Care

QuestionAnswer
What is postpartum?From the delivery of the placenta & membranes to the return of a woman's reproductive system to its non-pregnant state - approx 6 weeks.
What is involution?the process by which the uterus returns to its normal size.

 

 

What is evidence of satisfactory involution?Firmness of uterus, rate of uterine descent & nature of lochia.
What is the normal rate of descent of the uterus?1st day postpartum - at or slightly above umbilicus, 2nd day - at or slightly below umbilicus, 3rd day - 1 finger below umbilicus, 4th day - 2 fingers below, by 10th day - behind symphysis - not detectable
What can impede involution?A prolonged labor, general anesthesia, difficult delivery, multiple pregnancies, full bladder, infection, retention of placental fragments.
What is the #1 postpartum concern?Hemorrhage
What are S/S of hemorrhage?Increase pulse rate, decrease in BP, excessive bright red bleeding, boggy uterus that does not respond to massage, unusual pelvic discomfort or back pain, cold, clammy skin
What are the panic levels for H&H?Hb <5.0g/dl & Hct of <20%, hemoglobin will decrease 1 to 1.5 g/dl & hematocrit will decrease 2-4% per 500 ml of blood loss
What are the early or immediate causes of hemorrhage?blood loss greater than 500 ml in first 24 hrs caused by uterine atony, laceration of the genital tract, retained placenta, adherent placenta.
What are later causes of hemorrhage?Retained placenta and infection are the most common causes.
What is lochia?the decidua (lining) which is cast off down to myometrium, a new endometrium is formed
What is lochia rubra and how long does it last?Bright red, tends to clot, serosanguineous, becoming more serous and less bloody - last 1-3 days.
What is lochia serosa and how long does it last?Dark red (or pinkish) to brond, sheds of decidua, looks less like blood - lasts 3-10 days
What is lochi alba and how long does it last?Whitish/yellowish discharge - lasts 10-14 days, may last 3-6 weeks and remain normal.
What is diastasis abdominis?separation of the rectus abdominis muscles may occur leaving part of abdominal wall with no support except skin, subcutaneous fat, fascia & peritoneum.
Why is bathing so important?There is an increased risk for infection during postpartum.
What is an episiotomy?A surgical incision of the perineal body - assess using REEDA - redness, edema, echymosis, discharge, approximation
What is a laceration?A tear in the perineal body which occurs in varying degrees.
1st degree lacerationtear through skin & structures that are superficial to muscle
2nd degree lacerationextends through perineal muscles - much like an episiotomy
3rd degree lacerationcontinues through anal sphincter muscle
4th degree lacerationinvolves anterior rectal wall
Sulcus teartear into the tissue of the vagina
What are some concerns involving the bladder?Pt should void within 6-8 hours following delivery, check for bladder distention if less than adequate amount voided - retention with overflow
What can cause bowel dysfunction?Delay in bowel function can be due to loss of abdominal muscle tone, fear of pain, sluggishness due to progesterone effect on smooth muscle function.

What is assessed in regards to emotional status?Is the mother dependent or independent? Is she depressed, is she bonding with the baby, does she understand whats going on?
What does antepartum mean?The time between conception and onset of labor, used interchangeably with prenatal
What does intrapartum mean?The time between the beginning of labor and the birth of the infant.
What does puerperium or postpartum mean?Time from birth of infant until woman's body returns to essentially prepregnant state.
What does para mean?The number of pregnancies in which the fetus has reached 20 or more weeks gestation when they are born regardless of live or still born.
What does abortion mean?Birth that occurs prior to the 20 weeks, either selective or spontaneous. Therapeutic - done to save mother or non-viable fetus.

What causes an amniotic fluid embolism?A small tear in the amnion or chorion high in the uterus allows fluid to enter maternal circulation.
What is disseminated intravascular coagulation?The coagulation sequence is activated by injury to the epithelium, or by bacterial particles or other foreign material. The result is disseminated clotting causing organ damage due to small clot occluding capillaries and consumptions of clotting factors.
What are the psychological adjustment stages?Taking in, taking hold and letting go.

QuestionAnswer
Normal pHpH (7.35-7.45)
< 7.35Acidosis
> 7.45Alkalosis
7.40is the exact normal

 

 

7.35-7.45Compensated
< 7.35 or > 7.45Uncompensated
CO2 (35-45)normal CO2 in artery
HCO3 (22-26)normal Bicarbonate in artery
Respiratory AcidosisCO2 > 45
Respiratory AlkalosisCO2 < 35
Metabolic AcidosisHCO3 <22
Metabolic AlkalosisHCO3 > 26
pH and HCO3 are cousinsthey go in the same direction for Acidosis and Alkalosis
But CO2 is an outsiderit goes the opposite direction for Acidosis and Alkalosis
Abnormal pH and CO2 in opposite directionsrespiratory problem
Abnormal pH and HCO3 in the same directionmetabolic problem
HCO3 and CO2 in the same directiontrying to compensate for abnormal pH
HCO3 and CO2 in opposite directionsboth imbalances (mixed)
What are some causes of low PaO2?Hypoxic Hypoxia--there’s just not enough of a supply of O2 ( COPD, pneumonia, ARDS, suffocation)
What are some causes of low PaO2?Anemic Hypoxia There’s plenty of O2—but not enough HGB to carry it to the tissues
What are some causes of low PaO2?Stagnant Hypoxia There may be enough O2 coming in and enough HGB to carry it--but the circulation is stagnant due to a decreased Cardiac Output. The O2 is not being adequately carried to the tissues.
What are some causes of low PaO2?Histotoxic Hypoxia Poisoning like Carbon Monoxide or Cyanide. Either the blood can’t carry the O2 or the cells can’t receive the O2 from the blood.
What is saturation?SaO2 (oxygen saturation) measures the percent of oxygen bound to hemoglobin. This tells weather the patient has HYPOXIA (decreased O2 in the tissues).
Normal SaO2 ?Greater that 95%
In Carbon Monoxide Poisoningthe HGB is saturated with Carbon Monoxide. Although the patient is hypoxemic because there is no room on the HGB for O2 to be carried—the Saturation looks good because it can’t distinguish between the two.
What does the PaO2 mean?The O2 tells us if the patient has HYPOXEMIA (decreased oxygen in the blood).
Normal PaO2 =80-100. (Hypoxemia = PaO2<80)
What does it do?PaO2 assesses Perfusion (gas exchange).
What does it do?PaCo2 asseses the adequacy of Ventilation (breathing pattern).
What does it do?The PaO2 is very important in determining your patient’s oxygen status and needs
Decreased pH with Decreased HCO3ACIDOSIS.
Increased pH with Increased HCO3ALKALOSIS.
Decreased pH with Increased CO2ACIDOSIS.
Increased pH with Decreased CO2ALKALOSIS.
If it is 7.35-7.45 (normal)is COMPENSATED
If the CO2 is <35 or >45--RESPIRATORY.
If the HCO3 is <22 or >26--METABOLIC.
If the pH is <7.35 or >7.45is UNCOMPENSATED.
Carbon Dioxide is anAcid
Increasing your respiratory rate(hyperventilation)you "blow off" CO2 decreasing your acid. Giving you ALKALOSIS
Decreasing your respiratory rate (hypoventilation)you retain CO2(acid) therefore increasing your CO2 giving you ACIDOSIS
Hydrogen or HCO3 is Bicarbonate orBasic or a base
If you have excess H+ and decreased HCO3(base):decrease in pHAcidosis; the kidneys will try to adjust to this by excreting H+ and retaining HCO3
When H+(acid) decreases and you hace increased HCO3(base)Alkalosis;Kidneys excrete HCO3(base), retains H+
