Following delivery of a newborn, the 21-year-old mother is experiencing mild vaginal bleeding. You note that her heart rate has increased from 90 to 120 beats/min and she is diaphoretic. In addition to administering high-flow oxygen, treatment should include:

Correct Answer: A

Rationale: In this scenario, the mother is showing signs of postpartum hemorrhage with increased heart rate, diaphoresis, and mild vaginal bleeding. The correct approach involves treating for shock by addressing hypovolemia and providing uterine massage to help control bleeding. Administering high-flow oxygen is essential. Therefore, the most appropriate option is to treat for shock and perform uterine massage during transport to manage the postpartum hemorrhage effectively.

Correct Answer: D

Rationale: In this scenario, the 4-year-old boy with a tracheostomy tube is showing signs of respiratory distress, including intercostal retractions, a low heart rate, and decreased oxygen saturation. The gurgling sound indicates a possible airway obstruction. Correctly, the immediate action should be to carefully suction the tracheostomy tube. Suctioning can help clear any secretions or obstructions, thus improving the child's ability to breathe effectively. Ventilating through the tube, placing an oxygen mask over it, or removing and cleaning the tube would not address the potential obstruction and could worsen the respiratory distress.

Correct Answer: D

Rationale: The presence of a large contusion over the left upper quadrant of the abdomen, along with signs of shock, points towards a likely injury to the spleen, especially following trauma. The spleen is located in the left upper quadrant of the abdomen and is susceptible to injury due to its position and vulnerability to blunt trauma.

Correct Answer: A

Rationale: Purple and yellow bruises on protected areas like the thighs are concerning as they indicate bruises in various stages of healing, which is a red flag for physical abuse. Bruises on the anterior tibial area or a child clinging to a parent are not specific signs of physical abuse. Siblings watching you is unrelated to the suspicion of physical abuse in this scenario.

Correct Answer: C

Rationale: Inattention to the EMT's presence is a sign of altered mental status in a small child. When a child is not responsive or does not acknowledge the presence of the EMT, it could indicate a change in their mental status. This lack of attention or awareness may signify a neurological issue or other medical condition affecting the child's cognitive function.

Correct Answer: C

Rationale: In a pediatric patient with respiratory distress, a non-rebreathing mask with a flow rate set at 6 to 8 L/min is the most effective way to deliver oxygen. This method ensures a high concentration of oxygen is delivered to the child, aiding in improving oxygen saturation levels. In this scenario, the mother can assist in holding the mask to maintain comfort and cooperation in the child while ensuring proper oxygen delivery.

Correct Answer: B

Rationale: In cases of drowning, it is crucial to assess for a carotid pulse for no more than 10 seconds to determine if chest compressions are needed. This quick assessment helps determine the next steps in providing appropriate care to the patient. Performing chest compressions without confirming the need may not be beneficial and could potentially harm the patient if unnecessary.

Correct Answer: D

Rationale: Systolic blood pressure is the least reliable parameter when assessing perfusion status in a 2-year-old child. In young children, blood pressure measurements can be variable, affected by factors like anxiety or crying. Capillary refill time, presence of peripheral pulses, and skin color and temperature are more reliable indicators of perfusion status in this age group.
