When assessing an older adult client, the nurse finds that the client is experiencing orthopnea and has an oxygen saturation reading of 93% on room air. Auscultation of the lungs reveals crackles and bilateral pedal edema are present. In which order should the nurse implement these actions? (Arrange in the order from first on top to last on the bottom.)

Rationale:
A. Plan for a follow-up echocardiogram occurring in 4 to 6 weeks: Follow-up echocardiograms are standard to monitor for coronary artery aneurysms, which may develop even after treatment. Early detection is vital to prevent long-term cardiac complications.

B. Resume the toddler's normal immunization schedule: Live vaccines such as MMR and varicella should be delayed for at least 10 months after IVIG, as the therapy can interfere with vaccine efficacy. Non-live vaccines may proceed as scheduled.

C. Irritability and tinnitus are expected for up to 2 weeks: Irritability is common, but tinnitus is not a recognized symptom of Kawasaki disease or its treatment. Persistent symptoms should be reported rather than assumed to be expected.

D. Manage joint pain with a nonsteroidal antiinflammatory: Aspirin, not general NSAIDs, is typically used for inflammation and thrombosis prevention in Kawasaki disease. Use of other NSAIDs may interfere with aspirin’s antiplatelet effects.

Rationale for Correct Choices:

• Rupture: Aneurysm rupture is the most serious and immediate complication of an abdominal aortic aneurysm (AAA). The client’s gnawing back and abdominal pain, along with a pulsatile abdominal mass and bruit, suggest that the aneurysm is unstable.
• Hypertension: Chronic high blood pressure exerts continuous force on arterial walls, weakening the aortic structure and promoting aneurysm formation and progression. It significantly increases the likelihood of rupture once an aneurysm is present.

Rationale for Incorrect Choices:

• Dissection: Dissection involves a tear in the intimal layer of the artery, creating a false lumen. Although serious, it is more commonly associated with thoracic aortic aneurysms rather than abdominal ones. The client's symptoms and findings are more consistent with rupture.
• Occlusion: Aneurysm-related occlusion refers to blockage of blood flow, which is less common in abdominal aneurysms. The client’s peripheral pulses are normal (2+), indicating adequate distal perfusion. There’s no sign of limb ischemia or thrombotic complications.
• Smoking: Smoking is a known risk factor for developing aneurysms but is not the most direct or strongest predictor of rupture. Its role is more associated with aneurysm formation and progression. Hypertension more specifically correlates with increased rupture risk.
• Hyperlipidemia: High lipid levels contribute to atherosclerosis, which can lead to aneurysm development over time. However, like smoking, it is not as strongly associated with aneurysm rupture as hypertension.
