Maternity Nursing - Flashcards
*Content warning: This nursing education video and article discuss pregnancy loss, including miscarriage, hydatidiform mole, and ectopic pregnancies.
This article explores some of the complications of pregnancy, including miscarriage (or spontaneous abortion), hydatidiform mole (molar pregnancy), and ectopic pregnancies.
This series follows along with our Maternity Nursing Flashcards, which are intended to help RN and PN nursing students study for nursing school exams, including the ATI, HESI, and NCLEX.
Miscarriage
A spontaneous abortion, also known as a miscarriage, is the loss of a pregnancy prior to 20 weeks gestation due to natural causes.
The word “abortion” often brings to mind an induced or therapeutic abortion, such as a surgical or medical abortion that a patient chooses to have. But the word “abortion” actually means a termination of pregnancy for any reason. A spontaneous abortion, then, is a medical term that refers to any pregnancy that was lost for some reason through no action of the patient. It happened spontaneously.
Remember that patients are most likely not medically literate. They don’t know that abortion means any sort of loss of a pregnancy for any reason. So while it’s very important to use the correct terminology in charting, when talking to your patients, use simple, layman’s terms, such as “miscarriage,” so as not to cause unwarranted confusion or concern.
Types of miscarriages
There are several different types of spontaneous abortion (miscarriage), including threatened, inevitable, incomplete, complete, or missed abortion. Each has its own diagnostic code for billing and insurance purposes.
Threatened miscarriage
The signs and symptoms of a threatened miscarriage include light bleeding, no cervical changes, mild cramping, and no passage of fetal tissue.
Inevitable miscarriage
The signs and symptoms of an inevitable miscarriage include moderate bleeding, cervical dilation, rupture of membranes, strong cramping, and no passage of fetal tissue.
Incomplete miscarriage
The signs and symptoms of an incomplete miscarriage include heavy bleeding, cervical dilation, severe cramping, and the passage of some fetal tissue.
Complete miscarriage
The signs and symptoms of a complete miscarriage include a decrease in pain and bleeding after the passage of all fetal tissue.
Missed miscarriage
The signs and symptoms of a missed miscarriage include spotting, no cervical dilation, and no cramping. In a missed miscarraige, the non-viable embryo is retained in the uterus.
Treatment for miscarriage
The treatment for a miscarriage varies based on the type of miscarriage and how advanced the pregnancy.
Dilation and curettage (D&C)
Dilation and curettage, also known as "D&C," is a procedure in which the cervix is dilated to allow surgical instruments to be passed through it and into the uterus. Curettage refers to a kind of a scraping motion — this treatment requires the uterus to be physically cleaned of the pregnancy.
During a D&C, the patient will likely be given some very light medication, usually a benzodiazepine, such as Valium, or Versed (midazolam), which helps sedate the patient without rendering them unconscious.
In a D&C, the cervix is numbed with Lidocaine to help prevent discomfort, but the patient will likely experience cramping, heavier bleeding, and the passage of clots.
With a D&C, the provider may be able to send samples of the products of conception to the lab to see what caused the miscarriage, for example, a genetic abnormality in the fetus.
Prostaglandins (misoprostol)
One way to deal with a miscarriage with medicines is to use prostaglandins (e.g., misoprostol). Misoprostol allows the cervix to soften and dilate on its own to allow for easier passage of the pregnancy contents.
Rhogam
Rhogam, short for “Rh immune globulin,” is a medication that can be given to Rh-negative pregnant patients to help prevent them from developing antibodies against the Rh protein present in the blood of Rh-positive babies. When a miscarriage has occured in an Rh-negative patient, rhogam is administered within 72 hours of the miscarriage to help mitigate any pelvic or abdominal trauma or vaginal bleeding.
Hydatidiform mole (molar pregnancy)
Hydatidiform mole or molar pregnancy is a very rare but serious complication, characterized by the abnormal growth of trophoblastic villi in the placenta, which prevents normal embryo maturity.
A healthy trophoblast is a thin layer of cells that helps a developing embryo attach to the wall of the uterus, protects the embryo, and forms a part of the placenta. The villi in the uterus are tiny hairs that sprout from the chorion (part of the placenta) to provide maximal contact area with maternal blood.
There are two types of molar pregnancy: partial, where there is embryonic tissue present; and complete, where embryonic tissue is absent.
Hydatidiform mole can lead to gestational trophoblastic disease, e.g., choriocarcinoma (a type of uterine cancer).
Signs and symptoms of a molar pregnancy
The signs and symptoms of a molar pregnancy include dark vaginal bleeding, often described as having the consistency or color of prune juice, that is, a dark brown-purplish color.
Another sign of hydatidiform mole is a larger uterus or higher fundal height than expected for the gestational age of the fetus.
Other signs and symptoms include high hCG levels, cramping, nausea and vomiting, and the passage of tissue described as “grape-like clusters.”
Diagnosing a molar pregnancy
Hydatidiform mole is diagnosed with an ultrasound and will usually look like TV static or snow.
Treatment of a molar pregnancy
The treatment for a molar pregnancy is surgical uterine evacuation (D&C). This pregnancy is irremediably abnormal, and it needs to be removed from the uterus entirely.
Additionally, following surgery, the patient requires hCG monitoring to ensure that their hCG levels return to zero, that is, back down to normal.
Patient teaching for molar pregnancy
hCG monitoring must continue for six months following the D&C.
The patient must also avoid pregnancy for one whole year. This is because the combination of a pregnancy and high hCG levels makes it difficult to monitor for a choriocarcinoma (which also causes an increase in hCG). "Chorio-" refers to the chorion, part of a developing placenta; carcinoma is cancer. A patient who has experienced a molar pregnancy will be at risk for developing a choriocarcinoma, which is why it is so important to monitor hCG levels (and why it is important not to experience a pregnancy, as this will make it harder to monitor for those hCG levels).
Ectopic Pregnancy
An ectopic pregnancy is a deadly complication of pregnancy, and it is very important to catch it as soon as possible. It occurs when a pregnancy is not growing in the correct place (i.e., inside the uterus). “Ecto-” means outside, and an ectopic pregnancy is a pregnancy that grows outside the uterine cavity, most often in the fallopian tubes. But an ectopic pregnancy can also occur outside of the uterus entirely, for example in the abdomen or the pelvis.
An ectopic pregnancy is a rare complication of pregnancy, in which the pregnancy will not develop normally while putting the patient at significant risk for complications, including hemorrhage and death.
Risk factors for ectopic pregnancy
The risk factors for an ectopic pregnancy include a history of STIs (sexually transmitted infections, such as chlamydia), a history of a previous ectopic pregnancy, the use of an IUD, previous tubal surgery, or previous, multiple pregnancy losses.
Signs and symptoms of ectopic pregnancy
An ectopic pregnancy may be visible on an initial ultrasound, early in the patient's pregnancy.
If not seen at that initial visit, the more common signs and symptoms of an ectopic pregnancy include unilateral (one-sided) stabbing pain in the lower abdomen, usually occurring between five and nine weeks, and vaginal bleeding (i.e., “spotting”). Additionally, signs and symptoms of a hemorrhage (hypotension, tachycardia, pallor) may also indicate an ectopic pregnancy.
Treatment for ectopic pregnancy
Treatment for an ectopic pregnancy may include the medication methotrexate. When given to a patient, methotrexate causes the pregnancy to end by dissolving the pregnancy so the body can absorb it. This will save the fallopian tube.
Surgical options include salpingostomy (a tubal incision to remove an ectopic pregnancy) or salpingectomy (the removal of the fallopian tube). These are emergency procedures to remove the pregnancy so the patient does not hemorrhage, go into shock, and die.
Patient care for all forms of miscarriage
Any time you have a patient who experiences a miscarriage, be prepared to offer thorough therapeutic communication. A miscarriage is very traumatizing, so be sure to ask your patient how best you can support them, what you can do for them.
Some things they may need help with include calling their partner or contacting a family member or friend to come pick them up.
Remember, for the patient, their baby has died, which is deeply personal. This is a time to be extra-mindful of how you communicate with a patient who has just been told that they are experiencing the loss of their pregnancy.
