Pharmacology for LPN

Correct Answer: B

Rationale: An Electrocardiogram (ECG) is the primary diagnostic tool used to confirm a myocardial infarction. An ECG provides immediate information on cardiac function and can show characteristic changes indicative of a myocardial infarction, such as ST-segment elevation or depression. An echocardiogram (Choice A) is useful for assessing heart structure and function but is not typically used as the primary test for confirming an acute myocardial infarction. Chest X-ray (Choice C) may show certain changes in heart size or pulmonary congestion but is not the primary diagnostic test for MI. A Complete Blood Count (CBC) (Choice D) provides information about the cellular components of blood and is not specific to confirming a myocardial infarction.

Correct Answer: B

Rationale: In the context of an acute myocardial infarction (MI), morphine is administered to relieve pain and reduce myocardial oxygen demand. By alleviating pain and anxiety, morphine helps reduce oxygen demand on the heart, which is beneficial in the setting of an MI. Aspirin, commonly used for its antiplatelet effects, helps inhibit platelet aggregation and is crucial in the management of MI to prevent further clot formation. Atropine is a medication used to treat symptomatic bradycardia by increasing heart rate, not commonly indicated in the management of acute MI. Lidocaine is used for ventricular dysrhythmias and is not typically given to reduce myocardial oxygen demand in an acute MI scenario.

Correct Answer: B

Rationale: Grilled salmon is the correct choice for a client with coronary artery disease on a low-fat, low-cholesterol diet because it is low in saturated fat and high in omega-3 fatty acids, which are beneficial for heart health. Whole milk, fried chicken, and bacon and eggs are higher in saturated fats and cholesterol, making them less suitable choices for this client. Whole milk is high in saturated fat, while fried chicken and bacon and eggs are sources of both saturated fat and cholesterol, which can negatively impact heart health in clients with coronary artery disease.

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.

Correct Answer: A

Rationale: The correct instruction to reinforce is to 'Report any chest pain or discomfort to your health care provider.' This is crucial because chest pain post-angioplasty can indicate complications that need immediate attention. Choice A is incorrect because returning to work immediately may not be advisable after angioplasty, as the client needs time to recover. Choice B is incorrect because avoiding all physical activity for 2 weeks may not be necessary; instead, gradual resumption of activities is usually recommended. Choice D is incorrect because aspirin should be taken as prescribed by the healthcare provider, not just when chest pain occurs.
