During your assessment of a woman in labor, you see the baby's arm protruding from the vagina. The mother tells you that she needs to push. You should:

Correct Answer: D

Rationale: When encountering a protruding limb during delivery, it is crucial to recognize this as an emergency situation. The correct action is to cover the limb with a sterile towel to prevent injury and transport the mother immediately to a medical facility. Attempting to push the limb back into the vagina or trying to manipulate the baby's position can be harmful and delay necessary medical intervention. Encouraging the mother to push and providing high-flow oxygen is not appropriate in this scenario as immediate transport is essential to ensure the safety of both the mother and the baby.

Correct Answer: D

Rationale: In cases of prolapsed umbilical cord, it is crucial to manage the situation promptly. The correct steps include lifting the baby's head off the umbilical cord to reduce pressure, placing the mother in a position that elevates her hips to relieve pressure on the cord, and ensuring that the cord stays moist. Pulling on the cord is not recommended as it can further compromise fetal circulation and should be avoided. Therefore, relieving pressure off the cord by gently pulling on it is not a recommended management approach in cases of prolapsed umbilical cord.

Correct Answer: B

Rationale: The correct compression to ventilation ratio for a single rescuer performing CPR on a child is 30:2. This ratio ensures adequate circulation and oxygenation during CPR. 30 compressions help maintain blood flow, while 2 rescue breaths provide oxygenation. Choice A (3:01) is incorrect as it does not follow the standard CPR guidelines for children. Choice C (15:2) is incorrect as it is the ratio used for adult CPR. Choice D (5:1) is incorrect as it is not the recommended ratio for child CPR.

Correct Answer: D

Rationale: During 2-rescuer child CPR, it is important to compress the chest with one or two hands to a depth equal to one-third the diameter of the chest. This technique ensures effective chest compressions are being delivered to help circulate blood and oxygenate the child's body. Choice A is incorrect because both hands should be used for chest compressions in 2-rescuer CPR. Choice B is incorrect as allowing the chest to fully recoil between compressions is essential to create negative pressure and facilitate blood flow back to the heart. Choice C is incorrect as the standard compression-to-ventilation ratio for child CPR is 30:2, regardless of whether an advanced airway is in place.

Correct Answer: B

Rationale: After a febrile seizure, it is important to offer oxygen and provide transport to a medical facility for further evaluation and management of the underlying cause. Oxygen may be needed in case of hypoxemia resulting from the seizure. Rapidly cooling the child in cold water is not recommended as it may lead to complications such as hypothermia. Keeping the child warm is also not advisable as the priority is to prevent hyperthermia and provide necessary medical intervention by healthcare providers.

Correct Answer: D

Rationale: Capillary refill is a more reliable indicator of perfusion in children than in adults. This is because children have more compliant vessels, making capillary refill a more sensitive indicator of perfusion status in this population. In contrast, while blood pressure, heart rate, and respiratory rate are important indicators, they may not be as reliable in children as capillary refill. Blood pressure can be affected by various factors such as anxiety or pain, heart rate can be influenced by emotions or temperature, and respiratory rate may vary with activity levels. Therefore, capillary refill is preferred in children for a more accurate assessment of perfusion.

Correct Answer: D

Rationale: If a newborn's heart rate is below 60 beats per minute, the appropriate action is to start positive-pressure ventilations. Ventilations help deliver oxygen to the newborn's body and support respiratory function, which is critical in cases of bradycardia. Chest compressions are not recommended until the heart rate is below 60 despite adequate ventilation. Reassessment is essential but not the immediate action required in this scenario. Administering blow-by oxygen alone may not effectively address the underlying cause of bradycardia, making positive-pressure ventilations the priority intervention in this case.

Correct Answer: D

Rationale: During the assessment of a 30-year-old female in labor, the EMT should be aware that delivery is imminent if she is crowning. Crowning indicates that the baby's head is visible at the vaginal opening, signaling that the birth is progressing rapidly and the baby will soon be delivered. This is a critical moment that requires preparedness for the birth process and ensuring a safe delivery environment. Choice A is incorrect because asking the mother when she is expecting to deliver is not relevant when the baby's head is visible at the vaginal opening. Choice B is incorrect as obtaining the patient's medical history is essential for providing appropriate care. Choice C is incorrect because determining the stage of labor by examining the patient is important but recognizing crowning indicates that delivery is imminent and requires immediate action.

Correct Answer: A

Rationale: The most appropriate question to ask when assessing a geriatric patient who may have experienced an acute ischemic stroke is when the symptoms were first noticed. This information is crucial for determining the time window for potential treatments like thrombolytic therapy, as prompt intervention is necessary for stroke management. Option B is not as relevant in the acute assessment of stroke, though important for overall health history. Option C is important but may not be as time-sensitive as determining symptom onset. Option D focuses on a different cardiac event, not directly related to the current concern of a possible stroke.
