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
Client's weight: 220 lb
Desired dose of enoxaparin: 1 mg/kg
Available strength of enoxaparin: 30 mg/0.3 mL
First, convert the client's weight from pounds to kilograms:
220 lb ÷ 2.20462 ≈ 99.79 kg
Now, calculate the desired dose of enoxaparin:
Desired dose = Dosage per kg × Weight Desired dose = 1 mg/kg × 99.79 kg ≈ 99.79 mg 30mg = 0.3ml
Therefore, 99.79mg = 99.79 * 0.3/30
=0.9979
Rounded off to the nearest whole number= 1ml
Correct Answer is ["50"]
Explanation
Total daily dose = 200 mg Frequency = Every 6 hours Total number of doses =24/6
=4 doses
Total dose = 200mg Per dose= 200mg/4
= 50mg
So, the nurse should administer 50 mg per dose.
