T/F: When performing vaginal examinations on laboring women, wear a clean glove lubricated with tap water to reduce discomfort.
F: Sterile gloves and sterile gell lubricant must be used to prevent infection.
T/F: When performing vaginal examinations on laboring women, perform the examination every hour during the active phase of the first stage of labor.
F: Vaginal examinations should only be performed as indicated to limit maternal discomfort and reduce the risk for transmission of infection, especially when rupture of membranes occurs.
T/F: Examinations are never done by the nurse if vaginal bleeding is present.
T: Because the bleeding could be a sign of placenta previa and a vaginal examination could result in further separation of the low-lying placenta.

B. Keep the protruding cord moist with warm sterile normal saline compresses.
The hips should be elevated using a ____ when cord prolapse is detected.
Sims or knee-chest position
T/F: Following rupture of membranes, a prolapse of the cord was noted on vaginal examination. A recommended action to alleviate cord compression would be to insert a Foley catheter to keep the bladder empty.
F: A distended bladder has a beneficial effect; it elevates the presenting part and inhibits uterine contractions, so a catheter insertion is not recommended.
T/F: Following rupture of membranes, a prolapse of the cord was noted on vaginal examination. A recommended action to alleviate cord compression would not be to attempt to reinsert the cord.
T: Never attempt to reinsert the cord because it may be injured in the process.

T/F: To assess the characteristics and pattern of uterine contractions, place the hand on the abdomen below the umbilicus and palpate uterine tone with the fingertips.
F: Many women may experience labor pain in the lower segment of the uterus (i.e. below the umbilicus) which may be unrelated to the firmness of the contraction detectable in the uterine fundus.
T/F: Assess uterine contractions every 30 minutes throughout the first stage of labor.
F: Assessment of uterine activity is performed in intervals based on the stage of labor. As labor progresses, this assessment is performed more frequently.

T/F: The second stage of labor begins with full cervical dilation and 100% effacement.
T/F: Woman may experience a strong urge to bear down in the first stage of labor.
True: Many women may have an urge to bear down when the presenting part is below the level of the ischial spines. This can occur during the first stage of labor, as early as 5-cm dilation.
Nurses can help their patients by keeping them informed about the distinctive stages of labor. Which description of the phases of the first stage of labor is accurate?
C. Active: Moderate, regular contractions; 4- to 7-cm dilation; duration of 3 to 6 hours
T/F: Latent phase of first stage: Mild, regular contractions; no dilation; bloody show; duration of 2 to 4 hours
F: The latent phase is characterized by mild-to-moderate, irregular contractions; dilation up to 3 cm; brownish-to–pale pink mucus, and a duration of 6 to 8 hours.
T/F: Transition phase of first stage: Very strong but irregular contractions; 8- to 10-cm dilation; duration of 1 to 2 hours
F: The transition phase is characterized by strong- to–very strong, regular contractions; 8- to 10-cm dilation; and a duration of 20 to 40 minutes.

C. Appearance (shape and height).
T/F: Uterine contractions are described in terms of frequency, intensity, duration, and resting tone.
Concerning the third stage of labor, nurses should be aware that:
D. An expectant or active approach to managing this stage of labor reduces the risk of complications.
T/F: The placenta eventually detaches itself from a flaccid uterus.
F: The placenta cannot detach itself from a flaccid (relaxed) uterus. It must be firm and contracting to the villi to break away.
Active management facilitates placental separation and expulsion, reducing the risk of complications. This must occur within ___ time-frame and if not complete with ___, the placenta is considered to be rtetained and interventions to hasten delivery instituted.

F: sips of clear fluid
Why is the ice chips and sips of clear fluids practise beign challenged?
Because regional anesthesia is used more often than general anesthesia, even for emergent cesarean births, and so women are awake and able to protect their airways.
Women in labor will usually change their position spontaneously. If they do not do so every ___, assist her to so so. The ___ position is preferred because it ___.
30 to 60 minutes
promotes optmal uteroplacental and renal blood flow.
A women with ___ may not be able to squat, but may assume the ___ position.
hands and knees
Some maternal positions during labor and birth
Hands and Knees
Advantages of Semirecumbent
At least 30 degrees and pillow under one hip to prevent supine hypotension
The greater the angle, the more gravity will promote fetal descent andf progress of contractions
Position is convenient for rendering cxare measures and external fetal monitoring
Advantages of Lateral
Left or right side-lying.
Removes pressure from vena cava (enhances uteroplacental profusion) and back (relieves backache).
Associated with less frequent, but more intense contractions.
Good fetal monitor tracings possible, but more difficult.
May be used as birthing position.
Takes pressure off of perineum allowing it to stretch gradually and in so doing reduce the risk of trauma to it.
Advantages of upright
Downward pressures cause impulses from cervix to pituitary to increase, resulting in more oxytocin increasing the intensity of contractions, but with less pain
Fetus is aligned with pelvis and pelvic diameters are widened slightly
Adbvantages of Hands and Knees
Ideal position for posterior positions of the presentign part.
Gravity cause the fetal back to rotate with the head.

Primary powers of labor that act involuntarily for birth and expulsion of placenta, but also to prevent hemorrhage
Pre-eclampsia is a medical condition in which hypertension arises in pregnancy (gestational hypertension) in association with significant amounts of protein in the urine.
Pre-eclampsia is a set of symptoms rather than any causative factor, and there are many different causes for the condition.
It appears likely that there are substances from the placenta that can cause endothelial dysfunction in the maternal blood vessels of susceptible women.
While blood pressure elevation is the most visible sign of the disease, it involves generalized damage to the maternal endothelium, kidneys, and liver, with the release of vasoconstrictive factors being secondary to the original damage.
Pre-eclampsia may develop from 20 weeks' gestation (it is considered early onset before 32 weeks, which is associated with an increased morbidity).
Its progress differs among patients; most cases are diagnosed before labor typically would begin.
Pre-eclampsia may also occur up to six weeks after delivery. Apart from Caesarean section and induction of labor (and therefore delivery of the placenta), there is no known cure.
It is the most common of the dangerous pregnancy complications; it may affect both the mother and fetus.

Perineum: On side, lift upper buttock and inspect perineum and assess for hemorrhoids
Dirty Duncan & Shiney Shultz
"Dirty Duncan" and "Shiny Schultz" are ways to remember the presentation of the placenta. Duncans are called "dirty" because they come out messily, with trailing membranes, and a good amount of blood. Shultz are shiny because the fetal side comes out first, with the maternal side, blood and any clots wrapped up neatly in the membranes. Duncan placentas are usually because the placenta was low-lying. Low-lying placentas tend to be followed with a good amount of bleeding after, and because it was low-lying, the usual massage etc., may not work.IME, those dirty Duncans often need a shot of pit to control bleeding, more so than the Shultz, but not enough for me to routinely administer pit (pitocin), but enough for me to make sure I know where it is right away.So, maybe your midwife eyeballed the amount of blood coming after the placenta and just wasn't comfortable with it.
