Cards

Term

The exact mechanism that initiates labor is:

A. uterine stretching

B. oxytocin stimulation

C. cervical pressure

D. unknown

E. placental age

F. progesterone withdrawal

Definition

D. unknown

-all of the other choices are suspected causes or thought to work in combination to cause labor but the true initial cause remains unknown

Term

Which of the following is not one of the 4 Ps of pregnancy?

A. passage

B. pain

C. power

D. psyche

E. passenger

Definition

B. pain

-passage refers to the route the fetus must travel when leaving the uterus, ending at the external perineal area

-passenger refers to the fetus and its ability to move through the passage

-power refers to the force of uterine ctx

-psyche refers to the feelings the pt brings to labor

Term

Apnea is considered a sign of respiratory distress in the newborn when the apnea last longer than:

A. 10 sec

B. 15 sec

C. 20 sec

D. 25 sec

Definition

C. 20 sec

-all newborns have brief periods of apnea that usually last a few seconds.  Rule of thumb is by the time you notice it the baby will start breathing again.  If it lasts longer than 20 secs (you should have done tactile stimulation by then) than it is true apnea and a sign of RD

Term

Which crosses the placenta?

A. glucose, not insulin

B. insulin, not glucose

C. both insulin and glucose

D. neither insulin or glucose

Definition

A. glucose not insulin

-this abundance of glucose causes macrosomia (birth weight greater than 4000g)

-macrosomia can cause birth trauma but also the newborn will be born hyperglycemic which quickly turns to hypoglycemia

Term

A diabetic mother gives birth to a 4500g newborn.  The initial serum glucose is high.  What interventions are the RN anticipating?  Select all that apply

A. feed the baby early

B. admin insulin

C. assess for birth trauma

D. assess respiratory function

E. maintain thermoregulation

Definition

A,C,D,E

-FEED THE BABY EARLY, the serum glucose is going to drop as a result of being cut off from mom's supply.  Feeding early will ward off hypoglycemia, this baby will need frequent serum glucose checks

-birth trauma caused by large size

-when the infant becomes hypoglycemic he has less glucose to use for energy and can become hypothermic.  Hypothermia will raise the metabolic rate which increases oxygen need, decreases surfactant production, and causes hypoxia

Term

What is the major difference between true labor and false labor?

A. when it occurs

B. cervical change

C. hCG level

D. location and amount of pain

Definition

B. cervical change

-False labor: NO CERVICAL CHANGE, feels like the baby is "balling up", pain in low abd/groin, ambulation alleviates pain

 

-True labor: CERVICAL CHANGE OCCURS, pain increases in intensity and frequency, ambulation speeds up the process

Term
Define effacement
Definition

Term
Define engagement
Definition

-the head has entered the pelvis

-as the baby engages pressure is created on the cervix forcing effacement and dialation

Term
Define fetal lie
Definition

A. cephalic

B. breech

C. brow

D. shoulder

Definition

D. shoulder

-the shoulder, iliac crest, hand, or elbow present

-can be caused by relaxation of the abd walls, pelvic ctx, or placenta previa

-the fetus must be turned before delivery however this is usually unsuccessful unless the fetus is SGA or preterm

-ALMOST ALWAYS requires a C/S delivery

Term

Which cardinal movement of labor is characterized by the fetal head moving into the pelvic inlet?  At the end of this movement the head contacts the posterior vaginal floor.

A. flexion

B. descent

C. internal rotation

D. engagment

Definition

B. descent

-the head has passed the ischial spine and continues down into the pelvic inlet

-progresses intermittently with ctx

Term

This cardinal movement of labor occurs when the fetal head moves forward so that the chin is pressed against the chest.

A. flexion

B. extension

C. engagement

D. external rotation

Definition

A. flexion

-occurs during descent and is caused by resistance of the fetal head against the pelvic floor

-allows the smallest diameter of the fetal head to descend through the pelvis

Term

This cardinal movement of labor is the rotation that allows the fetal head to pass through the ischial spines.

A. internal rotation

B. external rotation

C. transverse rotation

D. oblique rotation

Definition

A. internal rotation

-the head rotates about 45o as it meets resistance of the pelvic floor

-this places the widest part of the shoulders in line with the widest part of the pelvis

-this also places the widest part of the fetal head in line with the widest part of the pelvic outlet

Term

The cardinal movement of labor that delivers the head, face, and chin.

A. expulsion

B. external rotation

C. extension

D. flexion

Definition

C. extension

-descent is temporarily halted as the shoulders are too wide to pass through the pelvis

Term

The cardinal movement of labor where the head rotates back to the original position seen at the beginning of descent.

A. internal rotation

B. extension

C. flexion

D. external rotation

Definition

D. external rotation

-descent is halted during extension because the shoulders are too wide to pass, at this point the head and shoulders externally rotate the 45o they earlier had internally rotated

TABLE 7
Technique for Intravaginal Application of Misoprostol (Cytotec) Tablets


Place one fourth of a tablet of misoprostol intravaginally, without the use of any gel (gel may prevent the tablet from dissolving).

The patient should remain recumbent for 30 minutes.

Monitor fetal heart rate and uterine activity continuously for at least three hours after misoprostol application before the patient is allowed to ambulate.

When oxytocin (Pitocin) augmentation is required, a minimum interval of three hours is recommended after the last misoprostol dose.

Not recommended for cervical ripening in patients who have a uterine scar.

Term
Prostoglandin Gel application
Definition

Technique for Placement of Dinoprostone Gel (Prepidil)


Patient selection:

 

Patient is afebrile.

 

No active vaginal bleeding is present.

 

Fetal heart rate tracing is reassuring.

 

Patient gives informed consent.

 

Bishop score is < 4.

Bring gel to room temperature before application, per manufacturer's instructions.

Monitor fetal heart rate and uterine activity continuously starting 15 to 30 minutes before gel introduction and continuing for 30 to 120 minutes after gel insertion.

Introduce the gel into the cervix as follows:

 

If the cervix is uneffaced, use the 20-mm endocervical catheter to introduce the gel into the endocervix just below the level of the internal os.

 

If the cervix is 50 percent effaced, use the 10-mm endocervical catheter.

After application of the gel, the patient should remain recumbent for 30 minutes before being allowed to ambulate.

May repeat every six hours, up to three doses in 24 hours.

End points for ripening include strong uterine contractions, a Bishop score of 8, or a change in maternal or fetal status.

Maximum recommended dosage is 1.5 mg of dinoprostone (3 doses) in 24 hours.

Do not start oxytocin for six to 12 hours after placement of the last dose, to allow for spontaneous onset of labor and protect the uterus from overstimulation.
