The nurse needs to administer doxycycline to a client. The prescription is for 300 mg, and the tablets available are 150 mg each. How many tablets would the nurse give?
2 tablets
1 tablet
3 tablets
0.5 tablet
The Correct Answer is A
Calculation:
- Identify the ordered dose and tablet strength
Ordered Dose: 300 mg
Tablet Strength: 150 mg per tablet
- Calculate the number of tablets to administer
Number of Tablets = Ordered Dose ÷ Tablet Strength
Number of Tablets = 300 ÷ 150
= 2

Correct Answer is C
Explanation
Calculation:
- Identify the total volume and infusion rate
Total Volume: 900 mL
Infusion Rate: 75 mL/hr

Time (hours) = Total Volume ÷ Infusion Rate
Time = 900 ÷ 75
= 12 hours
Correct Answer is D
Explanation
A. Check the medication's expiration date after administration: Verifying expiration after giving a medication does not prevent the administration of an ineffective or potentially harmful drug. Safety requires checking the expiration before administration.
B. Ask the client if they have any questions about the medication after administration: While educating the client is important, this should occur before the medication is given to ensure understanding, consent, and safe use. Post-administration questions cannot prevent errors.
C. Confirm the medication with the client's family: Family input may be helpful, but the primary responsibility for verifying the correct medication lies with the nurse and the prescribed orders. Family confirmation cannot replace independent verification.
D. Review the medication label against the MAR at the client's bedside: Comparing the medication label with the MAR at the bedside ensures the right client, drug, dose, route, and time, adhering to the “five rights” of medication administration. This verification is the most important step to prevent medication errors.
