1. A client prescribed Warfarin is receiving discharge instructions from a nurse. Which of the following herbal supplements should the nurse instruct the client to avoid?
- A. St. John's wort
- B. Echinacea
- C. Garlic
- D. Ginseng
Correct answer: A
Rationale: St. John's wort can reduce the effectiveness of Warfarin by interacting with its metabolism pathways, potentially leading to decreased anticoagulant effects. Therefore, clients on Warfarin therapy should avoid St. John's wort. While echinacea, garlic, and ginseng are also herbal supplements that can interact with Warfarin, St. John's wort is particularly known for its significant impact on Warfarin metabolism. Echinacea may increase the risk of bleeding when taken with Warfarin, garlic may potentiate the anticoagulant effects of Warfarin, and ginseng may also increase the risk of bleeding. However, St. John's wort is the most crucial to avoid due to its significant impact on Warfarin metabolism.
2. Which medication is contraindicated with Nitroglycerin?
- A. Hydrochloroquine
- B. Methylprednisolone
- C. Phenazopyridine
- D. Erectile dysfunction drugs
Correct answer: D
Rationale: The correct answer is D: Erectile dysfunction drugs. Erectile dysfunction drugs are contraindicated with Nitroglycerin because they can potentiate the hypotensive effects of Nitroglycerin, leading to severe hypotension. Choices A, B, and C are incorrect because they are not known to have significant interactions with Nitroglycerin.
3. A client in a long-term care facility has Hypothyroidism and a new prescription for Levothyroxine. Which of the following dosage schedules should the nurse expect for this client?
- A. The client will start at a high dose, and the dose will be tapered as needed.
- B. The client will remain on the initial dosage during the course of treatment.
- C. The client's dosage will be adjusted daily based on blood levels.
- D. The client will start on a low dose, which will be gradually increased.
Correct answer: D
Rationale: The nurse should expect that levothyroxine will be started at a low dose and gradually increased over several weeks. This cautious approach is crucial, especially in older adult clients, to prevent toxicity and ensure optimal therapeutic outcomes for managing hypothyroidism. Choice A is incorrect because starting at a high dose and tapering as needed is not the standard approach for levothyroxine. Choice B is incorrect because the initial dosage is typically adjusted to reach the optimal therapeutic dose. Choice C is incorrect as adjusting the dosage daily based on blood levels is not necessary for levothyroxine, as it has a long half-life and requires time to reach a steady state.
4. A client is withdrawing from alcohol and has a new prescription for Propranolol. Which of the following information should be included in the teaching?
- A. Increases the risk for seizure activity.
- B. Provides a form of aversion therapy.
- C. Decreases cravings.
- D. Results in mild hypertension.
Correct answer: C
Rationale: The correct answer is C: 'Decreases cravings.' Propranolol is commonly used as an adjunct medication during alcohol withdrawal to help reduce cravings for alcohol. It does not increase the risk for seizure activity, provide aversion therapy, or result in mild hypertension. By decreasing cravings, Propranolol can support the client in managing alcohol withdrawal symptoms and promoting abstinence. Therefore, it is important to educate the client on how Propranolol can help them cope with alcohol cravings effectively.
5. A client has anemia and a new prescription for ferrous sulfate liquid. Which of the following instructions should the nurse provide?
- A. Take the medication on an empty stomach to decrease gastrointestinal irritation.
- B. Take the medication with orange juice to enhance absorption.
- C. Take the medication with milk.
- D. Rinse the mouth before taking the iron.
Correct answer: B
Rationale: Taking ferrous sulfate with orange juice can help increase the absorption of iron. Orange juice contains vitamin C, which aids in the absorption of iron from the medication. This combination can enhance the effectiveness of the iron supplement for a client with anemia. Option A is incorrect because taking iron on an empty stomach can cause gastrointestinal upset. Option C is incorrect because calcium in milk can inhibit iron absorption. Option D is irrelevant to enhancing iron absorption.
