Question 1 of 5
The nurse is preparing to administer medications to a 38-year-old client. Before administering the medications, the nurse understands which components make up the Five Rights of Medication Administration?
Correct Answer: B,C,D
Rationale: The correct answer is B, C, and D. Right Dose ensures the client receives the correct amount of medication, preventing under or overdosing. Right Drug ensures the client receives the intended medication, preventing errors. Right Patient ensures the medication is administered to the correct client, preventing mix-ups.
Choices A, E, F are not part of the Five Rights of Medication Administration, which are specifically focused on ensuring safe and accurate medication administration.
Question 2 of 5
A nurse is preparing an in-service program about preventing medication errors when transcribing a prescription. The nurse is using a dosage example of two tenths of a milligram. Which of the following examples should the nurse use to show appropriate transcription of this dosage?
Correct Answer: C
Rationale: The correct answer is C: 0.2 mg. When transcribing a dosage of two tenths of a milligram, it should be written as 0.2 mg to accurately represent the decimal point.
Choice A (2 mg) is incorrect as it represents a dosage that is 10 times greater.
Choice B (0.20 mg) is incorrect as it adds unnecessary zeros after the decimal point.
Choice D (2.0 mg) is incorrect as it implies a dosage that is 10 times greater.
Therefore, the most accurate and appropriate representation of two tenths of a milligram is 0.2 mg, making choice C the correct answer.
Question 3 of 5
The nurse is assigned a 49-year-old female client in the primary care office for a wellness visit. The nurse assesses the client, documents nurses notes, and reviews the medication administration record for potential interactions. The nurse should be most concern with the potential interaction between __________and _________.
Correct Answer: A,F
Rationale: The correct answer is A (St. John's wort) and F (Warfarin) because St. John's wort is known to interact with many medications due to its effect on liver enzymes, potentially reducing the effectiveness of warfarin, leading to increased clotting risk. St. John's wort may decrease warfarin levels, increasing the risk of blood clot formation. Other choices have fewer interactions or different mechanisms of action, making them less likely to cause significant interactions with warfarin.
Question 4 of 5
The healthcare provider orders azithromycin (Zithromax) 1000mg to be given as a loading dose. The nurse understands that the purpose of this loading dose is to:
Correct Answer: C
Rationale: The correct answer is C: Achieve therapeutic drug levels more rapidly. A loading dose is given to quickly reach effective drug levels in the body. This is important for medications like azithromycin that require a certain concentration in the bloodstream to be effective.
Choice A is incorrect because a loading dose does not affect the duration of action, only the speed of reaching therapeutic levels.
Choice B is incorrect as it does not decrease the frequency of subsequent doses, but rather establishes the initial drug concentration.
Choice D is incorrect since the loading dose does not minimize adverse effects, but rather ensures the drug reaches therapeutic levels efficiently.
Question 5 of 5
The nurse is caring for a client who needs to have a peak drug level drawn. The client was given an oral medication 30 minutes ago. What is the best action by the nurse?
Correct Answer: A
Rationale:
Correct
Answer: A. Wait for at least another 30 minutes before calling to have the level drawn.
Rationale:
1. Peak drug levels are typically drawn 30 minutes to 2 hours after oral medication administration to capture the highest concentration.
2. Waiting an additional 30 minutes ensures the medication has had sufficient time to be absorbed and reach peak levels.
3. Drawing the level too soon may result in inaccurate results, potentially leading to incorrect dosing adjustments.
4. Waiting the additional time aligns with best practices for peak drug level monitoring.
Summary of Incorrect
Choices:
B. Scheduling in 8 hours is too delayed for peak levels.
C. Drawing the level immediately does not allow for the medication to reach peak levels.
D. Waiting until the next day is too late for peak levels to be accurately assessed.
