Final answer:
In the initial general impression of a patient, a rapid heart rate is not detected as it requires equipment such as a stethoscope or pulse oximeter to measure accurately.
Step-by-step explanation:
During the initial general impression of a patient, you would NOT detect a rapid heart rate. The general impression is based on visuals, sounds, and obvious signs that do not require equipment to assess. You can see cyanosis (a), hear gurgling respirations (b), and notice severe bleeding (c) with your senses during the primary assessment.
However, a rapid heart rate (d) typically requires the use of a device, such as a pulse oximeter or a stethoscope, to be detected accurately.
