Patient Data. Select from the choices area to specify which condition the client is most likely experiencing ____, two actions the nurse should take to address that condition ____ and ____, and two parameters the nurse should monitor to assess the client's progress ____ and ____.

The clinical picture strongly points to vitamin C deficiency (scurvy). The client is homeless, eating primarily fast food, which is low in fruits and vegetables — the primary vitamin C sources. Key manifestations include a slow-healing wound despite multiple antibiotic courses, ecchymosis (easy bruising) caused by impaired collagen synthesis and capillary fragility, loose teeth caused by deterioration of connective tissue supporting the gingiva, and nail changes consistent with nutritional deficiency. Blood glucose, hemoglobin, and hematocrit are all within normal limits, ruling out iron-deficiency anemia and uncontrolled diabetes. Vitamin B6 deficiency does not typically produce this constellation of findings. The two most appropriate nursing actions are to advise the client to increase his intake of citrus fruits — a direct dietary source of vitamin C — and to assist the client in finding an appropriate supplement, since his food access is severely limited by homelessness and an oral vitamin C supplement is practical and inexpensive. Having the client count calories or recommending more dairy does not address vitamin C deficiency. Educating about alcohol's effects on nutrition is a lower priority here. For monitoring, dental health is a direct marker of scurvy severity because loose teeth reflect collagen breakdown, and wound healing tracks the effectiveness of vitamin C repletion since ascorbic acid is essential for collagen formation and immune function. Weight and mental status are less specific to vitamin C status in this context.
