BBK99E1 PRACTICAL FINAL NEWEST EXAM 2026-
2027 WITH COMPLETE QUESTIONS AND CORRECT
DETAILED ANSWERS |BRAND NEW VERSION
1. Which of the following are common methods for
measuring body temperature in a clinical setting?
A. Oral thermometer
B. Rectal thermometer
C. Axillary thermometer
D. Infrared forehead thermometer
Rationale: Different methods are used based on patient
condition and accuracy requirements. Oral and rectal are
traditional; axillary is less accurate; infrared is non-contact.
Correct answers: A, B, C, D
2. When performing a blood pressure measurement, which
steps are essential?
A. Patient seated and relaxed
B. Arm supported at heart level
C. Cuff placed over clothing
D. Inflating cuff too quickly
Rationale: Proper positioning ensures accurate readings.
Cuff should be on bare skin and inflated at a steady rate.
Correct answers: A, B
3. Which of the following are sterile techniques in a medical
laboratory?
A. Wearing gloves and mask
, B. Using a Bunsen burner flame to sterilize loops
C. Working in a laminar flow hood
D. Touching sterile instruments with bare hands
Rationale: Sterile technique prevents contamination.
Direct contact with sterile instruments violates aseptic
principles.
Correct answers: A, B, C
4. In preparing a blood smear for microscopic examination,
which steps are required?
A. Place a drop of blood on the slide
B. Use a spreader slide to smear the blood evenly
C. Heat-fix the slide
D. Stain with Wright or Giemsa stain
Rationale: Proper smear preparation is critical for accurate
cell morphology assessment.
Correct answers: A, B, C, D
5. Which safety measures are necessary when handling
biological specimens?
A. Wear personal protective equipment (PPE)
B. Dispose of sharps in puncture-resistant containers
C. Wash hands after handling specimens
D. Place all specimens directly in the sink
Rationale: PPE and proper disposal prevent infection;
specimens should never go in sinks.
Correct answers: A, B, C
,6. Which of the following are common steps in urinalysis?
A. Collect midstream urine
B. Centrifuge sample if needed
C. Observe color, clarity, and odor
D. Directly heat sample over flame
Rationale: Proper collection and observation are essential;
heating over flame can be hazardous and is not standard
practice.
Correct answers: A, B, C
7. Which instruments are used in a basic physical
examination?
A. Stethoscope
B. Otoscope
C. Sphygmomanometer
D. Scalpel
Rationale: Stethoscope, otoscope, and
sphygmomanometer are essential for general exams;
scalpel is for surgical procedures.
Correct answers: A, B, C
8. Which of the following techniques help prevent cross-
contamination in a lab?
A. Using disposable pipette tips
B. Cleaning work surfaces regularly
C. Sharing gloves among colleagues
D. Autoclaving reusable instruments
Rationale: Proper hygiene and sterilization prevent
, pathogen spread; sharing gloves increases contamination
risk.
Correct answers: A, B, D
9. In aseptic technique for injection, which steps are
correct?
A. Wash hands before procedure
B. Clean injection site with alcohol swab
C. Use a sterile needle and syringe
D. Recap needle after use with fingers
Rationale: Safety requires sterile equipment and hand
hygiene; recapping with fingers increases needle-stick risk.
Correct answers: A, B, C
10. Which of the following are components of a
complete blood count (CBC)?
A. White blood cell count
B. Red blood cell count
C. Hemoglobin concentration
D. Urine glucose
Rationale: CBC measures blood cell counts and
hemoglobin, not urine glucose.
Correct answers: A, B, C
11. Which steps are correct when performing a sterile
urine culture?
A. Collect midstream urine
B. Use sterile container
C. Plate sample on nutrient agar immediately
