Describes the relationship of a given points of the presenting part of the fetus to the designated point of the maternal pelvis.

42
Q

What are the four landmarks of fetal presenting parts?

43
Q

When charting fetal position what does the first letter indicate?

weather the presenting part of the child is tilted towards the left or the right of the maternal pelvis.

44
Q

When charting the fetal position what does the second letter stand for?

A 
The presenting part of the fetus
O for occipit
S for sacral
M for mentum

45
Q

When charting fetal position what does the third letter stand for?

A

It defines a location of the presenting part in relation to the anterior A, posterior P, if it is in the side of the pelvis it is designated as transverse.

46
Q

Define fetal station.

A

Refers to the relationship of the presenting part of the maternal pelvis to the ischial spines of the pelvis. It is measured in centimeters and is referred to as a minus or a plus

47
Q

Define zero station.

A

It is designated to when the presenting part is at the level of ischial spines.

48
Q

Define fetal engagement

A

When the largest diameter of the fetal presenting part, usually the head, enters the smallest part of the maternal pelvis. Fetus is engaged in the pelvis when the presenting part reaches zero station. Determined by a pelvic exam or vaginal exam

49
Q

Define floating or Ballotable

A

A fetal head that has not descended and has not become fixed in the maternal bony pelvis. Upon examination the head is able to move up-and-down. When the fetal head is engaged it cannot be moved?

50
Q

True or false on the fetal head is engaged it cannot be moved?

A

True

51
Q

What is the purpose of the maternal assessment during labor and birth through vaginal exam?

A

To assess the amount of cervical dilation, the percent of effacement and the status of the membranes, and the status of the fetal head (presentation and position)

52
Q

How is effacement recorded?

A

%

53
Q

How is station recorded?

A

Ballotable and -2 to +3
