Integumentary System Multiple Choice Questions and Answers Questions
Question 1 of 5
A child has been sent to the school nurse with pruritus and honey-colored crusts on the lower lip and chin. The nurse believes these lesions most likely are:
Correct Answer: B
Rationale: The correct answer is B: impetigo. Impetigo is a common bacterial skin infection that often presents with honey-colored crusts. Pruritus, or itching, is also commonly associated with impetigo. Chickenpox (A) typically presents with a rash of red spots that progress to fluid-filled blisters. Shingles (C) is caused by the varicella-zoster virus and presents as a painful rash with blisters in a dermatomal distribution. Herpes simplex type I (D) can cause cold sores, but typically presents as grouped vesicles on the lips rather than crusts.
Question 2 of 5
The nurse is educating a patient with psoriasis. Which information is most important for the nurse to include in the teaching plan?
Correct Answer: B
Rationale: The correct answer is B: Use a humidifier at night. Psoriasis is a chronic skin condition characterized by dry, flaky skin. Using a humidifier at night helps to add moisture to the air, preventing further drying of the skin and reducing irritation. This is crucial in managing psoriasis symptoms. Explanation of why other choices are incorrect: A: Liberally apply a lubricating cream three times daily - While moisturizing is important for managing psoriasis, applying a lubricating cream too frequently may not be necessary and could potentially irritate the skin further. C: Use an alcohol-based cleanser in the morning - Alcohol-based cleansers can be harsh on the skin and may exacerbate psoriasis symptoms by drying out the skin further. D: Take hot baths to reduce skin discomfort - Hot baths can actually worsen psoriasis symptoms by stripping the skin of its natural oils and moisture, leading to further dryness and irritation.
Question 3 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 4 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 5 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.
