Med Surg 2 Exam 1 Questions With Correct Review Solution A+ 2024
What is perfusion? (Iggy 778) - Answer-The total arterial blood flow through the tissues
... [Show More] (peripheral
perfusion) and blood that is pumped by the heart (central perfusion).
What is clotting? - Answer-A complex, multi-step process by which blood forms a protein-based
structure (clot) in an appropriate area of tissue injury to prevent excessive bleeding while maintaining
whole-body blood flow (perfusion).
What are the components of blood (Iggy 779-781)? - Answer-Plasma:
RBC:
WBC
What is the job of plasma? - Answer-Thrombocytes.
Liquid portion of the blood that contains the cells. It is an ECF similar to the interstitial fluid found
between tissue cells, but containing much more protein.
The three major types of plasma proteins are albumin, globulins, and fibrinogen.
What is the job of RBC? - Answer-Erythrocytes - are the largest proportion of blood cells.
Produce hemoglobin. Iron is essential for Hgb because iron is the cellular substance to which oxygen
binds.
Hemoglobin can transport carbon dioxide and oxygen to different sites.
Lives for 120 days, but the body can regenerate.
What is the job of WBC? - Answer-Leukocytes - are formed in the bone marrow.
A nurse is caring for a client with diabetic ketoacidosis and documents that the client is experiencing
Kussmaul's respirations. Which pattern did the nurse observe? Select all that apply.
1. Respirations that are shallow
2. Respirations that are increased in rate
3. Respirations that are abnormally slow
4. Respirations that are abnormally deep
5. Respirations that cease for several seconds - Answer-2 & 4
What is the relationship between hemoglobin and iron? (Iggy p 779) - Answer-Hemoglobin has iron
anchored to it. Iron is an essential part of hemoglobin because iron is the cellular substance to which
oxygen binds.
What are the accessory organs of blood formation? (Iggy 780) - Answer-Spleen and liver are important
for blood production. Help regulate the growth of blood cells and form factors that ensure proper blood
clotting. Problems with either result in impaired hematologic function, which decreases adequate
perfusion or clotting to some degree.
Spleen → destroys old or imperfect RBCs, breaks down the hemoglobin released from these destroyed
cells for recycling, stores platelets, and filters antigens.
Liver → produces clotting factors. Large amounts of whole blood and blood cells are stored here. Also
stores extra iron within the protein ferritin. [Show Less]
