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. A client has a new prescription for combination oral NRTIs for the treatment of HIV. Which of the following statements should the nurse include in discharge teaching?
- A. These medications work by inhibiting enzymes to prevent HIV replication.
- B. These medications work by preventing protein synthesis within the HIV cell.
- C. These medications work by weakening the cell wall of the HIV virus.
- D. These medications work by blocking HIV entry into cells.
Correct answer: A
Rationale: The correct answer is A. NRTI antiretroviral medications inhibit the enzyme reverse transcriptase, which is essential for HIV replication. By blocking this enzyme, the medications prevent the virus from replicating and spreading. This mechanism of action helps to control the progression of HIV infection in the body. Choices B, C, and D are incorrect because NRTIs do not work by preventing protein synthesis, weakening the cell wall of the virus, or blocking HIV entry into cells. These mechanisms are associated with different classes of antiretroviral medications used in HIV treatment.
3. A client is taking Amiodarone to treat Atrial Fibrillation. Which of the following findings is a manifestation of Amiodarone toxicity?
- A. Light yellow urine
- B. Report of tinnitus
- C. Productive cough
- D. Blue-gray skin discoloration
Correct answer: D
Rationale: Blue-gray skin discoloration is a common sign of Amiodarone toxicity, known as blue-gray discoloration, which can affect areas like the face, neck, or hands. It is important to monitor for this side effect, as it can be a visible indicator of potential toxicity. Choices A, B, and C are incorrect. Light yellow urine is not typically associated with Amiodarone toxicity. Tinnitus is not a common manifestation of Amiodarone toxicity. A productive cough is not a recognized symptom of Amiodarone toxicity.
4. A client has a new prescription for Folic Acid. Which of the following client statements indicates an understanding of the teaching?
- A. I will take this medication with food.
- B. I need to monitor for skin rash while taking this medication.
- C. I need to increase my intake of green, leafy vegetables.
- D. I will stop taking this medication if I feel nauseous.
Correct answer: C
Rationale: The correct answer is C. Folic acid is naturally found in green, leafy vegetables such as spinach and broccoli. Increasing the intake of these vegetables can supplement the prescribed folic acid and help maintain adequate levels in the body. It is essential to understand that dietary sources of folic acid can complement the medication and support overall health. Choices A, B, and D are incorrect because taking folic acid with food, monitoring for skin rash, or stopping the medication if feeling nauseous do not directly relate to enhancing the therapeutic effects of folic acid through dietary intake.
5. A client is starting a new prescription for ferrous sulfate. Which of the following instructions should the nurse include?
- A. Take the medication with meals.
- B. Take the medication on an empty stomach.
- C. Take the medication with orange juice to enhance absorption.
- D. Take the medication with a full glass of milk.
Correct answer: C
Rationale: The correct answer is C: 'Take the medication with orange juice to enhance absorption.' Taking ferrous sulfate with orange juice helps enhance the absorption of iron due to the ascorbic acid present in the orange juice, which aids in iron absorption. This combination can help improve the effectiveness of the medication. Choice A, taking the medication with meals, may reduce gastrointestinal side effects but does not specifically enhance absorption. Choice B, taking the medication on an empty stomach, may lead to better absorption but can also increase the risk of gastrointestinal side effects. Choice D, taking the medication with a full glass of milk, is incorrect because calcium in milk can inhibit the absorption of iron.
