A nurse is caring for a client with angina. The provider’s order reads, “Give metoprolol (Lopressor) 300 mg/day PO in 2 divided doses. The tablets are available in 50-mg strength. How many tablets will the client receive per dose?
Explanation
Step 1: Identify the total daily dose. The healthcare provider’s order specifies a total of 300 mg per day.
Step 2: Determine the number of doses per day. The order states the medication should be given in "2 divided doses."
Step 3: Calculate the dosage for a single administration. To find the amount for one dose, divide the total daily dose by the number of doses: 300 mg / 2 doses = 150 mg per dose.
Step 4: Identify the strength of the available medication. The tablets on hand are 50 mg each.
Step 5: Calculate the number of tablets required for the single dose. Divide the required dose by the strength of the tablet: 150 mg / 50 mg = 3 tablets.
Final Answer: The client will receive 3 tablets per dose (which equals 150 mg per dose).
Test-Taking Strategy:
- Determine if the answer should be calculated for the total daily amount or for a single dose.
- Highlight the phrase "divided doses" to ensure you include the division step before calculating the number of tablets.
- Verify your final answer by multiplying the tablets per dose by the number of doses to see if it matches the total daily order.
Take-Home Points:
- Metoprolol is a beta-blocker that requires the nurse to assess the patient's heart rate and blood pressure before every administration.
- The term "divided doses" implies the total daily amount must be split into equal parts to maintain a steady therapeutic level in the bloodstream.
- Always double-check the medication suffix, as immediate-release metoprolol tartrate and extended-release metoprolol succinate have different dosing schedules and instructions.
