Integumentary System Exam Questions Questions
Question 1 of 5
Some cells in the subcutaneous tissue produce histamine, which contributes to the process of:
Correct Answer: D
Rationale: The correct answer is D: inflammation. Histamine is released by cells in response to injury or allergens, leading to vasodilation and increased permeability of blood vessels, causing redness and swelling - classic signs of inflammation. Inflammation is a protective response that helps the body to eliminate harmful stimuli and initiate the healing process. Choices A, B, and C are incorrect because histamine does not play a role in infection, mitosis, or energy storage.
Question 2 of 5
The healthcare provider has ordered Collagenase for a patient with a left leg necrotic ulcer. What does the nurse understands about the use of collagenase?
Correct Answer: C
Rationale: The correct answer is C because Collagenase speeds up the rate at which necrotic tissue is removed by breaking down collagen within the necrotic tissue. This enzyme helps to debride the wound and promote healing. Choice A is incorrect as collagenase does not absorb exudates. Choice B is incorrect because collagenase is not the body's own digestive enzymes. Choice D is incorrect because collagenase does not remove exudate through high moisture-vapor transmission rate.
Question 3 of 5
The nurse is caring for a 32-year-old with circumferential full-thickness burns to the right arm and trunk. Which nursing intervention has the highest priority in the plan of care?
Correct Answer: A
Rationale: The correct answer is A: Assess radial pulses several times a day. This is the highest priority because the patient has circumferential full-thickness burns, which can cause compartment syndrome and compromise circulation. Assessing radial pulses helps monitor blood flow to the affected areas. B is incorrect as it's not directly related to the patient's condition. C can potentially cause harm due to the risk of further damaging the burned skin. D is incorrect as removing blisters can increase the risk of infection and delay healing.
Question 4 of 5
Which response would a nurse give to a client who has just had a total hip replacement and states that the plan is to go swimming at the community pool the day after discharge?
Correct Answer: C
Rationale: The correct answer is C because after a total hip replacement, the incision should not be immersed in water until it has completely healed to prevent infection. Immersing the incision in water can increase the risk of complications. Explanation for why the other choices are incorrect: A: While swimming can offer range-of-motion exercises, it is not safe to do so immediately after a total hip replacement surgery. B: Taking a friend along for safety is important, but it does not address the main issue of immersing the incision in water. D: Swimming should not be substituted for prescribed physical therapy as it may not target specific rehabilitation needs post-surgery.
Question 5 of 5
A client with a stage IV pressure ulcer is to receive g of zinc sulfate by mouth. Each tablet contains mg. How many tablets should the nurse administer? Record your answer using a whole number. _2__ tablets (0.22g to mg= 0.22x1000= 220 mg. Order 220/Dose 110 = 2 tablets)
Correct Answer: B
Rationale: The correct answer is B. First, convert 0.22g to mg (0.22 x 1000 = 220 mg). Each tablet contains 110 mg of zinc sulfate. Divide the total dose (220 mg) by the dose per tablet (110 mg) to get the number of tablets needed (220/110 = 2 tablets). Therefore, the nurse should administer 2 tablets to the client. Summary of other choices: A: This choice is incorrect because it does not follow the correct calculation process to determine the number of tablets needed based on the dose per tablet. C: This choice is incorrect as it does not consider the conversion of grams to milligrams and the dose per tablet. D: This choice is incorrect as it does not involve the correct division of the total dose by the dose per tablet to calculate the number of tablets required.
