,NSG 3100 EXAM 3 PRACTICE GUIDE INSTRUCTIONS & QUESTIONS
How to Use This Guide
Read each question stem carefully, select your answer, then review the rationale to understand the clinical
reasoning behind the correct choice. Each question includes the tested concept and the source concept
from your course material. Questions marked with SATA require selecting all that apply.
Laboratory Values & Blood Components
1 The nurse is reviewing a patient's complete blood count (CBC). Which components are
included in a CBC? Select all that apply.
A RBCs
B Hemoglobin
C Hematocrit
D WBCs
E Differential WBC count
CORRECT ANSWER: A, B, C, D, E
Rationale: A complete blood count (CBC) includes RBCs, hemoglobin, hematocrit, WBCs, and differential
WBC count. This provides a comprehensive assessment of the cellular components of blood.
Tested Concept: CBC components
Source Concept: CBC: RBCs, hemoglobin, hematocrit, WBCs, and differential WBC count.
, 2 The nurse is teaching a patient about blood components. Which statement accurately
describes erythrocytes (RBCs)?
A They are responsible for inflammatory and immune responses
B They contain hemoglobin and transport oxygen
C They are necessary for blood clotting
D They destroy parasites and participate in allergic reactions
CORRECT ANSWER: B
Rationale: Erythrocytes (RBCs) contain hemoglobin and transport oxygen throughout the body.
Hemoglobin is the protein that binds and carries oxygen to tissues.
Tested Concept: Erythrocytes function
Source Concept: Erythrocytes (RBCs) contain hemoglobin and transport oxygen.
3 The nurse is reviewing a patient's laboratory results. What is the normal hemoglobin level
for an adult female?
A 10-14 g/dL
B 12-16 g/dL
C 14-18 g/dL
D 16-20 g/dL
CORRECT ANSWER: B
Rationale: The normal hemoglobin level for an adult female is 12-16 g/dL. For adult males, the normal
range is 14-18 g/dL. Hemoglobin is the protein in RBCs responsible for oxygen transport.
Tested Concept: Hemoglobin normal range — female
Source Concept: Normal adult female hemoglobin: 12-16 g/dL.
