Questions on the Integumentary System Questions
Question 1 of 5
The sensitivity to touch of an area of skin is determined by the:
Correct Answer: C
Rationale: The correct answer is C: number of receptors. Sensitivity to touch is determined by the presence and distribution of sensory receptors in the skin. These receptors detect touch, pressure, temperature, and pain. The more receptors present in an area, the more sensitive it is to touch. Skin thickness (Choice A), number of pores (Choice B), and number of follicles (Choice D) do not directly impact sensitivity to touch, as they are not involved in the detection of tactile stimuli. Therefore, the correct answer is C as it directly relates to the mechanism of touch sensation.
Question 2 of 5
A patient has been using a corticosteroid ointment for several weeks on an inflamed skin region. The nurse should be aware that prolonged use of this medication may result in:
Correct Answer: D
Rationale: The correct answer is D: Thinning and atrophy of the skin. Prolonged use of corticosteroid ointment can lead to skin thinning and atrophy due to its ability to inhibit collagen synthesis and promote breakdown of skin proteins. This can result in fragile, easily bruised skin. Desensitization and nerve damage (Choice A) are not common side effects of corticosteroid ointment. Formation of petechiae (Choice B) is not typically associated with corticosteroid use. Avascularization of the affected skin (Choice C) is not a known consequence of prolonged corticosteroid use.
Question 3 of 5
A patient who was burned at 10:00 AM reports a pre-burn weight of 154 lb (70 kg). The estimated total body surface area (TBSA) burned is 60%. Using the Parkland/Baxter formula, the nurse verifies that the total amount of intravenous lactated Ringer solution to be infused by 6:00 PM on the day of the burn is which of the following?
Correct Answer: C
Rationale: The correct answer is C: 8,400 mL. The Parkland/Baxter formula for fluid resuscitation in burn patients is 4 mL x %TBSA x weight in kg. In this case, it would be 4 mL x 60% x 70 kg = 1,680 mL for the first 8 hours. Since the burn occurred at 10:00 AM, by 6:00 PM, 8 hours have passed. Therefore, the total amount of lactated Ringer solution to be infused by 6:00 PM would be 1,680 mL x 5 = 8,400 mL. Choice A (5,200 mL) is incorrect as it does not take into account the correct formula for fluid resuscitation in burn patients. Choice B (7,470 mL) is incorrect as it is not the total amount of fluid needed based on the Parkland/Baxter formula. Choice D (16,800 mL) is
Question 4 of 5
Which conclusion is made by a nurse who admits a client receiving patient-controlled analgesia (PCA) after surgery?
Correct Answer: A
Rationale: The correct answer is A because administering PCA allows the client to self-administer pain medication within predetermined safety limits, promoting autonomy and timely pain relief. Choice B is incorrect as the amount of medication is preset by healthcare providers to prevent overdose. Choice C is incorrect as PCA involves controlled, consistent dosages. Choice D is incorrect as the nurse still monitors the client's pain levels and response to medication despite self-administration.
Question 5 of 5
Which test would the client undergo to diagnose systemic lupus erythematosus?
Correct Answer: D
Rationale: The correct answer is D, the indirect immunofluorescence test. This test is used to detect autoimmune diseases like systemic lupus erythematosus by analyzing blood samples for specific autoantibodies. It helps identify antibodies that target the body's tissues, a hallmark of lupus. A, the patch test, is used to evaluate allergic dermatitis and photoallergic reactions, not for diagnosing lupus. B, the photo patch test, is specific for identifying allergic reactions to light exposure, not lupus. C, the direct immunofluorescence test is more commonly used to diagnose skin conditions like pemphigus vulgaris, not systemic lupus erythematosus.
