Calculate Mrs. Hoffman's %UBW and BMI. Does either of these values indicate she is at nutritional risk? How would her 1+ bilateral pitting edema affect evaluation of her weight?
What will be an ideal response?
• Ht. 63"; Admission wt: 119#; UBW (5 years ago) 145-150#; last recorded weight 12 months ago = 139#; %UBW 86% (based on weight 1 year ago)
• BMI: 21.1
- Mrs. Hoffman's BMI is within a healthy range but this alone would not give an accurate view of her weight status.
- The most important risk factor is that she is 86% of her usual body weight, having lost 14% in one year's time.
- Any unexplained weight loss of >10% within a 12-month period places her at nutritional risk.
• Presence of pitting edema indicates her actual (dry) weight is slightly less than her current weight of 119# (suggesting her %UBW is lower than calculated, placing her at a greater nutritional risk).
