You are presented with results from various laboratory stations. Provide the answers for Hemostasis, Blood Grouping, and BMI calculation.

here are the answers for the remaining stations:

Station 4: Hemostasis (Bleeding & Clotting)

• Question A: Identify the method being used. The method being used is Ivy's Method for Bleeding Time.

• Question B: What is the standard pressure maintained in the BP cuff for this test? The standard pressure maintained in the BP cuff for this test is $\boxed{40 \text{ mmHg}}$.

• Question C: A patient has a normal Clotting Time but a prolonged Bleeding Time. What is the likely defect? The likely defect is Platelet deficiency (Thrombocytopenia) or Platelet dysfunction.

Station 5: Blood Grouping

• Question A: What is the blood group of this patient? Based on the clumping in Well A and Well D (Rh), and smooth in Well B, the blood group of this patient is A Positive.

• Question B: What is the 'Principle' behind this test? The principle behind this test is Antigen-Antibody Agglutination.

• Question C: Which blood group is the 'Universal Donor' for Packed RBCs and why? The universal donor for Packed RBCs is O Negative because it lacks A, B, and D (Rh) antigens, meaning it will not be agglutinated by antibodies in the recipient's plasma.

Station 6: BMI & Physical Constants

• Question A: A subject weighs 80kg and is 1.6m tall. Calculate the BMI. The formula for Body Mass Index (BMI) is: $$\text{BMI} = \frac{\text{weight (kg)}}{\text{height (m)}^2}$$ Given: Weight = $80 \text{ kg}$ Height = $1.6 \text{ m}$
