Case study 17
1. Given the diagnosis of acute MI, what other lab results are you going to look at?
CKMB, Troponin I, Myoglobin- which are all cardiac injury markers. ECGs done at an outside hospital or en route, noting the context in which notable ECGs were printed.
2. You find the following laboratory results in the patient’s chart. For each, interpret the result, and evaluate the meaning for C.B. a. Creatinine phosphokinase (CK) levels drawn on admission to the ED and at a 4-hour intervals have been increasing over the time period indicating heart damage or inflammation. CK-MB are high and increasing over the intervals indicating heart damage or heart attack. b. LDL-C:160mg/dl Elevated levels of LDL cholesterol can indicate risk for heart disease, so your LDL-C result is evaluated with respect to the upper limits that are desired for you. According to the National Cholesterol Education Program, if you have no other risk factors, your LDL-C level can be evaluated as follows: her value is High at 160 range c. SaO2 on O2 at 6L/min by nasal cannula: greater than 90%- sats are still low for being on 6Lpm, would like to see patient to 95% or more. d. The value is normal indicating the viscosity of C.B.s blood is good. e. Magnesium is high. Magnesium is not monitored as frequently as some other minerals. It tends to be ordered primarily when a person has an abnormal calcium level and when a person has symptoms that may be due to a magnesium deficiency or excess. Which in can affect the heart. f. As part of a routine medical exam, when you have symptoms such as weakness and/or cardiac arrhythmia, or when an electrolyte imbalance is suspected; at regular intervals when you are taking a medication and/or have a disease or condition, such as high blood pressure (hypertension) or kidney disease, that can affect your potassium level 3. The 12- lead ECG can tell you the location of the infarction. Look at...
