A nurse is caring for a patient with heart failure who is receiving a combination of medications, including an ACE inhibitor and a diuretic.
The nurse should monitor for which of the following potential complications?

Choice A rationale

Glucocorticoids like steroids are primarily utilized to suppress active inflammatory processes during acute rheumatic fever episodes rather than serving as a preventive measure for dental procedures. While they reduce systemic inflammation and carditis severity, they do not provide the necessary antimicrobial coverage required to prevent bacterial seeding of damaged heart valves during invasive oral maneuvers. Administering them before dental work would not address the specific risk of bacteremia-induced endocarditis effectively in this client population.

Choice B rationale

Aspirin is a nonsteroidal anti-inflammatory drug used during the acute phase of rheumatic fever to manage joint pain and reduce fever through prostaglandin inhibition. However, aspirin lacks the antibacterial properties required to prevent subacute bacterial endocarditis. Furthermore, its antiplatelet effect might actually increase the risk of bleeding during dental extractions or deep scaling without offering any protection against the pathogens commonly introduced into the bloodstream from the oral cavity during such procedures.

Choice C rationale

Advising a client to avoid all activity is unnecessary and does not address the physiological risk associated with dental work in a patient with a history of rheumatic fever. Activity restriction is usually reserved for the acute phase of the illness to minimize cardiac demand if carditis is present. For a stable client undergoing dental work, the primary concern is the entry of oral bacteria into the circulation, which physical rest cannot prevent or mitigate.

Choice D rationale

Rheumatic fever often causes permanent damage to heart valves, creating a site where bacteria can easily adhere. Dental procedures can introduce oral flora, such as Streptococcus viridans, into the bloodstream. Prophylactic antibiotics are administered to eliminate these bacteria before they can colonize the endocardium or damaged valves. This prevention strategy is the standard of care for high-risk patients to avoid the development of life-threatening infective endocarditis following invasive dental manipulations.

Choice A rationale

Reducing oxygenation would be detrimental to a client with heart failure. The physiological goal is actually to optimize oxygen delivery to the tissues to compensate for the heart's inability to pump effectively. Lowering oxygen levels would exacerbate tissue hypoxia, increase respiratory distress, and worsen the overall clinical status. Management strategies usually involve supplemental oxygen and medications to improve gas exchange rather than reducing the availability of oxygen to the body's vital organs.

Choice B rationale

The primary goal in heart failure management is to reduce the cardiac workload to improve the heart's efficiency. By reducing preload through diuretics and reducing afterload through vasodilators like ACE inhibitors, the heart does not have to work as hard to eject blood. Lifestyle changes and rest also decrease systemic metabolic demands. Reducing the strain on the failing myocardium helps prevent further remodeling, relieves symptoms like dyspnea, and improves the overall quality of life.

Choice C rationale

Reducing cardiac output is the opposite of what is desired in heart failure management. Heart failure is defined by a cardiac output that is insufficient to meet the metabolic needs of the body. Treatment aims to optimize and maintain an adequate cardiac output through various pharmacological and non-pharmacological means. Lowering the output further would lead to organ failure, profound hypotension, and death. Every intervention is designed to make the output more effective and sustainable.

Choice D rationale

Pulmonary efficacy refers to the ability of the lungs to oxygenate blood and remove carbon dioxide. In heart failure, pulmonary efficacy is often compromised by fluid congestion. The goal of medical management is to improve pulmonary efficacy, not reduce it. By clearing fluid from the alveoli using diuretics and improving forward flow, the nurse and physician aim to enhance gas exchange. Reducing pulmonary efficiency would lead to respiratory failure and severe acid-base imbalances.
