Free Paramedics Medical Emergencies and Obstetrics Questions and Answers

Question 1

You are assisting a home birth for a 32-year-old female in active labor. Upon examination, you discover a pulsating umbilical cord protruding from the vagina ahead of the presenting part. What is the most critical immediate action?

Accepted Answer

Place the patient in a knee-chest or exaggerated Sims' position and manually elevate the presenting fetal part off the cord.

Answer

Umbilical cord prolapse is a true obstetric emergency where the cord is compressed between the presenting part and the maternal pelvis, cutting off oxygen to the fetus. The immediate priority is to relieve this pressure. This is best accomplished by placing the mother in a gravity-dependent position (knee-chest or exaggerated Sims') and using a gloved hand to manually lift the presenting part off the cord. While oxygen and rapid transport are vital, they are secondary to relieving the cord compression.

Question 2

A 28-year-old female who is 36 weeks pregnant is found actively seizing. Her partner reports a recent history of severe headaches, visual disturbances, and significant swelling in her hands and feet. Her blood pressure is 190/110 mmHg. What is the most appropriate medication to treat this patient's condition?

Accepted Answer

Magnesium Sulfate

Answer

This patient is presenting with classic signs and symptoms of eclampsia, which is defined as seizures in a patient with preeclampsia. Magnesium sulfate is the first-line anticonvulsant for both treating active eclamptic seizures and preventing recurrence. While benzodiazepines like diazepam can be used for refractory seizures and labetalol for hypertension, magnesium sulfate is the primary treatment for the underlying cause of the seizures.

Question 3

What is the correct initial dose and route of epinephrine for an adult patient experiencing anaphylaxis with respiratory compromise and hypotension?

Accepted Answer

0.3 to 0.5 mg (1:1,000) intramuscular (IM) injection

Answer

The standard first-line treatment for an adult with anaphylaxis is epinephrine 0.3 to 0.5 mg of the 1:1,000 concentration administered via the intramuscular route, typically into the anterolateral thigh. This route provides rapid absorption. The IV route is typically reserved for patients in or near cardiac arrest or with profound hypotension unresponsive to initial IM injections and fluid resuscitation.

Question 4

You have just assisted with a field delivery. The placenta has delivered, but the mother continues to have heavy, bright red vaginal bleeding. On palpation, her uterine fundus feels soft and "boggy." Which of the following is the most important initial intervention?

Accepted Answer

Perform a firm, vigorous fundal massage.

Answer

The clinical presentation of a soft, boggy uterus combined with heavy postpartum bleeding is indicative of uterine atony, the most common cause of postpartum hemorrhage. The most critical initial intervention is to perform a vigorous fundal massage to stimulate the uterus to contract, which constricts the blood vessels at the placental site and controls the bleeding. Fluid resuscitation is important but secondary to controlling the source of the bleed.

Question 5

You are assessing a 68-year-old patient who presents with the sudden onset of a severe headache described as "the worst headache of my life." This was followed by nausea, vomiting, and nuchal rigidity. Which of the following conditions is most likely?

Accepted Answer

Subarachnoid hemorrhage (SAH)

Answer

The classic presentation of a subarachnoid hemorrhage (SAH) is a sudden, severe "thunderclap" headache, often described by patients as "the worst headache of my life." Associated symptoms like nausea, vomiting, and nuchal rigidity (stiff neck) are due to meningeal irritation from the blood in the subarachnoid space. Ischemic strokes and TIAs typically present with focal neurological deficits rather than a primary complaint of a sudden, maximal headache.
