Questions for Integumentary System Questions
Question 1 of 5
In patients with extensive burns, edema occurs in both burned and unburned areas because of:
Correct Answer: C
Rationale: Capillary permeability is altered in burns beyond the area of tissue damage, resulting in significant shift of proteins, fluid, and electrolytes resulting in edema(third spacing). Catecholamine-induced vasoconstriction does not produce edema. Decreased glomerular filtration may cause fluid retention, but it is not responsible for the extensive edema seen after burn injury. Loss of integument barrier does not cause edema.
Question 2 of 5
The nurse is reviewing the structure and function of the skin with a patient recovering from multiple abrasions. Which should the nurse explain as being classified as a sudoriferous gland?
Correct Answer: B
Rationale: Eccrine glands are sudoriferous (sweat) glands, crucial for thermoregulation.
Question 3 of 5
A young patient is being treated for a femoral fracture suffered in a snowboarding accident. The nurse's most recent assessment reveals that the patient is uncharacteristically confused. What diagnostic test should be performed on this patient?
Correct Answer: C
Rationale: Subtle personality changes, restlessness, irritability, or confusion in a patient who has sustained a fracture are indications for immediate arterial blood gas studies due to the possibility of fat embolism syndrome. This assessment finding does not indicate an immediate need for electrolyte levels, an ECG, or abdominal ultrasound.
Question 4 of 5
A patient was fitted with an arm cast after fracturing her humerus. Twelve hours after the application of the cast, the patient tells the nurse that her arm hurts. Analgesics do not relieve the pain. What would be the most appropriate nursing action?
Correct Answer: A
Rationale: Acute compartment syndrome involves a sudden and severe decrease in blood flow to the tissues distal to an area of injury that results in ischemic necrosis if prompt, decisive intervention does not occur. Removing or bivalving the cast is necessary to relieve pressure. Ordering different analgesics does not address the underlying problem. Encouraging the patient to move the fingers or perform range-of-motion exercises will not treat or prevent compartment syndrome. Petaling the edges of a cast with tape prevents abrasions and skin breakdown, not compartment syndrome.
Question 5 of 5
The nurse notes that a patient's skin is dry, discolored, and easily torn. Which medications should the nurse consider as causing this patient's skin condition?
Correct Answer: A
Rationale: Steroids can cause skin thinning and discoloration.
