Your client asks you how you decided that he has a 20% burn. You describe the rule of 9 and ask him to figure the percentage of body area burned from Figure 2. The answer you would expect is

Correct Answer: B

Rationale: The correct answer to the question is option B) 18%. This answer is correct because the Rule of Nines is a commonly used method to estimate the percentage of body surface area that has been burned. According to this rule, the body is divided into different regions, each representing approximately 9% or a multiple of 9% of the total body surface area. In this case, the area represented in Figure 2 corresponds to 18% of the total body surface area, hence the correct answer. Option A) 15% is incorrect because it does not align with the Rule of Nines for the given body area depicted in Figure 2. Option C) 30% and Option D) 36% are also incorrect as they do not correspond to the specific region of the body affected by the burn as per the Rule of Nines. In an educational context, understanding the Rule of Nines is crucial for healthcare professionals, especially in situations where quick assessment of burn injuries is necessary for treatment planning. By knowing how to estimate the percentage of body surface area affected by burns, healthcare providers can make informed decisions regarding fluid resuscitation, wound care, and overall management of the patient. This knowledge is essential in emergency settings where prompt and accurate assessment is critical for patient outcomes.

Correct Answer: B

Rationale: The epidermis of the skin is made of stratified squamous epithelium because it provides protection against abrasion and dehydration. It consists of multiple layers of flat, scale-like cells that constantly shed and regenerate. This type of epithelium is well-suited for the outermost layer of the skin due to its durability and ability to withstand mechanical stress. Simple squamous epithelium (Choice A) is too thin and fragile for the skin's protective function. Cuboidal epithelium (Choice C) is not flat enough to form the outer layer. Transitional epithelium (Choice D) is found in the urinary system, not in the skin.

Correct Answer: C

Rationale: The correct answer is C because stressful situations do not increase the secretions of apocrine glands. Apocrine glands are primarily involved in producing body odor and are not directly influenced by stress. Choices A, B, and D are incorrect. A is false because ceruminous glands are found in the ear canal, not the inner ear. B is false because sebum from sebaceous glands actually helps to lubricate and moisturize the skin. D is false because eccrine glands are simple, coiled tubes that release sweat directly onto the skin surface, not through a duct.

Correct Answer: C

Rationale: Step 1: Topical corticosteroids can lead to local side effects such as skin atrophy and thinning. Step 2: Incorporating this information into the plan of care is crucial to monitor and prevent these adverse effects. Step 3: Choice A is incorrect as applying liberally can increase the risk of side effects. Step 4: Choice B is incorrect as absorption is actually enhanced when skin is moist, not dry. Step 5: Choice D is incorrect as occlusive dressings can increase absorption of corticosteroids, not decrease it.

Correct Answer: A

Rationale: The correct answer is A because a history of burn occurring in an enclosed space can lead to inhalation of toxic fumes causing an inhalation injury. Carbonaceous sputum is associated with smoke inhalation, not egophony or stridor. Egophony is a finding in lung consolidation, and stridor is typically seen in upper airway obstruction.
