Many EMS providers learned that a palpable pulse at a specific anatomic location correlates to an estimated systolic blood pressure. Most commonly, providers are taught that a radial pulse means a systolic of at least 90 mm Hg, a femoral pulse 70 mm Hg and a carotid pulse 60 mm Hg.
This assumption was historically taught in certification courses including Advanced Trauma Life Support, but is not supported by peer-reviewed research. The assessment work-around has since been pulled out of most standard curricula, but the practice continues in EMS, likely as one of the all-too-persistent traditions within medicine that hangs around because "we’ve always done it that way".
While not a substitute for a complete blood pressure measurement, a present palpable pulse does inform the EMS provider of a few important conditions. First, a palpable pulse confirms that the patient has a heartbeat and some level of cardiac output. Additionally, presence of a radial pulse can generally infer adequate perfusion to the brain. Finally, comparison of pulse rate and quality between the left and right extremities can assist in identifying a vascular condition like an aortic aneurysm. What a palpable pulse cannot do is infer a systolic blood pressure measurement.

I have! It's basically like using powder. Have you tried a light powder? And honestly even if that doesn't work don't stress, you're gonna look beautiful anyways. School pictures are always awkward and it's no ones best photo so don't let it affect you love
Answer: 2.) 301 miles (3) 30 minutes
Explanation:
2)
Distance traveled per gallon of petrol = 43 miles
Distance traveled on 7 gallons ;
43 × 7 = 301 miles
3)
time taken to cover distance = 45minutes = 45 / 60 = 0.75 hour
Speed of travel = 80km/hr
Recall:
Distance = Speed × time
Distance = 80km/hr × 0.75hr = 60km
Therefore, time required to cover the same distance at 120km/hr equals :
Time = distance / speed
Time = 60km / 120km/hr = 0.5 hr
= 0.5 × 60 = 30 minutes
