QUESTION
Ventral deviation of head is called?
OPTIONS
(A) Breech presentation
(B) Vertex presentation
(C) Dog sitting posture
(D) Transverse presentation
ANSWER
(B) Vertex presentation
EXPLANATION
Mild downward flexion of the fetal head can bring the forehead or vertex against the maternal pelvic inlet, producing the posture traditionally termed vertex presentation. Breech refers to a posterior fetus with retained hindlimbs, dog-sitting posture involves abnormal engagement of the hindquarters in an anteriorly presented fetus, and transverse presentation describes the fetal long axis lying across the maternal axis. More severe ventral head deviations have other names.
