1. What is the antidote for Warfarin?
- A. Naloxone
- B. Vitamin K
- C. Glucagon
- D. Vitamin B
Correct answer: B
Rationale: The correct antidote for Warfarin is Vitamin K. Warfarin works by inhibiting vitamin K-dependent clotting factors. Administering Vitamin K helps reverse its effects by replenishing these factors. Choices A, C, and D are incorrect. Naloxone is used to reverse opioid overdose, Glucagon is used to treat severe low blood sugar, and Vitamin B is not the antidote for Warfarin.
2. A client is starting therapy with Atenolol. Which of the following adverse effects should the nurse instruct the client to monitor?
- A. Tachycardia
- B. Hypoglycemia
- C. Bradycardia
- D. Hypertension
Correct answer: C
Rationale: Atenolol is a beta-blocker that can cause bradycardia as an adverse effect due to its mechanism of action in slowing down the heart rate. The nurse should instruct the client to monitor their pulse regularly and report any significant decreases to prevent complications related to bradycardia.
3. A client has a new prescription for Prednisone. Which of the following instructions should be included in the discharge teaching?
- A. Increase your intake of potassium-rich foods.
- B. Avoid consuming grapefruit juice.
- C. Take this medication with food.
- D. Decrease your intake of sodium-rich foods.
Correct answer: A
Rationale: The correct answer is A: 'Increase your intake of potassium-rich foods.' Prednisone can lead to potassium depletion, making it important for clients to increase their intake of potassium-rich foods like bananas, oranges, and spinach to prevent potential complications. Choice B is incorrect because grapefruit juice can interact with certain medications, but it is not a specific concern with Prednisone. Choice C is incorrect as Prednisone can be taken with or without food. Choice D is also incorrect because there is no direct relationship between Prednisone and sodium-rich foods.
4. A client has a new prescription for Phenytoin. Which of the following instructions should the nurse include?
- A. Brush and floss your teeth regularly.
- B. Avoid drinking grapefruit juice.
- C. Take this medication with food.
- D. Increase your intake of calcium-rich foods.
Correct answer: A
Rationale: The correct answer is to instruct the client to brush and floss their teeth regularly. Phenytoin can lead to gingival hyperplasia, making oral hygiene crucial to prevent complications. Encouraging good oral care practices helps reduce the risk of adverse effects on the gums and teeth. Avoiding grapefruit juice is not specifically related to Phenytoin. While some medications require intake with food, Phenytoin is usually taken on an empty stomach for better absorption. Increasing calcium-rich foods is not directly associated with Phenytoin therapy.
5. A client receives a new prescription for NRTIs for HIV treatment. Which statement should the nurse include during teaching about these medications?
- 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: NRTIs inhibit the enzyme reverse transcriptase, essential for HIV replication. By preventing this process, viral replication is hindered, ultimately reducing the viral load in the body. Option A correctly explains the mechanism of action of NRTIs in treating HIV infection. Choices B, C, and D describe mechanisms of action that do not align with how NRTIs work in HIV treatment. B is incorrect because NRTIs do not target protein synthesis within the HIV cell. C is incorrect as NRTIs do not affect the cell wall of the HIV virus. D is incorrect because NRTIs do not block HIV entry into cells.
