Tracheostomy Procedure

# In tracheostomy, the entry into the trachea is through the:
A. Cricoid cartilage
B. First tracheal ring
C. Second and third tracheal ring
D. Fourth and fifth tracheal ring

In tracheostomy, the entry into the trachea is through 2nd - 4th tracheal rings. Entry through 1st ring results in tracheal stenosis and entry through 5th - 7th rings is very difficult. 

Entry through cricothyroid membrane is called cricothyroidotomy which ia a life saving procedure when endotracheal intubation is not possible.

# The maximum permissible dose of radiation to the operator of an X ray machine is:
A. 0.05 rem per year
B. 0.5 rem per year
C. 5.0 rem per year
D. 50 rem per year

The correct answer is C. 5.0 rem per year.
