Question

glucose in the tube feeding formula from the problem above? 5. What is the Critical Thinking Question (5 pts.) (You may use the back of the page to write your answer if needed). Today you have learned about the Lymphatic System and the White Blood Cells. Here is a question for you to work on Mrs. X was getting out of her car, when she slammed the car door on her knee, hurting it quite badly, even though there was no broken skin or bleeding. The knee became very swollen and painful within the first couple of hours, making it difficult to walk, so Mrs. X went to an emergency room to check her knee. to a Explain what happened here at the cellular level (use the inflammatory reaction cascade to answer step by step). When Mrs. X came to the ER, the X-rays of her knee were taken, revealing no fracture. Doctor recommended ice packs to 1. 2. hee th, the as or rle help reduce the swelling. What is the purpose of the ice packs? Explain at the cellular level. The doctor also prescribed lbuprofen for inflammation and pain. Explain how that helps at the cellular level. 3.

Answer 1

1. ANS: The slamming of the door on the knee has caused trauma, which has caused inflammatory process to start, ultimately leading to swelling.  

When inflammation occur white blood cells releases chemical substances in the blood or the traumatized tissue. Some of these chemicals cause leakage of fluids into the interstitial space, causing the swelling.

2. ANS: Applying any cold objects, like ice or cold water on the swollen area causes vasoconstriction, which reduces the blood flow, and also the chemicals that are causing swelling in the tissue. This helps in reducing the swelling; it helps in the reduction of pain too, by causing numbness. Their vasoconstrictor effect helps in reducing the leakage of tissue fluid. Decreases cell metabolism and helps to prevent tissue death and it can helps in slowing down the rate of production of inflammatory factors.

3. ANS: Ibuprofen is a NSAID (non steroidal anti inflammatory drug). It stops the body from producing large amounts of prostaglandins during injury. It blocks the effect of chemicals called COX (cyclo oxygenase) enzymes which is responsible for production of prostaglandins. Ibuprofen blocks these enzymes and work at the injury site to help relieve pain and reduce pain and inflammation.
