Hypertension (high blood pressure) will have its most immediate effect on Preload Contractility Afterload None of these 2. Mature, circulating RBC’s lack endoplasmic reticulum. Without these structures RBC’s are completely unable to synthesize any ATP Protein All of the above Hemoglobin 3. Which of the following would indicate that a client with chronic bronchitis has developed secondary polycythemia vera: Increased hematocrit Abnormal arterial blood gas x Cyanosis Peripheral edema Stroke volume is 4. What is Stroke volume The amount of blood the heart ejects per minute The amount of blood the heart ejects per beat Equal to the total blood volume of approximately 5 L 5. Glomerulonephritis is associated with a(n) Elevated BUN/creat levels due to increase GFR Decreased BUN/creat levels due to decreased GFR Decreased bun/creat levels due to increased GFR Elevated bun/creat level due to decreased GFR 6. Which of the following would not typically be observed in a client with asthma Wheezing Chest tightness SOB Productive cough 7. A prolonged episode of tachycardia will result in Increased ejection fraction No change in stroke volume Increased stroke volume Decreased stroke volume 8. Tubular reabsorption and tubular secretion differ in that Secretion adds material to the filtrate, reabsorption removed material from the filtrate Secretion occurs via passive transport, reabsorption occurs via active transport Secretion adds material to the blood; reabsorption removes material from the blood Reabsorption tends to increase urine volume, secretion tends to decrease urine volume 9. After erythrocytes have completed their lifespan , they are removed by macrophages located mainly in the Yellow bone marrow Appendix Spleen Liver x 10. Alveolar hyperinflation occurs in asthma and chronic bronchitis as the result of Thorax expansion Increased rate of pulmonary capillary perfusion Sustained bronchodilation Decreased ability to exhale 11. The primary site of damage in the nephron due to ischemic conditions is the Bowmans capsule Loop of henle Distal convoluted tubule Proximal convoluted tubule 12. The movement of blood into and out of the capillary beds of the lungs to the body tissues and cells describes the process of Metabolism Respiration Perfusion Ventilation 13. A 5-year-old female presents with frequent urinary tract infections, imagine studies indicate a retrograde flow of urine from the urinary bladder into the ureters. This is indicative of Hypospadias Vesicoureteral reflux Renal agenesis x Polycystic kidney disease 14. A 30-year-old client who had a gastrectomy procedure 1 year ago is most at risk for the development of Iron-deficiency anemia Aplastic anemia Hemolytic anemia Pernicious anemia 15. A deficiency of intrinsic factor (IF) will most likely result in Pernicious anemia Iron-deficiency anemia x Folate-deficiency anemia Aplastic anemia 16. During ventricular systole A and b Venous blood from the systemic circulation enters the right atrium The mitral and tricuspid valves are closed The mitral and tricuspid valves are open 17. A deficiency of transferrin is most likely to result in Aplastic anemia Iron-deficiency anemia Hemolytic anemia Pernicious anemia 18. The primary source of erythropoietin is the Spleen Kidney Liver Bone marrow 19. Which of the following is not a condition associated with renal failure Hypernatremia Hyperphosphatemia Hypokalemia Hypocalcemia 20. A 25-year-old female presents with frequent complete calculi blockage of one ureter. This is referred to as Postrenal disease Hypercalcemia Intrarenal Prenatal disease 21. Contractility of cardia muscle is directly dependent on the level of Calcium Chloride Sodium Potassium x 22. Appropriate management of progressive renal failure typically includes All of the above Potassium supplementation High protein diet Erythropoietin administration 23. In addition to oxygen, hemoglobin also carries nitric oxide (NO) No is important for Preventing free radical damage to RBC membranes Promoting vasodilation Preventing conversion of Fe +2 to fe+3 Increasing oxygen binding affinity of Hb x 24. Which equation correctly represents cardiac output (CO) CO = heart rate x pulse rate CO = heart rate x stroke volume CO = heart rate x blood pressure x CO = blood pressure x stroke volume 25. Which of the following statements correctly describes the flow of blood between the heart and lungs Oxygenated blood is transported from the lungs to the heart via the pulmonary veins Deoxygenated blood is transported from the left ventricle to the lungs via the pulmonary arteries The pulmonary arteries carry oxygenated blood from the lungs to the heart Oxygenated blood is transported from the lungs to the right atrium of the heart
