A nurse is reinforcing teaching with a pediatric client who has had a traumatic leg amputation about phantom limb sensation (PLS). Which of the following statements should the nurse include while reinforcing their teaching?
Phantom limb sensation is caused by irritation and swelling where the amputation was done.
Phantom limb sensation occurs when the bone in the leg continues to grow and damages surrounding tissues.
Phantom limb sensation will make you think you feel your leg even though it is not there.
Phantom limb sensation is most common in children who are born without a leg.
The Correct Answer is C
Choice A rationale
Peripheral nerve damage and inflammatory responses at the surgical site do contribute to the complex nature of post-amputation sensations, but they are not the sole scientific cause of phantom limb sensation. PLS involves a much more intricate neurological process within the central nervous system. Focusing only on local irritation or swelling fails to account for the cortical reorganization that occurs in the brain following the loss of input from the removed anatomical structure.
Choice B rationale
The theory that phantom limb sensation is caused by continued bone growth or tissue damage is scientifically inaccurate. While pediatric patients may experience terminal overgrowth of the residual bone, which can cause localized pain and require revision surgery, this is a distinct clinical entity from PLS. Phantom sensations are primarily a result of the brain's neuroplasticity and the continued activity of the somatosensory cortex that previously mapped the sensory input from the missing limb.
Choice C rationale
This statement accurately describes the physiological phenomenon where the brain continues to receive and interpret signals as if the limb were still attached. The somatosensory cortex maintains a map of the body, and when a limb is removed, the neurons previously responsible for that limb may fire spontaneously or be stimulated by adjacent areas. This neural activity creates a vivid, real perception of the limb's presence, position, or movement despite its physical absence from the body.
Choice D rationale
Phantom limb sensation is actually less common in children with congenital limb deficiencies compared to those who undergo traumatic amputations. For PLS to occur, the brain must have established a functional sensory map of the limb through prior experience and usage. Children born without a limb have not developed the same cortical representation, so they are significantly less likely to experience the sensation of a missing part compared to a child who loses a developed limb.

Correct Answer is C
Explanation
Choice A rationale
Providing baths with antiseptic soap is important for reducing the bacterial load on the skin and preventing wound infection, which is a major complication in burn patients. However, excessive bathing can sometimes lead to chilling or further tissue irritation if the soap is too harsh. While infection control is a pillar of burn management, the systemic physiological demands for tissue regeneration are more effectively met through metabolic and nutritional support than through topical cleansing alone.
Choice B rationale
Administering antipyretics is indicated if the patient develops a fever, which is common during the hypermetabolic state following a severe burn. A normal body temperature is approximately 98.6 degrees Fahrenheit. While managing fever can reduce oxygen consumption and patient discomfort, it does not directly promote the healing of the damaged integument. Antipyretics are a symptomatic treatment rather than a primary intervention for the complex biological process of skin grafting and wound closure.
Choice C rationale
Severe burns trigger a profound hypermetabolic and catabolic response that significantly increases the body's demand for energy and protein. Initiating high-calorie, high-protein nutrition is the priority to prevent muscle wasting and provide the building blocks necessary for collagen synthesis and epithelialization. Without adequate caloric intake, the body enters a negative nitrogen balance, which severely delays wound healing and impairs the immune system's ability to fight off potential opportunistic infections.
Choice D rationale
Encouraging daily physical activity and range of motion exercises is vital for preventing contractures and maintaining joint mobility, especially when burns occur over flexor surfaces. However, physical activity is a rehabilitative goal that follows the initial stabilization and acute healing phases. During the early stages of severe burn injury, the physiological priority is meeting the extreme metabolic needs of the body to ensure that there is enough cellular energy to support tissue repair.
Correct Answer is D
Explanation
Choice A rationale
Pressure injuries typically present as localized areas of tissue necrosis or skin breakdown over bony prominences such as the sacrum or heels. While they can involve inflammation if infected, the classic signs of redness, swelling, and warmth specifically at a surgical incision site are more indicative of a localized inflammatory response to pathogens. Pressure injuries are graded by stages rather than the acute inflammatory symptoms often seen with post-surgical wound complications or cellulitis.
Choice B rationale
Dehydration involves a systemic fluid volume deficit that manifests as poor skin turgor, dry mucous membranes, and concentrated urine. It does not cause localized redness, swelling, or warmth at an incision site. While adequate hydration is essential for the biochemical processes of wound healing, its absence leads to delayed healing or tissue friability rather than the classic signs of inflammation. Normal skin turgor and moist membranes are indicators of a balanced fluid status in patients.
Choice C rationale
Malnutrition, particularly protein-calorie malnutrition or vitamin C deficiency, impairs the synthesis of collagen and slows the inflammatory phase of wound healing. However, it is not a direct cause of acute redness, heat, and swelling at a surgical site. Chronic nutritional deficits may lead to wound dehiscence or delayed closure, but the immediate presence of warmth and edema usually signals an active immune response to a foreign invader or internal injury within the tissue.
Choice D rationale
Infection is the primary hypothesis when a surgical incision displays redness, swelling, and warmth. These are the cardinal signs of inflammation caused by the immune system responding to microbial invasion. Pathogens trigger vasodilation and increased capillary permeability, leading to the heat and edema observed. A normal white blood cell count ranges from 5000 to 10000 mm, and an elevation beyond this range often confirms the nurse's suspicion of a localized or systemic infection.
