A client who weighs 176 pounds receives a prescription for morphine sulfate 0.1 mg/kg IM. The medication is available in a 10 mg/mL vial. How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.8"]
Convert weight: 176 pounds ÷ 2.2 = 80 kg
Dose required: 0.1 mg/kg × 80 kg = 8 mg
Volume to administer: 8 mg ÷ 10 mg/mL = 0.8 mL

Explanation
Total volume for 1800 calories: 1800 calories ÷ 200 calories/240 mL = 9
Volume needed: 9 × 240 mL = 2,160 mL
Correct Answer is ["0.42"]
Explanation
1. Determine the concentration of the reconstituted solution:
- The vial contains 0.3 mg of interferon beta-1b.
- It's reconstituted with 2 mL of sterile water.
- Concentration: 0.3 mg / 2 mL = 0.15 mg/mL
2. Calculate the volume to administer:
- The prescribed dose is 0.0625 mg.
- Concentration: 0.15 mg/mL
- Volume: (Desired Dose) / (Concentration) = 0.0625 mg / 0.15 mg/mL = 0.416666... mL
3. Round to the nearest hundredth:
- 0.416666... mL rounded to the nearest hundredth is 0.42 mL.
Therefore, the nurse should administer 0.42 mL.
