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.
When the apical pulse is irregular, it is best to count for at least 1 minute to obtain an accurate rate. 1. Determining an apical pulse involves locating the point of maximal impulse (PMI), placing the bell or diaphragm of your stethoscope at this site, and listening for 1 minute.. To determine the pulse deficit, take the radial and the apical pulses simultaneously. 2. Position the patient either in a supine or a sitting position and expose the patient's sternum and the left side of the chest. 3. Using the appropriate anatomical landmarks, locate the radial and the apical pulses.
