dose. It ensures that the client receives the intended amount of medication. The other options are incorrect: Option A suggests a fixed time interval for inhaler use, which may not be suitable for all clients and can lead to overuse. Option C, rinsing the mouth, is more relevant for corticosteroid inhalers to prevent oral thrush. Option D, using the inhaler while lying down, is not recommended as it may lead to improper drug delivery and is not the correct position for inhaler use.
5. The nurse is assisting in the care of a client with a history of chronic obstructive pulmonary disease (COPD) who is on oxygen therapy. Which action should the nurse take to ensure the client's safety?
- A. Set the oxygen flow rate to 4 liters per minute.
- B. Remove oxygen while the client is eating.
- C. Ensure the client wears a nasal cannula instead of a face mask.
- D. Maintain the oxygen flow rate at the lowest level that relieves hypoxia.
Correct answer: D
Rationale: For clients with COPD, too much oxygen can suppress their drive to breathe, leading to hypoventilation. Therefore, the nurse should maintain the oxygen flow rate at the lowest level that relieves hypoxia to prevent complications while ensuring adequate oxygenation. Setting the oxygen flow rate too high (Choice A) can be detrimental for the client with COPD. Removing oxygen while the client is eating (Choice B) can compromise oxygenation, which is essential even during meals. While nasal cannulas are commonly used, the choice of oxygen delivery device depends on the client's needs; there may be situations where a face mask (Choice C) is more appropriate.
