NURS 3000 MIDTERM QUESTIONS AND 100%
ACCURATE ANSWERS 2024-2025
Types of Burns
Thermal, Chemical, Electrical, Smoke Inhalation
Thermal Burns
Largest Classification of burns caused by fire, radiation, frost bite, water
How long can it take a chemical burn to manifest
up to 72 hours
Primary treatment for chemical burns
water lavages
Types of smoke inhalation injuries
Carbon monoxide poisoning, injury above the glottis, injury below the glottis
What does CO do to oxygen
CO displaces oxygen from hemoglobin
Hypoxia
poor oxygen delivery to brain due to CO poisoning
Carboxyhemoglobinemia
present in blood studies to confirm carbon monoxide poisoning
,Nursing interventions for carbon monoxide poisoning
100% humidified oxygen via non-rebreather mask, monitor Carboxyhemoglobin levels
Signs of CO poisoning
cherry red skin
Signs of injury above the glottis
facial burns, singed facial hair, hoarseness, painful swallowing, oral/nasal membrane
discoloration, carbonaceous sputum
Priority concern of injury above the glottis
Airway, edema may lead to loss of airway and difficulty intubating
How many hours post injury does it take before pulmonary edema occurs after an injury
below the glottis?
Why?
12-24 hours because of fluid shifts from lung injury and increased capillary permeability
What is an injury below the glottis presents as
(ARDS) Acute Respiratory Distress Syndrome
Signs and symptoms of injury below the glottis
crackles, dyspnea, hypoxia
Why is extent of injury hard to determine in electrical burns
most of the tissue damage is beneath the skin (iceberg effect)
, What are patients with electrical burns at risk for
Dysrhythmias due to voltage on heart, compartment syndrome
Myoglobinuria
voltage damages muscle which releases myoglobin which can block renal tubules in
kidneys
Treatment of myoglbinuria
increase urine output 75-100 every hour to prevent renal failure
What needs to be done when moving an electrical burn patient
cervical spine immobilization
3 concerns following electrical burn
myoglobinuria, dysrhythmias, metabolic acidosis
Why can electrical burns cause metabolic acidosis
muscle break down increases lactic acid which can accumulate in the body
Factors indicating severity of burn
depth, extent of total body surface area (TBSA), location, client risk factors
burnt sweat glands
patient will be more susceptible to heat stroke and overheating
