A client is diagnosed with a 3-cm abdominal aortic aneurysm (AAA). What would the nurse include in teaching as the best nonsurgical intervention to decrease the risk of rupture of an aneurysm and to slow the rate of enlargement?

A. Allow the client to lie in bed with the lights dim: While a dimly lit environment may reduce general stress, it does not specifically relieve the chest pain associated with acute pericarditis. Comfort measures must target the positional nature of pericardial pain.

B. Provide a neck rub, especially on the left side: A neck rub may offer mild relaxation, but it does not address the underlying pericardial inflammation causing the substernal, radiating pain. This intervention is unlikely to significantly reduce discomfort.

C. Sit the client up with a pillow to lean forward on: Pain from acute pericarditis is often relieved when the client leans forward, as this reduces pressure on the inflamed pericardial surfaces. Sitting upright and leaning forward helps decrease friction between the pericardium and the heart, providing nonpharmacologic relief.

D. Apply an ice pack to the client's chest: Cold application may provide minimal relief for superficial musculoskeletal pain but is generally ineffective for the deep, inflammatory chest pain of pericarditis. It does not reduce pericardial friction or inflammation.

A. Prepare for transcutaneous pacing: Transcutaneous pacing is used to treat symptomatic bradycardia or heart block, which are not primary concerns in hypertrophic cardiomyopathy. HCM typically involves obstruction of ventricular outflow and risk for arrhythmias, but pacing is not a first-line intervention.

B. Instructing the client to start an aerobic exercise plan: Aerobic exercise may increase the risk of sudden cardiac death in clients with HCM due to potential arrhythmias and increased myocardial oxygen demand. Exercise recommendations are usually individualized and often limited rather than broadly prescribed.

C. Instruct the client to perform a Valsalva maneuver: The Valsalva maneuver transiently decreases venous return and can exacerbate left ventricular outflow obstruction in HCM, potentially worsening symptoms. It is generally contraindicated rather than recommended.

D. Preparing for a cardiac catheterization: Cardiac catheterization may be indicated to assess the severity of left ventricular outflow obstruction, measure intracardiac pressures, and evaluate coronary anatomy in HCM. It is a diagnostic intervention that guides treatment planning, making it an anticipated order for newly admitted clients.
