1. A client has been prescribed Aspirin for prevention of cardiovascular disease. Which of the following findings indicates the medication is effective?
- A. The client has a decrease in troponin levels.
- B. The client has a regular heart rhythm.
- C. The client experiences a decrease in episodes of angina.
- D. The client's blood pressure remains stable.
Correct answer: C
Rationale: The correct answer is C. A decrease in episodes of angina indicates that Aspirin is effectively preventing the formation of clots that could lead to cardiovascular events. Angina is chest pain or discomfort caused by reduced blood flow to the heart muscle, usually due to coronary artery disease. Aspirin works by inhibiting platelet aggregation, thereby reducing the risk of clot formation in the arteries. Improvement in angina symptoms suggests that the medication is successfully preventing clot-related complications in the cardiovascular system. Monitoring and recognizing a decrease in angina episodes can be a valuable indicator of the medication's efficacy in preventing cardiovascular events. Choices A, B, and D are incorrect because a decrease in troponin levels, a regular heart rhythm, or stable blood pressure, while important parameters, do not directly reflect the effectiveness of Aspirin in preventing cardiovascular events through antiplatelet action.
2. A client is receiving Enoxaparin for the prevention of deep vein thrombosis. Which of the following actions should the nurse take?
- A. Massage the injection site after administration.
- B. Administer the medication intramuscularly.
- C. Administer the medication into the subcutaneous tissue.
- D. Administer the medication into the deltoid muscle.
Correct answer: C
Rationale: Enoxaparin, a medication used for preventing deep vein thrombosis, should be administered into the subcutaneous tissue, typically in the abdomen. Administering the medication intramuscularly (Choice B) or into the deltoid muscle (Choice D) is incorrect because Enoxaparin is specifically formulated for subcutaneous administration. Massaging the injection site after administration (Choice A) is contraindicated as it may lead to tissue damage and affect the absorption of the medication. Therefore, the correct action is to administer the medication into the subcutaneous tissue as directed.
3. A client has a new prescription for Omeprazole. Which of the following instructions should the nurse include?
- A. Take this medication before meals.
- B. Take this medication with food.
- C. Take this medication at bedtime.
- D. Take this medication with antacids.
Correct answer: A
Rationale: The correct answer is A: 'Take this medication before meals.' Omeprazole is a proton pump inhibitor that should be taken before meals to be most effective in reducing stomach acid production. Taking it before meals allows the medication to inhibit the proton pumps in the stomach when they are most active, leading to better control of acid secretion. Choice B is incorrect because taking Omeprazole with food may reduce its effectiveness as food can interfere with its absorption. Choice C is incorrect as Omeprazole is more effective when taken before meals. Choice D is incorrect as Omeprazole should not be taken with antacids as they can reduce its absorption.
4. A client has a new prescription for Prednisone. Which of the following instructions should be included in the discharge teaching?
- A. Increase your intake of potassium-rich foods.
- B. Avoid consuming grapefruit juice.
- C. Take this medication with food.
- D. Decrease your intake of sodium-rich foods.
Correct answer: A
Rationale: The correct answer is A: 'Increase your intake of potassium-rich foods.' Prednisone can lead to potassium depletion, making it important for clients to increase their intake of potassium-rich foods like bananas, oranges, and spinach to prevent potential complications. Choice B is incorrect because grapefruit juice can interact with certain medications, but it is not a specific concern with Prednisone. Choice C is incorrect as Prednisone can be taken with or without food. Choice D is also incorrect because there is no direct relationship between Prednisone and sodium-rich foods.
5. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:
- A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
- B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
- C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
- D. To lower blood glucose by stimulating the release of insulin
Correct answer: A
Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.
