Blood clotting begins immediately when blood is drawn into a syringe but the time to form a clot dense enough to clog up a syringe varies based on numerous factors. These can include the amount of thrombin and fibrinogen present in the patient's blood (both compounds needed to make clots), the surrounding temperature and even how roughly the sample is handled (shaking a blood sample can speed up clotting).
Also syringes sometimes coated or contain anti-clotting compounds (such as citrate- dextrose) to slow down the clotting process.
What else can I help you with?
Can you push the plunger all the way through the syrings while your thumb presses on the tip of the plunger?
No, it is not recommended to push the plunger all the way through the syringe while your thumb is pressing on the tip. This can cause the plunger to come out of the syringe barrel unexpectedly, potentially leading to spillage of the contents or injury. It's better to use the syringe as intended for safe and effective administration.
What is the difference between injection and syringe?
An injection is a method of delivering medication or fluids into the body, while a syringe is a tool used to administer injections by drawing or dispensing fluids. Injections can be given using various methods, such as with a syringe or through an IV drip.
What did you observe when you tried to push the plunger of the syringe while your hand was pressing against its end?
When pushing the plunger of the syringe while my hand was pressing against its end, I noticed that the resistance was significantly increased. This resistance occurred because the pressure applied at the end of the syringe was transmitted through the liquid inside, making it harder to push the plunger.
Can AB donor be transfuse into a type O recipient?
While type O blood is known as being the universal donor, it is not a universal recipient. Type O blood can be transfused into any other blood type, but someone with type O blood could only receive a transfusion of type O blood.
Can you push the plunger all way through the syringe while your thumb presses on the tip of the plunger why or why not?
No, you cannot push the plunger all the way through the syringe while your thumb presses on the tip of the plunger. This is because the plunger is designed to create a seal within the barrel of the syringe, and pressing on the tip prevents the plunger from moving forward. The pressure created by your thumb would counteract the force needed to push the plunger, making it impossible to fully depress it.
What happens to the marshmallows in the syringe as i push the plunger down What happens to the marshmallows in the syringe as i pull the plunger up?
When you push the plunger of a syringe down into a marshmallow, it puffs up with air. When you pull the plunger of the syringe up while it is in the marshmallow, it will shrink.
Why white blood cells pass through capillaries while red blood cells not?
Both red and white blood cells pass through the capillaries.
What has three hearts?
An octopus has three hearts. Two pump blood through each of the two gills, while the third pumps blood through the body.
Is type a blood often referred to as the universal donor?
Yes, type O negative blood is often referred to as the universal donor because it can be transfused to patients of any blood type without causing an immune reaction. This is due to the absence of A and B antigens on the surface of O negative red blood cells. However, it's important to note that while O negative can be given to anyone, individuals with O negative blood can only receive O negative blood in transfusions.
Can you push the plunger all the way through the syringe while thumb presses on the tip of the plunger?
No, you cannot push the plunger all the way through the syringe if your thumb is pressing on the tip. The pressure from your thumb creates resistance that prevents the plunger from moving fully. Additionally, the design of syringes typically only allows the plunger to move to a certain point, ensuring it doesn't come out completely.
Is CMV blood-borne?
Cytomegalovirus (CMV) is primarily transmitted through bodily fluids, including blood, saliva, urine, and breast milk. While it can be present in blood, transmission through blood transfusions or organ transplants is relatively rare. Most commonly, CMV spreads through close contact with infected individuals or through sexual contact. Therefore, while it is technically blood-borne, other routes of transmission are more prevalent.
Can someone who has the blood type B negative donate blood to someone who is O positive?
Yes, someone with blood type B negative can donate blood to someone who is O positive. Blood type O is known as the universal blood donor because it can be transfused to patients with any blood type, while type B negative blood is considered a universal plasma donor, meaning the plasma can be transfused to patients of any blood type.
