6-lug wheels are measured like 4-lug wheels. Bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs.. Note: When measuring a 5-lug wheel the measurement is only an estimate unless accurately measured using a bolt pattern gauge. A bolt pattern gauge is a specialty tool and is not widely available.
Palpation should be done using the fingertips and intensity of the pulse graded on a scale of 0 to 4 +:0 indicating no palpable pulse; 1 + indicating a faint, but detectable pulse; 2 + suggesting a slightly more diminished pulse than normal; 3 + is a normal pulse; and 4 + indicating a bounding pulse.
Keep in mind that you will obtain the most accurate measurement while the child is asleep. Over the first year, the heart rate slows, with a range of 90 to 100 beats per minute up to 2 months of age, 80 to 180 up to 6 months, and 75 to 155 up to 12 months. Toddlers/preschoolers. For this age group, radial pulse measurement is appropriate.
