Nursing Elites

1. 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.

2. A client has a new prescription for Clopidogrel. Which of the following instructions should the nurse include?

• A. Monitor for signs of bleeding.
• B. Avoid taking the medication with food.
• C. Expect to have increased urination.
• D. Take the medication with an antacid.

Correct answer: A

Rationale: Corrected Rationale: Clopidogrel is an antiplatelet medication that increases the risk of bleeding. The client should monitor for any signs of bleeding, such as easy bruising, prolonged bleeding from cuts, blood in urine or stool, and report them promptly to their healthcare provider for further evaluation and management. Choice B is incorrect because Clopidogrel can be taken with or without food. Choice C is incorrect as increased urination is not a common side effect of Clopidogrel. Choice D is incorrect as taking Clopidogrel with an antacid may reduce its effectiveness.

3. When assessing a client taking Lithium Carbonate for Bipolar disorder, which finding should the nurse recognize as a possible indication of toxicity to this medication?

• A. Severe hypertension
• B. Coarse tremors
• C. Constipation
• D. Muscle spasm

Correct answer: B

Rationale: The correct answer is B: Coarse tremors. Coarse tremors are a common sign of Lithium toxicity. Monitoring for tremors is crucial as they can indicate a potentially serious complication that requires immediate intervention. While other options such as severe hypertension, constipation, and muscle spasm may be symptoms of various conditions, they are not typically associated with Lithium toxicity. Severe hypertension is not a common sign of Lithium toxicity; constipation is not a typical symptom of Lithium toxicity either, and muscle spasm is not a direct indicator of Lithium toxicity.

4. A client is taking metformin for type 2 diabetes. Which of the following findings should indicate to the nurse that the medication is effective?

• A. Increased urine output
• B. Decreased fasting blood glucose
• C. Decreased hemoglobin A1C
• D. Decreased polyuria

Correct answer: C

Rationale: A decrease in hemoglobin A1C is a more specific indicator of metformin's effectiveness in controlling blood glucose levels over a longer period compared to fasting blood glucose levels. Hemoglobin A1C reflects average blood sugar levels over the past 2-3 months, providing a more comprehensive view of glycemic control. Increased urine output (choice A) is not a direct indicator of metformin's effectiveness and can be influenced by various factors. Decreased fasting blood glucose (choice B) can fluctuate due to various reasons and may not provide a reliable long-term assessment of metformin's efficacy. Decreased polyuria (choice D) refers to a symptom rather than a direct measure of metformin's effectiveness in managing diabetes.

5. What is the antidote for Heparin?

• A. Atropine
• B. Protamine sulfate
• C. Calcium carbonate
• D. Ferrous sulfate

Correct answer: B

Rationale: Protamine sulfate is the specific antidote used to reverse the effects of Heparin by binding to heparin and neutralizing its anticoagulant properties. It is crucial to administer Protamine sulfate promptly in cases of Heparin overdose or when immediate reversal of Heparin's effects is required to prevent bleeding complications. Atropine is not the antidote for Heparin; it is commonly used for treating bradycardia. Calcium carbonate is used to treat conditions like acid indigestion, heartburn, or calcium deficiency. Ferrous sulfate is a form of iron supplement used to treat or prevent iron deficiency anemia. None of these alternatives are antidotes for Heparin.
