What is Disseminated Intravascular Coagulation (DIC)? - CORRECT ANSWER A pathological
activation of coagulation where blood clots consume coagulation proteins and platelets, leading
to abnormal bleeding.
What are common causes of DIC? - CORRECT ANSWER Any cause of tissue breakdown, with
sepsis being the most common.
What are the laboratory findings associated with DIC? - CORRECT ANSWER Decreased platelets
(<100,000), increased prothrombin time (PT), increased partial thromboplastin time (PTT),
decreased fibrinogen (<200 mg), and increased fibrin degradation products (FDP) or D-dimer.
What is the definition of anemia? - CORRECT ANSWER A deficiency of hemoglobin caused by
excessive blood loss, cell destruction, or deficiency in red blood cell production.
,What is the significance of Mean Corpuscular Volume (MCV) in anemia? - CORRECT ANSWER
MCV indicates the average size of red blood cells; it helps classify anemia as microcytic,
macrocytic, or normocytic.
What is the treatment for Idiopathic Thrombocytopenic Purpura (ITP)? - CORRECT ANSWER
Treatment may not be necessary, but exacerbations can be treated with steroids; severe cases
may require immunosuppressive drugs or splenectomy.
What are the components of the immune system? - CORRECT ANSWER Adaptive immunity,
innate immunity (including surface barriers and leukocytes), humoral immunity (IgA, IgD, IgE,
IgG, IgM, T and B cells), inflammation mediators (histamine, bradykinin, serotonin, leukotrienes,
prostaglandins), and the complement system.
What are the signs of tumor lysis syndrome (TLS)? - CORRECT ANSWER Dehydration, seizures,
cardiac dysrhythmias, and nausea/vomiting.
What is the treatment for hypercalcemia of malignancy? - CORRECT ANSWER Intravenous fluids
(IVF) and correction of imbalances.
What are the common reactions to blood products? - CORRECT ANSWER Infectious/viral
transfers, hypocalcemia, hyperkalemia, decreased 2,3-diphosphoglycerate, hypothermia,
transfusion-related acute lung injury (TRALI), and transfusion-associated circulatory overload
(TACO).
What is the role of Heparin in coagulation? - CORRECT ANSWER Heparin accelerates the
formation of Anti-thrombin III, inactivates thrombin, and prevents the conversion of fibrinogen
into fibrin.
What is the definition of critical-illness stress in relation to immunosuppression? - CORRECT
ANSWER It refers to the body's impaired ability to respond to stress due to factors like broken
skin barriers, impaired gag reflex, alterations in gastric pH, malnutrition, and drug interactions.
,What is the significance of the Oxyhemoglobin curve in respiratory physiology? - CORRECT
ANSWER It describes the relationship between oxygen saturation and partial pressure of
oxygen, indicating how readily hemoglobin binds to oxygen.
What is the primary purpose of dialysis? - CORRECT ANSWER To remove waste products and
excess fluid from the blood when the kidneys are unable to perform these functions.
What is the definition of hydrocephalus? - CORRECT ANSWER A condition characterized by an
accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain, leading to increased
intracranial pressure.
What are the types of shock classified in multisystem disorders? - CORRECT ANSWER
Hypovolemic, cardiogenic, distributive, and obstructive shock.
What is the purpose of mechanical ventilation? - CORRECT ANSWER To assist or replace
spontaneous breathing in patients who are unable to breathe adequately on their own.
What is the significance of cranial reflexes in neurological assessment? - CORRECT ANSWER
They help evaluate the integrity of the brainstem and the functioning of cranial nerves.
What are the common causes of acute renal failure? - CORRECT ANSWER Hypovolemia,
nephrotoxins, and obstructive uropathy.
What is the role of pulmonary function tests (PFTs)? - CORRECT ANSWER To assess lung
function and capacity, helping diagnose respiratory conditions.
What are common symptoms of dehydration? - CORRECT ANSWER Seizures, cardiac
dysrhythmias, nausea/vomiting (N/V)
, What is the primary treatment for dehydration? - CORRECT ANSWER Intravenous fluids (IVF)
and correction of imbalances
What is hypercalcemia of malignancy often secondary to? - CORRECT ANSWER Bony metastasis
What is the prognosis associated with hypercalcemia of malignancy? - CORRECT ANSWER Poor
prognosis
What should be checked to assess hypercalcemia? - CORRECT ANSWER Ionized calcium levels
What are the treatments for hypercalcemia of malignancy? - CORRECT ANSWER IV fluids,
calcitonin, bisphosphonates, glucocorticoids
What is hyperviscosity syndrome? - CORRECT ANSWER A rare condition caused by excess serum
proteins or cellular components, leading to hypoperfusion
What are the treatments for hyperviscosity syndrome? - CORRECT ANSWER IV resuscitation,
plasmapheresis, leukopheresis, phlebotomy
What autoimmune disorder mistakenly attacks healthy tissue? - CORRECT ANSWER Lupus
What are common treatments for lupus? - CORRECT ANSWER Supportive care, NSAIDs,
steroids, hydroxychloroquine, methotrexate, other immunosuppressives
What triggers Guillain-Barré syndrome? - CORRECT ANSWER Immune system attacks peripheral
nerves usually after bacterial or viral exposure
