A nurse is preparing to administer lorazepam 0.05 mg/kg IM to a client who weighs 132 lb. Available is lorazepam solution 2mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tent. Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["1.5"]
Convert the Client's Weight from Pounds to Kilograms:
1 kg = 2.205 lbs
Weight in kg = 132 lbs / 2.205 lbs/kg
Weight in kg ≈ 59.86 kg
Calculate the Total Dose of Lorazepam Needed:
Dose = 0.05 mg/kg x 59.86 kg
Dose ≈ 2.993 mg
Calculate the Volume of Lorazepam to Administer:
Available concentration = 2 mg/mL
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
Volume (mL) = 2.993 mg / 2 mg/mL
Volume (mL) ≈ 1.4965 mL
Round to the Nearest Tenth:
1.5 mL

Correct Answer is ["6.5"]
Explanation
Convert the Client's Weight from Pounds to Kilograms:
1 kg = 2.205 lbs
Weight in kg = 143 lbs / 2.205 lbs/kg
Weight in kg ≈ 64.85 kg
Calculate the Total Dose of Cyclosporine Needed:
Dose = 5 mg/kg x 64.85 kg
Dose ≈ 324.25 mg
Calculate the Volume of Cyclosporine to Administer:
Available concentration = 50 mg/mL
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
Volume (mL) = 324.25 mg / 50 mg/mL
Volume (mL) ≈ 6.485 mL
Round to the Nearest Tenth:
6.5 mL
Correct Answer is C
Explanation
A. A total 62.5 mL is available in this dose: The label states that each mL of the reconstituted solution contains 62.5 mg of methylprednisolone. However, the total volume available depends on the reconstitution process, and this option does not directly match the provided information.
B. This medication can be administered IM only: The label clearly states that the medication can be given both intramuscularly (IM) and intravenously (IV), making this option incorrect.
C. This medication should be protected from light: The label explicitly instructs to protect the medication from light, confirming this as the correct answer.
D. The medication is effective for 7 days after reconstitution: The label specifies that the medication should be used within 48 hours after reconstitution, not 7 days.
