Bio 202 Unit 1 Case Study

Bio 202 - Unit #3 Case Studies:
1- Blood, Heart, and Vessels
1)WHy are lymph nodes enlarged (adenopathy)? How does this fit with his CBC test?
J.T’s lymph nodes are enlarged due to a high count of white blood cell count . Jt has a high white blood cell count because his body is trying to fight off an infection.
2) What is the most likely diagnosis that explains all of J.T’s symptoms and lab results?
J.T. has Acute Myeloid Leukemia, his symptoms are fatigue, shortness of breath, bleeding, bone pain, minor cuts won't heal, and easily bruising. J.T’s bone marrow biopsy results show >90 % of lymphoid cells in the marrow are monotypic/monoclonal B-lymphocytes. This means that the stem cells that produce myeloblasts develop immature abnormal cells,

Normal ST segment should not be elevated and N.K’s shows ST segment elevated in ER.
6) What is the most likely diagnosis for patient # 1, angina or and acute myocardial infarction? Why key evidences led you do that conclusion?
N.K. acute myocardial infarction, because ST segment is elevated and T wave is peaked meaning he is not getting enough oxygen.
7) examine the patient's history and blood lipid results. What do the results of these test, in combination with his BMI tell you about a possible cause of his condition.
N.K. had plaque formation in his coronary artery due to high levels of bad cholesterol, and being overweight caused his condition.
8) what does the presence of a Q-wave on patient #1 ecg one day after admission to the er indicate about the condition of his heart.
A day after admission N.K. ’s EKG shows R wave decreasing meaning AV nodes are not firing, Q wave shows AV nodes not filling ventricles, an ST is more elevated. Meaning N.K. is having a complete obstruction in coronary artery this is called myocardial infarction.
9) what minimally invasive procedure could be used to treat patient # 1’s coronary artery

4) what is the final diagnosis of patient # 2 heart condition name the
(disease)?
Enlarge heart, heart failure hypertrophic cardiomyopathy because the thickened heart muscle and chambers are thick and stiff and don't allow heart to fill. 5) describe how G.L condition caused syncope following exercise?
Exercises increases heart rate and stroke volume so cardiac output is high. But due to the fact that G.L has a hypertrophic cardiomyopathy his cardiac output is low because the lack of heart filling.
6) what is left ventricular hypertrophy? Why would G.L condition cause left ventricular hypertrophy?
Left ventricular hypertrophy is when the heart muscle is thickened the chambers are stiff and thick and this does not allow the heart to fill. 7) what does the inverted T- wave indicate? Why does it appear only when the patient exercises.
T wave indicates repolarization of ventricles. And when exercising the demand of ventricles high but the recovery of the ventricular muscle is not able reach resting state. 8) what two procedures are typically used to treat G.L condition?
Pacemaker, or medications such as ACE inhibitors, beta blockers, and calcium channel blockers.
