The central nervous system is better protected than any other system or organ in the body. Its main line of defense is the bones of the skull and spinal column, which create a hard physical barrier to injury. A fluid-filled space below the bones, called the syrnix, provides shock absorbance.

Unfortunately, this protection can be a double-edged sword. When an injury to the central nervous system occurs, the soft tissue of the brain and spinal cord swells, causing pressure because of the confined space. The swelling makes the injury worse unless it is rapidly relieved. Fractured bones can lead to further damage and the possibility of infection.

tatuchka [14]

1. what is the amount of the bolus dose, in both milligrams and milliliters, that you will administer in the first minute?
The doses is 0.9 mg/kg and the weight of the patient is 143 pounds. So, the total doses of drug needed will be:
Total doses= 0.9 mg/kg * 143 pounds * 0.453592 kg/pound= 58.37 mg.

10% of the doses will be given bolus for 1 min, so the amount would be:
Bolus doses= 10%*58.37 mg= 5.837 mg.
In mililiters, it would be: 5.837 mg * 1ml/mg= 5.837 ml.

2. what is the amount of the remaining dose that you will need to administer?
The remaining dose would be 90% of the total dose. You can either calculate it directly or subtract the bolus doses from the total doses.
Remaining doses= total doses- bolus doses= 58.37 mg- 5.837 mg= 52.533mg
