10 free EMT practice questions: Obstetric, Neonatal & Gynecologic Emergencies

The newborn is in severe distress and needs immediate resuscitation: Immediate resuscitation is the answer for the opposite picture: an infant who is limp, apneic or gasping, with a heart rate under 100. Heart rate and effective breathing are the two numbers that drive newborn resuscitation, and a vigorously crying infant with good tone is not the one who needs positive-pressure ventilation. Intervening here interrupts a normal transition and delays the drying and warming this baby actually needs.

The newborn requires back blows for airway obstruction: Back blows treat a choking infant, one who cannot cry, cannot cough effectively, and is not moving air. This newborn is crying vigorously, which is direct evidence the airway is open, so the intervention is aimed at a problem that has already been ruled out by the loudest finding in the question. Performing back blows on a healthy newborn is unnecessary force with a real risk of injury.

The newborn should be placed in a cool environment to reduce metabolic demand: Cooling a newborn on scene has no place in field care; therapeutic hypothermia for hypoxic-ischemic encephalopathy is an in-hospital decision made by a neonatal team. Newborns lose heat extremely fast: large surface area, thin insulation, wet skin, and cold stress raises oxygen consumption and worsens acidosis, which is the opposite of reducing metabolic demand. Field care runs the other way: dry the infant, discard the wet linens, cover the head, keep them warm.

Apply firm fundal pressure while continuing gentle downward traction on the head: Fundal pressure is pressure on the top of the uterus, used to help control the uterus in some postpartum situations, and never in a dystocia. Here it drives the fetal body downward into a shoulder that is already wedged against bone, which jams it tighter and adds a risk of uterine rupture. Suprapubic pressure, which is the half of the key paired with hip flexion, is applied low over the pubic bone and pushes the shoulder itself; the two sound similar and do opposite things, which is the confusion this option is built on.

Assist the patient into a standing squat to open the pelvic outlet for delivery: Moving the patient to a squatting or all-fours position genuinely opens the pelvic outlet and is a recognized technique for dystocia. This patient is mid-delivery in the field with a partially delivered infant and a compressed cord, so standing her up costs time, risks a fall, and risks an uncontrolled delivery onto the floor. The key produces the same change in pelvic angle with the patient staying supine and secured, which is why it is the field first line rather than repositioning her upright.

Apply firm, continuous traction to the fetal head to free the impacted shoulder: Firm traction on the head is the instinctive response and the one that causes permanent injury, because the shoulder is against bone, so the force goes into the brachial plexus and produces Erb palsy, and it can injure the cervical spine. The question already tells you gentle traction failed, which is the signal to stop pulling and start changing the pelvis. The key relieves the impaction so the shoulder can pass, while pulling harder only transfers the load onto the infant's neck.

Position the patient supine with legs elevated to maximize cerebral perfusion: Supine with the legs elevated is the reflex for a hypotensive patient, and improving venous return has a legitimate role in some shock presentations, so the instinct is not random. This patient is hypertensive at 172/110, not hypotensive, so there is no perfusion deficit to correct, and laying a 36-week pregnant patient flat on her back adds aortocaval compression that drops the very cardiac output the position was meant to raise. The key achieves better venous return through left lateral positioning without that trade.

Insert a padded bite block between the patient's teeth in case another seizure occurs: Preparing for another seizure is the right instinct: an eclamptic patient may seize again at any moment, and seizure precautions belong in this call. Nothing goes between the teeth to do it: a bite block or any other object in the mouth of a postictal patient can break teeth, obstruct the airway, or provoke vomiting and aspiration, and it offers little protection, since any tongue biting occurs at the onset of the convulsion before a device could be placed. Airway protection here means positioning, suction within reach, and oxygen. The key covers the same risk with left lateral positioning and minimal stimulation, which lowers the chance of the next seizure rather than bracing for it with a hazard.

Delay transport until a full neurologic exam confirms baseline mental status: A thorough neurologic exam is genuinely valuable and it will happen, en route. Waiting on scene for a postictal patient to clear to baseline can take many minutes, and none of that information changes what the EMT can do, because the treatment for eclampsia is not carried on the truck. The key spends those minutes closing distance to magnesium and delivery; this option spends them collecting data that alters nothing.

Suspect uterine atony; perform vigorous fundal massage until bleeding stops: Atony is the most common cause of postpartum hemorrhage, so reaching for fundal massage first is a good habit and the right answer most of the time, which is what makes this the primary trap. The question specifically removes that diagnosis by telling you the fundus is firm and well-contracted, which is what a uterus that is not atonic feels like. Massaging an already-contracted uterus does nothing to a bleeding laceration and causes real maternal pain. The tone of the fundus is the clinching finding, and it has already been handed to you.

Recognize the bleeding as normal lochia; monitor the amount during transport: Some bleeding after delivery is entirely normal, and lochia can look alarming to a family without being dangerous, so not overreacting to postpartum blood is reasonable in principle. Continued brisk bright red bleeding at two minutes with a pulse of 108 is not that. Bright red indicates active bleeding rather than the darker post-delivery discharge, and the rising pulse says the body is already compensating for volume loss. The key acts on evidence of real hemorrhage; this option misclassifies compensated blood loss as expected lochia and downgrades an active bleed to routine observation.

Suspect a birth canal laceration; pack the vagina with dressings to control bleeding: This option reads the pattern correctly and then reaches for the wrong tool. Packing is standard for controlling bleeding at many other sites and looks like the logical way to reach a bleeding birth canal. It is not done in the field: vaginal packing conceals ongoing blood loss so no one can gauge how much is being lost, adds infection risk, and does not reliably compress a laceration in any case. The key applies external pressure where it can be seen and monitored, controlling what it can while keeping the blood loss visible to the receiving team.

Delay treatment until a second blood pressure reading confirms the first result: Repeating a blood pressure before acting is reasonable when one odd reading stands alone in a patient who otherwise looks well: warm dry skin, normal pulse, no obvious source. Here the low number is not isolated: the tachycardia, the pale cool skin, and the boggy uterus all corroborate it. A second cuff reading adds no information you do not already have and costs blood while you take it.

Place the patient in a seated position before treating the vaginal bleeding: Seated positioning is what you use when the patient's problem is work of breathing: pulmonary edema, heart failure, respiratory distress, because sitting up helps them ventilate. This patient's problem is circulating volume, not ventilation mechanics, and sitting a hypotensive patient upright drops cerebral perfusion further. Supine keeps the volume that remains where it is needed.

Administer oxygen only, since the respiratory rate is the most abnormal finding: Oxygen alone would be the answer if oxygenation were the only thing deranged. The respiratory rate of 24 is a compensatory response to hemorrhage, not the primary problem. It is a downstream sign of the shock, not its cause. Giving oxygen while leaving the soft uterus untouched treats the symptom and ignores the bleeding producing it.

Placenta previa: painful bleeding with uterine rigidity, unlike painless abruption: This option names the two conditions correctly and then swaps their features, which is exactly how the trap is built. Previa's signature is painless bright red bleeding with a soft uterus, because nothing is tearing away from the uterine wall to irritate it into rigidity. The question's severe constant pain with a rigid, tender abdomen is abruption's picture, and reversing the pair is the single most common way this pair of conditions gets missed.

The two conditions are clinically identical and cannot be distinguished in the field: Calling them indistinguishable is the honest-sounding option, and it is true that neither can be confirmed without ultrasound. Field differentiation is not the same as diagnosis, though, and the two presentations separate cleanly at the bedside on pain, uterine tone, and blood color, choosing this abandons a pattern the question hands over completely. What the two genuinely share is management: no vaginal exam, left lateral positioning, oxygen, shock care, and rapid transport.

Ectopic pregnancy, since any painful third-trimester bleeding is diagnostic of it: Ectopic pregnancy is right for first-trimester pain with hypotension, typically around 6 to 8 weeks, when a pregnancy implanted outside the uterus ruptures. At 35 weeks the pregnancy is unmistakably intrauterine, so gestational age alone takes this off the table. Both bleed and both cause shock, but the key is the third-trimester cause of painful bleeding, and the date is the one finding that separates them.

Treat as normal labor progression and transport without urgency: Contractions do space out at points in normal labor, so a change in their pattern by itself is not alarming. Sudden complete cessation paired with a tearing sensation, severe pain, pallor, and diaphoresis is not a labor pattern. It is the classic description of the uterus losing its ability to contract because it has torn.

Treat as a placental abruption; expect heavy vaginal bleeding first: Abruption is the other major cause of sudden severe abdominal pain late in pregnancy and belongs on this differential, which makes it the strongest distractor. Waiting for heavy vaginal bleeding to sort them out is the trap: in both conditions the bleeding is frequently concealed inside the abdomen, so its absence rules out neither.

Treat as a precipitous delivery and prepare for imminent birth en route: A sudden change during active labor can mean delivery is imminent, and a prior cesarean does not preclude vaginal birth. Precipitous delivery does not present with a tearing sensation, cessation of contractions, and shock. This patient is bleeding, not delivering.

Tell the patient not to push, place her on her left side, and prepare for immediate transport: Telling a patient not to push and moving immediately is what you do for preterm labor you are trying not to accelerate, or for an abnormal presentation: a prolapsed cord, a breech, a limb. At 37 weeks with a bulging perineum, the urge to push is her uterus and her reflexes finishing the delivery, and no verbal instruction stops that; it just leaves her fighting her own body while the head advances in a moving ambulance. Left lateral positioning is correct for transporting a pregnant patient, but this option leaves out being ready for the delivery already underway.

Have the patient bear down and push with contractions to speed delivery: Coached pushing has a place, in a hospital, with a provider managing the perineum and monitoring the fetus. Actively driving her to push harder to speed things along risks a precipitous delivery, perineal tearing, and a newborn arriving before anyone's hands are in position. The key lets her follow her own urge instead of adding coaching to a process that is already moving fast enough on its own.

Place the patient upright on the edge of the bed to facilitate delivery: The error is choosing the delivery position for her, not the position itself; some patients do deliver upright. Perched on the edge of a bed, a precipitous delivery drops a slippery newborn toward the floor and gives you no control of the head as it emerges. Let her pick what is comfortable and build your setup around that.

The infant is improving; the decreased work of breathing and fading retractions show the distress is resolving: Fewer retractions and a slower rate really are signs of improvement, in an infant whose color, tone, and alertness are improving at the same time. That pairing is what gives them meaning. Here alertness moved the wrong way, and effort dropping while mental status drops is the definition of decompensation. A newborn has very little respiratory reserve, so the interval between tiring and apnea is short.

The infant is fatigued but holding steady; close observation is appropriate, and transport urgency can be reduced: Calling the infant fatigued but holding steady would be fair for a patient whose work of breathing is high while oxygenation and mental status hold firm. You would watch closely and stay ready. Fatigue in a newborn is not a plateau, it is a trajectory toward apnea and then bradycardia, and reducing transport urgency is what does the real damage, because this is the moment to be moving and ventilating.

The infant has settled into periodic breathing, since 30 breaths per minute is within the expected newborn range: A rate of 30 does sit within the textbook newborn range, which is what makes this option tempting, but a number is only normal in context. Periodic breathing belongs to a comfortable infant with normal tone and alertness; this rate belongs to an infant who was laboring minutes ago and is now lethargic and harder to rouse. A falling rate after visible distress is exhaustion, not transition.

Continue observation and stimulation; a heart rate of 110 is adequate and spontaneous breathing should improve: Incorrect. Spontaneous labored gasping is not adequate breathing for a newborn; it is respiratory failure. B is correct because the infant requires ventilation to ensure proper oxygenation. You cannot assume spontaneous efforts will improve.

Apply supplemental oxygen at high flow and observe for spontaneous breathing: Incorrect. Supplemental oxygen alone cannot overcome the inadequate respiratory effort; positive-pressure ventilation is needed to deliver breaths and support the infant's failing spontaneous breathing.

Begin chest compressions immediately; the heart rate is too low despite gasping efforts: Incorrect. Chest compressions are indicated only when the heart rate is below 60 despite adequate oxygenation and ventilation. The HR of 110 is above that threshold; begin ventilation first.
