Questions on the Integumentary System Questions
Question 1 of 5
Some people only 'burn' when exposed to the sun. The reason they do not tan is that:
Correct Answer: B
Rationale: The correct answer is B because melanocytes are responsible for producing melanin, the pigment that gives skin its color. If melanocytes are inactive, the skin cannot produce enough melanin to tan, resulting in burning instead. Choice A is incorrect because everyone has the gene for tanning. Choice C is incorrect because keratinocytes are not directly involved in the tanning process. Therefore, the only logical explanation for not tanning and only burning when exposed to the sun is due to inactive melanocytes.
Question 2 of 5
During the acute phase of a burn, the nurse in-charge should assess which of the following?
Correct Answer: A
Rationale: Correct Answer: A: Circulatory status Rationale: 1. Assessment of circulatory status is crucial in the acute phase of a burn to monitor for potential shock. 2. Circulatory status helps determine tissue perfusion and oxygenation. 3. Impaired circulation can lead to further complications and affect overall recovery. Summary of Incorrect Choices: B: Pain level - Important but not the priority in the acute phase. Pain management can be addressed after ensuring circulatory stability. C: Nutritional status - Important for overall healing but not the immediate concern in the acute phase. D: Psychological state - Important for long-term recovery but not the priority in the acute phase when physical stability is crucial.
Question 3 of 5
A male client with psoriasis visits the dermatology clinic. When inspecting the affected areas, the nurse expects to see which type of secondary lesion?
Correct Answer: A
Rationale: The correct answer is A: Scale. In psoriasis, scales are a common secondary lesion due to the rapid turnover of skin cells. The scaling appears as silvery-white plaques on red, inflamed skin. Scales are formed by the accumulation of dead skin cells on the skin surface. Crust (B) forms from dried serum, blood, or pus and is not typically associated with psoriasis. Fissure (C) is a linear crack in the skin that may occur in psoriasis but is not a primary characteristic. Ulcer (D) is a full-thickness loss of skin tissue and is not a typical secondary lesion in psoriasis.
Question 4 of 5
A client is being admitted for the treatment of acute cellulitis of the thigh. The client asks the admitting nurse to explain what cellulitis means. The nurse bases the response on the understanding that the characteristics of cellulitis include:
Correct Answer: C
Rationale: The correct answer is C because cellulitis is a bacterial skin infection that involves the subcutaneous tissue and dermis. When bacteria enter through a break in the skin, it causes redness, swelling, warmth, and pain in the affected area. Choice A is incorrect as cellulitis is not caused by a fungal infection. Choice B is incorrect as cellulitis is not a viral rash. Choice D is incorrect as cellulitis is not a superficial abrasion but rather a deeper skin infection. Therefore, the characteristics of cellulitis align with choice C as it accurately describes the nature of the condition.
Question 5 of 5
A child has been diagnosed with scabies and the parents are taught about the use of 5% permethrin lotion(Elimite). Which statement by the parents indicates the need for further instruction?
Correct Answer: B
Rationale: The correct answer is B. Leaving the lotion on until the next day and giving a bath is incorrect as per the treatment guidelines for scabies. The rationale is that permethrin lotion should be applied on dry skin and left on for 8-14 hours before washing off. This allows the medication to work effectively. Giving a bath right after applying the lotion can wash off the medication prematurely, reducing its efficacy. A: This statement is correct as it describes the correct application of Elimite from the nape of the neck to the toes, except on the genitals. C: This statement is correct as scabies treatment often requires a second application one week after the first to ensure all mites are eradicated. D: This statement is correct as it is recommended to give a warm soapy bath before applying the lotion to clean the skin.
