ANSWERS/COMPLETE LATEST 2023

GRADED A

Which of the following condition is the most common cause of increase anion gap? A. Metabolic alkalosis B. Metabolic acidosis Respiratory acidosis Respiratory alkalosis ✔✔B. Metabolic acidosis High anion gap metabolic acidosis is caused generally by the body producing too much acid or not producing enough bicarbonate. This is often due to an increase in lactic acid or ketoacids, or it may be a sign of kidney failure. More rarely, high anion gap metabolic acidosis may be caused by ingesting methanol or overdosing on aspirin. Which of the following enzymes has the longest elevation after Myocardial Infarction (MI)? CK-MB Myoglobin Troponin AOTA ✔✔C. Troponin

Ace ASCP Questions and Answers

Rated A

Glucosuria Normal ✔✔A. Presence X-Ray medium Feedback Xray medium/Radiographic dye can cause erroneous results in urine specific gravity measurement. A patient with walking pneumonia is being treated with penicillin. State one possible condition why the patient is not recovering: The organism produces beta lactamase The organism has no cell wall The organism has capsule The organism produces an enzyme that neutralizes the antibiotic ✔✔B. The organism has no cell wall. Feedback Pneumonia caused by Mycoplasma pneumoniae is routinely treated with antibiotics, although the disease is usually self-limiting. The disease is treated with macrolide, tetracycline, or fluoroquinolone classes of antibiotics. All mycoplasmas lack a cell wall and, therefore, all are inherently resistant to beta-lactam antibiotics (e.g., penicillin).

What is the coefficient of variation if the mean is 90 and the standard deviation is 5.48?

30 ✔✔B. 6. Feedback: CV= SD/meanX100, (5.48/90)X100= 6.09. Blood smear below denotes Hairy Cell Leukemia (HCL), which of the following test is used to identify this type of leukemia? Image. 1 Myeloperoxidase Tartrate-resistant acid phosphatase Tartrate-resistant alkaline phosphatase

D>c>E>C>e D>C>E>c>e D>c>E>e>C C>D>c>E>e ✔✔A. D>c>E>C>e Feedback Most immunogenic D > c > E > C > e least immunogenic. Most common error in Polymerase Chain Reaction (PCR) is NUCLEIC ACID CONTAMINATION. A True (Correct Answer) B False ✔✔A. True What disease is associated with the possession of HLA-B27? Ankylosing spondylitis Hashimoto's Disease Goodpasture's syndrome

SLE ✔✔A. Ankylosing spondylitis Feedback: Ankylosing spondylitis belongs to a group of arthritis conditions that tend to cause chronic inflammation of the spine (spondyloarthropathies). The HLA-B27 gene can be detected in the blood of most patients with ankylosing spondylitis. Burr cells are seen in the peripheral blood smear, this is indicative of? (Fig. 2) Uremia (Kidney Disease) Anemia Leukemia Liver Disease ✔✔A. Uremia (kidney Disease) Feedback: The above shown picture illustrates Burr cells, these cells are indicative of Uremia (kidney disease) Anti IgG (-); C3d (+): What should the MLS do?

NOTA ✔✔C. 3 days CIN (Cefsulodin, Irgasan, Novobiocin) Agar is a recommended culture medium for the recovery of: Rhodococcus equi Cardiobacterium hominis Brucella suis Yersinia enterocolitica ✔✔D. Yersinia enterocolitica Feedback: CIN Agar is recommended for use in the selective and differential isolation of Yersinia and Aeromonas species from clinical specimens, environmental samples, and food sources. Yersinia enterocolitica will exhibit bull's eye appearance on the said agar. What is the formula for sensitivity? TP/(TP+FN)x TP/(TP+FP)x

(TP+FN)/TPx (TP+FP)/TNx100 ✔✔A. TP/(TP+FN)x CThe anemias of the qualitative hemoglobinopathies, such as sickle cell anemia, are morphologically classified as: Microcytic, hypochromic Macrocytic, normochromic Normocytic, normochromic NOTA ✔✔C. Normocytic, normochromic According to AABB standards, Fresh Frozen Plasma (FFP) must be infused within what period of time following thawing? 24 hrs 36 hrs

Bartonella henselae Leptospira interrogans ✔✔A. Pasteurella multocida Feedback Pasteurella species are commonly isolated pathogens in most animal bites, especially in dog- and cat-related injuries. These injuries can be aggressive, with skin manifestations typically appearing within 24 hours following a bite. These wounds can exhibit a rapidly progressive soft-tissue inflammation that may resemble group A β-hemolytic Streptococcus pyogenes infections. What is the sugar fermented by Staphylococcus aureus? Mannitol Sucrose Glucose Maltose ✔✔A. Mannitol Mannitol salt agar is a commonly used growth medium in microbiology. It encourages the growth of a group of certain bacteria while inhibiting the growth of others. It contains a high

concentration (7.5%-10%) of salt (NaCl), making it selective for gram positive bacteria Staphylococci (and Micrococcaceae) since this level of NaCl is inhibitory to most other bacteria. It is also a differential medium for mannitol fermentors, containing mannitol and the indicator phenol red. Staphylococcus aureus produce yellow colonies with yellow zones, whereas other Staphylococci produce small pink or red colonies with no colour change to the medium. If an organism can ferment mannitol, an acidic byproduct is formed that will cause the phenol red in the agar to turn yellow. Identify the organism: Fig. 3 Blastomyces dermatitidis Malasezia furfur Alternaria Candida albicans ✔✔A. Blastomyces dermatitidis Feedback The above image show broad base budding. What is the first step in agglutination? Sensitization

A newborn infant has a WBC count of 37,000/ul with the differential count revealing the presence of 50 nRBCs per 100 WBCs. What is the corrected WBC count? 15,000/ul 24,700/ul 27,300/ul 12,500/ul ✔✔B. 24,700/ul Feedback Corrected WBC count= Uncorrected WBC count x100/nRBCs+100: Thus, (37,000ulx100/50+100= 24,700ul) Gram positive bacilli; non-motile; non-hemolytic; catalase positive; spore forming: B. anthracis B. cereus N. meningitidis N. lactamica ✔✔B. B. anthracis

Feedback Important distinguishing characteristics between B. anthracis and B. cereus is motility, B. anthracis is non motile while B. cereus is motile. Hair perforation test/Hair baiting test is for identification of which two fungi? Aspergillus niger and A. japonicus Tinea pedis and T. corporis Trichophyton mentagrophyte and T. rubrum C. albicans and C. tropicalis ✔✔C.

Acute glomerulonephritis Renal tubular failure Addison's disease Diabetes insipidus ✔✔D. Diabetes insipidus Feedback Low specific gravity (SG) (1.001-1.003) may indicate the presence of diabetes insipidus, a disease caused by impaired functioning of antidiuretic hormone (ADH). Low SG also may occur in patients with glomerulonephritis, pyelonephritis, and other renal abnormalities. Primidone monitoring: suspected to have primidone overdose, but the serum concentration is within the normal range, what should the MLS do next?
