Final answer:
High-protein drinks are recommended for a burn patient losing weight to provide essential substrates for tissue repair and to support the patient's increased metabolic demands.
Step-by-step explanation:
The client who suffered full-thickness burns and is losing weight rapidly should have their dietary needs re-evaluated and adjusted to support wound healing and prevent malnutrition. Given the options provided, the nurse would most likely recommend providing high-protein drinks (option b). Protein is essential for tissue repair, immune function, and the maintenance of lean body mass, all of which are critical for a burn patient's recovery. The body has increased metabolic demands following a burn injury, needing more protein and calories to heal. An increased intake of protein can help mitigate the loss of weight and provide the necessary substrates to repair the damaged tissues. Therefore, focusing on nutrient-rich foods and ensuring adequate calorie intake are fundamental aspects of the dietary adjustments required for this patient.
