Chapter 20, Problem 4CCS
27-Year-Old Male with a Crushed Hand
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.
Relative to these observations:
4. Do you predict that Andrew's recovery will be uneventful or problematic? Why?

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
