4.Red blood cells last about 120 days. Your body needs to have a constant supply to replace them.ANS: 4Red blood cells have a life span of about 120 days. Abnormal red blood cells have a shorter lifespan and are lysed and extracted from the circulation. The nurse should explain that since redblood cells live 120 days, the body needs a constant supply. The transfusion will provide thecells until the body makes new ones.PTS: 1 DIF: Apply REF: Erythrocytes2.The nurse is reviewing a clients white blood cell count. Which of the following would not beaffected by the presence of an infection?1.Basophils2.Eosinophils3.Lymphocytes4.NeutrophilsANS: 3Basophils, eosinophils, and neutrophils are considered granulocytes which are present inincreased amounts in the presence of an infection. Lymphocytes are common in the lymphaticsystem and work with acquired immunity.PTS:1DIF:AnalyzeREF:White Blood Cells3.A client is diagnosed with a parasitic infection. The nurse realizes that which of the followingwhite blood cell counts will be elevated?1.Basophils2.Eosinophils3.Lymphocytes
4.NeutrophilsANS: 2Eosinophils are classically associated with infections from parasites. Eosinophils are also moreinvolved in the reactions to allergies. Basophils are central to the inflammatory process andneutrophils respond to bacterial infections. Lymphocytes are cells that work in acquiredimmunity.PTS:1DIF:AnalyzeREF:White Blood Cells4.A client is diagnosed with a low red blood cell count. Which of the following should the nurseassess in this client?1.Urine output2.Bowel sounds3.Respirations4.ConsciousnessANS: 3The function of the erythrocyte or red blood cell is to transport oxygen from the lungs to the cellsof the body. With a low red blood cell count, the nurse should assess the clients respiratorystatus. The urine output, bowel sounds, and consciousness may or may not be affected by thedecrease in red blood cells.PTS: 1 DIF: Apply REF: Erythrocytes5.A client is prescribed a vitamin B-12 injection every month. Which of the following should thenurse explain to the client as the purpose of this medication?1.It is needed to make new red blood cells.2.It makes the red blood cells more flexible.3.It makes the red blood cells hold more oxygen.4.It makes the red blood cells hold their shape.
ANS: 1Vitamin B-12 is necessary to make erythrocytes and help make thymine, which is a precursor tothe red blood cell. The erythrocyte cytoskeleton makes the red blood cell more flexible.Cholesterol helps the red blood cells hold their shape. There is nothing physiologically that willmake a red blood cell hold more oxygen.PTS: 1 DIF: Apply REF: Erythrocytes6.During the assessment of a client, the nurse identifies pinpoint hemorrhages under the skin thatare dark red and less than 2 mm in size. How should the nurse document this finding?
