Answer 1

ANSWER

   * False. Pulse oximetry do not require use of a blood sample.

   * It is a non invasive method and it help to measure oxygen

   saturation by placing a pulse oximeter to the extremities.

Match the following.

* CT scan Use numerous 2D xray strikes to create a 3D view of the body.

* MRI Produce a magnetic field exciting hydrogen atoms electrons.

* PET scan Maps electrical activities in the body by use of radioactive tracer

isotopes.used for cancer staging.

*X-RAY   Short wavelength and high energy than visible light that passes

   through soft tissues creating a 2D image.

* ULTRASOUND. Uses sound waves to visualize soft tissues.
