Question 1 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 2 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.
Question 3 of 5
A client is in the hospital with a bleeding gastric ulcer and requires a blood transfusion. He has been typed and crossmatched for 2 units of packed red blood cells and found to have type O blood. What type of blood will the nurse administer to this client?
Correct Answer: D
Rationale: Those with type O blood can only receive type O blood. Clients with all other blood types can receive type O blood provided the Rh factor is compatible.
Question 4 of 5
The nurse is discussing vitamin replacement with a client in the clinic. Which vitamin should the nurse discuss with the client in order to increase the absorption of folic acid and iron?
Correct Answer: B
Rationale: Vitamin C enhances the absorption of folic acid and iron. Vitamin Bâ??â?? and folic acid are essential for the maturation of red blood cells. Vitamin B6 serves as a coenzyme in hemoglobin formation. Vitamin E protects blood cells from vitamin E-deficient hemolytic anemia.
Question 5 of 5
A client is being treated for anemia and has a hemoglobin level of 9.6 g/dL. What does the nurse understand is the basic nutritional component of heme in hemoglobin that the client may be deficient in?
Correct Answer: D
Rationale: Iron is the basic nutritional component of heme in hemoglobin. Folic acid is essential for the maturation of red blood cells. Copper (minute amount) is involved in the transfer of iron from storage to plasma.
