The universal donor is blood type:

  1. B
  2. O
  3. A
  4. D

Answer(s): B

Explanation:

The universal donor blood type is O negative (O-). This means that individuals with this blood type can donate blood to recipients of any other blood type. This is due to the absence of A and B antigens on the red blood cells and the lack of Rh antigen, which prevents the immune system of the recipient from recognizing the donor blood as foreign. The concept of universal donor is fundamental in emergency situations when there's no time to cross-match blood types.

  2. the chance of shocking the assistant
  3. the chance of shocking the
  4. the chance of shorting the patient machine

Answer(s): A

Explanation:

The purpose of applying paste or jelly when running an EKG (Electrocardiogram) is to reduce skin resistance. This conductive gel ensures better conductivity between the skin and the electrodes, resulting in a clearer and more accurate recording of the heart's electrical activity. Without the gel, poor contact can lead to high resistance and artifacts in the EKG trace.
