Normal Lab Values: Hematologic Flashcards
1
Q
Hgb
Hemoglobin: g/dL
A
Adult
- Male: 14-18
- Female: 12-16
- Pregnant: >11
Child
- 1-6 yr: 9.5-14
- 6-18 yr: 10-15.5
Infant/Newborn
- Newborn: 14-24
- 0-2 weeks: 12-20
- 2-6 months: 10-17
- 6 mo-1 yr: 9.5-14
Older Adult
- Values slightly decreased
Nursing Implications
- High altitude living increases values.
- Drug therapy can alter values.
- Slight Hgb decreases normally occur during pregnancy.
2
Q
Hct
Hematocrit: %
A
Adult
- Male: 42-52
- Female: 37-47
- Pregnant: >33
Child
- 1-6 yr: 30-40
- 6-18 yr: 32-44
Infant/Newborn
- Newborn: 44-64
- 2-8 weeks: 39-59
- 2-6 months: 35-50
- 6 mo-1 yr: 29-43
Older Adult
- Values slightly decreased.
Nursing Implications
- Abnormalities in RBC size may alter Hct values.
3
Q
RBC
Red Blood Cell Count: million/mm3
A
Adult
- Male: 4.7-6.1
- Female: 4.2-5.4
Child
- 1-6 yr: 4-5.5
- 6-18 yr: 4.5-5
Infant/Newborn
- Newborn: 4.8-7.1
- 2-8 weeks: 4-6
- 2-6 months: 3.5-5.5
- 6 mo-1 yr: 3.5-5.2
Older Adult
- Same as adult.
Nursing Implications
- Exercise and high altitudes can cause an increase in values.
- Pregnancy values are usually lower.
- Drug therapy can alter values.
4
Q
WBC
White Blood Cell Count: 1000/mm3
A
Adult
- Both sexes: 5-10
Child
- <!--=2 yr: 6.2-17</li-->
- >/=2 yr: 5-10
Infant/Newborn
- Newborn, term: 9-30
Older Adult
- Same as adult.
Nursing Implications
- Anesthetics, stress, exercise, and convulsions can cause increased values.
- Drug therapy can decrease values for 24-48 hr.
- Pregnancy (final month) and labor may cause increased WBC levels.
5
Q
Platelet Count: 1000/mm3
A
Adult
- Both sexes: 150-400
Child
- 150-400
Infant/Newborn
- Premature Infant: 100-300
- Newborn: 150-300
- Infant: 200-475
Older Adult
- Same as adult.
Nursing Implications
- Values may increase if living at high altitudes, exercising strenuously, or taking oral contraceptives.
- Values may decrease due to hemorrhage, DIC, reduced production of platelets, infections, prosthetic heart valves, and drugs (acetaminophen, aspirin, chemotherapy, H2-blockers, INH, Levaquin, streptomycin, sulfonamides, thiazide diuretics).
