A nurse is preparing to administer metronidazole 7.5 mg/kg PO to a client who weighs 146.7 lb. Available is metronidazole 500 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1"]
The first step is to convert the client's weight from pounds (lb) to kilograms (kg).
146.7 lb ÷ 2.2 lb/kg = 66.68 kg
Next, the nurse should calculate the total dose of metronidazole the client needs.
7.5 mg/kg x 66.68 kg = 500.1 mg
Since the available tablets are 500 mg each, the nurse should administer:
500.1 mg ÷ 500 mg/tablet = 1 tablet (rounded to the nearest whole number)

Correct Answer is D
Explanation
Answer: D. with "EP116" stamped on one side of the tablet.
Rationale:
A. As a round, white tablet:
While furosemide may come in white tablet form, this description alone is not specific enough to identify the correct medication. Multiple medications can appear as round white tablets, so this option lacks distinguishing detail.
B. As a multicolored capsule:
Furosemide 20 mg is not typically manufactured as a multicolored capsule. This appearance is more commonly associated with other medications, and using this could increase the risk of medication administration error.
C. with Furosemide 20 mg printed on the side of the capsule:
Furosemide tablets are usually stamped with manufacturer-specific codes, not printed with the full name and dosage. Capsules with this exact labeling are not standard for furosemide 20 mg.
D. with "EP116" stamped on one side of the tablet:
This is the specific imprint used to identify furosemide 20 mg tablets. The imprint “EP116” confirms the correct drug and dose and is used to verify medication identity before administration.
Correct Answer is ["0.5"]
Explanation
To calculate the volume to be administered, the nurse should first divide the prescribed dose (100 mg) by the concentration of the available medication (200 mg/5 mL): 100 mg / (200 mg/5 mL) = 2.5 mL. Since there are 5 mL in a teaspoon, the parent should administer 2.5 mL / 5 mL/teaspoon = 0.5 teaspoons per dose.
