You are required to convert 250,000 units to milliliters, given that 100,000 units equals 2.5 mL. What is the correct conversion process and rationale?
Divide units by 100,000 to get mL; this is a units-to-mL conversion.
Multiply units by 100,000 to get mL; this is a units-to-mL conversion.
Add units to 100,000 to get mL; this is a units-to-mL conversion.
Subtract units from 100,000 to get mL; this is a units-to-mL conversion.
A medication order requires 100 mL/hr to be administered over 0.5 hours. What calculation should be performed to determine the correct volume per hour, and what is the rationale?
Divide volume by time in hours; this gives the correct rate.
Multiply volume by time in hours; this gives the correct rate.
Add volume to time in hours; this gives the correct rate.
Subtract time in hours from volume; this gives the correct rate.
A prescription calls for 0.12 g of a medication, and each tablet contains 60 mg. How many tablets should be administered, and what is the rationale for your calculation?
2 tablets; convert grams to mg, then mg to tablets.
1 tablet; convert grams to mg, then mg to tablets.
3 tablets; convert grams to mg, then mg to tablets.
4 tablets; convert grams to mg, then mg to tablets.
For high-alert medications administered via IV routes, what safety procedure should be followed before administration, and why?
Independent double-check by two nurses; because two-nurse verification is warranted.
Single nurse check; because double-check is not necessary.
Pharmacist verification only; because nurse verification is not required.
Patient self-verification; because nurse verification is optional.
