Which component of the complete blood count reflects the blood's oxygen-carrying capacity?
Hemoglobin
Platelet count
White blood cell count
Red cell distribution width
Hemoglobin is the protein in red blood cells responsible for transporting oxygen. It directly reflects the oxygen-carrying capacity of the blood.
What is the primary function of platelets in the circulatory system?
Initiate blood clotting
Carry nutrients to tissues
Transport oxygen
Chemical signaling in immune response
Platelets aggregate at sites of vascular injury to initiate clot formation. This hemostatic function prevents excessive bleeding.
An elevated white blood cell count (leukocytosis) most commonly indicates which condition?
Thrombocytopenia
Hyperviscosity
Anemia
Infection or inflammation
Leukocytosis often reflects the body's response to infection or inflammation. White blood cells multiply to fight pathogens or inflammatory stimuli.
A low hematocrit value is most indicative of which condition?
Anemia
Polycythemia
Thrombocytosis
Leukemia
Hematocrit measures the proportion of red blood cells in blood. A low hematocrit indicates reduced red cell mass, which is characteristic of anemia.
What does an increased red cell distribution width (RDW) indicate?
Variation in red blood cell size
Variation in plasma volume
Variation in white blood cell size
Variation in platelet size
RDW measures the range of sizes (anisocytosis) of red blood cells. An elevated RDW indicates significant variability in RBC size.
A CBC reveals a white blood cell count of 3,000/µL. What term describes this finding?
Thrombocytopenia
Leukopenia
Leukocytosis
Erythrocytosis
A WBC count below the normal range (<4,000/µL) is termed leukopenia. It indicates a decreased number of circulating white cells.
An absolute neutrophil count (ANC) of less than 500/µL places a patient at high risk for:
Hemolysis
Bleeding episodes
Thrombotic events
Severe infection
Neutrophils are key in fighting bacterial infections. An ANC below 500/µL signifies severe neutropenia and high infection risk.
Which cytogenetic marker is most closely associated with chronic myelogenous leukemia (CML)?
Deletion 5q
t(8;14) MYC rearrangement
Philadelphia chromosome
Trisomy 21
The Philadelphia chromosome, a t(9;22) translocation, creates the BCR-ABL fusion protein driving CML. It is a hallmark for diagnosis.
A patient on chemotherapy presents with fever and an ANC of 400/µL. As an EMT, the highest priority is to:
Initiate broad-spectrum IV antibiotics and arrange rapid transport
Monitor vital signs and observe
Administer a platelet transfusion
Provide oral fluids and rest
Febrile neutropenia is a medical emergency. Prompt IV antibiotics and rapid transport to definitive care are essential to reduce mortality.
Which factor is the most significant modifiable risk for developing lung cancer?
Sedentary lifestyle
Tobacco smoking history
High fiber diet
Low body mass index
Tobacco smoking is the leading modifiable risk factor for lung cancer, accounting for the majority of cases worldwide.
Multiple myeloma often leads to hypercalcemia. Which symptom is most directly related to this electrolyte disturbance?
Hypotension
Tetany
Muscle cramps
Constipation and confusion
Elevated calcium levels can cause neuromuscular and gastrointestinal symptoms, including constipation, confusion, and lethargy.
A mean corpuscular volume (MCV) of 110 fL indicates which type of anemia?
Normocytic anemia
Microcytic anemia
Hemolytic anemia
Macrocytic anemia
MCV measures red blood cell size. A value above 100 fL is classified as macrocytic anemia, often due to B12 or folate deficiency.
Splenomegaly, lymphadenopathy, and elevated lymphocyte count are most characteristic of:
Chronic lymphocytic leukemia
Polycythemia vera
Essential thrombocythemia
Acute myelogenous leukemia
Chronic lymphocytic leukemia commonly presents with painless lymphadenopathy, splenomegaly, and elevated mature lymphocytes in the blood.
Cancer increases risk of venous thromboembolism mainly because tumors can:
Reduce hematocrit
Increase blood viscosity only
Secrete procoagulant substances
Lower platelet count
Many tumors release tissue factor and other procoagulants into circulation, creating a hypercoagulable state and raising thrombosis risk.
A platelet count of 50,000/µL primarily places a patient at risk for:
Severe infection
Bleeding
Hemolysis
Thrombosis
Thrombocytopenia (platelets <100,000/µL) increases bleeding risk, and counts below 50,000/µL carry a significant hemorrhage risk.
Which laboratory finding is most indicative of disseminated intravascular coagulation (DIC) in an acute promyelocytic leukemia patient?
Decreased prothrombin time (PT)
Elevated D-dimer levels
Elevated fibrinogen levels
Increased platelet count
DIC leads to widespread clotting and fibrinolysis, producing high levels of fibrin degradation products such as D-dimer. This is a sensitive marker for DIC.
Tumor lysis syndrome is characterized by which early laboratory abnormality?
Hypouricemia
Hyperuricemia
Hypophosphatemia
Hypokalemia
Rapid tumor cell breakdown releases intracellular contents including nucleic acids, which metabolize to uric acid, causing hyperuricemia in tumor lysis syndrome.
In polycythemia vera, increased blood viscosity most commonly leads to which presenting symptom?
Headache and visual disturbances
Acute shortness of breath only
Severe hypotension
Profuse sweating
Hyperviscosity from excess red cells impairs microcirculation, causing headaches, dizziness, and visual changes due to reduced cerebral and ocular perfusion.
A sickle cell patient in vaso-occlusive crisis typically requires which immediate EMT intervention?
Immediate antibiotic administration
IV fluids and aggressive pain management
Blood transfusion in the field
High-dose corticosteroids
Vaso-occlusive crises cause pain and dehydration. IV fluids help reduce sickling, and prompt analgesia is critical to manage severe pain episodes.
An acute leukemia patient presents with gingival bleeding, petechiae, and blasts on CBC. The EMT's immediate priority is to:
Give IV heparin to prevent clotting
Administer aspirin to reduce blasts
Control bleeding and arrange rapid transport
Restrict fluids to prevent overload
Thrombocytopenia and coagulopathy in acute leukemia put the patient at bleeding risk. EMTs should focus on hemorrhage control and rapid transport to definitive care.

Cheat Sheet

  1. Stages of Red Blood Cell Production - Your body's RBC factory runs like an assembly line, moving from hematopoietic stem cell through proerythroblast, erythroblast, reticulocyte, and finally to mature erythrocyte. Knowing each checkpoint helps you interpret lab markers and spot where anemia might sneak in. It's like tracking a package through every shipping scan! Read more on Nursing Hero
  2. Interpreting MCV and MCH - Mean Corpuscular Volume (MCV) and Mean Corpuscular Hemoglobin (MCH) are your clues for classifying anemia into microcytic, normocytic, or macrocytic types. A low MCV hints at iron trouble, normal MCV suggests acute blood loss or bone marrow issues, and high MCV points toward B12 or folate deficiencies. Pair these values with clinical context to paint the full picture! MCV & MCH Guide
  3. Managing Sickle Cell Crises - Sickle cell crises flare up with dehydration, infection, or stress, causing painful vaso-occlusion and organ strain. Rapid hydration, pain control, and treating underlying triggers are your frontline defenses. Think of it as easing a traffic jam in tiny blood highways! Sickle Cell Basics
  4. Recognizing Hodgkin Lymphoma Markers - Reed - Sternberg cells are the hallmark of Hodgkin lymphoma - giant binucleated cells with "owl's eye" nucleoli. Spotting these under the microscope clinches the diagnosis and guides therapy choices. It's like finding the VIP guest in a crowded party! Hodgkin Lymphoma Clues
  5. Pathophysiology of DIC - In Disseminated Intravascular Coagulation, your clotting system goes haywire, creating microthrombi while consuming clotting factors - so you end up bleeding and clotting simultaneously. Common triggers include sepsis, trauma, and obstetric emergencies. Managing DIC means tackling both sides: replace consumed factors and treat the root cause! DIC Survival Tips
  6. Common Transfusion Reactions - Transfusion reactions range from mild febrile chills to life-threatening hemolysis when antibodies attack mismatched cells. Recognize signs like fever, flank pain, or dark urine, stop the transfusion immediately, and follow protocol for fluids and supportive care. It's a game of "spot and stop" to keep patients safe! Transfusion Reaction Guide
  7. Neutropenic Fever Alert - Neutropenic fever shows up when oncology patients with low neutrophils develop a fever - this can spiral into sepsis if not treated swiftly. Empiric broad-spectrum antibiotics and hospitalization are your go-to moves. Think of it as deploying first-line defense before the invaders multiply! Neutropenic Fever Protocol
  8. Tumor Lysis Syndrome Essentials - Tumor Lysis Syndrome arises when massive cancer cell death floods the blood with electrolytes, causing hyperkalemia, hyperuricemia, and possible renal failure. Prevention with hydration, allopurinol, and close lab monitoring is key. It's chemistry class gone rogue - keep those levels in check! TLS Quick Reference
  9. Acute Chest Syndrome in Sickle Cell - Acute Chest Syndrome feels like pneumonia in sickle cell patients, triggered by sickling in lungs, infection, or fat emboli. Treatment bundles include oxygen, IV fluids, pain control, and antibiotics to prevent hypoxia and respiratory failure. It's a medical pit stop - rapid teamwork saves lives! Acute Chest Syndrome Help
  10. Role of EMT in Cancer Metastasis - Epithelial - Mesenchymal Transition (EMT) lets cancer cells shed their anchors, invade tissues, and spread to distant sites. Understanding EMT helps in developing targeted therapies to block metastasis. Think of it as cancer cells suiting up for a globe-trotting adventure - intercept them early! Dive into EMT Research
