NUR 305 - Week 1 Test Questions Answered Correctly Latest Update 2025-2026
What percentage of blood is plasma? - Answers 55%
What are the three main blood cell types? - Answers Erythrocytes (RBCs), Leukocytes (WBCs),
Thrombocytes (platelets)
Where does hematopoiesis occur? - Answers Bone marrow
What does a CBC measure? - Answers RBCs, WBCs, platelets
What is primary hemostasis? - Answers Vessel constriction, platelet aggregation, plug
formation
What is secondary hemostasis? - Answers Activation of clotting factors, fibrin mesh, stable clot
Which test monitors heparin therapy? - Answers aPTT(activated partial thromboplastintime)
Which test monitors warfarin therapy? - Answers PT( (partial thrombin time)/INR
What labs are in a BMP(Basic metabolic panel)? - Answers Na, K, Cl, CO2, BUN, Creatinine(CR),
Glucose
What labs are in a CMP(Complete metabolic panel)? - Answers BMP(basic metabolicpanel) +
Liver Function Tests, Albumin, Calcium
What is homeostasis? - Answers The ability of the body to maintain a stable internal
environment.
What major components does the CBC(Complete blood count) measure? - Answers RBCs,
WBCs, platelets, hemoglobin, hematocrit.
What are the body's first-line defense mechanisms? - Answers Physical barriers such as skin
and mucous membranes.
Which immune system response is fast but nonspecific? - Answers Innate immunity
(neutrophils, macrophages)
Which immune cells provide long-term memory and specific response? - Answers Lymphocytes
(B cells and T cells).
What is the function of red blood cells? - Answers Transport oxygen, carry CO■, maintain acid-
base balance
What is the function of white blood cells? - Answers Defend against infection and foreign
substances.
What is Hemostasis? - Answers Hemostasis is the process of preventing blood loss from intact
, vessels and of stopping bleeding from a severed vessel, which requires adequate numbers of
functional platelets. Platelets nurture the endothelium and thereby maintain the structural
integrity of the vessel wall. Two processes are involved in arresting bleeding: primary and
secondary hemostasis
Primary hemostasis vs secondary hemostasis - Answers In primary hemostasis, the severed
blood vessel constricts. Circulating platelets aggregate at the site and adhere to the vessel and
to one another. An unstable hemostatic plug is formed. For the coagulation process to be
correctly activated, circulating inactive coagulation factors must be converted to active forms.
This process occurs on the surface of the aggregated platelets at the site of vessel injury.
Primary hemostasis involves the formation of a platelet plug at the site of injury, while
secondary hemostasis involves the coagulation cascade and the formation of a fibrin clot to
stabilize the initial plug.
