A

Iron is mostly stored in hemoglobin of red blood cells

If the second child is Rh positive and she did not take a RhoGAM shot after her first child, There is a chance the second child will develop erythroblastosis fetalis and die before birth

109
Q

A total white blood cell count and a differential white blood cell count has been ordered for Mrs. Johnson. What information is obtained from the differential count that the total count does not provide?

111
Q

A patient complains of no energy, a chronic sore throat, a low-grade fever, and is tired and achy. His doctor notes and enlarge spleen upon examination. What diagnosis would you expect and what definitive test would you request?

A

Diagnosis of possible infectious mononucleosis test would be differential white blood cell count

112
Q

A man of Mediterranean ancestry goes to his doctor with the following symptoms. He is very tired all the time. He has difficulty catching his breath even after mild exercise. His doctor orders the following tests, CBC, hematocrit, differential white blood cell count, and hemoglobin electrophoresis. The test shows immature erythrocytes, fragile erythrocyte, and less than 2 million red blood cells per cubic millimeter. What would be a tentative diagnosis and suggested treatment?

A

Thalassemia; treatment is blood transfusion and chelation therapy to remove excess of iron accumulate from transfusion

113
Q

A 68-year-old male is admitted to the hospital for emphysema. He is hypoxic and his lab test revealed low oxygen levels. His hematocrit is 65%. The physician has told him that he has a type of polycythemia in which he has an increased number of erythrocytes circulating in his bloodstream. The patient tells the nurse that he does not understand what that means. How was the nurse explain this in terms of the patient could understand?

A

Because you have decreased oxygen levels in your blood, your body has responded by producing more red blood cells, called polycythemia. The low oxygen level causes your kidneys to produce a hormone called erythropoietin to stimulate the production of more red blood cells

114
Q

An elderly patient tells the nurse that she has been very tired lately and has difficulty walking to her mailbox without getting very short of breath. The nurse notes the mucous membranes are pale. The patient states that since her husband died three months ago, she has not been eating well. The physician confirms that she has iron deficiency anemia. How are the patient’s clinical manifestations an iron deficiency anemia related?

A

Without iron, the red bone marrow cannot manufacture sufficient hemoglobin. The clinical manifestations are attributed to the reduction in oxygen available to tissues. Anemic individuals are fatigued, often pale, short of breath, and cold

115
Q

A 17-year-old black male is admitted to the hospital in sickle cell crisis. Pain management is a top priority for patient in sickle cell crisis. Explain why.

A

The altered sickle shaped sells makes the blood more viscous in the normal circulation is impaired. The oxygen deprived tissues are forced to switch to anaerobic metabolism, producing lactic acid which causes severe pain and swelling

116
Q

A 52-year-old woman was diagnosed with leukemia and has been receiving chemotherapy as an outpatient. She tells the RN that she hasn’t been feeling well. The patient skin is warm to the touch and she has a low-grade fever of 100.2°F. The neutrophil blood count is less than 1000. The nurse is concerned about the possibility of infection because of the neutropenia and low-grade fever. Explain why.

A

A low-grade fever in someone with neutropenia is a major concern for survival because of the neutrophils raw in phagocytosis. The patient has a decreased ability to fight off infection and can’t respond by quickly developing more white blood cells like normal
