NREMT Obstetrics & Gynecology Emergencies 1 — Questions and Answers

Question 1: What is the first stage of labor?

Delivery of the baby.
Dilation of the cervix (Correct answer)
Delivery of the placenta.
Crowning.

Correct answer: Dilation of the cervix

The first stage of labor, known as the dilation stage, is characterized by the onset of regular contractions that cause progressive effacement (thinning) and dilation (opening) of the cervix. This stage is typically the longest and ends when the cervix is fully dilated to 10 centimeters, allowing the baby to pass through.

Question 2: What is a sign of imminent delivery?

Mild, irregular contractions.
Crowning and urge to push (Correct answer)
Minimal pain.
High blood pressure only.

Correct answer: Crowning and urge to push

Crowning, which is the visible appearance of the baby's head at the vaginal opening, is a definitive sign that delivery is imminent and often irreversible. When combined with the mother's uncontrollable urge to push, these indicators signal that the baby is actively descending through the birth canal. This combination means the final stage of labor is underway, requiring immediate preparation for birth.

Question 3: What is the primary concern in a prolapsed umbilical cord?

Excessive maternal bleeding.
Cord compression cutting off baby's oxygen (Correct answer)
Maternal high blood pressure.
Premature rupture of membranes.

Correct answer: Cord compression cutting off baby's oxygen

In a prolapsed umbilical cord, the cord descends before the baby, becoming trapped and compressed between the baby's presenting part and the birth canal. This compression severely restricts or completely cuts off blood flow through the cord, depriving the baby of vital oxygen and nutrients. This is a life-threatening emergency for the baby, demanding immediate intervention to relieve pressure on the cord.

Question 4: What is the priority in postpartum hemorrhage?

Administering oral fluids.
Applying cold packs only.
Controlling bleeding and rapid transport (Correct answer)
Administering pain medications.

Correct answer: Controlling bleeding and rapid transport

Postpartum hemorrhage is a critical medical emergency involving significant blood loss after childbirth, which can rapidly lead to hypovolemic shock and maternal death. The immediate priority is to control the bleeding, often through fundal massage, and ensure rapid transport to a medical facility. Definitive treatment, such as medications or surgical intervention, is required at the hospital.

Question 5: What is an ectopic pregnancy?

Pregnancy in the uterus.
Pregnancy outside the uterus (Correct answer)
Multiple pregnancies.
Molar pregnancy.

Correct answer: Pregnancy outside the uterus

An ectopic pregnancy occurs when a fertilized egg implants outside the main cavity of the uterus, most commonly in one of the fallopian tubes. This condition is life-threatening for the mother because the growing embryo can rupture the fallopian tube, leading to severe internal bleeding. It cannot result in a viable birth and requires immediate medical intervention.

Question 6: What is the recommended position for a pregnant woman with complications?

Supine position.
Left lateral recumbent (Correct answer)
Right side lying.
Prone position.

Correct answer: Left lateral recumbent

Placing a pregnant woman in the left lateral recumbent position (on her left side) helps prevent supine hypotensive syndrome. In the supine position, the gravid uterus can compress the inferior vena cava, reducing venous return to the heart and causing a drop in blood pressure. The left lateral position shifts the uterus off the vena cava, improving blood flow to both the mother and the fetus.

Question 7: What is the priority during delivery in the field?

Apply firm pressure on the uterus.
Support head and ensure airway (Correct answer)
Delay delivery.
Deliver placenta first.

Correct answer: Support head and ensure airway

During a field delivery, once the baby's head emerges, the primary concern is to support it gently to prevent injury and ensure the baby's airway is clear. Gently guiding the head and suctioning the mouth and nose if necessary helps the baby take its first breaths. Establishing a clear airway is crucial for the baby's immediate transition to life outside the womb.

Question 8: What is the normal blood loss during delivery?

100 mL.
250 mL.
500 mL (Correct answer)
1,000 mL.

Correct answer: 500 mL

The normal blood loss during a vaginal delivery is typically considered to be up to 500 mL. While some blood loss is expected, anything exceeding this amount, or 1000 mL for a C-section, is classified as postpartum hemorrhage and requires immediate medical attention. EMS providers must monitor blood loss closely to identify and manage potential complications promptly.

Question 9: What is a sign of preeclampsia?

Low blood pressure.
High blood pressure and swelling (Correct answer)
Frequent urination.
Increased appetite.

Correct answer: High blood pressure and swelling

Preeclampsia is a serious pregnancy complication characterized by new-onset high blood pressure (hypertension) and often protein in the urine after 20 weeks of gestation. Other common signs include significant swelling (edema), especially in the face and hands, and severe headaches. If left untreated, it can progress to eclampsia, which involves seizures and is life-threatening for both mother and baby.
