Integumentary System Multiple Choice Questions and Answers Questions
Question 1 of 5
A patient with a contact dermatitis is treated with calamine lotion. What is the rationale for using this base for a topical preparation?
Correct Answer: C
Rationale: The correct answer is C because calamine lotion contains insoluble powders that form a protective barrier on the skin, helping to soothe and protect irritated skin in contact dermatitis. This barrier prevents further irritation and allows the skin to heal. Choice A is incorrect because calamine lotion is not a suspension of oil and water. Choice B is incorrect as calamine lotion is not an emulsion of oil and water. Choice D is incorrect because calamine lotion does not contain a mixture that causes drying when moisture is absorbed.
Question 2 of 5
A physician is caring for a patient with an infected wound. The physician would expect:
Correct Answer: C
Rationale: The correct answer is C: To leave the wound open. In the case of an infected wound, leaving it open allows for drainage of pus and promotes healing by secondary intention. Closing the wound with sutures (A) can trap bacteria and worsen the infection. Steri strips (B) may not be sufficient to hold the edges together in an infected wound. Covering with a loose dressing (D) can also trap bacteria and hinder healing. Overall, leaving the wound open is the most appropriate approach to manage an infected wound effectively.
Question 3 of 5
In assessing a patient’s skin it is particularly important to identify any lesions that could be malignant. Which of the following lesions would be suggestive of malignant melanoma?
Correct Answer: B
Rationale: The correct answer is B because a circular, brown-black lesion with elevated, palpable margins is characteristic of malignant melanoma. Melanomas often have irregular borders and colors, and they may be raised. Choice A is more indicative of a vascular lesion. Choice C describes a common mole. Choice D is more typical of a dermatofibroma. In summary, B is the correct choice due to its specific characteristics associated with malignant melanoma, while the other choices describe different types of skin lesions.
Question 4 of 5
Mrs. Reagan has just been treated for basal cell carcinoma of the upper lip by surgical excision. It would be most important to teach her to
Correct Answer: D
Rationale: The correct answer is D: avoid unnecessary exposure to the sun. This is crucial because excessive sun exposure is a major risk factor for developing skin cancers like basal cell carcinoma. By avoiding the sun, Mrs. Reagan can reduce her risk of developing further skin cancers. Observing for recurrence (choice A) is important but not as immediate as sun protection. Systemic chemotherapy (choice B) is not typically used for basal cell carcinoma. While stopping smoking (choice C) is important for overall health, it is not directly related to preventing the recurrence of basal cell carcinoma.
Question 5 of 5
In preparation for his getting out of bed to walk, you are applying an elastic bandage to Mr. Moore’s freshly healed burned leg to provide good venous return and prevent blistering of the new skin. It is most important to
Correct Answer: B
Rationale: The correct answer is B: leave the heel exposed. This is important because when applying an elastic bandage to a freshly healed burned leg, leaving the heel exposed helps to prevent constriction of circulation and allows for proper venous return. By leaving the heel exposed, pressure is not applied directly to the Achilles tendon or the heel area, which could impede circulation and cause discomfort. This also helps to prevent blistering of the new skin by ensuring proper blood flow and reducing the risk of pressure ulcers. Choice A is incorrect because a figure-8 style of wrap may not provide the necessary support and could potentially constrict circulation. Choice C is incorrect because applying the bandage too loosely may not provide the required support and could lead to inadequate compression. Choice D is incorrect because removing the bandage as soon as the patient starts to walk can compromise the healing process and increase the risk of injury.
