Why is the rib at b considered a true rib? t encloses the thoracic cavity and protects the vital organs within?

The statement above is FALSE.
The rib at B is considered a true rib BECAUSE IT IS DIRECTLY ATTACHED TO THE STERNUM.
There are twelve pairs of ribs in human, the first seven ribs are directly attached to the breast bone [sternum] and this is the reason why they are described as true rib. The other five ribs are considered to be false ribs because they are not directly attached to the sternum.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
