Full Explanation
Calculation:
- Calculate the total number of doses the patient received.
Total doses = 4 doses/day × 5 days
= 20 doses.
Total amount of medication received = 45.25 g.
- Calculate the amount of medication per dose.
Amount per dose = Total amount (g) / Total number of doses
= 45.25 g / 20 doses
= 2.2625 g.
- Round the answer to the nearest hundredth.
= 2.26 g.

Of the doses on hand, you would choose___________ to administer the ordered dose
Ordered: Coumadin 7.5 mg PO daily
A. Coumadin 10 mg scored tablets
Coumadin 10 mg scored tablets: A 10 mg tablet exceeds the ordered dose of 7.5 mg. Although it's scored, splitting it in a way that gives exactly 7.5 mg would be imprecise and not ideal for accurate dosing.
B. Coumadin 1 mg scored tables
Coumadin 1 mg scored tablets: While these allow precise dosing, it would require administering multiple tablets (e.g., seven 1 mg tablets and one half), which increases pill burden and potential for error.
C. Coumadin injection 5 mg/via
Coumadin injection 5 mg/vial: The prescribed route is oral (PO), not parenteral. Using an injection would not comply with the prescribed route of administration.
D. Coumadin 5 mg scored tablets
Coumadin 5 mg scored tablets: The 5 mg scored tablet can be used to administer one whole 5 mg tablet and one-half tablet (2.5 mg), totaling 7.5 mg. This provides an accurate and convenient way to deliver the dose.

The physician ordered Cefprozil 87.5 mg po q12h for 10 days. What is the amount to administer?
Full Explanation
Ordered dose = 87.5 mg.
- Determine the concentration of the available medication from the label.
The label states that the concentration is 125 mg/5 mL.
Concentration = 125 mg / 5 mL
= 25 mg/mL.
- Calculate the volume to administer per dose using the formula:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
= 87.5 mg / 25 mg/mL
= 3.5 mL.
The hospital pharmacy receives a medication order for patient Jolene Smith, DOB 4/23/1986, for Keflex 250 mg qid. The medication order is dated today and is signed electronically by Ms. Smith's physician. What additional information is needed before this medication can be administered?
A. AP's name
AP's name: The physician has already signed the order electronically, which fulfills the requirement for authorized prescriber identification. The specific name may be on record in the electronic health system.
B. Number of refills
Number of refills: Refills are typically necessary for outpatient prescriptions, not for inpatient medication orders where the dosing is managed daily by healthcare staff.
C. Patient's social security number
Patient's social security number: A social security number is not required for medication administration. Patient identification can be verified with full name and date of birth.
D. Route of administration
Route of administration: The route (e.g., oral, IV) is essential for proper medication administration. Without this information, the nurse cannot safely give the drug. Keflex can be administered orally or intravenously, so clarification is necessary.
