A nurse is preparing to administer testosterone cypionate 125 mg IM. Available is testosterone cypionate injection 200 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.63 "]
Given:
- Desired dose of testosterone cypionate: 125 mg
- Available strength of testosterone cypionate injection: 200 mg/mL
First, find out how many milliliters of testosterone cypionate correspond to the desired dose:
Volume (mL) = Desired dose / Concentration
Volume (mL) = 125 mg / 200 mg/mL Volume (mL) = 0.625 mL
Rounded off to the nearest hundredth= 0.63ml
So, the nurse should administer approximately 0.63 mL of testosterone cypionate per dose.

Correct Answer is ["2 "]
Explanation
Given:
- Desired dose of levothyroxine: 0.05 mg
- Available strength of levothyroxine tablets: 25 mcg
First, convert the desired dose from milligrams to micrograms:
0.05 mg = 50 mcg
Number of tablets = Desired dose / Strength per tablet
Number of tablets = 50 mcg / 25 mcg/tablet Number of tablets = 2 tablets
So, the nurse should plan to administer 2 tablets of levothyroxine.
