Final answer:
The correct pressure application time on an arterial puncture site is around 3 to 5 minutes, depending on several patient-specific factors. Examples using blood flow rates and arterial pressure demonstrate the application of these principles in medical calculations. Option 4.
Step-by-step explanation:
The amount of time that pressure must be applied to the site of an arterial puncture is typically around 3 to 5 minutes for an adult. It is essential to hold pressure for this length of time to ensure that the puncture site closes properly and to prevent excessive bleeding or hematoma formation. However, the exact time can depend on various factors, including the size of the artery punctured, the patient's clotting ability, and whether the patient is on anticoagulant therapy. Option 4.
Now, addressing the specific examples within the provided context illustrates how blood flow and pressure are important concepts in medicine and biology. For instance, given an artery of radius 2 mm with a flow rate of 40 cm/s, you could calculate the flow rate and volume using the formula: Flow Rate (Q) = πr²v. Here, 'r' is the radius of the artery, and 'v' is the velocity of the blood flow. Then to find the volume that passes through the artery in a given period such as 30 seconds, you would multiply the flow rate by the time.
