1. When educating a client about the use of risedronate to treat osteoporosis, which instruction should be included?
- A. Drink a full glass of water with each dose.
- B. Take the medication on an empty stomach.
- C. Remain upright for 30 minutes after taking the medication.
- D. Avoid lying down for at least 1 hour after taking the medication.
Correct answer: C
Rationale: The correct instruction for a client taking risedronate to treat osteoporosis is to remain upright for 30 minutes after taking the medication. This is important to prevent esophageal irritation, as risedronate can cause irritation if it remains in contact with the esophagus. By staying upright, the medication is more likely to reach the stomach quickly and reduce the risk of irritation to the esophagus. Choices A, B, and D are incorrect. Drinking a full glass of water is recommended, not milk, to help with swallowing the medication. Risedronate should be taken on an empty stomach, not with meals, to ensure proper absorption. Additionally, avoiding lying down for at least 1 hour after taking the medication helps prevent esophageal irritation.
2. A client has a new prescription for amlodipine. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Monitor blood pressure daily.
- C. Increase intake of potassium-rich foods.
- D. Avoid consuming grapefruit juice.
Correct answer: B
Rationale: The correct answer is B: 'Monitor blood pressure daily.' When a client is prescribed amlodipine, it is essential to monitor their blood pressure regularly. Amlodipine is known to cause hypotension, so monitoring blood pressure helps ensure it stays within the desired range to prevent complications associated with low blood pressure. Choice A is incorrect because amlodipine can be taken with or without food. Choice C is incorrect as increasing potassium intake is not a specific instruction related to amlodipine. Choice D is incorrect as grapefruit juice interactions are not typically a concern with amlodipine.
3. A client diagnosed with hypertension is prescribed atenolol (Tenormin). The nurse should monitor the client for which common side effect of this medication?
- A. Tachycardia
- B. Dry mouth
- C. Hypotension
- D. Increased appetite
Correct answer: C
Rationale: Atenolol is a beta-blocker that works by lowering blood pressure. A common side effect of atenolol is hypotension, where blood pressure drops too low. Therefore, the nurse should monitor the client for signs and symptoms of hypotension to prevent any complications. Choices A, B, and D are incorrect because tachycardia (fast heart rate), dry mouth, and increased appetite are not common side effects of atenolol. Hypotension is the expected side effect due to the medication's mechanism of action.
4. The nurse is caring for a client diagnosed with deep vein thrombosis (DVT). Which intervention should the nurse include in the client's plan of care to prevent the complication of pulmonary embolism?
- A. Encourage ambulation as tolerated.
- B. Administer anticoagulants as prescribed.
- C. Apply cold compresses to the affected area.
- D. Encourage the use of incentive spirometry.
Correct answer: B
Rationale: Administering anticoagulants as prescribed is crucial in preventing the complication of pulmonary embolism in clients with deep vein thrombosis. Anticoagulants help prevent the formation of new clots and the enlargement of existing ones, thereby reducing the risk of a pulmonary embolism. Encouraging ambulation as tolerated is beneficial for preventing complications related to immobility, but it is not the primary intervention to prevent pulmonary embolism in this case. Applying cold compresses to the affected area may help with pain and swelling but does not address the prevention of pulmonary embolism. Encouraging the use of incentive spirometry is more relevant in preventing respiratory complications such as atelectasis, not specifically pulmonary embolism.
5. 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.
