When converting 3 ounces of medication to milliliters, what is the correct conversion?
A. 60 ml
Calculation: Ordered Dose = 3 ounces Conversion: 1 ounce = 30 mL Volume in mL = Number of ounces × 30 mL = 3 × 30 = 90 mL
B. 120 mL
Calculation: Ordered Dose = 3 ounces Conversion: 1 ounce = 30 mL Volume in mL = Number of ounces × 30 mL = 3 × 30 = 90 mL
C. 90 mL
Calculation: Ordered Dose = 3 ounces Conversion: 1 ounce = 30 mL Volume in mL = Number of ounces × 30 mL = 3 × 30 = 90 mL
D. 75 ml
Calculation: Ordered Dose = 3 ounces Conversion: 1 ounce = 30 mL Volume in mL = Number of ounces × 30 mL = 3 × 30 = 90 mL

A patient is prescribed 500 mg of a medication that is available as a 250 mg/5 mL solution. How many ml. should be administered?
A. 20 ml
Calculation: Ordered Dose = 500 mg Available Dose = 250 mg Available Volume = 5 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (500 / 250) × 5 = 2 × 5 = 10 mL
B. 15 ml
Calculation: Ordered Dose = 500 mg Available Dose = 250 mg Available Volume = 5 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (500 / 250) × 5 = 2 × 5 = 10 mL
C. 5 mL
Calculation: Ordered Dose = 500 mg Available Dose = 250 mg Available Volume = 5 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (500 / 250) × 5 = 2 × 5 = 10 mL
D. 10 ml
Calculation: Ordered Dose = 500 mg Available Dose = 250 mg Available Volume = 5 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (500 / 250) × 5 = 2 × 5 = 10 mL
Full Explanation
Calculation:
Ordered Dose = 500 mg
Available Dose = 250 mg
Available Volume = 5 mL
Volume to administer = (Ordered Dose / Available Dose) × Available Volume
= (500 / 250) × 5
= 2 × 5
= 10 mL
Why is it important for a nurse to use two patient identifiers before administering medication?
A. To ensure the correct medication is given to the right patient.
To ensure the correct medication is given to the right patient: Using two identifiers, such as name and date of birth, is a critical safety step to prevent medication errors. It ensures the medication matches the intended patient, reducing the risk of serious adverse events.
B. To comply with hospital policy on patient interaction.
To comply with hospital policy on patient interaction: While policies support patient safety, the primary purpose of using two identifiers is to prevent errors, not simply to follow policy.
C. To involve the patient in their care process
To involve the patient in their care process: Patient involvement is important, but verification with two identifiers focuses on safety and accuracy rather than engagement.
D. To confirm the patient's insurance details.
To confirm the patient's insurance details: Insurance information is unrelated to safe medication administration and does not prevent medication errors.

A medication order is for 0.5 g of a drug. The available dose is 250 mg tablets. How many tablets will you administer?
A. 1 tablet
Calculation: Ordered Dose = 0.5 g Available Dose = 250 mg Convert Ordered Dose to mg Ordered Dose = 0.5 × 1000 = 500 mg Number of tablets = Ordered Dose / Available Dose = 500 / 250 = 2 tablets
B. 3 tablets
Calculation: Ordered Dose = 0.5 g Available Dose = 250 mg Convert Ordered Dose to mg Ordered Dose = 0.5 × 1000 = 500 mg Number of tablets = Ordered Dose / Available Dose = 500 / 250 = 2 tablets
C. 2 tablets
Calculation: Ordered Dose = 0.5 g Available Dose = 250 mg Convert Ordered Dose to mg Ordered Dose = 0.5 × 1000 = 500 mg Number of tablets = Ordered Dose / Available Dose = 500 / 250 = 2 tablets
D. 4 tablets
Calculation: Ordered Dose = 0.5 g Available Dose = 250 mg Convert Ordered Dose to mg Ordered Dose = 0.5 × 1000 = 500 mg Number of tablets = Ordered Dose / Available Dose = 500 / 250 = 2 tablets
Full Explanation
Calculation:
Ordered Dose = 0.5 g
Available Dose = 250 mg
- Convert Ordered Dose to mg
Ordered Dose = 0.5 × 1000 = 500 mg
Number of tablets = Ordered Dose / Available Dose
= 500 / 250
= 2 tablets
