Medical management of cardiac failure uses similar methodology whether it is right-sided or left-sided. Measures such as dietary modification, lifestyle changes, medications to reduce dyspnea and relieve anxiety are implemented.
The primary goal in the medical management of heart failure is to reduce:

Choice A rationale

Elevating the legs is contraindicated for a client with an aneurysm because it can increase venous return and subsequently increase the pressure within the arterial system. For an abdominal or thoracic aneurysm, the goal is to keep systemic blood pressure low and stable to prevent wall stress. Bedrest is often encouraged, but the legs should remain flat or in a neutral position to avoid any unintended increases in central venous or arterial pressures.

Choice B rationale

Administering antihypertensive medications and beta blockers is a standard evidence based intervention for managing aneurysms. These drugs work by lowering the systemic blood pressure and reducing the heart rate, which decreases the force of blood hitting the weakened vessel wall. By minimizing the dP/dt, or the rate of pressure rise, these medications significantly reduce the risk of dissection or rupture. Maintaining a systolic blood pressure within a narrow, low range is the clinical priority.

Choice C rationale

Preventing straining during defecation is crucial because the Valsalva maneuver significantly increases intra abdominal and intra thoracic pressure. This sudden spike in pressure can place excessive stress on the aneurysmal sac, potentially leading to an immediate rupture. Nurses provide stool softeners and educate clients on proper breathing techniques to ensure that they do not hold their breath or exert themselves physically, thereby maintaining a stable and safe internal pressure environment.

Choice D rationale

Psychological stress triggers the sympathetic nervous system, leading to the release of cortisol and adrenaline. These hormones cause vasoconstriction and increase the heart rate and blood pressure, all of which increase the tension on the arterial wall. By maintaining a calm environment and using stress reduction techniques, the nurse helps keep the client's hemodynamics stable. This holistic approach is essential for preventing the physiological spikes that lead to the catastrophic failure of the aneurysm.

Choice A rationale

Transesophageal echocardiography involves the insertion of an ultrasound probe through the esophagus rather than an arterial or venous puncture in the extremities. Monitoring a puncture site and assessing distal pulses are interventions typically reserved for cardiac catheterization or arterial procedures. Because this procedure is endoscopic in nature, there is no peripheral vascular access site created that would require frequent neurovascular checks or monitoring for hematoma formation in the limbs.

Choice B rationale

Assessing for hematuria or melena is not a priority following an esophageal procedure. While internal trauma is a rare risk, these symptoms are more indicative of systemic bleeding or gastrointestinal issues unrelated to the ultrasound probe. The nurse should focus on local complications such as esophageal perforation or aspiration rather than systemic hemorrhage in the urine or stool. Standard laboratory values for hemoglobin are 12 to 16 g/dL for women and 14 to 18 g/dL for men.

Choice C rationale

Positioning the client on the right side to watch for site bleeding is an intervention specific to a liver biopsy, where the weight of the body helps provide pressure to the puncture site. For a client post transesophageal echocardiography, the primary concern is the return of protective airway reflexes. Positioning should facilitate drainage of secretions and prevent aspiration rather than focusing on a non-existent external surgical site or localized pressure on the liver.

Choice D rationale

During this procedure, the throat is numbed with a topical anesthetic to facilitate probe insertion. This suppresses the gag reflex, significantly increasing the risk of aspiration if oral intake occurs too soon. Keeping the head of the bed at 45 degrees promotes lung expansion and prevents secretions from entering the trachea. The nurse must verify the return of the gag reflex by using a tongue blade before allowing any fluids or food.
