- A. It's listed here on the medication sheet, so you should take it.'
- B. Go ahead and take it, and then I'll check with your doctor about it.'
- C. It wouldn't be listed here if it were not ordered for you.'
- D. Let me check on the order first before you take it.'

The nurse is reviewing a list of verbal medication orders. Which is the proper notation of the dose of the drug ordered?
- A. Levothyroxine .75 mg
- B. Levothyroxine .750 mg
- C. Levothyroxine 0.75 mg
- D. Levothyroxine 0.750 mg
Correct Answer: C
Rationale: Levothyroxine 0.75 mg illustrates the correct notation with a leading zero before the decimal point. Omitting the leading zero (as in A and B) may cause the order to be misread, resulting in a large drug overdose. Trailing zeros (as in D) are also incorrect.
During a period of time when the computerized medication order system was down, the prescriber wrote admission orders, and the nurse is transcribing them. The nurse is having difficulty transcribing one order because of the prescriber's handwriting. Which is the best action for the nurse to take at this time?
- A. Ask a colleague what the order says.
- B. Contact the prescriber to clarify the order.
- C. Wait until the prescriber makes rounds again to clarify the order.
- D. Ask the patient what medications he takes at home.
Correct Answer: B
Rationale: If a prescriber's order is illegible, the nurse should contact the prescriber for clarification to ensure accuracy. Asking a colleague or the patient does not verify the order, and waiting for rounds delays implementation.
During morning medication administration, the nurse discovered an error on the electronic MAR before the medication was given. Which action by the nurse is appropriate for this 'near-miss'?
- A. Correct the MAR error but say nothing because nothing happened.
- B. Notify the pharmacy about the error they almost caused.
- C. Report the near-miss using the facility's recommended protocol, and correct the error on the MAR.
- D. Report the near-miss to the next shift before the next dose is due.
Correct Answer: C
Rationale: Reporting a near-miss using the facility's protocol and correcting the MAR ensures errors are documented and addressed to prevent future incidents. The other options either ignore the error or delay reporting.
