Patient Abnormal Values
On 09/16 patient shows signs of hypoglycemia due to insulin overdose. -
assuming patient is being treated for type 2 diabetes with insulin
On all days the TP and albumin are decreased while AST and Alt are elevated w/ AST being more than double on the first three days then being only slight more increased than the ALT on the 19th. Total bilirubin is also elevated which indicative of liver disease/ disorder.
On all days the BUN/Creat/ K (normal on day 4) levels are all elevated which is most likely due to patient being diabetic causing pre-renal azotemia and hyperkalemia. On 09/17 GFR was estimated at 15 which for African Americans 15 – 21 is indicative of stage 3 chronic kidney disease.
On all days calcium levels are decreased which is indicative of low protein blood levels, especially albumin, resulting from liver disease and /or malnutrition that may result from alcoholism

Patient Abnormal Values
On 09/16 Patient had Troponin test – 0.21 which is suggestive of
myocardial damage, and ETOH– negative, CPK 119 in normal ranges
On 09/17 patient had Troponin test 0.37.
On 09/18 patient had Mg tested 2.8 (elevated- indicative of kidney failure and hypothyroidism) TSH 16.40 (elevated- hypothyroidism) Troponin .023, NT ProBNP 7869 (elevated-patient has history of CHF/Afib and levels may also be increased due to kidney disease,GFR indicating stage 3 renal failure. Other factors that elevate ProBNP are female sex, liver cirrhosis, and sepsis)
On 09/19 patient had RA Factor 1:64 which is indicative of advanced Rheumatoid arthritis. While the RA Factor is closely associated with RA other disease can also cause elevated results such as chronic infections and cirrhosis.

Patient Abnormal Values
Assuming that patient is on Coumadin/Warfarin because of CHF/ Afib. It
would be the cause of the excessive anticoagulation seen on 09/16/14. Patient had a PT of 124.5 seconds and INR of 10.3. Patient has risk factors that could have possibly lead to the excess anti coagulation, age over 70, leg wound, CHF, and Afib. Patient most likely was taken off of anticoagulant medication and and given Vitamin K to bring PT/INR levels back into normal ranges.
Specific patient characteristics have been identified that are associated with increased risk of bleeding:
including advanced age (> 65 yrs); history of stroke, gastrointestinal bleeding or heart disease concurrent aspirin therapy atrial fibrillation renal insufficiency anemia long duration of anticoagulant therapy hypertension.

Patient Abnormal Values
The CBC results are post transfusion WBC values are
not included because they are in the normal ranges. Between 09/16 and 9/17 the patient received 350 mL of packed RBC four times and the patient’s RBC, Hgb ,Hct, MCH, and MCHC are still below the normal value which is indicative of anemia and kidney failure. The decreased MCH and MCHC are indicative of hypochromia and the elevated RDW is due to the mixed population of small and large RBC possible from receiving blood products.

Urine sample sent to Microbiology department for microbial identification. Plated on Blood agar and Macconkey Plate. Final results received on 09/19/14. Organism identified as E. coli >100,000 colonies * ESBL
**Extended spectrum beta-lactamase. ESBLs are enzymes capable of hydrolysing penicillins, broad-spectrum cephalosporins and monobactams. Clinical outcomes data indicate that ESBLs are clinically significant and, when detected, indicate the need for the use of appropriate antibacterial agents.**
Patient Abnormal Values
Microbiology Laboratory Results
09/16/14 13:33 Blood Culture – growth after 24 hours resulted on 09/17/14, organisms identified as MRSA, Staphylococcus epidermis, and Enterococcus fecium. No growth after five days.
09/16/14 17:57 Nasal swab collected. Resulted at 20:00 positive for MRSA
09/17/14 14:31 Wound swab from left leg collected for culture. Gram stain showed few gram positive cocci in pairs and clusters with moderate WBC and few RBC. Resulted on 09/18/14 at 11:55 organism identified as MRSA heavy growth.
Patient Abnormal Values
Treatment
Dextrose 50%- 25g IV – hypoglycemia
Rocephin 1g –IV- bacterial infection, septicemia due to Staphylococcus aureus
Vitamin K (phytonadione) 10mg/ p.o. – reverse excessive anticoagulation
Thawed plasma <24 hrs.- used to treat bleeding due to acquired multiple factor deficiency such as large volume bleeding or DIC. ** patient on anticoagulant therapy with possible bleeding
Packed RBC- insufficient tissue oxygen delivery due to active bleeding/ symptomatic anemia
Patient Treatment
Prognosis
Diagnosis
With proper treatment and ensuring that patient is
not only being administer diabetic medication, but also eating, patient should not experience diabetic hypoglycemia.
Patient needs to have regular laboratory test done to prevent another episode of excessive anticoagulation, however the prognosis for this condition is not good due to the many risk factors this patient has that contribute to the problem.
Overall outlook for the patient is poor due to patient decline in health, renal failure, and liver disorder.
