Extract:
Question 1 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 2 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 3 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.
Question 4 of 5
A nurse is collecting data from a client who has schizophrenia and recently stopped taking chlorpromazine after 8 years. The nurse notes choreiform movements, lip smacking, and spastic facial distortions. The nurse should document these findings as indicating which of the following conditions?
Correct Answer: D
Rationale: The correct answer is D: Tardive dyskinesia. Tardive dyskinesia is a side effect of long-term antipsychotic use, such as chlorpromazine, characterized by involuntary movements like choreiform movements, lip smacking, and spastic facial distortions. These symptoms typically appear after years of treatment and can be irreversible. Akathisia (
A) is restlessness, Dystonia (
B) is muscle contractions, and Pseudoparkinsonism (
C) is tremors and rigidity, none of which match the symptoms described.
Therefore, the correct choice is D.
Question 5 of 5
A nurse is preparing to administer vitamin K 1mg IM to a newborn. Available is vitamin K injection 1 mg/0.5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: The correct answer is A: 0.5 mL.
To determine the mL to administer, we use the formula: Dose required (1 mg) divided by Dose available (1 mg/0.5 mL), which equals 0.5 mL. This calculation ensures the correct dosage is administered. The other choices are incorrect because B (0.1 mL) is too low, C (1.0 mL) is double the correct dose, and D (0.25 mL) is half the required dosage.
Therefore, A (0.5 mL) is the appropriate amount for administering vitamin K 1mg IM to a newborn.
