Question 1 of 5
A student nurse is having difficulty understanding the function of globulins. What information can the client provide to the student regarding the function of globulins?
Correct Answer: A
Rationale: Globulins function primarily as immunologic agents; they prevent or modify some types of infectious diseases. Globulins do not destroy invading organisms, participate in clot formation, or transport oxygen to the tissues.
Question 2 of 5
Undifferentiated cells that migrate to the thymus gland develop into which of the following?
Correct Answer: C
Rationale: The thymus gland is lymphatic tissue in the upper chest that contains undifferentiated stem cells released from bone marrow. Once the undifferentiated cells migrate to the thymus gland, they develop into T lymphocytes because they are thymus derived. The other options are distractors for this question.
Question 3 of 5
Macrophages attack and destroy foreign substances to the body. Where does this action occur?
Correct Answer: B
Rationale: As lymph passes through the node, macrophages attack and engulf foreign substances such as bacteria and viruses, abnormal body cells, and other debris. The other options are incorrect.
Question 4 of 5
Albumin is a protein in the plasma portion of the blood. Under normal conditions, albumin cannot pass through the wall of a capillary. What significance is this for the vascular compartment?
Correct Answer: C
Rationale: Under normal conditions, albumin cannot pass through a capillary wall. Consequently, albumin helps maintain the osmotic pressure that retains fluid in the vascular compartment. Albumin does not push oxygen into the tissues of the body or absorb carbon dioxide for transport to the lungs. Albumin also does not retain leukocytes in the vascular compartment.
Question 5 of 5
A client is seeing the physician at the clinic and tells the nurse he is fatigued and short of breath with minimal exertion. What lab study may reflect a decrease in transport of oxygen?
Correct Answer: A
Rationale: Erythrocytes function is to transport oxygen. Leukocytes protect against infection. Platelets participate in clotting blood, and albumin affects intravascular osmotic pressure.
