Lesson 2: Diagnostic Testing
Introduction
DIAGNOSTIC TESTS
- Tools to provide information about the client
- Screening during wellness check
- Confirm diagnosis
- Monitor illness
- Provide information response to treatment
Diagnostic Testing Phases
1.Pretest
2.Intratest
3.Posttest
PRETEST
● Instruct client and family about the procedure
● Explain the purpose of the test
● Instruct client and family about activity restrictions
● Instruct client and family on the reaction the
diagnostic test may happen
● Provide client with detailed information about
diagnostic testing equipment
, ● Inform client and family when test results will be

● Collect specimen
● Perform or assist with procedure
● Provide emotional and physical support
● Monitor client as needed
● Use correct labeling, storage, and transportation of

● Compare previous and current test results
● Modify nursing interventions as needed

Nursing Diagnoses
● Anxiety or fear related to possible diagnosis or

● Lack of knowledge (state diagnostic test) related to
insufficient information regarding the process for test
, Blood Tests
Venipuncture
- Puncture of a vein for collection of a blood
specimen
- Performed by phlebotomist
Complete Blood Count
● Hemoglobin
● Hematocrit (Hct)
● Red blood cell (RBC) count
● RBC indices
● Leukocyte
● White blood cell (WBC) count
● WBC differential
RED BLOOD CELL (RBC) COUNT
- The number of RBCs per cubic millimeter (mm³).
- Men: 4.6–6.0 million/mm³
- Women: 4.0–5.0 million/mm³
HEMOGLOBIN (HGB)
- Composed of a pigment (heme), which contains iron,
and a protein (globin).
- Men: 13.5–18 g/dL
- Women: 12–15 g/dL
