Error Prone Abbreviations - Pharmacy Technician Certification Exam Ptce

1. What is the correct way to write a dose of .5 mg to comply with safe leading zero rules?

   0.5 mg. Safe notation requires a leading zero for fractional doses to ensure clarity and avoid errors in reading the decimal.

2. Find and correct the trailing zero error in this dose: 0.50 mg.

   0.5 mg. Removing the trailing zero eliminates the risk of the dose being misread as a higher amount without the decimal.

3. Find and correct the dangerous abbreviation in this sig: Warfarin 5 mg QOD.

   Warfarin 5 mg every other day. Correcting QOD to 'every other day' eliminates the risk of misinterpretation as daily administration.

4. What is the correct way to write a dose of 0.5 mg to avoid a leading zero error?

   0.5 mg. Including a leading zero before the decimal point prevents misinterpretation of the dose as 5 mg if the point is overlooked.

5. What is the unsafe practice called when writing $.5$ mg instead of $0.5$ mg?

   Missing leading zero. Omitting the leading zero can cause the decimal to be missed, leading to a tenfold overdose error.

6. Which is correct for a dose less than 1: $0.2$ mL or $.2$ mL?

   $0.2$ mL. Doses below 1 require a leading zero to enhance visibility of the decimal and prevent misinterpretation.

7. What is the correct way to write "international units" to avoid a dangerous abbreviation error?

   international units (write out; do not use IU). Writing out 'international units' eliminates misinterpretation of IU as IV or other error-prone readings.

8. Find and correct the dangerous abbreviation in this dose: Levothyroxine 25 ug daily.

   Levothyroxine 25 mcg daily. Changing ug to mcg reduces the risk of misreading as mg, which could result in significant dosing mistakes.

9. What is the correct way to write "every other day" to avoid the dangerous abbreviation "QOD"?

   every other day. Writing 'every other day' prevents QOD from being mistaken for QD, avoiding daily dosing errors.

10. Which option correctly writes a dose: $0.05$ mg or $.05$ mg?

    $0.05$ mg. Leading zeros are required for safety to prevent overlooking the decimal in small doses.

11. What is the correct way to write "micrograms" to avoid confusion with mg?

    mcg (or write out micrograms). Using mcg or 'micrograms' avoids handwritten confusion between ug and mg, preventing thousandfold errors.

12. Which option correctly writes a whole-number volume: $3$ mL or $3.0$ mL?

    $3$ mL. Trailing zeros are avoided in whole volumes to eliminate risks of tenfold measurement errors.

13. Find and correct the zero error in this order: Digoxin $.125$ mg PO daily.

    Digoxin $0.125$ mg PO daily. Adding leading zeros in orders ensures fractional doses are clearly distinguished from whole numbers.

14. Find and correct the zero error in this order: Morphine $10.0$ mg IV once.

    Morphine $10$ mg IV once. Correcting trailing zeros in orders reduces the chance of decimal misinterpretation in medication administration.

15. Find and correct the dangerous abbreviation in this sig: Insulin glargine 10 U SC daily.

    Insulin glargine 10 units SC daily. Replacing U with 'units' avoids confusion where it might be interpreted as part of the numeral, causing overdoses.

16. Which is correct to avoid a trailing zero error: $5.0$ mg or $5$ mg?

    $5$ mg. Whole-number doses should not include trailing zeros to avoid errors where the decimal is ignored.

17. What is the correct way to write "daily" to avoid the dangerous abbreviation "QD"?

    daily. Writing 'daily' prevents QD from being misread as QID, which means four times daily.

18. What is the correct abbreviation for "units" to avoid a dangerous abbreviation error?

    units (write out; do not use U). Writing out 'units' prevents misreading the abbreviation U as a zero, which could lead to dosing errors.

19. Find and correct the trailing zero error in this dose: 2.0 mL.

    2 mL. Trailing zeros after whole numbers can lead to tenfold dosing errors if the decimal point is missed.

20. What is the correct way to write a dose of 1.0 mg to avoid a trailing zero error?

    1 mg. Omitting the trailing zero for whole numbers prevents potential misreading as 10 mg if the decimal is not noticed.

21. Find and correct the dangerous abbreviation in this sig: Take 1 tablet QD.

    Take 1 tablet daily. Replacing QD with 'daily' avoids confusion with QID, ensuring the correct frequency is understood.

22. Find and correct the dangerous abbreviation: Vitamin D 1000 IU PO daily.

    Vitamin D 1000 international units PO daily. Correcting IU to 'international units' prevents potential confusion with IV in handwritten orders.

23. Identify the safer notation for one-half milligram: $0.5$ mg or $0.50$ mg.

    $0.5$ mg. Avoiding trailing zeros in fractional doses maintains safety by preventing misreading as a larger quantity.

24. What is the unsafe practice called when writing $1.0$ mg instead of $1$ mg?

    Trailing zero. Adding a trailing zero risks the dose being interpreted as ten times higher if the decimal is overlooked.

25. Find and correct the leading zero error in this dose: .25 mg.

    0.25 mg. A leading zero is essential for doses less than 1 to avoid confusion with higher whole-number doses.
