A nurse caring for a client with peripheral arterial insufficiency determined the nursing diagnosis of altered peripheral arterial insufficiency. Which intervention will be most appropriate for the client?
Discourage walking in order to limit pain
Encourage extended periods of sitting or standing
Elevate his legs and arms above his heart when resting
Encourage the client to engage in moderate amount of exercise
Dizziness
The Correct Answer is D
A. Discourage walking in order to limit pain: Physical inactivity promotes further vascular stasis and muscle atrophy in the lower extremities. While claudication causes discomfort, complete avoidance of movement prevents the development of collateral circulation. Reduced mobility exacerbates the underlying pathology of arterial insufficiency and impairs long-term functional outcomes.
B. Encourage extended periods of sitting or standing: Prolonged static positioning increases hydrostatic pressure and can worsen peripheral tissue perfusion. Dependency or stasis does not facilitate the arterial inflow required to oxygenate ischemic tissues. Frequent position changes are necessary to prevent localized pressure and maintain adequate circulatory flow.
C. Elevate his legs and arms above his heart when resting: This position hinders gravity-assisted arterial flow to the distal extremities, worsening ischemia. Unlike venous insufficiency, arterial disease requires the limbs to be maintained in a neutral or slightly dependent position. Elevation significantly reduces the perfusion pressure needed to reach peripheral tissues.
D. Encourage the client to engage in moderate amount of exercise: Structured walking programs stimulate the formation of collateral vessels to bypass occluded arteries. Physical activity improves oxygen extraction by the muscles and increases the pain-free walking distance. This intervention remains a cornerstone of conservative management for improving peripheral arterial circulation.

Correct Answer is A
Explanation
A. smoking cessation.: Thromboangiitis obliterans is an inflammatory vascular disease strongly linked to tobacco use. The primary pathophysiological trigger is an autoimmune response to nicotine that leads to segmental vasculitis and digital ischemia. Complete abstinence from all tobacco products is the only effective way to halt the progression of the disease and prevent gangrene or amputation.
B. reduction of alcohol intake.: While excessive ethanol consumption is detrimental to overall cardiovascular health, it is not the primary causative agent for Buerger's disease. Alcohol does not induce the specific segmental inflammation of small and medium-sized arteries seen in this pathology. Smoking cessation remains a far more critical lifestyle modification for these patients.
C. avoiding cold remedies.: Some over-the-counter cold medications contain sympathomimetics that can cause peripheral vasoconstriction. While patients with Raynaud's phenomenon should be cautious, these drugs do not drive the inflammatory process of Buerger's disease. The focus of nursing education must prioritize the elimination of tobacco rather than secondary pharmacological triggers.
D. weight reduction.: Obesity is a significant risk factor for atherosclerosis, but Buerger's disease is a non-atherosclerotic inflammatory condition. While maintaining a healthy body mass index is beneficial for systemic health, it does not stop the specific vasculitis associated with this condition. Tobacco use is the specific modifiable factor that determines the clinical trajectory.
Correct Answer is A
Explanation
A. Apply oxygen, administer morphine, and place the client on bed rest with cardiac monitoring: These interventions prioritize reducing myocardial oxygen demand and alleviating ischemic pain in the acute phase of NSTEMI. Morphine acts as a potent analgesic and vasodilator, while oxygen improves tissue saturation. Bed rest and continuous monitoring ensure hemodynamic stability and rapid detection of dysrhythmias.
B. Have the client chew two aspirin 325 mg each, administer oxygen and bring the crash cart to the bedside: While aspirin is indicated for its antiplatelet effects, a dose of 650 mg exceeds the standard loading dose of 162 to 325 mg. Administering excessive aspirin increases the risk of gastrointestinal hemorrhage without providing additional cardiac benefit. The crash cart is necessary but secondary to immediate pharmacological stabilization.
C. Administer oxygen, give a dose of nitroglycerin sublingual, and follow with a nonsteroidal anti-inflammatory: Nonsteroidal anti-inflammatory drugs, excluding aspirin, are contraindicated in acute myocardial infarction because they increase the risk of myocardial rupture and mortality. Nitroglycerin helps with vasodilation, but the addition of an NSAID is harmful. This combination fails to provide the necessary sedation and potent analgesia required.
D. Begin a heparin drip, administer oxygen, and call the lab for stat troponin levels: Heparin and troponin levels are essential components of NSTEMI management but do not address the client's immediate, unrelieved pain. Anticoagulation prevents further thrombus formation but does not actively reduce the current ischemic workload. Immediate nursing priorities must focus on symptomatic relief and cardiac workload reduction.
