INTRODUCTION
This assessment consists of 100 original practice questions designed for the Indiana Medical Laboratory
Technician Examination. The questions are based on publicly available examination objectives and professional
standards as outlined by the ASCP Board of Certification . This assessment emphasizes knowledge, application,
analysis, critical thinking, and professional judgment. These are original practice questions and are not actual,
leaked, recalled, secure, or live examination questions.
Question 1
A Medical Laboratory Technician (MLT) is performing a venipuncture on an outpatient. The patient states they
have a history of fainting during blood draws. What is the most appropriate action for the technician to take?
,A. Proceed with the draw, but reassure the patient it will be quick.
B. Ask the patient to lie down for the procedure and have ammonia inhalants available.
C. Instruct the patient to look away and take deep breaths during the draw.
D. Request that another, more experienced technician perform the draw.
🟢 Correct Answer: B. Ask the patient to lie down for the procedure and have ammonia inhalants available.
🔴 RATIONALE: Patient safety is the priority. A known history of syncope (fainting) requires a proactive
approach to prevent injury. Having the patient lie down reduces the risk of injury from a fall, and having
ammonia inhalants readily available is a standard precaution for treating syncopal episodes . While reassurance
(A), distraction (C), or requesting another technician (D) might be helpful, they do not provide the same level of
physical safety as positioning the patient appropriately.
Question 2
Which of the following is considered a pre-analytical variable that can significantly affect laboratory test results?
A. Instrument calibration error
B. Reagent lot number change
C. Prolonged tourniquet application
D. Incorrect calculation of results
🟢 Correct Answer: C. Prolonged tourniquet application
,🔴 RATIONALE: The pre-analytical phase encompasses all steps from test ordering until the sample is ready for
analysis. Prolonged tourniquet application can cause hemoconcentration and changes in analyte levels .
Instrument calibration (A), reagent lot changes (B), and calculation errors (D) are all part of the analytical or
post-analytical phases.
Question 3
A Gram stain of a sputum specimen reveals numerous pus cells and gram-positive cocci in clusters. Which
organism is most likely associated with this finding?
A. Streptococcus pneumoniae
B. Staphylococcus aureus
C. Neisseria meningitidis
D. Klebsiella pneumoniae
🟢 Correct Answer: B. Staphylococcus aureus
🔴 RATIONALE: Staphylococcus aureus is a gram-positive coccus that characteristically appears in clusters. Its
presence in a purulent (pus cell-rich) sputum sample is consistent with a bacterial pneumonia . Streptococcus
pneumoniae (A) is also a gram-positive coccus but appears in pairs (diplococci). Neisseria meningitidis (C) is a
gram-negative diplococcus, and Klebsiella pneumoniae (D) is a gram-negative rod.
Question 4
, A patient has a prolonged Prothrombin Time (PT). This finding is most indicative of a deficiency in which of the
following?
A. Factor VIII
B. Factor IX
C. Factor VII
D. von Willebrand factor
🟢 Correct Answer: C. Factor VII
🔴 RATIONALE: The PT test evaluates the extrinsic pathway of coagulation, which includes Factor VII. Prolonged
PT is a classic indicator of Factor VII deficiency or the effect of anticoagulants like warfarin, which inhibit vitamin
K-dependent factors including Factor VII . Factors VIII (A) and IX (B) are part of the intrinsic pathway, assessed by
the Partial Thromboplastin Time (PTT). Von Willebrand factor (D) is assessed by specific platelet function and
vWF assays.
Question 5
An MLT must perform a manual WBC count. The blood is diluted and counted in a hemocytometer. If the
technician counts cells in all 9 large squares of the hemocytometer, the total is 150 cells. The dilution factor is
1:20. What is the WBC count in cells/µL?
A. 3,000 cells/µL
B. 3,333 cells/µL
