Question 1 of 5
A nurse is taking a medication history from a client who has a new prescription for levothyroxine. The nurse should instruct the client to wait 4 hr after taking levothyroxine before taking which of the following supplements?
Correct Answer: D
Rationale: The correct answer is D: Calcium. Levothyroxine absorption can be decreased by calcium when taken together. Calcium can bind to levothyroxine in the gastrointestinal tract, reducing its absorption. Waiting 4 hours after taking levothyroxine before consuming calcium ensures optimal absorption of levothyroxine. Ginkgo biloba, zinc, and vitamin C do not interfere significantly with levothyroxine absorption, making choices A, B, and C incorrect in this scenario.
Question 2 of 5
A nurse is preparing to titrate a continuous nitroprusside infusion for a client. The nurse should plan to titrate the infusion according to which of the following assessments?
Correct Answer: D
Rationale: The correct answer is D, Blood pressure. When titrating nitroprusside, the nurse should monitor blood pressure closely as it directly reflects the vasodilatory effects of the medication. By adjusting the infusion rate based on blood pressure readings, the nurse can maintain the desired therapeutic effect while minimizing the risk of hypotension or hypertension. Monitoring urine output (
A), cardiac output (
B), and stroke volume (
C) may provide valuable information but are not as direct indicators of the medication's effect as blood pressure.
Therefore, they are not the primary assessments to guide titration.
Question 3 of 5
A nurse is assessing a client who is taking warfarin. Which of the following findings should the nurse identify as the priority to report to the provider?
Correct Answer: A
Rationale: The correct answer is A: Melena. Melena is a sign of gastrointestinal bleeding, which can be a serious complication of warfarin therapy due to its anticoagulant effects. The nurse should prioritize reporting this finding to the provider to prevent further complications. Hair loss (choice
B) is not directly related to warfarin and is a less urgent concern. Fever (choice
C) and abdominal cramping (choice
D) are also not specific to warfarin therapy and may have various causes. Reporting melena promptly is crucial for the provider to assess and manage potential bleeding risks.
Question 4 of 5
A nurse is caring for a client who has received propofol during a colonoscopy. The nurse should monitor for which of the following as an adverse effect of the medication?
Correct Answer: B
Rationale: The correct answer is B: Decrease in respiratory rate. Propofol is a sedative-hypnotic medication commonly used for anesthesia. One of its common adverse effects is respiratory depression, leading to a decrease in respiratory rate. This occurs due to the central nervous system depressant properties of propofol, which can suppress the drive to breathe. Monitoring the client's respiratory rate is crucial to prevent respiratory complications.
Other choices are incorrect because:
A: Decrease in body temperature - Propofol does not typically affect body temperature.
C: Increase in heart rate - Propofol usually causes a decrease in heart rate due to its vasodilatory effects.
D: Increase in bowel function - Propofol does not directly impact bowel function.
Question 5 of 5
A nurse is preparing to administer a medication to a client. Using the rights of medication administration, which of the following actions should the nurse take to ensure the right medication is administered to the client?
Correct Answer: D
Rationale: The correct answer is D: Verify a written order with the medication administration record. This step ensures that the medication being administered matches the prescribed order, reducing the risk of errors. Documenting the full name post-administration (
A) does not prevent errors. Asking another nurse to check dosage (
B) may help but does not guarantee the right medication. Using client identifiers (
C) is important but does not directly ensure the medication is correct.
