Integumentary System Multiple Choice Questions and Answers Questions
Question 1 of 5
The nurse differentiates the various types of dermatitis. Which characteristic best describes seborrheic dermatitis?
Correct Answer: C
Rationale: The correct answer is C: Scaly lesions on scalp, ear canals, and eyebrows. Seborrheic dermatitis is a chronic inflammatory skin condition characterized by greasy or dry scaling on areas rich in sebaceous glands like the scalp, ear canals, and eyebrows. This distinguishes it from other types of dermatitis. A: Cell-mediated immunity resulting in inflammatory response - This describes allergic contact dermatitis, not seborrheic dermatitis. B: Erythema and pruritus with scaling associated with phlebitis - This does not accurately describe seborrheic dermatitis. D: Mast cell-stimulated release of histamine - This is characteristic of urticaria, not seborrheic dermatitis.
Question 2 of 5
The nurse preparing to assist the physician to examine the client's skin with a Wood's light would do which of the following?
Correct Answer: B
Rationale: The correct answer is B because informing the client that the procedure is painless helps alleviate anxiety and promotes cooperation. Obtaining informed consent (A) is not necessary for a non-invasive procedure like a Wood's light examination. Shaving the skin site (C) is not required unless necessary for better visualization. Local anesthetic (D) is not needed as the procedure is painless.
Question 3 of 5
A dark-skinned patient has been admitted to the hospital in severe respiratory distress. To determine whether the patient is cyanotic, the nurse will
Correct Answer: C
Rationale: The correct answer is C: check the lips and oral mucous membranes. Cyanosis is characterized by a bluish discoloration of the skin and mucous membranes due to decreased oxygen levels in the blood. Lips and oral mucous membranes are highly vascular and can provide a quick indication of cyanosis. Assessing for a bluish tinge in the sclera (A) may be difficult in dark-skinned individuals. Applying pressure to the palms of the hands (B) does not directly assess for cyanosis. Examining the nailbeds for capillary refill (D) is more related to circulation rather than respiratory distress.
Question 4 of 5
A nurse is working with a patient who has a diagnosis of Cushing syndrome. When completing a physical assessment, the nurse should specifically observe for what integumentary manifestation?
Correct Answer: D
Rationale: The correct answer is D: Hirsutism. In Cushing syndrome, there is excessive production of cortisol which can lead to hirsutism, or abnormal hair growth in women. This is due to the hormonal imbalance caused by the condition. Alopecia (choice A) is not typically associated with Cushing syndrome. Yellowish skin tone (choice B) is more indicative of jaundice or liver problems, not specifically related to Cushing syndrome. Patchy, bronze pigmentation (choice C) is seen in Addison's disease, not Cushing syndrome. Hirsutism is a common manifestation of Cushing syndrome due to the excess cortisol stimulating hair growth, making it the correct choice.
Question 5 of 5
A new patient presents at the clinic and the nurse performs a comprehensive health assessment. The nurse notes that the patients fingernail surfaces are pitted. The nurse should suspect the presence of what health problem?
Correct Answer: C
Rationale: The correct answer is C: Psoriasis. Pitted fingernails are a common finding in psoriasis, a chronic autoimmune skin condition. The pitting occurs due to abnormal growth of the nail matrix cells. In eczema (choice A), there is typically no nail involvement. Systemic lupus erythematosus (choice B) can cause nail changes, but pitting is not a common feature. COPD (choice D) does not directly cause nail pitting. Therefore, based on the presentation of pitted fingernails, psoriasis is the most likely health problem.
