Solution

Let’s address each question one by one.

Question 11

The question asks for the medical term for a percentage of erythrocytes (red blood cells) that is too high.
  1. Anemia - This refers to a deficiency of red blood cells or hemoglobin in the blood.
  2. Polycythemia - This is the condition characterized by an increased number of red blood cells.
  3. Hypoxemia - This refers to low levels of oxygen in the blood.
  4. Hyperanemia - This refers to an excess of blood in a particular area of the body.
Correct Answer: 2) polycythemia

Question 12

The question asks about the process that allows leukocytes (white blood cells) to leave the bloodstream and travel to other tissues.
  1. Immigration - This term is not used in this context.
  2. Chemotaxis - This is the movement of an organism or cell in response to a chemical stimulus.
  3. Diapedesis - This is the process by which leukocytes move out of the blood vessels and into tissues.
  4. Leukocytosis - This refers to an increase in the number of white blood cells in the blood.
Correct Answer: 3) diapedesis

Extra Insights

Did you know that polycythemia can occur as a response to living at high altitudes? When you’re up in the mountains, there’s less oxygen in the air, so the body compensates by creating more red blood cells to transport oxygen, leading to that higher percentage of erythrocytes! It’s nature’s cool way of helping you adapt and breathe easier.
Leukocytes aren’t just passively floating around; they’re like little ninjas! Through the process of diapedesis, they slip through the blood vessel walls to fight off infections. This ability to navigate through tissues is crucial in the body’s defense system, helping soldiers—oops, I mean immune cells—get to where they’re needed most!

Your patient is .. Mr. Jude Jacobs, a 68-year-old white retired mail carrier, who is known to have COPD and is on continual oxygen by nasal prongs. He has smoked two packs a day for his adult life. Last night, he was unable to sleep because of increased shortness of breath and cough. His cough produced yellow sputum. He had to sit upright in bed to be able to breathe. Vs are T 101.6F∘, P 98, R 36, BP 150/90. On examination, he is cyanotic and frightened and has nasal prongs in his nose. Air entry is diminished in both lungs, and there are crackles at both bases. You have been ordered to draw blood for ABGs and to measure the amount of air entering and leaving his lungs by using spirometry. Mr. Jacobs' FEV, was only 40% of the predicted value for a man of his age, height, and weight. Mr. Jacobs' FVC also was reduced because of the fibrotic effects of repeated infections on his lung tissues reducing the volume in his airways. When he was off O2, Mr. Jacobs' O2 levels were below 50% of normal. Even with nasal prongs and the administration of O2. his blood O2 levels were only 75% of normal.
