Bobby. Blood pressure: 120/70 Cardiac output 5.0 Hemoglobin: 5.0 Urine output 5.0
Ken. Blood pressure: 130/80 Cardiac output 5.5 Hemoglobin: 5.5 Urine output 5.5
Penny. Blood pressure: 110/70 Cardiac output 4.9 Hemoglobin: 4.9 Urine output 4.9
Hanna. Blood pressure: 90/65 Cardiac output 3.0 Hemoglobin: 3.0 Urine output 3.0
Out of Bobby, Ken, Penny, and Hanna who is most likely to be suffering from a heart attack caused by atherosclerosis at this point in time. Which test results led you to the selection and explain why these results indicate that the patient is suffering from the disease specified. Hm where did you get this case vignette from?
i can only hazard a guess, and i think that it is Hanna who is most likely to be suffering from the heart attack. this is because her blood pressure has dipped to low levels..90/65 is considered low.
In addition, her cardiac output is 3. Cardiac output is actually a mathematical entity, calculated from stroke volume multiplied by heart rate, a normal value is actually 4.9 ml/min. A heart attack would render the heart muscle ischemic and nonfunctional, thus the heart would lose both stroke volume, which is the volume of blood ejected at the end of every systole or contraction. Thus consequently, the cardiac output would diminsh.
Urine output is decreased also, an explanation would be that in a heart attack, there is less blood entering the systemic circulation and thus the kidneys, thus the renal output would decrease because of loss of function of the kidneys due to decreased glomerular filtration rate(GFR). there is thus less filtrate.
Hemoglobin is naturally low due to the loss of blood in a heart attack, for example a rupture of the heart muscle resulting in hemorrhage can occur.
Hope this helps. :D
btw, if you have a correct answer, could you mail me or contact me? i would like to know if i am correct, thanx so much!! As confused as a hungry baby in a topless bar |
