Which of the following are types of burns? Select All That Apply.

Rationale:

A. Regulate red blood cell production in the bone marrow is incorrect. Red blood cell production, or erythropoiesis, is controlled by erythropoietin, a hormone secreted primarily by the kidneys in response to low oxygen levels. Goblet cells have no role in this process. They are epithelial cells specialized for mucus secretion, not involved in hematopoiesis or the regulation of blood cell production.

B. Secrete mucus to trap dust and particles in the nasal cavity is correct. Goblet cells are unicellular glands located within the epithelial lining of the respiratory and gastrointestinal tracts. Their main function is to produce mucus, a sticky secretion that traps dust, microbes, and other particles, preventing them from reaching delicate tissues. In the respiratory system, mucus works together with cilia in a process called the mucociliary escalator, which moves trapped particles upward and out of the airways to maintain pulmonary health. Goblet cells also help moisturize mucosal surfaces, protecting them from drying and injury.

C. Produce antibodies to fight infections is incorrect. Antibodies are proteins produced by B lymphocytes and plasma cells as part of the adaptive immune system. Goblet cells do not have the machinery to produce immunoglobulins or participate in specific immune responses. While mucus does provide some nonspecific immune protection by trapping pathogens, it is not involved in antibody production.

D. Generate platelets for blood clotting is incorrect. Platelets are fragments of cytoplasm derived from megakaryocytes in the bone marrow and play a critical role in hemostasis. Goblet cells are unrelated to the clotting system and do not contribute to platelet formation or blood coagulation.

Rationale:

A. Inhalation injury is a serious complication of severe burns, especially those involving the face, neck, or upper torso, or occurring in a fire with smoke or toxic fumes. Thermal or chemical injury to the respiratory tract can cause airway edema, bronchospasm, and impaired gas exchange, which can be life-threatening if not promptly managed.

B. Contractures can develop during the healing process of deep partial-thickness or full-thickness burns. Scar tissue and skin grafts can limit joint mobility, leading to permanent deformities if proper positioning, physical therapy, and splinting are not implemented.

C. Hypovolemic shock is a common early complication of severe burns. Extensive burn injuries cause massive fluid loss through damaged skin and increased capillary permeability, leading to decreased circulating blood volume, hypotension, and organ hypoperfusion. Immediate fluid resuscitation is critical to prevent shock and organ failure.

D. Hearing loss is not a recognized complication of burn injuries. Burns typically do not affect the auditory system unless there is a direct traumatic injury to the ears, which is rare.

E. Increased muscle mass is incorrect. Severe burns are associated with catabolism, muscle wasting, and negative nitrogen balance due to hypermetabolic stress, not increased muscle mass.

F. Infection is a major risk in burn patients because the skin barrier is destroyed, providing a portal for bacteria, fungi, and viruses. Burn wounds are highly susceptible to local infections and sepsis, which is a leading cause of morbidity and mortality in severe burn injuries.
