About this Exam

Prepare with the Arab Board Clinical Pathology Part 1 Practice Questions - Arab Board Clinical Pathology Part 1 Written Examination (ABHS) Exam practice quiz. This question bank includes 100 questions covering year-old, blood, normal, mmol, and presents. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.

Sample Questions

Question 1
A 35-year-old man is brought to the emergency department unconscious. Arterial blood gas shows pH 7.12, pCO2 28 mmHg, HCO3- 9 mmol/L, Na+ 140 mmol/L, K+ 5.1 mmol/L, and Cl- 102 mmol/L. Measured serum osmolality is 325 mOsm/kg, blood glucose is 90 mg/dL (5.0 mmol/L), and blood urea nitrogen is 14 mg/dL (5.0 mmol/L). Urinalysis demonstrates envelope-shaped calcium oxalate crystals. What is the calculated osmolar gap and the most likely etiology?
Osmolar gap 32 mOsm/kg; Ethylene glycol ingestion
Osmolar gap 12 mOsm/kg; Diabetic ketoacidosis
Osmolar gap 5 mOsm/kg; Salicylate toxicity
Osmolar gap 32 mOsm/kg; Methanol ingestion
Question 2
A 68-year-old woman with chronic kidney disease (stage 4) presents with acute chest discomfort. Initial high-sensitivity cardiac troponin T (hs-cTnT) is 38 ng/L (upper reference limit: 14 ng/L). Which laboratory finding best distinguishes an acute non-ST elevation myocardial infarction (NSTEMI) from chronic baseline elevation in this patient?
Elevated baseline serum creatinine
A significant rise and/or fall in hs-cTnT on serial testing at 1 to 3 hours
A concurrent elevation in serum total creatine kinase (CK)
A single troponin value greater than the 99th percentile URL
Question 3
A routine serum chemistry panel on an asymptomatic 58-year-old man with essential thrombocythemia reveals a serum potassium of 6.6 mmol/L (reference: 3.5-5.0 mmol/L). A simultaneous ECG shows normal sinus rhythm with no peaked T waves or PR prolongation. His platelet count is 980 x 10^9/L. What is the most appropriate laboratory action to establish the true circulating potassium concentration?
Repeat the measurement using heparinized plasma maintained at room temperature
Repeat the measurement on serum after 4 hours of clot retraction at 4°C
Immediately administer intravenous calcium gluconate and insulin-dextrose
Perform arterial blood gas analysis using an EDTA tube
Question 4
A 24-year-old woman with type 1 diabetes presents with severe nausea, persistent vomiting, and abdominal pain. Laboratory results are: Na+ 136 mmol/L, K+ 4.8 mmol/L, Cl- 88 mmol/L, HCO3- 16 mmol/L, and arterial blood pH 7.32. Her calculated anion gap is 32 mmol/L. What does calculation of the delta ratio (delta AG / delta HCO3-) indicate regarding her acid-base status?
Pure high anion gap metabolic acidosis without any secondary metabolic disorder
Mixed high anion gap metabolic acidosis and normal anion gap metabolic acidosis
Mixed high anion gap metabolic acidosis and concurrent metabolic alkalosis
Pure respiratory acidosis with appropriate renal compensation
Question 5
A 45-year-old man with poorly controlled type 2 diabetes and chronic autoimmune hemolytic anemia (hemoglobin 8.8 g/dL, reticulocyte count 8.2%) has home capillary glucose readings consistently averaging 220 mg/dL (12.2 mmol/L). However, his laboratory HbA1c is reported as 5.2% (reference: <5.7%). What is the most appropriate test to monitor his glycemic control?
Serum fructosamine assay
Oral glucose tolerance test (OGTT)
Urine microalbumin-to-creatinine ratio
Fasting plasma C-peptide measurement
