Lawrence recently attended a local health fair to learn more about improving his diet and lifestyle. while there, a hospital worker used fat calipers on the back of his triceps to assess his percent body fat. a friend points out that skinfold calipers often give very inaccurate percent body fat readings. if lawrence wants to obtain the most accurate percent body fat measurement, which method should he use?
a) dexab) hand-held bioelectrical impedance machinec) underwater weighingd) air displacement

DEXA.

Explanation:

Dual-energy X-ray absorptiometry  is a technique used for the measurement of the mineral bone density. The two different X ray beams of different energy are applied to the patient's bones.

DEXA is used for the accurate measurement of the body fat composition.The fat shadow image of the body is made by the DEXA technique. This gives the measurement of the different fat consumption of the body.

Thus, the correct answer is option (A).

answer: b. complete secondary assessment (detailed physical exam).

after you finished the primary assessment, you must proceed with the assessment by performing a complete detailed physical examination.

this secondary assessment includes a focused on patient’s history, vital signs and a specific and rapid examination of the entire body especially on the injuries acquired from the motor vehicle accident and the patient’s medical complaint.
