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 Warfarin. Which of the following statements by the client indicates a need for further teaching?

• A. I will avoid eating large amounts of green leafy vegetables.
• B. I will take my medication at the same time every day.
• C. I will increase my intake of foods high in potassium.
• D. I will report any signs of bleeding to my provider.

Correct answer: C

Rationale: The correct answer is C because Warfarin interacts with vitamin K, not potassium. Therefore, the client needs to be cautious with foods high in vitamin K, such as green leafy vegetables, rather than foods high in potassium. Choices A, B, and D are correct statements regarding Warfarin therapy and do not indicate a need for further teaching.

3. Which drug is the antidote for Alprazolam?

• A. Physostigmine
• B. Protamine sulfate
• C. Flumazenil
• D. Acetylcysteine

Correct answer: C

Rationale: Flumazenil is the specific antidote used to reverse the effects of Alprazolam. Alprazolam is a benzodiazepine, and Flumazenil is a benzodiazepine receptor antagonist that works by competitively inhibiting the actions of benzodiazepines at the receptor site, effectively reversing their sedative and other effects. Physostigmine is not used as an antidote for benzodiazepine overdose and can have significant side effects. Protamine sulfate is used to reverse the effects of heparin, not benzodiazepines like Alprazolam. Acetylcysteine is used as an antidote for acetaminophen overdose, not benzodiazepines like Alprazolam.

4. A healthcare provider is reviewing the medical history of a client who is scheduled for surgery and takes Warfarin daily. Which of the following laboratory results should the healthcare provider monitor?

• A. Potassium level
• B. INR
• C. BUN
• D. Platelet count

Correct answer: B

Rationale: The INR (International Normalized Ratio) is the most important lab value to monitor in a client taking warfarin. Warfarin is an anticoagulant, and the INR reflects the effectiveness of anticoagulation therapy. Monitoring the INR helps ensure the client is within the therapeutic range to prevent both clotting and bleeding complications.

5. A healthcare professional is educating a client who is starting therapy with topotecan. Which of the following findings should the professional instruct the client to report?

• A. Hair loss
• B. Fatigue
• C. Sore throat
• D. Red urine

Correct answer: C

Rationale: The correct answer is C: 'Sore throat.' Clients starting therapy with topotecan should be instructed to report a sore throat because it can indicate an infection due to the immunosuppressive effects of the medication. Infections can be serious in clients undergoing chemotherapy, so early detection and treatment are crucial to prevent complications. Choices A, B, and D are incorrect because while they are potential side effects of topotecan, they are usually not as immediately concerning as a sore throat, which could signal a serious infection requiring prompt attention.
