What is the difference between a first-degree burn and a second-degree burn?

Correct Answer: D

Rationale: The correct answer is D because it encompasses all the key differences between first-degree and second-degree burns. A: A first-degree burn affects only the epidermis, while a second-degree burn affects both the epidermis and the dermis. This is correct as first-degree burns are superficial, affecting only the outer layer of the skin, while second-degree burns penetrate deeper into the dermis. B: A first-degree burn is characterized by redness and pain, while a second-degree burn is characterized by blisters and swelling. This is accurate as first-degree burns typically result in redness and pain, whereas second-degree burns involve blister formation and swelling due to damage to deeper skin layers. C: A first-degree burn heals within a few days, while a second-degree burn may take several weeks to heal. This is true as first-degree burns are minor and usually heal quickly, whereas second-degree burns require more time to heal due to the deeper tissue damage. Therefore, by considering all the distinctions

Correct Answer: A

Rationale: The correct answer is A: Assess the client's lung sounds and oxygenation. This is the most appropriate action because Lisinopril, an ACE inhibitor, can cause a side effect of cough due to bradykinin accumulation in the lungs. This cough can indicate potential pulmonary edema or bronchospasm. Assessing lung sounds and oxygenation can help determine the severity of the cough and any respiratory distress. It is crucial to evaluate the client's respiratory status promptly to prevent further complications. Summary of other choices: B: Instructing the client on another antihypertensive is not appropriate without assessing the current situation. C: Obtaining vital signs is important but assessing the respiratory status takes precedence due to potential respiratory distress. D: Reminding the client about the side effect of Prinivil is not sufficient; the focus should be on evaluating the current cough and its impact on the client's respiratory status.

Correct Answer: C

Rationale: The correct answer is C: Epidermis. Arterioles are small blood vessels that supply oxygen and nutrients to tissues. The epidermis is the outermost layer of the skin and does not contain blood vessels. Therefore, arterioles do not pierce through the epidermis. The dermis (choice A) and subcutaneous layer (choice B) both contain blood vessels, so arterioles do pierce through them. Muscles (choice D) are not part of the skin layers, so arterioles do not pierce through muscles either. In summary, the epidermis is the only skin layer that is not pierced by arterioles because it lacks blood vessels.

Correct Answer: A

Rationale: The correct answer is A: Stratum germinativum. Active mitosis takes place in the stratum germinativum, also known as the basal layer of the epidermis. This layer contains actively dividing cells responsible for skin regeneration. The other choices, B: Stratum granulosum, C: Stratum lucidum, and D: Stratum corneum, are layers of the epidermis where cells are not actively dividing but rather undergoing differentiation and maturation. Therefore, they do not host active mitosis.

Correct Answer: A

Rationale: The correct answer is A because the skin of a rabbit is typically dry, thin, soft, and hairy. Rabbits have delicate skin with a thin layer of fur, making it soft to the touch. The hair on the skin provides insulation and protection. Choice B is incorrect because rabbit skin is not typically hairless. Choices C and D are incorrect as rabbit skin is not thick or hard; it is known for its thin and delicate nature.
