Final answer:
The red spots that appear on a patient's arm when the tourniquet is applied are a sign that the tourniquet is too tight. The correct option is 1.
Step-by-step explanation:
The red spots that appear on a patient's arm when a tourniquet is applied are likely a sign of petechiae, which are small red or purple spots on the skin resulting from blood leaking out of damaged vessels. This can occur when a tourniquet is too tight and causes damage to the underlying blood vessels.
The technique used during the process of measuring blood pressure or drawing blood includes the application of an inflatable cuff, often at the level of the heart, to temporarily cut off blood flow and measure the pressure required for the blood to begin flowing again or to access veins for blood draw. The correct answer to the student's question is that the red spots indicate the tourniquet is too tight, option (1).
