Final answer:
The traction weight for a SAGAR device on a 64 kg patient with a single femur fracture should be between 1/10th and 1/7th of the patient's body weight, falling within the range of 6.4 kg to 9 kg. The closest answers would be 3 kg to 6 kg or 4 kg to 8 kg, with exact values depending on medical guidelines.
Step-by-step explanation:
The amount of traction to be pulled when using a SAGAR (Swinging and Gliding Apparatus for the Reduction of fractures) for a 64 kg patient with a single femur fracture is generally determined as a percentage of the patient's body weight. For a single femur fracture, the common range of traction weight is approximately 1/10th to 1/7th of the patient's body weight. Therefore, for a 64 kg patient, the traction would be calculated as follows:
Traction weight (kg) = Patient weight (kg) × Percentage of body weight for traction
- 1/10th of 64 kg = 6.4 kg
- 1/7th of 64 kg = 9.14 kg (rounded to 9 kg)
In this case, the probable answer would fall within the B) 3 kg to 6 kg or C) 4 kg to 8 kg range. However, it is essential to follow the specific guidelines or protocols provided by the medical institution or orthopedic surgeon in charge of the treatment.
