Integumentary System Multiple Choice Questions and Answers Questions
Question 1 of 5
A nurse can assess cyanosis in a dark-skinned patient by noting the color of the:
Correct Answer: C
Rationale: The correct answer is C: lips and mucous membranes. In dark-skinned individuals, cyanosis may not be easily visible on the skin. The lips and mucous membranes are often the best areas to assess for cyanosis as they can show a bluish or purple discoloration when there is inadequate oxygenation of the blood. The conjunctiva (Choice A) and sclera (Choice B) may not accurately reflect cyanosis in dark-skinned patients. The soles of the feet (Choice D) are not typically used to assess cyanosis. Therefore, Choice C is the most appropriate option for assessing cyanosis in a dark-skinned patient.
Question 2 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 3 of 5
A client is diagnosed with herpes zoster (shingles). Which pharmacological therapy would the nurse expect to be prescribed to treat this disorder?
Correct Answer: C
Rationale: The correct answer is C: acyclovir (zovirax). Acyclovir is the preferred antiviral medication for treating herpes zoster (shingles) as it inhibits the replication of the virus. It helps to reduce the severity and duration of the outbreak and also decreases the risk of complications. Tetracycline hydrochloride (A) and erythromycin base (B) are antibiotics that are not effective against viruses like herpes zoster. Indomethacin (D) is a nonsteroidal anti-inflammatory drug (NSAID) used for pain relief and inflammation, but it does not treat the underlying viral infection. Therefore, acyclovir is the most appropriate choice for treating herpes zoster due to its specific antiviral action.
Question 4 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 5 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.
