2 Theories of Onset of Labor -ANSWER ✔✔Mechanical Theory
Hormonal Theory
Mechanical Theory of Labor Onset -ANSWER ✔✔Based on the principle that as a
hollow organ becomes filled and distended, the organ tends to empty itself.
Examples are bladder and Sigmoid colon
Hormonal Theory of the onset of labor -ANSWER ✔✔Relates to the changes in
maternal estrogen and progesterone levels the maternal production of oxytocin and
prostaglandin and the increase in fetal cortisol. As pregnancy nears the end
progesterone decreases, estrogen rises causing increased sensitivity of the
myometrium to oxytocin which stimulates uterine contractions.
False labor -ANSWER ✔✔Contractions often irregular but may be regular for a
short time (1 to 2 hours). Interval between contractions stays the same. Contraction
intensity and duration remain the same. Contractions frequently stop when the
client ambulates or changes position. Contractions eventually cease with controlled
breathing, relaxation techniques, comfort measures or hydration. CERVIX MAY
SOFTEN but does NOT efface or dilate. Contraction felt above navel. No change
in cervical dilation and effacement.
true labor -ANSWER ✔✔Contractions occur at regular intervals. Interval between
contractions gradually shortens. Contractions increase in intensity and duration.
Contractions continue and often become stronger when the client ambulates.
Contractions are usually not stopped with controlled breathing, other relaxation
techniques, sedation, comfort measures or hydration. Cervix softens, effaces and
dilates. Contractions felt in lower back and radiate to abdomen. Produces cervical
dilation and effacement.
What are the 3 kinds of Lochia? -ANSWER ✔✔Rubra-Dark red discharge for 3-4
postpartum days
, Serosa-Pink-3 weeks post partum
Alba-Clear or white-2-6 weeks after serosa
What are the warning signs that there is problems with the Lochia? -ANSWER
✔✔Reverting to a previous stage
Strong Foul Odor
Rubra lasting for longer then 4 days
Excessive bleeding
What happens to the blood flow to the placenta during a contraction? -ANSWER
✔✔decreases
How is Blood Volume affected during pregnancy? -ANSWER ✔✔Plasma volume
increases by 50% which causes reduction in Hb concentration (Physiological
anaemia). Increase in red cell volume which is necessary for oxygen transportation.
Increase in leukocyctes. Increased iron metabolism (erythropoiesis). Decrease in
platelets and increase in clotting factors.
What is the affect on Blood Pressure during pregnancy? -ANSWER ✔✔Normal
pregnancy has limited affect on BP. There is very small affect on the systolic
venous pressure however the diastolic is lower in the first two trimesters and
returns to pre pregnancy pressure during the 3rd. The development on new
vascular beds and the relaxation of peripheral tone by progesterone result in
decreased resistance to flow.
What effects does labor cause on the GI: -ANSWER ✔✔decreased gastric motility
thirsty not hungry (ice chips only)
no solid food due to a chance of aspiration
Respiratory systems during labor: -ANSWER ✔✔increase depth and rate of
respirations
hyperventilation
help slow her breathing down
Urinary system during labor: -ANSWER ✔✔reduces sensation of a full bladder
full bladder can slow birth of child
