About PIO 218 at Bayelsa Medical University Yenagoa
PIO 218 at Bayelsa Medical University Yenagoa (BMU) covers foundational topics in clinical diagnostics and physiology, including pregnancy tests, blood glucose measurement, cardiovascular responses to exercise and posture, arterial blood pressure and pulse measurement, blood grouping, hematology, and clinical biochemistry. This course is designed for medical and health science students who need to understand the principles and procedures behind common diagnostic tests and physiological assessments.
Practicing past questions by topic helps you master the specific terminology, normal values, and procedural steps that BMU examiners expect. Topic-focused revision allows you to identify patterns in how concepts like fasting plasma glucose categories or diabetes diagnostic criteria are tested, improving recall speed and accuracy during the exam.
Topics covered

3. What is the purpose of the control line in a pregnancy test strip?
4. A woman tests negative for pregnancy 5 days after a missed period. What might explain this result?

What are the diagnostic criteria for diabetes mellitus using fasting plasma glucose?
According to standard clinical guidelines, a fasting plasma glucose (FPG) level of 126 mg/dL (7.0 mmol/L) or higher on two separate tests indicates diabetes. An FPG between 100 and 125 mg/dL (5.6–6.9 mmol/L) is considered impaired fasting glucose (pre-diabetes), and below 100 mg/dL (5.6 mmol/L) is normal.
How does exercise affect heart rate and blood pressure?
During acute exercise, heart rate increases to supply more oxygen to muscles. Systolic blood pressure typically rises with exercise intensity, while diastolic blood pressure remains relatively stable or may slightly decrease. After exercise, heart rate and blood pressure gradually return to baseline, with regular exercise lowering resting heart rate and blood pressure over time.
What is the principle behind the human chorionic gonadotropin (hCG) pregnancy test?
Pregnancy tests detect the presence of human chorionic gonadotropin (hCG), a hormone produced by the placenta after implantation. Most tests use antibodies that bind specifically to hCG in urine or blood, producing a visible color change or signal. hCG levels rise rapidly in early pregnancy, making it detectable as early as 10 days after conception.
How is arterial blood pressure measured using a sphygmomanometer?
Arterial blood pressure is measured by placing a cuff around the upper arm, inflating it to occlude the brachial artery, then slowly deflating while listening with a stethoscope. The first Korotkoff sound indicates systolic pressure, and the disappearance of sounds indicates diastolic pressure. The patient should be seated with the arm at heart level and rested for at least 5 minutes before measurement.
