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: C

Rationale: When inserting an oropharyngeal airway in a small child, it is crucial to depress the tongue with a tongue blade and insert the airway with the downward curve facing the tongue. This technique helps in maintaining an open airway and preventing obstruction by the tongue. Placing the airway with the curve facing the roof of the mouth or using a smaller size is not recommended for small children, as it may not effectively keep the airway patent. The tongue-jaw lift maneuver is not the preferred method for inserting an oropharyngeal airway in small children.

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: B

Rationale: When dealing with a suspected case of SIDS, it is crucial to carefully inspect the environment in which the infant was found. This inspection can provide valuable information that may help determine the cause and support further investigation into the incident. By examining the surroundings, potential hazards or clues related to the sudden event may be identified, aiding in understanding the circumstances and potentially preventing similar incidents in the future.

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.
