EXAM 2026-2027 160

QUESTIONS AND CORRECT DETAILED ANSWERS

WITH RATIONALES ( ANSWERS)

Explain transient interruptions in fetal oxygen supple during labor.

A normal part of labor. As contractions build increased uterine pressure

prevents blood from entering/leaving the intervillous space. During the

peak the fetus relies completely on its oxygen reserve (an aerobic

challenge that is not an issue for a health fetus.

Define Uteroplacental insufficiency (UPI)

Chronic deficiency of placenta function, usually from an interruption of

oxygenation pathway due to abruption, mat. hypo or hypertension or

other issues. Infant is not tolerant of contractions. Can result in fetal

grow restrictions (FGR)

Auscultation of Fetal Heart Sounds tell you what information?

Where is the best place to listen?

Assess baseline FHR

Determine rhythms (regular vs irregular)

ID accelerations and deceleration's but not the type of deceleration

(early/late/variable)

The fetal heartbeat is best heard over the fetal back.

Leopold's Maneuvers

Palpation to determine presentation and position of the fetus and aid in

location of fetal heart sounds.

Head=hard, round, movable object

Buttocks=soft and irregular shape

Back=smooth, hard surface felt on one side of the abdomen

Irregular knobs and lumps on opposite side of abdomen may be hands,

feet, elbows, and knees

Handheld Fetal Doppler

Uses sonar to track the fetal myocardium & converts movement into

sound. If placed incorrectly may pick up maternal heart.

Perform Leopold's maneuvers to find fetal back, locate heartbeat, count

FHR, check mothers pulse and compare.

How can you determine if the placenta is functioning optimally?

ID risk factors such as HTN (=vasoconstriction), Maternal smoking,

abruption, post-term pregnancy, maternal diabetes and consider FHR

characteristics

How much blood normally flows to the placenta?

500-700ml to the uterus per minute, 80% is directed to the placenta

How many uterine contractions can be tole ?

This depends on oxygenation which is reflected in FHR variability and

accelerations on the fetal monitor tracings.

What conditions impact the following pathways:

Umbilical cord

Maternal inhalation

Placenta

Uterus

Fetus

Maternal circulation

Umb. cord -Proplapse

Mat. inhalation -Asthma
