Positioning

Question 1

The axiolateral, or horizontal beam, projection of the hip requires the IR to be placed

Answer 1

1. parallel to the long axis of the femoral neck

2. in contact with the lateral surface of the body

Question 2

blood pressure.

Answer 2

he normal blood pressure range for men and women is 110 to 140 mmHg systolic reading (top number) and 60 to 80 mmHg diastolic reading (bottom number). Systolic pressure is the contraction phase of the left ventricle, and diastolic pressure is the relaxation phase in the heart cycle
