Final answer:
The secondary survey includes assessment of skin temperature, hemorrhage, breathing, and vital signs, which encompass temperature, heart rate, respiratory rate, and blood pressure.
Step-by-step explanation:
During the secondary survey of a patient, detailed information is collected to form a more complete picture of the patient's current condition. This includes assessing skin temperature, which can provide clues about the circulation and whether the patient is in shock. It also typically includes checking for hemorrhage, which if unnoticed, could lead to serious complications. Breathing is evaluated to determine if the patient has any respiratory issues that may not have been apparent during the primary survey. Lastly, vital signs such as body temperature, heart rate, breathing rate, and blood pressure are measured as they are crucial indicators of the body's basic functions and changes in these can be indicative of disease or injury.
