Which action would a nurse explain as the next step to take after the flames are extinguished when a person's clothes catch fire?

Correct Answer: B

Rationale: The correct answer is B: Assess the person's breathing. After extinguishing the flames, assessing the person's breathing is crucial as smoke inhalation can cause respiratory issues. It is important to ensure airway patency and adequate oxygenation. Giving sips of water (A) may not be appropriate immediately as the person may have oral burns. Covering with a warm blanket (C) could retain heat and worsen burns. Calculating the extent of burns (D) is important but assessing breathing takes precedence for immediate life-saving measures.

Correct Answer: B

Rationale: The correct answer is B: Epidermis. The integumentary system consists of the skin and its appendages, including the epidermis, which is the outermost layer of the skin. It serves as a protective barrier against external factors. The other choices are incorrect because: A: Myocardium is part of the cardiovascular system, not the integumentary system. C: Lymphatic glands are part of the lymphatic system, responsible for immune function, not the integumentary system. D: Cartilage is a type of connective tissue found in joints and other structures, but it is not a part of the integumentary system.

Correct Answer: D

Rationale: The correct answer is D: Microtubules. Microtubules are a component of the cytoskeleton in human cells, providing structural support, aiding in cell division, and serving as tracks for intracellular transport. They are composed of tubulin protein subunits. A: Golgi complex is responsible for processing and packaging proteins for secretion, not part of the cytoskeleton. B: Cell wall is a rigid structure found in plant cells, not present in human cells. C: Flagella are motile structures used for cell movement, not part of the cytoskeleton. In summary, microtubules are the correct answer as they are a key component of the cytoskeleton, while the other choices are not part of the cytoskeleton in human cells.

Correct Answer: D

Rationale: The correct answer is D because all the other choices mention specific skin diseases that fall under the broader category of common skin diseases. Eczema, psoriasis, acne (A), melanoma, basal cell carcinoma, squamous cell carcinoma (B), and warts, herpes, shingles (C) are all prevalent skin conditions that affect many individuals. By selecting choice D, you encompass all the mentioned skin diseases, providing a comprehensive overview of common skin conditions.

Correct Answer: C

Rationale: The correct answer is C: The distance between the patient and caregivers. This is important in radiation safety as increasing distance reduces radiation exposure. As radiation intensity decreases with distance, keeping a safe distance minimizes the risk of radiation exposure for the nurse. Options A and B are irrelevant to radiation safety. Option D, using a barrier, is not as effective as increasing distance in reducing radiation exposure.
