Questions for Integumentary System Questions
Question 1 of 5
The nurse notes all these changes in the skin of a 95-year-old patient who is being admitted to an assisted-living facility. Which change will be of most concern to the nurse?
Correct Answer: A
Rationale: Petechiae are caused by pinpoint hemorrhages and are associated with a variety of serious disorders such as meningitis and coagulopathies. The nurse should contact the patient's health care provider about this finding for further diagnostic follow-up. The other skin changes are associated with aging. Although the other changes also will require ongoing monitoring or intervention by the nurse, they do not indicate a need for urgent action.
Question 2 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 3 of 5
A(An)____________________ often produces a superficial cutaneous injury but may cause cardiopulmonary arrest and transient but severe central nervous system deficits.
Correct Answer: B
Rationale: Tissue damage results from the conversion of electrical energy into heat. Monitor the patient for cardiac dysrhythmias.
Question 4 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 5 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.
