1. A healthcare professional is administering a Dopamine infusion at a low dose to a client with severe heart failure. Which of the following findings is an expected effect of this medication?

• A. Lowered heart rate
• B. Increased myocardial contractility
• C. Decreased conduction through the AV node
• D. Vasoconstriction of renal blood vessels

Correct answer: B

Rationale: Dopamine, when administered at a low dose, is expected to increase myocardial contractility by stimulating beta1 receptors. This positive inotropic effect leads to an increase in cardiac output. Therefore, the correct answer is increased myocardial contractility, as it is a desired effect of administering dopamine to a client with severe heart failure.

2. While caring for a client on long-term aspirin therapy, the nurse should monitor the client for which of the following complications?

• A. Hemorrhagic stroke
• B. Thromboembolic stroke
• C. Iron deficiency anemia
• D. Neutropenia

Correct answer: A

Rationale: Corrected Rationale: Long-term aspirin therapy can increase the risk of hemorrhagic stroke due to its antiplatelet effects, which can lead to bleeding complications. Aspirin inhibits platelet function, potentially causing bleeding in the brain and increasing the risk of a hemorrhagic stroke. Choice B, thromboembolic stroke, is incorrect because aspirin therapy is actually used to prevent thromboembolic events by inhibiting platelet aggregation. Choices C and D, iron deficiency anemia and neutropenia, are not directly associated with long-term aspirin therapy.

3. A client is prescribed Lithium. Which of the following laboratory values should be monitored to assess for potential toxicity?

• A. Serum sodium
• B. Serum lithium
• C. Serum potassium
• D. Serum calcium

Correct answer: B

Rationale: When a client is prescribed Lithium, monitoring serum lithium levels is crucial to ensure they remain within the therapeutic range and to assess for potential toxicity. Monitoring serum lithium levels helps prevent adverse effects associated with lithium toxicity, such as nausea, vomiting, diarrhea, tremors, and confusion.

4. Which drug class has been found to decrease mortality if given within 8 hours of an MI due to a decrease in cardiac workload?

• A. Antiplatelets
• B. Beta-adrenergic blockers
• C. ACE inhibitors
• D. Calcium channel blockers

Correct answer: B

Rationale: Beta-adrenergic blockers have been shown to decrease mortality when administered within 8 hours of a myocardial infarction (MI). They do so by reducing cardiac workload, which helps improve outcomes post-MI. These drugs work by blocking the effects of adrenaline on the heart, leading to decreased heart rate, blood pressure, and myocardial oxygen demand, thereby protecting the heart muscle from further damage. This makes them a crucial part of the treatment regimen for acute coronary syndromes like MI.

5. Which of the following drugs has a therapeutic effect that prevents thromboembolic events?

• A. Warfarin
• B. Amlodipine
• C. Nitroglycerin
• D. Clopidogrel

Correct answer: A

Rationale: The correct answer is Warfarin. Warfarin is an anticoagulant medication that helps prevent thromboembolic events by inhibiting the formation of blood clots. It is commonly used to reduce the risk of strokes or heart attacks in patients at risk for thrombosis.
