Chapter 30 : Assessment and Management of Patients With Vascular Disorders and Problems of Peripheral Circulation Questions
Question 1 of 5
A nurse on a medical unit is caring for a patient who has been diagnosed with lymphangitis. When reviewing this patients medication administration record, the nurse should anticipate which of the following?
Correct Answer: C
Rationale: Lymphangitis is an acute inflammation of the lymphatic channels caused by an infectious process. Antibiotics are always a component of treatment. Diuretics are of nominal use. Anticoagulants and antiplatelet aggregators are not indicated in this form of infection.
Question 2 of 5
A postsurgical patient has illuminated her call light to inform the nurse of a sudden onset of lower leg pain. On inspection, the nurse observes that the patients left leg is visibly swollen and reddened. What is the nurses most appropriate action?
Correct Answer: B
Rationale: VTE requires prompt medical follow-up. Heparin will not dissolve an established clot. Massaging the patients leg and mobilizing the patient would be contraindicated because they would dislodge the clot, possibly resulting in a pulmonary embolism.
Question 3 of 5
A nurse is closely monitoring a patient who has recently been diagnosed with an abdominal aortic aneurysm. What assessment finding would signal an impending rupture of the patients aneurysm?
Correct Answer: C
Rationale: Signs of impending rupture include severe back or abdominal pain, which may be persistent or intermittent. Impending rupture is not typically signaled by increased blood pressure, bradycardia, cessation of pulsing, or hemoptysis.
Question 4 of 5
The nurse is reviewing the physiological factors that affect a patients cardiovascular health and tissue oxygenation. What is the systemic arteriovenous oxygen difference?
Correct Answer: D
Rationale: The average amount of oxygen removed collectively by all of the body tissues is about 25%. This means that the blood in the vena cava contains about 25% less oxygen than aortic blood. This is known as the systemic arteriovenous oxygen difference. The other answers do not apply.
Question 5 of 5
The nurse is evaluating a patients diagnosis of arterial insufficiency with reference to the adequacy of the patients blood flow. On what physiological variables does adequate blood flow depend?
Correct Answer: A,B,E
Rationale: Adequate blood flow depends on the efficiency of the heart as a pump, the patency and responsiveness of the blood vessels, and the adequacy of circulating blood volume. Adequacy of blood flow does not primarily depend on the size of red cells or their ratio to the number of platelets.
