Perspiration is produced by ________ glands.

Correct Answer: D

Rationale: The correct answer is D: merocrine sweat glands. These glands are responsible for producing perspiration, which is a watery fluid that helps regulate body temperature. Merocrine glands release sweat directly onto the skin's surface without losing any cellular components, ensuring efficient cooling. A: Apocrine sweat glands produce a thicker, odorless substance in areas like the armpits and groin. B: Ceruminous glands produce earwax to protect the ear canal. C: Sebaceous glands produce sebum to moisturize the skin and hair. In summary, merocrine sweat glands are the correct choice as they specifically produce perspiration for cooling purposes, distinguishing them from the other gland types mentioned.

Correct Answer: C

Rationale: The correct answer is C: Dendritic cells. Dendritic cells are immune cells found in the epidermis that play a crucial role in initiating immune responses. They capture antigens and present them to T cells, triggering an immune response. Squamous cells (A) are flat cells in the skin, Merkel cells (B) are touch receptors, and Melanocytes (D) produce melanin for skin pigmentation. They are not directly involved in the immune system function within the epidermis.

Correct Answer: B

Rationale: The correct answer is B: rhinophyma. Rhinophyma is characterized by a bulbous nose, hyperplasia of nasal tissues, and is commonly seen in older men with advanced rosacea. Blepharoplasty (A) is eyelid surgery. Nail body (C) refers to the visible part of the nail. Hematoma (D) is a localized collection of blood outside vessels. Rhinophyma aligns with the symptoms described in the question, making it the correct choice.

Correct Answer: A

Rationale: The correct answer is A: Bluish color around the lips and earlobes. This indicates cyanosis, a sign of inadequate oxygenation. Immediate further assessment or intervention is crucial as it suggests potentially severe respiratory or circulatory issues. - Choice B: Yellow skin and sclera indicate jaundice, often a sign of liver dysfunction, which requires attention but is less urgent. - Choice C: Bilateral erythema of the face and neck suggests a possible allergic reaction or skin condition, which is concerning but not immediately life-threatening. - Choice D: Dark brown spotting on the chest and back may indicate skin issues or a benign condition, requiring assessment but not as urgently as cyanosis.

Correct Answer: B

Rationale: The correct answer is B: Irrigate the back and legs with 4 L of sterile normal saline. This intervention is priority as it aims to remove the toxic chemicals from the client's skin, preventing further damage and absorption. Immediate decontamination is crucial in chemical exposure cases to minimize systemic effects. Choice A focuses on fluid resuscitation but is secondary to decontamination. Choice C, obtaining blood for lab tests, can wait until after decontamination. Choice D, documenting the burn surface area, is important but not as urgent as decontamination in this scenario. Prioritizing decontamination will help prevent further harm and improve the client's outcomes.
