Answer:
Kindly check explanation as the question seems incomplete but the explanation should help.
Explanation:
Given the following :
Initial dosage of drug = 100mg
Halflife of drug = 6hours
After 18 hours, the percentage of drug that will be in the system should be :
Half-life is the time taken for a material to reduce to half of it's initial size.
Since half life = 6 hours
After 6 hours ; amount left = 100/2 = 50 mg
After 12 hours ; amount left = 50/2 = 25mg
After 18 hours ; amount left = 25/2 = 12.5mg
Hence, after 18 hours percentage left in system :
(Amount left / total initial amount) × 100%
(12.5 / 100) × 100%
0.125 × 100%
= 12.5%
The blood component that will need to be replaced is Platelets.
DIC stands for disseminated intravascular coagulation, it is a disease in which the proteins in the blood that regulate clotting becomes hyperactive. It leads to clot formation in the blood vessels which may clog them to prevent flow into the body parts and cause serious damage.
When the platelets are consumed in the formation of clots their shortage may cause an unstoppable bleeding from even a small cut. You may bleed spontaneously even without an injury. Its main cause may be due to an inflammation, injury, or due to prior illness.
