Hematology and Oncology Objective Flashcards
4 major causes of Anemia
- Increased demand required for rapid growth in infancy
Inadequate iron stores at birth
Mother iron deficient, premature infants - Insufficient iron intake
Excessive milk intake
Lack of iron-fortified formula/food - Blood loss
Acute or chronic - Decreased iron absorption
IBD, Crohns, Ulcerative Colitis
How to assess for Anemia
Development?
History?
Development:
Failure to Thrive
History:
Frequent bleeding
Frequent infections
Energy and activity levels
Food Intake
Laboratory findings Anemia
Routine screening when?
What blood test?
What is Reticulocyte Count?
What is ferratin?
Routine screening: 1year
CBC with differential
Hemoglobin electrophoresis
Reticulocyte Count
-Immature RBCs
Ferritin
-Protein that stores iron
Indirectly measures iron

Prolonged capillary refill
Weak pulses
Systolic heart murmur
Anemia: Clinical Manifestations
chronic
PJDF
Pallor
Jaundice
Delayed growth

Anemia Treatment
What kind of diet and supplement?
Treat underlying cause
Iron-rich diet
Oral iron supplements
Transfusions
Steps before giving a blood transfusion
Informed consent
two RNs verify blood product prior to administration
Administer within 30 minutes of delivery
Filter tubing
Slower infusion rate the first 15 minutes
Max infusion time over 4 hours
Vitals at baseline, at 15 minutes, then per institution policy
Blood Transfusion Considerations
Client’s religious or cultural background
Monitoring for adverse reaction during or after transfusion
Fever
Chills
Change in vital signs from baseline
Pruritus
Dyspnea
Pain
Decreased level of consciousness
Sickle Cell Disease
What kind of disorder?
25% chance of what?
50% chance of what?
characterized by what?
Autosomal recessive inherited blood disorder
25% chance will inherit two genes for sickle cell or two genes for Hemoglobin A
50% chance will inherit one gene for sickle cell and one normal gene, carrier state
Sickle Cell Trait
Characterized by the formation of long chains of hemoglobin when deoxygenated
Diagnosis of sickle cell
2
Newborn screening
Hemoglobin electrophoresis
Ethnicity of sickle cell
Affects approximately 100,000 Americans
*1 in 365 Black or African-American births
*1 in 16,300 Hispanic-American births
*1 in 13 Black or African-American births are BORN with Sickle Cell Trait
RBC Comparison
Normal? lifespan?
Sickle cell? lifespan?
Normal
-Soft, biconcave
-Lifespan: 120 days
Sickle cell
-RBC polymerize, forming stiff rods
-Lifespan: 20 days or less
Sickle Cell Disease:
Acute Complications
Acute Pain Episodes
Acute Chest Syndrome
Infection
Acute Anemia
Sickle Cell Disease: Acute Pain Episodes
Diagnosis?
Most common acute complication
Recurrent vaso-occlusion with ischemia
Diagnosis
Standard criteria: client’s reported pain
sickle cell management for pain
3
IV opioids: morphine, hydromorphone
(NSAID): ibuprofen or ketorolac
Warm compress, massage
