Heparin is supplied in bags that have 25,000 units / 250 mL. What is the concentration of Heparin?

1 unit per 1mL

10 units per 1 mL

100 units per 1 mL

1000 units per 1 mL

Answer and Explanation

The Correct Answer is C

A.   If the concentration were 1 unit/mL, then in 250 mL there would only be 250 units total, which is much lower than the provided 25,000 units.
B.   If the concentration were 10 units/mL, then in 250 mL there would be 2,500 units total, which is also much lower than the provided 25,000 units.
C.   If the concentration were 100 units/mL, then in 250 mL there would be 25,000 units total, which matches the provided information. However, while this seems plausible, it is not the answer we calculated.
D.   If the concentration were 1,000 units/mL, then in 250 mL there would be 250,000 units total, which is significantly higher than the 25,000 units provided.

Explanation

C. Multiple myeloma can weaken the immune system, making the client more susceptible to infections. Using fragrance-free gel soap can help to reduce the risk of skin irritation and infections.
D. Multiple myeloma can cause bone pain. Using analgesics as needed can help to manage this pain and improve the client's quality of life.

Correct Answer is C

Explanation

A. While blood vessel spasms can occur after a stroke, t-PA does not directly affect them.
B. Platelet aggregation is the process by which platelets stick together to form a clot. t-PA dissolves clots, but it does not prevent their formation.
C. Tissue plasminogen activator (t-PA) is a medication that can dissolve blood clots. In the case of a thrombotic stroke, a blood clot has blocked blood flow to the brain. By dissolving the clot, t-PA can restore blood flow and limit brain damage.
D. t-PA does not have any direct effect on the risk of infection in the brain.
