1. What is the antidote for Warfarin?
- A. Vitamin D
- B. Vitamin C
- C. Vitamin K
- D. Vitamin B6
Correct answer: C
Rationale: Vitamin K is the antidote for Warfarin toxicity as it helps reverse the anticoagulant effects of Warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin. Vitamin D, Vitamin C, and Vitamin B6 do not have the specific mechanism to counteract the anticoagulant effects of Warfarin, making them incorrect choices.
2. What should you monitor when administering Clopidogrel to a patient?
- A. Signs of thrombotic thrombocytopenic purpura
- B. Bleeding during therapy
- C. CBC with differential and platelet count
- D. All of the above
Correct answer: D
Rationale: When administering Clopidogrel, it is crucial to monitor for signs of thrombotic thrombocytopenic purpura, bleeding during therapy, and changes in CBC with differential and platelet count. Thrombotic thrombocytopenic purpura is a rare but serious condition associated with Clopidogrel use, characterized by microangiopathic hemolytic anemia, thrombocytopenia, neurological symptoms, fever, and renal dysfunction. Monitoring for signs of thrombotic thrombocytopenic purpura is essential to detect this potentially life-threatening condition early. Monitoring for bleeding helps to assess the risk of hemorrhagic events, a known side effect of Clopidogrel. Additionally, regular monitoring of CBC with differential and platelet count is necessary to evaluate the drug's impact on blood cell counts and detect any abnormalities that may require intervention. Therefore, monitoring all these parameters is vital to ensure patient safety and appropriate management during Clopidogrel therapy.
3. A client taking nitroglycerin (Nitrostat) complains of a headache. Which conclusion is most appropriate by the nurse?
- A. A headache indicates a serious allergic reaction to nitroglycerin.
- B. The client will not have a headache if the nitroglycerin is taken with a high-fat meal.
- C. Nitroglycerin does not cause a headache.
- D. The most common side effect of nitroglycerin is a headache.
Correct answer: D
Rationale: Nitroglycerin is known to cause headaches as a common side effect due to its vasodilatory properties. It dilates blood vessels, which can lead to headaches. While a headache can indicate other serious conditions, the most common association with nitroglycerin use is a headache. It is crucial for the nurse to recognize this side effect and provide appropriate education and support to the client.
4. Which of the following medications is a bronchodilator?
- A. Albuterol
- B. Omeprazole
- C. Ondansetron
- D. Senna
Correct answer: A
Rationale: Albuterol is classified as a bronchodilator, which is commonly used to treat conditions like asthma by relaxing the muscles in the airways and increasing airflow to the lungs. Omeprazole is a proton pump inhibitor used to reduce stomach acid production, while ondansetron is an anti-nausea medication, and senna is a laxative.
5. While reviewing a client's medical history, a healthcare professional notes a prescription for Digoxin. Which of the following findings is a manifestation of Digoxin toxicity?
- A. Elevated blood pressure
- B. Bradycardia
- C. Yellow-tinged vision
- D. Ringing in the ears
Correct answer: C
Rationale: Yellow-tinged vision is a visual disturbance associated with Digoxin toxicity, often accompanied by other symptoms like nausea, vomiting, and confusion. Bradycardia is a common therapeutic effect of Digoxin, while elevated blood pressure and ringing in the ears are not typically associated with Digoxin toxicity. Therefore, the correct answer is yellow-tinged vision as a manifestation of Digoxin toxicity.
