Which of the following medications interacts with carbamazepine?
- A. Nicotine transdermal system
- B. Diphenhydramine
- C. Estrogen-progestin combination (Non-hormonal forms of contraception)
- D. Beclomethasone
Correct Answer: C
Rationale: The correct answer is C: Estrogen-progestin combination (Non-hormonal forms of contraception). Carbamazepine induces the metabolism of estrogen-based contraceptives, leading to decreased efficacy and potential contraceptive failure. This interaction can result in unintended pregnancies. Choices A, B, and D do not have significant interactions with carbamazepine.

Which of the following findings should indicate to the nurse that the ondansetron has been effective?
- A. Client reports a decrease in pain
- B. Client reports a decrease in nausea
- C. Client reports a decrease in coughing
- D. Client reports a decrease in diarrhea
Correct Answer: B
Rationale: The correct answer is B: Client reports a decrease in nausea. Ondansetron is commonly prescribed to treat nausea and vomiting. A decrease in nausea indicates the medication's effectiveness in managing this specific symptom. Choices A, C, and D are incorrect because ondansetron does not directly target pain, coughing, or diarrhea. It is important for the nurse to focus on the primary purpose of the medication and assess the related symptoms to determine its effectiveness.
A nurse is preparing to administer medication to a client who has gout. The nurse discovers that an error was made during the previous shift and the client received atenolol instead of allopurinol.Which of the following actions should the nurse take first when discovering a medication error in which atenolol was given instead of allopurinol to a client with gout?
- A. Obtain the client's blood pressure
- B. Contact the client's provider
- C. Inform the charge nurse
- D. Complete an incident report
Correct Answer: A
Rationale: The correct action for the nurse to take first in this situation is to obtain the client's blood pressure (Choice A). This is important because atenolol is a beta-blocker that can lower blood pressure, and giving it to a client with gout instead of allopurinol can potentially result in adverse effects or exacerbate the underlying condition. By obtaining the client's blood pressure, the nurse can assess if there have been any significant changes since the administration of the incorrect medication. This immediate assessment allows the nurse to monitor for any potential adverse effects and take appropriate action if necessary. Contacting the client's provider (Choice B) would be important, but assessing the immediate impact on the client's health by checking the blood pressure takes precedence. Informing the charge nurse (Choice C) and completing an incident report (Choice D) are important steps to take after addressing the immediate health concern of the client.
A nurse administers a dose of metformin to a client instead of the prescribed dose of metoclopramidWhich of the following actions should the nurse take first?
- A. Report the incident to the charge nurse.
- B. Notify the provider.
- C. Check the client's blood glucose.
- D. Fill out an incident report.
Correct Answer: C
Rationale: The correct answer is C: Check the client's blood glucose. This is the first action the nurse should take because metformin is used to treat diabetes and can lower blood sugar levels. Checking the client's blood glucose will help assess if the client is experiencing hypoglycemia due to the medication error. Reporting the incident to the charge nurse (A) and filling out an incident report (D) are important steps, but assessing the client's immediate condition takes priority. Notifying the provider (B) can be done after ensuring the client's safety. The other options are not relevant to addressing the immediate concern of potential hypoglycemia.
Which of the following medication prescriptions should the nurse identify as being complete?
- A. Tetracycline 200 mg PO
- B. Epoetin alfa 150 units/kg three times weekly
- C. Digoxin 0.25 mg PO daily
- D. Cimetidine PO twice daily
Correct Answer: C
Rationale: The correct answer is C, Digoxin 0.25 mg PO daily. This prescription is complete because it includes the name of the medication (Digoxin), the dosage (0.25 mg), the route (PO), and the frequency (daily). The dosage is specified, and clear instructions are given for administration.
Choice A is incomplete as it lacks frequency information. Choice B is incomplete as it lacks the frequency and route of administration. Choice D is incomplete as it lacks the medication name and dosage information. Choices E, F, and G are not provided.
How many mL/h should the nurse set the IV infusion pump to deliver half the total volume of lactated Ringer's (4,080 mL) in the first 8 hours?
- A. 200 mL/h
- B. 225 mL/h
- C. 250 mL/h
- D. 255 mL/h
- E. 275 mL/h
Correct Answer: D
Rationale: The correct answer is D: 255 mL/h. To deliver half of 4,080 mL in 8 hours, you need to administer 2,040 mL in 8 hours. To calculate the infusion rate, divide the total volume by the total time: 2,040 mL ÷ 8 hours = 255 mL/h. This rate ensures half of the total volume is infused within the specified time frame.
Choice A (200 mL/h) is too slow, as it would not deliver half the volume in 8 hours. Choices B, C, and E exceed the required rate and would deliver more than half the volume in 8 hours.
