Integumentary System Multiple Choice Questions and Answers Questions
Question 1 of 5
Which of the following are goals of fluid resuscitation?
Correct Answer: A
Rationale: Step 1: Fluid resuscitation aims to restore intravascular volume to improve circulation and organ perfusion. Step 2: Intravascular volume restoration helps to maintain blood pressure and tissue oxygenation. Step 3: Weight gain is not the primary goal of fluid resuscitation. Step 4: Fluid resuscitation does not directly reduce bleeding but helps stabilize the patient's condition. Step 5: Normalizing breathing is not a direct goal of fluid resuscitation. Therefore, the correct answer is A, as it aligns with the primary goal of fluid resuscitation.
Question 2 of 5
The nurse plans care for a patient with a newly diagnosed malignant melanoma based on the knowledge that initial treatment may involve (select all that apply)
Correct Answer: B;C
Rationale: The correct answers are B (Mohs' surgery) and C (Surgical excision). Mohs' surgery is used for precise removal of skin cancer layers, ensuring minimal damage to surrounding healthy tissue. Surgical excision involves removing the entire tumor along with a margin of healthy tissue to prevent cancer spread. Shave biopsy (A) is not ideal for melanoma as it may not provide accurate depth information. Localized radiation (D) is not typically used as initial treatment for melanoma, but rather for advanced cases or as adjuvant therapy.
Question 3 of 5
A patient with a contact dermatitis is treated with calamine lotion. What is the rationale for using this base for a topical preparation?
Correct Answer: C
Rationale: The correct answer is C because calamine lotion contains insoluble powders that form a protective barrier on the skin, helping to soothe and protect irritated skin in contact dermatitis. This barrier prevents further irritation and allows the skin to heal. Choice A is incorrect because calamine lotion is not a suspension of oil and water. Choice B is incorrect as calamine lotion is not an emulsion of oil and water. Choice D is incorrect because calamine lotion does not contain a mixture that causes drying when moisture is absorbed.
Question 4 of 5
What is a skin graft that is used to transfer skin and subcutaneous tissue to large areas of deep tissue destruction called?
Correct Answer: A
Rationale: Rationale for Correct Answer (A: Skin flap): 1. A skin flap involves transferring skin and subcutaneous tissue to repair extensive tissue loss. 2. Skin flaps have a direct blood supply, ensuring better survival in large areas of deep tissue destruction. 3. The term "skin graft" usually refers to a procedure where skin is transplanted without its own blood supply. 4. Therefore, a skin flap, with its vascular supply intact, is the appropriate choice. Summary of Incorrect Choices: B: Free graft - Incorrect because free grafts lack a direct blood supply and are more suitable for smaller areas. C: Soft tissue extension - Incorrect as it does not specifically describe the technique of transferring skin and subcutaneous tissue. D: Free graft with vascular anastomoses - Incorrect as this refers to a different technique involving connecting blood vessels, not commonly used for large areas of deep tissue destruction.
Question 5 of 5
A physician is caring for a patient with an infected wound. The physician would expect:
Correct Answer: C
Rationale: The correct answer is C: To leave the wound open. In the case of an infected wound, leaving it open allows for drainage of pus and promotes healing by secondary intention. Closing the wound with sutures (A) can trap bacteria and worsen the infection. Steri strips (B) may not be sufficient to hold the edges together in an infected wound. Covering with a loose dressing (D) can also trap bacteria and hinder healing. Overall, leaving the wound open is the most appropriate approach to manage an infected wound effectively.
