Chapter 6 Skin and the Integumentary System Practice Questions Quizlet Questions
Question 1 of 5
A patient is diagnosed with atrial fibrillation and the physician orders Coumadin (warfarin). For what skin lesion should the nurse monitor this patient?
Correct Answer: B
Rationale: Ecchymosis refers to a round or irregular macular lesion, which is larger than petechiae. This occurs secondary to blood extravasation. It is important to watch for ecchymosis in a patient receiving any type of anticoagulant.
Question 2 of 5
The nurse understands that negative-pressure wound therapy may be used in the treatment of partial-thickness burn wounds to do which of the following?
Correct Answer: B
Rationale: Negative-pressure wound therapy can be used to treat grafts or partial-thickness burns by decompressing edematous interstitial spaces that enhance local perfusion, optimizing wound healing. This therapy also provides a moist wound-healing environment. The system is closed and may reduce the risk of infection but may not prevent infection. Patients are less mobile because the system needs an electrical source to function. Wound drainage is quantified by using the negative-pressure wound therapy system, but this is not a primary indication for the therapy.
Question 3 of 5
The nurse is noting the texture of a patient's skin and hair. Which secretion should the nurse identify that prevents drying of skin and hair?
Correct Answer: B
Rationale: Sebum, a lipid substance from sebaceous glands, prevents drying of skin and hair and inhibits some bacterial growth.
Question 4 of 5
The patient scheduled for a Syme amputation is concerned about the ability to eventually stand on the amputated extremity. How should the nurse best respond to the patient's concern?
Correct Answer: A
Rationale: Syme amputation (modified ankle disarticulation amputation) is performed most frequently for extensive foot trauma and produces a painless, durable extremity end that can withstand full weight-bearing. Therefore, each of the other teaching statements is incorrect.
Question 5 of 5
A patient has come to the orthopedic clinic for a follow-up appointment 6 weeks after fracturing his ankle. Diagnostic imaging reveals that bone union is not taking place. What factor may have contributed to this complication?
Correct Answer: C
Rationale: Inadequate fracture immobilization can delay or prevent union. A short-term vitamin D deficiency would not likely prevent bone union. VTE is a serious complication but would not be a cause of nonunion. Similarly, bleeding would not likely delay union.
