# Practical Exam - Physiology 1 - Module 4 - 2024 - V3-3 ## Student's Name: ## Group: ## Date: ## Grade (completed by teacher): **1. The protein component of the membrane consists of:** - Ion channels - Cholesterol - Phospholipids - Glycolipids **2. The movement of water across the cell membrane occurs by the following:** - Osmosis - Active transport - A process which does not require energy - A process which requires energy **3. Female patient of 50 years old presents with hyperventilation. ABG: pCO2=16 mmHg (decreased), HCO3=26 mEql/l (normal), pH=7.5 (increased). Acid-base status?** - Respiratory alkalosis - Respiratory acidosis - Primary change is the lung - Primary change is the kidney **4. The ventral respiratory group:** - Mainly causes inspiration - Regulates the basic rhythm of respiration - Can cause either expiration or inspiration - Is active during eupnea **5. About the gas-blood barrier it is true that:** - Is only 0.1 µm wide - Gases such as oxygen have to diffuse across the gas-blood barrier - Neutrophils can move between endothelial cells - Oxygen diffuses by a process called extravasation **6. Choose the right answers regarding the alveoli:** - Are located at the end of terminal bronchioles and alveolar ducts - Are the secondary sites for gas exchange - Are the functional units of the lung where gas exchange takes place - Are located at the beginning of terminal bronchioles and alveolar ducts **7. Choose the correct answer:** - Haptoglobin: negative acute phase protein, binds free hemoglobin - Ceruloplasmin: positive acute phase, binds serum copper - Transferrin: negative acute phase protein, binds serum iron - C-reactive protein: negative acute phase protein **8. 70-year-old male with known chronic pulmonary disease. ABG: O2 sat = 90% (decreased), PCO2= 55 mmHg (increased), HCO3=30 mEql/L (increased), pH=7.30 (decreased) Acid-base status?** - Respiratory alkalosis - Respiratory acidosis - Metabolic alkalosis - Metabolic acidosis **9. Choose the false statement about monocytes:** - Are the smaller cells in the peripheral blood - Are the largest leucocytes - Spend 1-3 days in blood - Represent ~ 20%-25% of the blood population of leucocytes **10. The predictive vital capacity:** - Can be calculated using an equation - It is calculated depending on height and age - It is not dependent on other factors except height and age - It is the same formula for both male and females **11. Choose the correct answer/answers:** - The inspiratory capacity = tidal volume + inspiratory reserve volume - The inspiratory capacity=residual volume+ inspiratory reserve volume - The functional residual capacity = tidal volume + inspiratory reserve volume - The expiratory capacity = residual volume + inspiratory reserve volume **12. Red blood cells in a hypertonic solution:** - Will swell - Will shrink - No modification occur - Will release hemoglobin **13. Albumin:** - Is a positive acute phase protein - Nonspecific binder of substances - Mantains colloid osmotic pressure - Mantains hydrostatic pressure **14. Male patient of 49 years old presents with cough and dyspnea, cyanosis is shown in the perioral area. ABG: pCO2=49 mmHg (increased), HCO3=26 mEql/l (normal), pH=7.3 (decreased). Acid-base status?** - Respiratory alkalosis - Respiratory acidosis - Primary change occurs in the lung - Primary change occurs in the kidney **15. Regarding the Tiffneau index the following are true:** - Represents the proportion of a persons inspiratory capacity - Represents the proportion of a persons vital capacity - it is also called the bronchial permeability index - Represent the air a person is able to expire in the first minute **16. A 45-year-old patient presents to the Emergency Department. The CBC results are: RBC 1.96x105/µl (Ν: 4-6x10°/µl), WBC 9x10³/µl (Ν: 3.6-10x10³/µl), Hgb 5.10 g/dl (N: 12-16 g/dl), MCV 68 fl (N: 78-95 fl), Hct 17.20% (N: 39-54%), PLT 352x10³/µl (Ν: 150-450x101/µl). Which test can help you to establish a diagnostic from the following?** - Leukocyte formula - Acute-phase protein concentration - Reticulocyte count - Prick tests **17. The blood group O contains:** - Anti-B antibodies - Type A antigen - Type B antigen - Anti-A antibodies **18. The platelet phase of hemostasis consist of:** - The formation of the fibrin network - The formation of white platelet thrombus - The reflex spasm of the vessel - Adhesion of platelets and their subsequent aggregation **19. Eosinophilia is present in:** - Parasitic infection - Viral infection - Tissue necrosis - Hypersensitivity **20. Choose the correct answer regarding the erythrocyte sedimentation rate (ESR):** - In polycythemia, the value of the ESR is decreased based on increased HCT level - The anizo/poikilocytosis does not modify the value of the ESR - The rouleaux structures form due to the electronegativity of the RBCs surface - An ESR value >100 mm/h is associated with neoplasia **21. Choose the lab tests that can help you to investigate an inflammatory syndrome based on the innate immune system:** - Lymphogram - Quantitative determination of IgE in serum - C-reactive protein - Fibrinogen **22. Poikilocytosis is defined as:** - Uniform red blood cell population - Variation in the shape of the red cells - The presence of target cells and schistocytes - Variation in the size of red cells **23. The blood group B contains:** - Anti-A antibodies - Type AB antigen - Type O antigen - No antibodies in the serum **24. Choose the correct answer about the immunophenotyping:** - To determine the lymphogram, the antibodies bind to the RBCs - Analysis of the expression of different cell surface or intracellular molecules- CD - Can be used to quantify only the neutrophils population - Offers information about the lineage, maturation stage, or activation status of a cell **25. Considering CBC results, what is the patient's pathology?** - Hypochromic microcytic anemia - Neutropenia can explain leukocytosis - The depression of the RBC is correlated with the HCT value - Take into consideration PLT value, we expect PCT to be increased The table in the image contains information about the hemogram. The table is too long to be converted into markdown.
