A nurse is reviewing new prescriptions for a patient who was just admitted. For
which of the following prescriptions should the nurse obtain further clarification
from the provider?
A. Desvenlafaxine 50 mg PO qd
B. Ketorolac nasal spray 1 spray in each nostril every 6 hours PRN moderate pain
C. Oxycodone 10 mg PO every 4 hours PRN severe pain
D. Regular insulin 35 units subcut 30 min ac - ANSWERS-A. Desvenlafaxine 50 mg
PO qd
Explanation: The nurse should identify that certain abbreviations can be
misinterpreted and can result in medication errors. The abbreviation "qd" (daily)
,can be misinterpreted as "qid" (four times daily), which could result in improper
medication administration and potential medication toxicity. The nurse should
clarify the prescription with the provider.
A nurse is preparing to administer furosemide 20 mg IM. Available is furosemide
injection 10 mg/mL. How many mL should the nurse administer?
(Round answer to nearest whole number. Use a leading zero if it applies. Do not
use a trailing zero.) - ANSWERS-Answer: 2 mL
A nurse is preparing to administer midazolam 0.07 mg/kg IM to a patient who
weighs 50 kg. Available is midazolam 5 mg/mL. How many mL should the nurse
administer?
(Round answer to nearest tenth. Use a leading zero if it applies. Do not use a
trailing zero.) - ANSWERS-Answer: 0.7 mL
Follow these steps for the Ratio and Proportion method of calculation:
Step 1: What is the unit of measurement the nurse should calculate? mg
Step 2: Set up an equation and solve for X.
X = Dose per kg × Client's weight in kg
X mg = 0.07 mg/kg × 50 kg
X mg = 3.5 mg
Step 3: What is the unit of measurement the nurse should calculate? mL
,Step 4: What is the dose the nurse should administer? Dose to administer =
Desired 3.5 mg
Step 5: What is the dose available? Dose available = Have 5 mg
Step 6: Should the nurse convert the units of measurement? No
Step 7: What is the quantity of the dose available? 1 mL
Step 8: Set up an equation and solve for X.
Have/Quantity = Desired/X
5 mg/1 mL = 3.5 mg/ X mL
X mL = 0.7 mL
Step 9: Round if necessary.
Step 10: Determine whether the amount to administer makes sense. If there are 5
mg/mL and the prescription reads 0.07 mg/kg, it makes sense to administer 0.7
mL. The nurse should administer midazolam 0.7 mL IM.
A nurse is preparing to administer eszopiclone 2,000 mcg PO to a client. How
many mg should the nurse administer?
(Round to the nearest whole number. Use a leading zero if it applies. Do not use a
trailing zero.) - ANSWERS-Answer: 2 mg
Follow these steps for the Ratio and Proportion method of calculation:
Step 1: What is the unit of measurement the nurse should calculate? mg
Step 2: What is the dose the nurse should administer? Dose to administer =
Desired 2,000 mcg
, Step 3: What is the dose available? Dose available = Have 1 mg
Step 4: Should the nurse convert the units of measurement? Yes (mcg does not
equal mg)
1,000 mcg/1 mg = 2,000 mcg/X mg
X mg = 2 mg
Step 5: Round if necessary.
Step 6: Determine whether the amount to administer makes sense. If the
prescription reads 2,000 mcg and 1,000 mcg equals 1 mg, it makes sense to
administer 2 mg. The nurse should administer eszopiclone 2 mg PO.
A nurse is preparing to administer tobramycin 4 mg/kg/day IM divided in three
equal doses to a patient who weighs 60 kg. Available is tobramycin 40 mg/mL.
How many mL should the nurse administer per dose?
(Round to the nearest whole number. Use a leading zero if it applies. Do not use a
trailing zero.) - ANSWERS-Answer: 2 mL
Follow these steps for the Ratio and Proportion method of calculation:
Step 1: What is the unit of measurement the nurse should calculate? mg
Step 2: Set up an equation and solve for X.
X = Dose per kg × Client's weight in kg
X mg = 4 mg/kg × 60 kg
X mg = 240 mg
The dose is divided into three equal doses; therefore, divide X by 3.
