Final answer:
The most likely nutritional deficiency based on the physical assessment findings is vitamin C deficiency.
Step-by-step explanation:
The most likely nutritional deficiency based on the physical assessment findings of poor blood clotting, muscle weakness, and delayed fracture healing is vitamin C deficiency. Vitamin C is essential for collagen formation, which is important for blood clotting, muscle strength, and bone healing. Without enough vitamin C, the capillaries become fragile, leading to hemorrhage, and wound healing is delayed due to a deficiency in collagen formation. Additionally, vitamin C deficiency can cause swollen gums, decayed teeth, and weak bones prone to fracture.
