Summary Introduction
Introduction:
A man in his late 20s (Andrew Hutchinson) met with an accident on his right arm. He has undergone surgery to repair it. Theproportion of lymphocytes and total leukocyte count found very low on a routine complete blood count checkup. His right finger was paining after some days of surgery. On examination, it was found that his right hand has redness, warmth, and edematous. Red streaks, radiating proximally on his right forearm, was visible. The doctor has prescribed a very high dose of antibiotics and the sling was prescribed, so a sling is applied. Nurses are advised to wear gowns and gloves while attending him.

Andrew Hutchinson, 27, had surgery to repair his right hand after it was crushed by his garage door. The routine complete blood count (CBC) performed on admission revealed both a dangerously low total leukocyte count and a low proportion of lymphocytes.
One day postsurgery, he complains of pain in his injured right ring finger. When examined, the affected finger and the dorsum of the right hand are red, warm, and edematous, and red streaks radiate proximally on his right forearm. High doses of antibiotics are prescribed, and a sling is applied to the affected arm. Nurses are instructed to wear gloves and gown for Andrew’s protection (called reverse isolation) when tending to him.
How might the low lymphocyte count, orders for antibiotic therapy, and reverse isolation be related? Why is it important that Andrew not move the affected arm excessively (i.e., why was the sling ordered)?
Nigel is told he has type B blood. Which ABO antibodies does he have in his plasma? Which agglutinogens are on his RBCs? Could he donate blood to an AB recipient? Could he receive blood from an AB donor? Explain.
Which of the following statements is valid concerning lymph fluid formation
1. Intermediate fiamnents attach lymphatic endothelial cells to sorrounding tissue
2. When the tissue swell due to the injury, gaps in the lymphatic capillaries open allowing fluid to flow from the blood capillary to the lymphatic capillary
3. Lymphatic capillaries are closed ended vessels
