NUR 2356 MULTIDIMENSIONAL CARE I - MDC 1 EXAM 2 WITH PRACTICE QUESTIONS
AND CORRECT ANSWERS/ MDC I EXAM 2 PREP 2026 (NEWEST UPDATE!!!)
Question 1
Which physiological state is the primary stimulant for the production of red blood cells
(erythropoiesis)?
A) Tachycardia
B) Tachypnea
C) Renin-angiotensin activation
D) Hypoxia
E) Hypertension
Correct Answer: D) Hypoxia
Rationale: Hypoxia (low oxygen levels in the tissues) is the primary stimulus for red blood
cell production. When the kidneys detect low oxygen, they release the hormone
erythropoietin, which travels to the bone marrow to stimulate the production of new red
blood cells to increase the blood's oxygen-carrying capacity.
Question 2
What are the four main components that make up the composition of human blood?
A) RBCs, WBCs, hemoglobin, and iron
B) RBCs, WBCs, platelets, and plasma
C) Plasma, solutes, glucose, and albumin
D) Platelets, reticulocytes, plasma, and water
E) RBCs, WBCs, reticulocytes, and solutes
Correct Answer: B) RBCs, WBCs, platelets, and plasma
Rationale: Blood is a specialized body fluid. It has four main components: plasma (the
liquid portion), red blood cells (erythrocytes), white blood cells (leukocytes), and platelets
(thrombocytes). Each plays a distinct role in transport, immunity, and clotting.
Question 3
A nurse is reviewing the composition of a patient's plasma. What percentage of plasma is
typically composed of water?
A) 10%
B) 50%
C) 75%
D) 90%
E) 99%
Correct Answer: D) 90%
Rationale: Plasma is the liquid extracellular matrix of blood. It is composed of
approximately 90% water and 10% solutes. These solutes include proteins (like albumin
and globulins), glucose, clotting factors, electrolytes, hormones, and carbon dioxide.
