Please exchange score sheets with the table nearest yours and then circle the correct answers only as I review them.
#1 Correct answer is B Basophilia should be considered as potential evidence of leukemia or a related disorder until determination of the absolute count (and, if also elevated, further assessment)
# 2 Correct answer is D Mean corpuscular hemoglobin concentration has nothing to do with heavy smoking or smokers erythrocytosis. Hematocrit is always elevated, hemoglobin is sometimes minimally elevated and the white blood cell count is also sometimes elevated in heavy smoking due to inflammation
# 3 Correct Answer is B Water pipe smoking typically involves substantial exposure to nicotine even when used just on one occasion. One daily light cigarette, large cigar or E-cigarette is unlikely to cause elevated cotinine at prevailing industry cutoffs.
# 4 Correct Answer is D Sclerosing cholangitis is a serious complication of inflammatory bowel disease presenting with this cholestatic pattern of abnormal liver tests. None of the others are more prevalent in ulcerative colitis and, of these other three, only chronic hepatitis B is more than rarely encountered with this pattern of test results.
# 5 Correct Answer is C Iron deficiency anemia has a low MCV. Alcohol abuse, pernicious anemia and myelodysplastic syndrome are often associated with an elevated MCV.
# 6 Correct Answer is C Banded neutrophiles are common in healthy people and persons with various kinds of transient infections Elevated MPV is associated with excess mortality due to potentially significant causes Elevated RDW has increased mortality in its own right Nucleated red blood cells are an absolute RED FLAG for underlying hematological disease
# 7 Correct Answer is B Eosinophilia is common in allergy-related disorders such as asthma and eczema. The others are not significantly more prevalent in either of these disorders.
# 8 Correct Answer is D Chewing coca leaves and drinking mate de coca are often associated with true positive cocaine tests. Cocaine is sometimes used as an anesthetic for facial surgery and a positive test would have to be considered true positive pending further investigation with the surgeon. Handling money in a Miami bank makes no sense as an argument for a true-positive test! Therefore, given the low prevalence of true-positives in the general population, this scenario is most apt to represent a false-positive.
# 9 Correct Answer is B Hepatitis D requires HBV to replicate. None of the others are associated with an increased risk of hepatitis D.
# 10 Correct Answer is A Apolipoprotein E tests are mainly used for detecting genetic predisposition to Alzheimer dementia…and any form of dementia is rather rare in a 31 year old genius! Apolipoproteins B and A-1, as well as non-HDL- C cholesterol are all used in the context of hyperlipidemia.
Any table that got the first 9 questions correct but the last one wrong is clever, because someone obviously noticed that all of the first 9 correct responses were GREEN But then they got tripped up because I used BROWN for the correct answer to question # 10!
Do We Have any Tie Scores for 1 ST, 2 ND or 3 RD Place? If so, now we go to the tie-breaking (and jaw-dropping) questions!
Tie-breaker #1 66 year old female had CBC with hemoglobin 9.1, HCT 28% and MCV 69. Her ferritin test was 20 Which of the following endoscopic examinations is she most likely to have next? A.Colposcopy B.Cystoscopy C.Colonoscopy D.Esophagogastroscopy E.Bronchoscopy F.Transthoracic anoscopy
Correct answer is C Anyone who answered F should be stripped of their FALU!
Tie-breaker # 2 Which of the following tests is LEAST LIKELY to be elevated/positive in a Type 2 diabetic due to the diabetes or its prevalent comorbidities? A. eGFR B. Creatinine C. Serum Albumin D. Hepatitis C antibody test E. GGT F. Cystatin C
Correct Answer is C Elevated albumin is due mainly to transient dehydration and has nothing to do with diabetes or its prevalent comorbidities. Elevated eGFR often occurs due to kidney hyperfiltration prior to onset of diabetic nephropathy. All of the others are also clearly related to diabetes or its comorbidities
Tie-breaker # 3 In a 68, 335 lb longshoreman and competitive weightlifter, which abnormal lab finding on a routine screening blood profile is LEAST LIKELY to have underwriting implications? A.BUN of 3 (normal 5-25) B.Cholesterol of 116 (normal 160-200) C.Bilirubin of 0.1 (normal 0.3-1.1) D.AST of 72 (normal 0-35) E.HDL-C of 19 (normal 45-80) F.GGT of 110 (normal 0-65)
Correct answer is D Modestly elevated AST is not uncommon in this setting and is most likely due to weightlifting as well as the heavy labor involved in his day job. GGT, unlike AST, is not elevated by exercise or muscle use Low BUN is a red flag for advanced liver disease, etc. Very low levels of cholesterol and HDL-C suggest anabolic steroid abuse in a weightlifter Very low total bilirubin is an independent marker for excess mortality in all settings
Tie-breaker # 4 Which of these scenarios is MOST LIKELY to be associated with significant extra mortality A. Isolated ALT elevation in a slender woman with polycystic ovary syndrome B. Isolated GGT elevation in an epileptic on 2 drugs C. Isolated alkaline phosphatase elevation in a 22 year old male who just returned on crutches from a ski resort D. Isolated serum globulin elevation in a female NASCAR driver E. Isolated total bilirubin 2.5 times normal in a 48 year old washed up pro golfer F. Isolated creatinine elevation in Packer defensive lineman Johnny Jolly
Correct Answer is D NACAR driving has no correlation with elevated globulin and elevated globulin is presumed to be due to disease and must be further evaluated. All of the others can potentially be explained by the circumstances in which they have occurred and are unlikely to be associated with significant mortality in these contexts
Tie-Breaker # 5 Which of these medications is NOT a potentially abusable drug? A.Pregabalin (Lyrica) B.Chlordiazepoxide (Librium) C.Aripiprazole (Abilify) D.Buprenorphine (Buprenex) E.Methylphenidate (Ritalin)
Correct answer is C Aripiprazole (Abilify) is an antipsychotic and no one would want to take it for fun!
