Integumentary System Questions Questions
Question 1 of 5
On assessment of a child, the nurse notes the presence of white patches on the child's tongue and determines that they may be indicative of candidiasis (thrush). The nurse understands that the white patches of candidiasis (thrush):
Correct Answer: A
Rationale: The correct answer is A because in candidiasis (thrush), the white patches are adherent to the tongue even when scraped with a tongue blade due to the presence of fungal overgrowth. This characteristic distinguishes candidiasis from other conditions. Choices B, C, and D are incorrect because candidiasis does not cause continuous bleeding, a red circle in the center of the lesion, or occur exclusively on the tongue. These features are not consistent with the typical presentation of candidiasis.
Question 2 of 5
Which assessment information documented in a patient's chart indicates that the nurse may need to continue to monitor the skin condition of an 82-year-old patient admitted with bacterial pneumonia?
Correct Answer: B
Rationale: Step 1: Skin moist and intact indicate good skin integrity, important in preventing skin breakdown. Step 2: No skin breakdown noted means there are no existing wounds or pressure injuries. Step 3: History of allergic rashes implies potential for skin irritation or reactions, requiring monitoring. Step 4: Skin warm and dry (Option A) and Skin brown, no skin tenting (Option C) do not indicate skin integrity or risk factors for skin issues. Step 5: Skin pink, no open areas noted (Option D) and Scattered macular brown areas on extremities do not directly suggest skin condition monitoring is needed.
Question 3 of 5
A new patient has come to the dermatology clinic to be assessed for a reddened rash on his abdomen. What diagnostic test would most likely be ordered to identify the causative allergen?
Correct Answer: C
Rationale: The correct answer is C: Patch testing. Patch testing is used to identify contact allergens causing skin reactions, such as rashes. It involves applying small amounts of potential allergens onto the skin and observing for a reaction. This test is ideal for identifying causative allergens in cases of allergic contact dermatitis. A: Skin scrapings are used to diagnose fungal or parasitic infections, not allergens. B: Skin biopsy is used to diagnose skin conditions like skin cancer or inflammatory skin diseases, not allergens. D: Tzanck smear is used to diagnose viral infections like herpes, not allergens.
Question 4 of 5
A nurse is assessing the skin of a patient who has been diagnosed with bacterial cellulitis on the dorsal portion of the great toe. When reviewing the patients health history, the nurse should identify what comorbidity as increasing the patients vulnerability to skin infections?
Correct Answer: D
Rationale: The correct answer is D: Diabetes. Patients with diabetes are more susceptible to skin infections due to compromised immune function, poor circulation, and nerve damage. This increases the risk of developing conditions like bacterial cellulitis. Chronic obstructive pulmonary disease (A) affects the lungs, not directly related to skin infections. Rheumatoid arthritis (B) is an autoimmune condition that primarily affects the joints. Gout (C) is a form of arthritis caused by excess uric acid, not directly linked to increased vulnerability to skin infections.
Question 5 of 5
The nurse is caring for a patient with an electrical injury. The nurse understands that patients with electrical injury are at a high risk for acute kidney injury secondary to:
Correct Answer: D
Rationale: The correct answer is D: release of myoglobin from injured tissues. Electrical injuries can cause muscle damage, leading to the release of myoglobin into the bloodstream, which can cause kidney damage by blocking renal tubules. This can result in acute kidney injury. Other choices are incorrect because hypervolemia from burn resuscitation does not directly lead to acute kidney injury, ureteral stones are not directly related to electrical injuries, and nephrotoxic antibiotics are not typically used solely for prevention of infection in electrical injury cases.
