Integumentary System Questions Questions
Question 1 of 5
What is the laser attracted to in hair removal?
Correct Answer: B
Rationale: The correct answer is B: Melanin. Melanin is the pigment responsible for the color of the hair and skin. Laser hair removal targets melanin in the hair follicles, absorbing the laser energy and converting it to heat, which damages the follicle and inhibits future hair growth. Keratin (A) is a protein in the hair shaft, not the target for laser removal. Collagen (C) is a protein in the skin, not involved in hair removal. Sebum (D) is a natural oil produced by the skin glands, not targeted by laser hair removal.
Question 2 of 5
Nurse Melinda is caring for an elderly bedridden adult. To prevent pressure ulcers, which intervention should the nurse include in the plan of care?
Correct Answer: A
Rationale: The correct answer is A: Post a turning schedule at the client's bedside. Turning the bedridden adult regularly helps redistribute pressure and prevents pressure ulcers. This intervention promotes blood flow and prevents tissue damage. Choice B is incorrect as lotion application does not address the root cause of pressure ulcers. Choice C is incorrect as increasing fluid intake alone does not prevent pressure ulcers. Choice D is incorrect as ring cushions may provide temporary relief but do not address the need for regular repositioning to prevent pressure ulcers.
Question 3 of 5
A client has been taking prednisone (Deltasone) 20 mg once a day to treat severe seborrheic dermatitis. Which of the following assessment findings is of most concern?
Correct Answer: A
Rationale: The correct answer is A: Complaints of epigastric pain. Prednisone can cause gastrointestinal side effects such as stomach irritation, ulcers, or gastritis, which may present as epigastric pain. This is concerning as it can lead to serious complications like gastrointestinal bleeding. Increased appetite (B) and mild weight gain (C) are common side effects of prednisone and are not as concerning as epigastric pain. Improved skin condition (D) is actually a positive outcome of prednisone therapy for seborrheic dermatitis and indicates treatment effectiveness.
Question 4 of 5
A parent calls the pediatric clinic asking for advice on treating lice. The child has already been treated once with lindane(Qwell). Which advice from the nurse is the most appropriate?
Correct Answer: C
Rationale: The correct answer is C because malathion(Ovide) is a recommended alternative treatment for lice when lindane(Qwell) has already been used. Malathion works differently and may be more effective in this case. Choice A is incorrect as lice do not typically survive off the human scalp for long. Choice B is incorrect because using the same treatment multiple times may not be effective. Choice D is incorrect as oral medications are not typically recommended for lice treatment.
Question 5 of 5
The student studying pediatric integumentary problems learns that which are functions of the skin?(Select all that apply.)
Correct Answer: D
Rationale: The correct answer is D: Regulates temperature set point. The skin helps regulate body temperature by dilating or constricting blood vessels and through sweating. This is essential for maintaining homeostasis. A: Assists in water retention - This is incorrect. The skin does not play a significant role in water retention; that is mainly controlled by the kidneys. B: Initiates tactile sensations - While the skin does initiate tactile sensations, it is not listed as a function in this question. C: Provides physical barrier - While the skin does provide a physical barrier, it is not the main function related to the regulation of temperature set point.
