1. Administer 10 mg of Morphine every 4 hours in 100 ml of physiological solution. Presentations: 2.5mg vial in 2.5ml. 50mg vial in 2ml and 10mg vial in 10ml How many ml of physiological solution will there be and how many ml of Morphine using the presentation of 2.5mg in 2.5ml? How many vials should you use with the presentation of 2.5mg in 2.5ml? How many ml of physiological solution will there be and how many ml of Morphine using the presentation of 50mg in 2ml? How many ml of physiological solution will there be and how many ml of Morphine using the presentation of 10mg in 10ml?

Let's start with the calculations for each presentation:

### Presentation 1: 2.5mg in 2.5ml

1. Dose requirement: 10 \, \text{mg}
2. Volume requirement per dose using 2.5 mg vial: 10 \, \text{mg} \div 2.5 \, \text{mg/vial} = 4 \, \text{vials}
3. Morphine volume for the dose: 4 \times 2.5 \, \text{ml} = 10 \, \text{ml}
4. Volume of physiological solution: 100 \, \text{ml} - 10 \, \text{ml} = 90 \, \text{ml}

**Answers for Presentation 1:**
- Morphine volume: 10 \, \text{ml}
- Physiological solution volume: 90 \, \text{ml}

### Presentation 2: 50mg in 2ml

1. Dose requirement: 10 \, \text{mg}
2. Calculation of Morphine volume needed: \frac{10 \, \text{mg}}{50 \, \text{mg}} \times 2 \, \text{ml} = 0.4 \, \text{ml}
3. Volume of physiological solution: 100 \, \text{ml} - 0.4 \, \text{ml} = 99.6 \, \text{ml}

**Answers for Presentation 2:**
- Morphine volume: 0.4 \, \text{ml}
- Physiological solution volume: 99.6 \, \text{ml}

### Presentation 3: 10mg in 10ml

1. Dose requirement: 10 \, \text{mg}
2. Morphine volume for the dose: 10 \, \text{ml}
3. Volume of physiological solution: No additional physiological solution needed

**Answers for Presentation 3:**
- Morphine volume: 10 \, \text{ml}
- Physiological solution volume: 90 \, \text{ml} (to keep the total administration volume at 100 \, \text{ml})

Therefore, the calculations using the three different presentations of Morphine have shown the Morphine and physiological solution volumes required for each scenario.

\textbf{Final answers:}
- For Presentation 1: Morphine volume - 10 \, \text{ml}, Physiological solution volume - 90 \, \text{ml}
- For Presentation 2: Morphine volume - 0.4 \, \text{ml}, Physiological solution volume - 99.6 \, \text{ml}
- For Presentation 3: Morphine volume - 10 \, \text{ml}, Physiological solution volume - 90 \, \text{ml}
