Extract:
Question 1 of 5
A nurse is reinforcing teaching with a client who has a prescription for lithium carbonate to treat bipolar disorder. Which of the following instructions should the nurse include?
Correct Answer: B
Rationale: The correct answer is B: Wait up to 3 weeks to see the full effects of the medication. This is because lithium carbonate, commonly used to treat bipolar disorder, takes time to reach therapeutic levels in the blood and for the client to experience the full benefits of the medication. It is important for the nurse to educate the client about this delayed onset of action to manage expectations and encourage adherence to the treatment plan.
A: Taking the medication on an empty stomach is not necessary for lithium carbonate.
C: Following a low-sodium diet is important to monitor for potential side effects, but it is not the most crucial instruction to include.
D: Limiting fluid intake to 800 ounces per day is excessive and could lead to dehydration, so this instruction is incorrect.
E, F, G: No additional options provided.
Question 2 of 5
A nurse is reinforcing teaching with a client who takes diazepam. Which of the following information should the nurse include?
Correct Answer: A
Rationale: The correct answer is A: Diazepam can cause drowsiness. Diazepam is a benzodiazepine used to treat anxiety and seizures. It acts on the central nervous system, which can lead to drowsiness as a common side effect. The nurse should include this information to educate the client about the potential effects of the medication.
Choice B is incorrect because even a single dose of diazepam can cause side effects, especially drowsiness.
Choice C is incorrect as grapefruit juice does not inactivate diazepam but can interact with other medications.
Choice D is incorrect as tyramine interactions are not relevant to diazepam.
Question 3 of 5
A nurse is caring for a client who has chlamydia and a new prescription for azithromycin. Which of the following information should the nurse include when reinforcing teaching about this medication?
Correct Answer: A
Rationale: The correct answer is A: Notify your provider if you experience a sore throat or fever while taking this medication. This is important because azithromycin can cause serious side effects like an allergic reaction leading to a sore throat or fever. It is crucial to inform the healthcare provider immediately if these symptoms occur to prevent any severe complications.
Choice B is incorrect because dark yellow or orange urine is not an expected adverse effect of azithromycin.
Choice C is incorrect as taking azithromycin with antacids can actually decrease its effectiveness.
Choice D is also incorrect as bleeding gums are not a common side effect of azithromycin.
Choices E, F, and G are not provided in the question.
Question 4 of 5
A nurse is assisting with the preparation of an educational program about the use of oral contraceptives. The nurse should include that which of the following herbal supplements reduces the effectiveness of oral contraceptives?
Correct Answer: B
Rationale: The correct answer is B: St. John's wort. St. John's wort is known to induce drug-metabolizing enzymes, potentially reducing the effectiveness of oral contraceptives. It can decrease the blood levels of estrogen and progesterone, making the contraceptives less effective. Ginger root (
A), Gingko biloba (
C), and Glucosamine (
D) do not have known interactions with oral contraceptives. St. John's wort is the only choice that directly impacts the effectiveness of oral contraceptives.
Question 5 of 5
A nurse is reinforcing teaching with a client who has a prescription for oral suspension phenytoin. Which of the following information should the nurse include in the teaching?
Correct Answer: C
Rationale: The correct answer is C: Shake the suspension vigorously prior to pouring the medication. This is important because oral suspensions often settle, and shaking ensures even distribution of the medication for accurate dosing. Option A is incorrect because red-brown urine is not a common side effect of phenytoin. Option B is incorrect as antacids can interfere with phenytoin absorption. Option D is incorrect as an annual flu vaccine is not directly related to phenytoin therapy. Options E, F, and G are not applicable in this scenario.
