1. What is a severe adverse effect of warfarin?

• A. Bleeding
• B. Arrhythmias
• C. Blurred vision
• D. Bradycardia

Correct answer: A

Rationale: A severe adverse effect of warfarin is bleeding. Warfarin is an anticoagulant medication that works by inhibiting blood clotting factors, which can lead to an increased risk of bleeding. Excessive bleeding can occur internally or externally, and it is crucial for individuals taking warfarin to be aware of this potential complication and seek medical attention if they experience any signs of bleeding. Arrhythmias, blurred vision, and bradycardia are not typically associated with warfarin use, making them incorrect choices.

2. When caring for a client prescribed warfarin, which laboratory test should the nurse monitor to evaluate the therapeutic effect of the medication?

• A. aPTT
• B. Platelet count
• C. BUN
• D. PT/INR

Correct answer: D

Rationale: The correct laboratory test to monitor the therapeutic effect of warfarin is the PT/INR. Warfarin affects blood clotting, and the PT/INR levels indicate the effectiveness of the medication in preventing clot formation. Therefore, monitoring PT/INR levels helps ensure that the client is within the therapeutic range and is protected from potential complications related to clotting. Choice A (aPTT) is incorrect because while it measures the clotting time, it is not the preferred test for monitoring warfarin therapy. Choice B (Platelet count) is incorrect as it assesses the number of platelets and not the medication's therapeutic effect. Choice C (BUN) is unrelated to monitoring the effects of warfarin therapy and is primarily used to assess kidney function.

3. When preparing to administer IV Acyclovir for Herpes Zoster, what action should the nurse take?

• A. Infuse the medication over 1 hour.
• B. Monitor the client's blood pressure every 15 minutes during infusion.
• C. Administer a stool softener.
• D. Monitor the client's blood glucose level every 4 hours during infusion.

Correct answer: A

Rationale: The correct action for the nurse is to infuse IV Acyclovir over at least 1 hour to prevent nephrotoxicity. Rapid infusion can lead to adverse effects, so a slow infusion rate is crucial for patient safety. Monitoring blood pressure, administering a stool softener, or monitoring blood glucose levels are not directly related to the administration of IV Acyclovir for Herpes Zoster.

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. A healthcare provider is educating a group of new parents about immunizations. The provider should instruct the parents that the series for which of the following vaccines is completed prior to the first birthday?

• A. Pneumococcal conjugate vaccine
• B. Meningococcal conjugate vaccine
• C. Varicella vaccine
• D. Rotavirus vaccine

Correct answer: D

Rationale: The correct answer is D, Rotavirus vaccine. The series for the Rotavirus vaccine is completed prior to the first birthday as it is only administered to infants less than 8 months of age. This vaccine provides protection against severe diarrhea and vomiting caused by rotavirus infection, which is common in infants and young children. Choices A, B, and C are incorrect because the series for these vaccines extends beyond the first birthday. Pneumococcal conjugate vaccine and Meningococcal conjugate vaccine are typically given in multiple doses up to 2 years of age, while the Varicella vaccine is usually administered between 12 to 15 months of age.
