Blood Basics
This cell carries oxygen using hemoglobin
Erythrocyte (RBC)
These structures filter lymph and trap pathogens
Lymph nodes
This type of immunity is gained through vaccination
Active Immunity
These tiny red spots indicate low platelets
Petechiae
Priority intervention for a patient with platelet count of 20,000
Initiate bleeding precautions
This blood component is responsible for clotting
Platelet (Thrombocyte)
This condition causes swelling due to lymph fluid buildup
Lymphedema
This severe allergic reaction can cause airway obstruction
Anaphylaxis
This term describes difficulty breathing
Dyspnea
Priority concern in a patient with anaphylaxis
Airway (give epinephrine)
Low levels of this lab value indicate anemia
Hemoglobin (or Hematocrit)
This organ filters blood and helps fight infection
Spleen
These cells are responsible for antibody production
B Cells
This symptom is common in anemia due to low oxygen
Fatigue
Priority nursing action for neutropenic patient
Infection (neutropenic) precautions
This immature RBC indicates bone marrow activity
Reticulocyte
After lymph node removal, the nurse should avoid this in the affected arm
Blood pressure, IVs, and venipuncture
This condition occurs when the body attacks its own tissues
Autoimmune disease
These are large purple areas of bleeding under the skin
Ecchymosis
Which patient do you see first:
A. Hgb 8
B. Platelets 15,000 with bleeding gums
C. WBC 2,000
D. Mild fatigue
B (active bleeding + critically low platelets)
This protein is converted to fibrin during clot formation
Fibrinogen
This is the main type of cell found in lymphatic tissue
Lymphocytes (B&T Cells)
This HIV lab value indicates immune system strength
CD4 Count
This is bleeding into the joints, seen in hemophilia
Hemarthrosis
Which condition is most concerning:
A. Petechiae
B. Splenomegaly
C. Angioedema with difficulty breathing
D. Mild anemia
C (airway compromise = priority)
