Among the options provided, a 4 oz ground beef patty contains the highest amount of zinc, which is beneficial for skin health and aiding the healing of chronic skin ulcers.
Step-by-step explanation:
If a nurse is providing dietary teaching about increased zinc intake for a client with chronic skin ulcers, the best recommendation among the choices given for a food that contains the highest amount of zinc is 4 oz ground beef patty. Seafood, organ meats, nuts, and legumes are among the foods known to be high sources of zinc. In comparison to apple slices, low-fat cottage cheese, and raw spinach, ground beef provides more zinc, which is essential for skin health and wound healing.
