A nurse is assessing an obese client in the clinic for follow-up after an episode of deep vein thrombosis. The client has lost 20 pounds since the last visit. What action by the nurse is best?

Correct Answer: A

Rationale: The correct answer is A: Ask if the weight loss was intended. This is the best action because unintentional weight loss in an obese client may indicate underlying health issues. By asking if the weight loss was intended, the nurse can assess if there are any concerning factors contributing to the weight loss. Summary of other choices: B: Encouraging a high-protein, high-fiber diet may be beneficial for weight management but does not address the potential underlying causes of weight loss. C: Measuring for new compression stockings is not the priority when assessing unintended weight loss. D: Reviewing a 3-day food diary is important for overall nutrition assessment but does not directly address the reason for the weight loss.

Correct Answer: D

Rationale: The correct answer is D, "All of the above." The colouration of the skin depends on the amount of blood in its blood vessels (A), as blood vessels can give the skin a pink or red hue. The inherent yellowish colour of its tissue (B) also contributes to skin colour, especially in lighter skin tones. Additionally, the amount of melanin in its tissue (C) plays a significant role in determining skin colour, with more melanin leading to darker skin tones. Therefore, all of these factors collectively influence the colouration of the skin, making option D the correct answer.

Correct Answer: A

Rationale: The correct answer is A: Stratum spinosum. The prickle-cell layer is another name for the stratum spinosum. This layer is located between the stratum basale and stratum granulosum in the epidermis. It consists of cells that appear spiny under a microscope due to desmosomes between them. These desmosomes give the cells a prickle-like appearance. The stratum corneum (B) is the outermost layer of the epidermis, composed of dead keratinocytes. The stratum germinativum (C) is another name for the stratum basale, the deepest layer of the epidermis where cell division occurs. Choice D is incorrect as the prickle-cell layer does have a specific name, which is the stratum spinosum.

Correct Answer: A

Rationale: The correct answer is A because sebaceous glands secrete sebum, an oily substance that lubricates the hair and skin, making them waterproof. Sebum also helps protect the skin from drying out and maintains its elasticity. Choice B is incorrect because sebum doesn't make the hair waterproof on its own. Choice C is incorrect because sebum also affects the skin, not just the hair. Choice D is incorrect as sebum plays a crucial role in skin and hair health.

Correct Answer: A

Rationale: The correct answer is A: Rhinoceros. Rhinoceros is the only animal among the options that has sweat glands only on its pinnae (ears). The other choices, Deer, Hippopotamus, and Rabbit, have sweat glands distributed throughout their bodies or in different areas, not just on the pinnae. This unique anatomical feature of the Rhinoceros helps it regulate body temperature by cooling the blood vessels around the ears. Therefore, Rhinoceros is the correct answer based on the specific location of its sweat glands.
