For a female with a height of 5 ft 3 in (63 in), the predicted body weight (PBW) is closest to which value?

Predicted body weight uses a standard height-based estimate to tailor ventilator settings. For females, the Devine formula is PBW = 45.5 kg + 2.3 kg per inch over 5 feet. A height of 63 inches is 3 inches above 5 feet, so add 3 × 2.3 = 6.9 kg to 45.5 kg, giving 52.4 kg. So the predicted body weight is 52.4 kg.
