NUR 148 Ch18 Test With
Solution
Fetal Oxygenation - ANSWER What's So Important About the
Fetal Heart Rate and the
Uterine Contractions?
Fetal Heart Rate/Tones - ANSWER Auditory and/or visual representation of
number
of time fetal heart beats per minute
110-160 bpm - ANSWER Normal range of fetal heart beat
Fetal Heart Rate Patterns - ANSWER The fetal heart develops certain patterns
which
can be auscultated or seen, that indicate if the
fetus is receiving an adequate supply of oxygen
Fetal well-being - ANSWER assessed during labor by evaluating how the fetal
heart responds to labor contractions
1. Hand-held doppler,
2. Continuous External fetal monitor,
3. Fetoscope,
,4. Continuous Internal fetal monitor - ANSWER Tools for Assessing the FHR
Contraction frequency - ANSWER • How often are the contractions coming?
Contraction duration - ANSWER • How long does each contractions last?
Contraction intensity - ANSWER • How strong are the contractions?
Uterine resting tone - ANSWER • Does the uterus return to a non-contracted
state between contractions? It's supposed to relax between contractions.
1. The Human Hand,
2. External
3. Internal continuous contraction monitoring - ANSWER Tools for Assessing
Uterine
Contractions
some baby's don't react well to stress of contractions - ANSWER Why So
Much Monitoring?
interrupted or stops - ANSWER Labor is physiologically stressful to the
fetus because, Blood flow (O2) to fetus is _____ during each contraction
Increases risk for fetal hypoxia - ANSWER • Especially in fetuses who are
already have
problems associated with decreased placental
blood flow
1. Hypertension,
2. Diabetes,
, 3. Maternal or fetal hemorrhage,
4. IUGR, (Intrauterine growth restriction)
5. Effects of some epidural medications - ANSWER problems associated with
decreased placental
blood flow
Untreated fetal hypoxia lead to hypoxemia, to
anaerobic metabolism, to production of lactic acid, to fetal acidosis, to
cellular/tissue/organ damage, to fetal death. - ANSWER What happens when
a fetus becomes hypoxic?
7.35 - ANSWER Acidosis: Blood pH of under ________,
The lower the pH, the more damage to fetal
tissues and organs
brain damage or cerebral
palsy, fetal or neonatal seizures, and death - ANSWER Poorly oxygenated
fetuses do not and they
become acidotic - if not treated in a timely
fashion, can cause _______, __________, and _______
1. Fetal heart rate and FHR pattern
assessment,
2. Contraction assessment - ANSWER Fetal Assessment in Labor
110-160 - ANSWER The fetus's heart rate,
