A) Plastic tubing should be longer than 3 feet.
B) The bell is used after using the diaphragm.

D) A diaphragm picks up low-pitched sounds.

Answer:

Explanation:

The statement that indicates the need for additional teaching is:

A) Plastic tubing should be longer than 3 feet.

In fact, longer tubing for a stethoscope can diminish sound quality and make it harder to hear the sounds clearly. The standard length for tubing is usually between 22 to 28 inches. Therefore, the statement about the plastic tubing being longer than 3 feet is incorrect and requires correction.
