D454 Adult Health III - Set 1 - Part 2

Correct Answer: Notify provider STAT and prepare for emergency surgery

Option a is correct because a ruptured abdominal aortic aneurysm carries ninety percent mortality without emergency surgical intervention, making immediate provider notification and surgical preparation the absolute highest priority action. Option b is incorrect because the patient is already hypotensive with systolic pressure below ninety, so administering an antihypertensive would be dangerous and contraindicated in the setting of hemorrhagic shock from rupture. Option c is incorrect because while positioning may be appropriate in other situations, a ruptured AAA is a surgical emergency requiring immediate resuscitation and operative intervention rather than comfort measures alone. Option d is incorrect because delaying provider notification to obtain laboratory work wastes critical time in a ruptured AAA, where every minute of delay significantly increases mortality from ongoing internal hemorrhage.

Correct Answer: A male over sixty-five with a history of smoking

Option c is correct because screening guidelines recommend routine one-time abdominal aortic aneurysm screening for men over sixty-five with a smoking history, as this demographic carries the highest risk profile. Option a is incorrect because a forty-year-old female, even with hypertension, does not meet the primary screening criteria, as AAAs are far more common in males and typically affect adults over sixty-five years. Option b is incorrect because while being male is a risk factor, a fifty-year-old without smoking history does not meet the established age and risk factor criteria that prioritize screening for older males with tobacco exposure. Option d is incorrect because a thirty-five-year-old male is significantly below the recommended screening age of sixty-five, and family history alone without age and smoking criteria does not meet standard screening guidelines.

Correct Answer: Smoking cessation and surveillance ultrasound every six to twelve months

Option d is correct because aneurysms below five point five centimeters are managed conservatively with smoking cessation as the most important intervention and surveillance ultrasound every six to twelve months to monitor growth. Option a is incorrect because surgical repair is indicated when the aneurysm reaches five point five centimeters or becomes symptomatic, and a four-centimeter aneurysm is managed conservatively with surveillance imaging and risk modification. Option b is incorrect because all diagnosed abdominal aortic aneurysms require regular surveillance monitoring regardless of symptoms, as aneurysms can grow and rupture silently without warning between clinical encounters. Option c is incorrect because chest radiographs do not adequately monitor abdominal aortic aneurysms, and beta-blockers or ACE inhibitors are preferred over calcium channel blockers for blood pressure control in these patients.

Correct Answer: New persistent back pain with increasing abdominal girth and hypotension

Option b is correct because persistent back pain, increasing abdominal girth, and hypotension after endovascular repair strongly suggest an endoleak or graft rupture, which requires immediate provider notification and possible surgical reintervention. Option a is incorrect because mild incisional pain with intact pedal pulses represents expected post-operative findings after endovascular repair and does not indicate any graft complication requiring urgent intervention or escalation. Option c is incorrect because stable vital signs with post-surgical fatigue are normal expected findings in the early post-operative period and do not suggest any complication with the deployed endovascular graft. Option d is incorrect because mild nausea with adequate urine output above thirty milliliters per hour represents reassuring post-operative findings indicating adequate renal perfusion rather than any graft-related complication.

Correct Answer: Limb ischemia from thromboembolism requiring urgent provider notification

Option c is correct because a cold, pale, pulseless extremity after aortic surgery indicates limb ischemia from thromboembolism, which requires urgent provider notification and preparation for possible embolectomy to restore circulation. Option a is incorrect because expected post-operative swelling would not cause a cold, pale, pulseless extremity, and the asymmetry between the two limbs indicates a vascular complication rather than normal surgical recovery. Option b is incorrect because venous insufficiency presents with edema, warmth, and discoloration rather than the cold, pale, pulseless presentation that is characteristic of arterial occlusion and limb-threatening ischemia. Option d is incorrect because the combination of coldness, pallor, and absent pulses in one extremity after aortic surgery represents a serious vascular emergency that cannot be resolved by simple patient repositioning alone.

Correct Answer: As the vessel radius increases wall tension increases proportionally accelerating further dilation

Option a is correct because the Law of Laplace states that as vessel radius increases, wall tension increases proportionally, creating a self-perpetuating cycle where the aneurysm progressively dilates under growing mechanical stress. Option b is incorrect because blood viscosity changes do not directly cause vessel wall thickening in the context of aneurysm formation, and this description does not reflect the Law of Laplace or aneurysm pathophysiology. Option c is incorrect because decreased cardiac output does not cause vessel diameter to shrink in the setting of an aneurysm, and this relationship does not explain the progressive dilation mechanism described by the Law of Laplace. Option d is incorrect because while blood pressure changes affect wall stress, the key principle is that increasing radius drives increasing wall tension regardless of pressure changes, perpetuating the cycle of aneurysm growth.

Correct Answer: Atherosclerosis

Option c is correct because atherosclerosis is the most common underlying cause of abdominal aortic aneurysms, as plaque buildup weakens the vessel wall through chronic inflammation and loss of structural proteins. Option a is incorrect because deep vein thrombosis is a venous condition involving clot formation in the deep veins and does not cause weakening or dilation of the arterial aortic wall leading to aneurysm formation. Option b is incorrect because while vasculitis can rarely affect the aorta, autoimmune vasculitis is not the most common cause of abdominal aortic aneurysms, which are predominantly driven by atherosclerotic disease processes. Option d is incorrect because congenital arteriovenous malformations are structural abnormalities present from birth that involve abnormal connections between arteries and veins, not the acquired degenerative process causing most aneurysms.

Correct Answer: Complete smoking cessation

Option d is correct because smoking cessation is identified as the single most important intervention to slow aneurysm growth, since smoking directly weakens arterial walls and accelerates atherosclerotic plaque formation. Option a is incorrect because while reducing sodium helps control blood pressure, sodium restriction alone does not have the same direct impact on slowing aneurysm growth as smoking cessation, which is the top priority. Option b is incorrect because although regular exercise benefits cardiovascular health, starting a walking program does not directly address the arterial wall damage caused by smoking that is the primary modifiable accelerator of growth. Option c is incorrect because caffeine elimination is not a primary evidence-based recommendation for slowing abdominal aortic aneurysm growth, and its impact is minimal compared to the critical importance of smoking cessation.

Correct Answer: Males over sixty-five years of age

Option b is correct because abdominal aortic aneurysms are far more common in men with a four-to-one male-to-female ratio and typically affect adults over sixty-five years of age, especially those with smoking history. Option a is incorrect because women under fifty have a very low incidence of abdominal aortic aneurysms, as the condition predominantly affects older males and the female-to-male ratio is significantly lower at one-to-four. Option c is incorrect because adolescents are not a target population for abdominal aortic aneurysm screening regardless of family history, as the condition develops over decades of atherosclerotic damage and affects older adults. Option d is incorrect because while older women can develop aneurysms, they are not the highest-risk demographic, as males over sixty-five with smoking history carry the greatest risk and are the primary screening target.

Correct Answer: Connective tissue disorders such as Marfan syndrome

Option a is correct because connective tissue disorders like Marfan syndrome and Ehlers-Danlos syndrome cause structural weakness in blood vessel walls, leading to aneurysm formation at a much younger age than typical patients. Option b is incorrect because autoimmune hepatitis primarily affects the liver parenchyma and does not directly cause the structural weakness in the aortic wall that leads to abdominal aortic aneurysm formation in young patients. Option c is incorrect because metabolic syndrome contributes to atherosclerosis over time but does not explain the early onset of aneurysm in a young patient, which suggests an inheritable structural defect in vessel walls. Option d is incorrect because while chronic kidney disease can cause vascular calcification, it does not explain early-onset aortic aneurysm in a young patient, which more strongly suggests a hereditary connective tissue disorder.

Correct Answer: CT angiography

Option b is correct because CT angiography is the gold standard for pre-surgical planning of abdominal aortic aneurysms, providing detailed information about aneurysm size, anatomy, rupture, dissection, and thrombus formation. Option a is incorrect because plain abdominal radiographs cannot provide the detailed vascular anatomy, thrombus identification, or dissection assessment needed for surgical planning of abdominal aortic aneurysm repair. Option c is incorrect because while Doppler ultrasound is useful for screening and monitoring blood flow, it does not provide the comprehensive anatomical detail that CT angiography offers for pre-surgical planning. Option d is incorrect because standard echocardiography evaluates cardiac structure and function and is not designed to assess the abdominal aorta in sufficient detail for aneurysm surgical planning purposes.

Correct Answer: A stent graft is threaded through the femoral artery into the aneurysm

Option d is correct because endovascular aneurysm repair involves threading a stent graft through the femoral artery and deploying it within the aneurysm, creating a new reinforced channel for blood flow. Option a is incorrect because a large abdominal incision with aortic clamping describes open aneurysm repair, not the minimally invasive endovascular approach that accesses the aorta through the femoral artery. Option b is incorrect because no medication exists that can shrink an aneurysm wall, and the treatment for abdominal aortic aneurysms above the surgical threshold involves either endovascular or open surgical repair. Option c is incorrect because radiation therapy is not used to treat abdominal aortic aneurysms, as the condition requires mechanical reinforcement of the vessel wall through stent grafting or surgical graft placement.

Correct Answer: Five point five centimeters or larger

Option a is correct because the critical surgical threshold for abdominal aortic aneurysm repair is five point five centimeters, above which the risk of rupture rises dramatically and the benefit of repair outweighs surgical risk. Option b is incorrect because two centimeters is below the definition of an aneurysm itself, as an abdominal aortic aneurysm is defined as dilation exceeding three centimeters and surgical repair is not indicated at this size. Option c is incorrect because at three point five centimeters the aneurysm is small and managed conservatively with surveillance imaging and risk factor modification rather than surgical intervention at this stage. Option d is incorrect because waiting until eight centimeters to intervene would expose the patient to extremely high rupture risk, as the established surgical threshold is five point five centimeters for elective repair.

Correct Answer: Open aneurysm repair with aortic clamping and synthetic graft placement

Option c is correct because open aneurysm repair involves a large abdominal incision, clamping the aorta above and below the aneurysm, and surgically placing a synthetic graft to restore vessel integrity. Option a is incorrect because percutaneous balloon angioplasty is used for arterial stenosis and plaque compression, not for repairing a ruptured aortic aneurysm where the vessel wall has catastrophically failed structurally. Option b is incorrect because endovascular coil embolization is a technique used for small vessel aneurysms, particularly intracranial aneurysms, and is not the approach for large ruptured abdominal aortic aneurysms requiring graft repair. Option d is incorrect because catheter-directed thrombolysis dissolves blood clots and does not address the structural failure of the aortic wall in a ruptured aneurysm, which requires surgical graft placement for repair.

Correct Answer: Renal failure from compromised renal artery perfusion

Option d is correct because oliguria below thirty milliliters per hour with rising BUN and creatinine after aortic surgery strongly suggests renal failure from compromised renal artery perfusion during or after the procedure. Option a is incorrect because urinary tract infections present with dysuria, cloudy urine, and fever rather than the oliguria and rising renal function markers that indicate acute renal failure from perfusion compromise. Option b is incorrect because while some post-operative fluid shifting is expected, the combination of oliguria with rising BUN and creatinine specifically indicates renal dysfunction requiring intervention rather than normal recovery. Option c is incorrect because bladder spasms affect urinary comfort and may cause urgency or frequency but do not cause oliguria with elevated renal function markers that indicate acute kidney injury.

Correct Answer: Systolic below one hundred and thirty to reduce aortic wall stress

Option a is correct because the target systolic blood pressure for AAA patients is below one hundred and thirty millimeters of mercury, which reduces mechanical stress on the weakened aortic wall and slows aneurysm progression. Option b is incorrect because targeting systolic pressure below one hundred is excessively aggressive and risks hypotension that could compromise organ perfusion, which is not the recommended approach for AAA blood pressure management. Option c is incorrect because the primary blood pressure target in AAA management focuses on systolic pressure rather than diastolic pressure, and a diastolic goal of below sixty could dangerously compromise coronary artery perfusion. Option d is incorrect because a systolic target below one hundred and sixty is too lenient for AAA management and would allow excessive mechanical stress on the weakened aortic wall, accelerating aneurysm growth and rupture risk.

Correct Answer: Femoral, popliteal, dorsalis pedis, and posterior tibial pulses

Option c is correct because after aortic surgery the nurse must assess all lower extremity pulses bilaterally including femoral, popliteal, dorsalis pedis, and posterior tibial to detect any perfusion compromise or thromboembolism. Option a is incorrect because radial, brachial, and carotid pulses are upper extremity and neck assessments that do not evaluate the lower extremity perfusion most at risk after abdominal aortic aneurysm repair surgery. Option b is incorrect because temporal and apical pulses do not assess lower extremity vascular status, and this combination misses critical distal pulse points needed to detect post-operative limb ischemia after aortic repair. Option d is incorrect because checking only the dorsalis pedis pulse is an incomplete assessment that would miss proximal vascular compromise detectable at the femoral and popliteal levels before distal changes become apparent.

Correct Answer: Blood pressure control and atherosclerotic risk reduction

Option a is correct because beta-blockers and ACE inhibitors control blood pressure to reduce aortic wall stress, while statins and antiplatelets reduce atherosclerotic progression, collectively targeting AAA management goals. Option b is incorrect because metoprolol, lisinopril, atorvastatin, and aspirin are not prescribed for blood glucose regulation or weight management, as their therapeutic targets are blood pressure control and cardiovascular risk reduction. Option c is incorrect because these medications are not primarily prescribed for pain management or acute inflammation reduction in AAA patients, but rather for chronic blood pressure and atherosclerotic disease management. Option d is incorrect because none of the listed medications are antibiotics or immune support agents, as they are cardiovascular medications targeting hypertension and atherosclerosis in abdominal aortic aneurysm management.

Correct Answer: Notify the provider about possible renal perfusion compromise

Option d is correct because sustained urine output below thirty milliliters per hour after aortic surgery suggests possible renal perfusion compromise from surgical complications, and the provider must be notified for further evaluation. Option a is incorrect because two consecutive hours of below-target urine output after aortic repair is not a minor fluctuation but rather a potentially significant indicator of renal compromise that requires prompt clinical escalation. Option b is incorrect because restricting fluids in a post-operative aortic repair patient with declining urine output could worsen renal perfusion and is contraindicated without provider assessment of the underlying cause. Option c is incorrect because independently increasing IV fluid rates without provider direction is outside nursing scope in this clinical context and may mask an underlying complication requiring a different intervention entirely.

Correct Answer: Avoid lifting over ten pounds for six to eight weeks

Option a is correct because post-surgical AAA repair patients should avoid heavy lifting over ten pounds for six to eight weeks to allow the surgical site and graft to heal without excessive intra-abdominal pressure. Option b is incorrect because unrestricted physical activity after aortic repair surgery risks disrupting the graft site and increasing intra-abdominal pressure before adequate healing has occurred during the recovery period. Option c is incorrect because three months of bed rest is excessive and not recommended after AAA repair, as prolonged immobility increases risks of deep vein thrombosis, deconditioning, and other complications of inactivity. Option d is incorrect because resuming all activities within one week is far too aggressive for recovery from aortic surgery and risks serious complications including graft disruption, hemorrhage, and wound dehiscence.
