Explanation
Desired dose of isoniazid: 187 mg
Available strength of isoniazid injection: 100 mg/mL
First, find out how many milliliters of isoniazid correspond to the desired dose: Volume (mL) = Desired dose / Concentration
Volume (mL) = 187 mg / 100 mg/mL
Volume (mL) = 1.87 mL
Rounded off to the nearest tenth = 1.9 ml
Correct Answer is ["3"]
Explanation
Given:
- Desired dose of bumetanide: 1.5 mg
- Available strength of bumetanide tablets: 0.5 mg
First, find out how many tablets are needed:
Number of tablets = Desired dose / Strength per tablet
Number of tablets = 1.5 mg / 0.5 mg/tablet Number of tablets = 3 tablets
So, the nurse should administer 3 tablets of bumetanide.
