Which topical antimicrobial agent is most commonly used for burn wound care due to its broad-spectrum coverage and ability to penetrate eschar?
Answer: Silver sulfadiazine (Silvadene)
Silver sulfadiazine is the most widely used topical agent in burn care due to its broad-spectrum antimicrobial properties and ability to penetrate burn eschar.
A patient with a major burn is receiving morphine for pain control. Which side effect is MOST concerning in a patient with a concurrent inhalation injury?
Answer: Respiratory depression
Respiratory depression is the most dangerous opioid side effect in burn patients with inhalation injuries, as their respiratory function is already compromised.
Mafenide acetate (Sulfamylon) is preferred over silver sulfadiazine in which clinical situation?
Answer: Burns with suspected deep infection requiring eschar penetration
Mafenide acetate penetrates eschar more effectively than silver sulfadiazine, making it the preferred agent when deep infection is suspected or confirmed.
Which medication is used to attenuate the hypermetabolic response in burn patients by blocking catecholamine effects?
Answer: Propranolol
Propranolol, a non-selective beta-blocker, attenuates the hypermetabolic response in burn patients by blocking the effects of excess catecholamines released after major burns.
High-dose intravenous Vitamin C (ascorbic acid) is administered early in major burn resuscitation primarily to:
Answer: Reduce lipid peroxidation and decrease resuscitation fluid requirements
High-dose Vitamin C (66 mg/kg/hr for 24 hours) acts as an antioxidant, reducing free radical-mediated lipid peroxidation and capillary leak, thereby decreasing fluid resuscitation requirements.
Which opioid analgesic is most appropriate for procedural pain (e.g., dressing changes) in burn patients due to its rapid onset and short duration of action?
Answer: Fentanyl
Fentanyl is ideal for procedural pain in burn patients due to its rapid IV onset (1-2 minutes), short duration of action, and high potency, making it effective for painful dressing changes.
Silver nitrate solution used in burn wound care can cause which electrolyte imbalance requiring close monitoring?
Answer: Hyponatremia and hypochloremia
Silver nitrate solution is hypotonic and leaches sodium and chloride from wound tissues, leading to hyponatremia and hypochloremia requiring frequent electrolyte monitoring and replacement.
