A nurse is preparing to administer ceftazidime 750 mg IM. Available is ceftazidime 1 g vial.
The nurse reconstitutes the medication to yield a final concentration of ceftazidime 280 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2.7 "]
Volume (mL) = Desired dose / Concentration
Volume (mL) = 750 mg / 280 mg/mL
Volume (mL) rounded off to the nearest tenth ≈ 2.7 mL

Correct Answer is ["1 "]
Explanation
Given:
- Desired dose of metronidazole: 7.5 mg/kg
- Client's weight: 146.7 lb
- Available strength of metronidazole tablets: 500 mg
First, convert the client's weight from pounds to kilograms:
146.7 lb ÷ 2.20462 = 66.57 kg (rounded to the nearest hundredth)
Now, calculate the desired dose of metronidazole:
Desired dose = Dosage per kg × Weight Desired dose = 7.5 mg/kg × 66.57 kg Desired dose ≈ 498.775 mg
Next, find out how many tablets are needed to achieve this dose: Number of tablets = Desired dose / Strength per tablet
Number of tablets = 498.775 mg / 500 mg Number of tablets ≈ 0.997
Since we cannot administer a fraction of a tablet, the nurse should administer 1 tablet of metronidazole.
Correct Answer is A
Explanation
A. Kilogram - Correct. Kilogram is a metric unit of weight commonly used in healthcare settings to document weight.
B. Milliliter - Milliliter is a metric unit of volume, not weight.
C. Pound - Pound is not a metric unit; it's an imperial unit of weight.
D. Ounce - Ounce is also not a metric unit; it's an imperial unit of weight.
