How to Use This Study Guide
Read each stem, choose your answer, then check the rationale directly below it. The correct
option is marked, and each wrong option is explained so you understand why it's wrong — not
just that it is. This guide contains comprehensive NCLEX-style questions covering all concepts
for NUR 254 Exam 3.
Laboratory & Diagnostic Testing
1 A nurse is reviewing laboratory results for a client. Which result should the nurse
report to the primary care provider immediately?
A Hgb = 16 g/dL for a male client
B Hct = 22% for a female client
C WBC = 9 × 10³/mL³
D Platelets = 300 × 10³/mL³
Why B is correct: A hematocrit of 22% is very low and can lead to death. The client's red
blood cells participate in oxygenation. The other options are within normal range.
A — Hgb 16 g/dL is within normal range for a male.
C — WBC 9 × 10³/mL³ is within normal range.
D — Platelets 300 × 10³/mL³ is within normal range.
