A student nurse asks the RN about the clinical manifestations of a thoracic aortic aneurysm. Which of the following findings should the nurse discuss? (Select all that apply).
Shortness of breath
Difficulty swallowing
Upper chest pain
Diaphoresis
Cough
Hoarseness
Correct Answer : A,B,C,E,F
Choice A: Shortness of breath Shortness of breath can occur with a TAA due to the aneurysm compressing the trachea or the lung tissue. As the aneurysm enlarges, it can impinge on respiratory structures, leading to difficulty in breathing. A thoracic aortic aneurysm (TAA) is a bulging or dilation in the wall of the aorta as it passes through the chest cavity. TAAs can be life-threatening if they rupture or dissect and are often difficult to detect because they tend to grow slowly and usually do not cause symptoms until they become large or rupture.
Choice B: Difficulty swallowing Difficulty swallowing, or dysphagia, may be experienced if a TAA exerts pressure on the esophagus. This can happen when the aneurysm is located in the aortic arch, where the esophagus is in close proximity.
Choice C: Upper chest pain Upper chest pain is a common symptom of TAA and may be described as a deep, steady pain that can radiate to the back, neck, or jaw. The pain is caused by the stretching of the aortic wall and may be a warning sign of an impending rupture.
Choice D: Diaphoresis Diaphoresis, or excessive sweating, is not typically a direct symptom of a TAA. However, it can be associated with acute aortic syndromes, such as aortic dissection or rupture, which are medical emergencies.
Choice E: Cough A persistent cough can be a sign of a TAA, especially if the aneurysm is pressing against the trachea or bronchial tubes. The cough may sometimes produce blood if the aneurysm is causing erosion into these structures.
Choice F: Hoarseness Hoarseness can result from a TAA if the aneurysm compresses the recurrent laryngeal nerve, which controls the muscles of the voice box. This is known as Ortner’s syndrome or cardiovocal syndrome.

Correct Answer is D
Explanation
Choice A reason: Anorexia, or loss of appetite, is not typically a direct manifestation of left-sided heart failure. While it can be associated with many medical conditions and may occur in the context of heart failure due to overall decreased well-being, it is not a specific indicator of left-sided heart failure.
Choice B reason: Weight gain can be associated with heart failure, but it is more commonly a sign of right-sided heart failure, where fluid accumulates in the body tissues, causing swelling and weight increase. In left-sided heart failure, weight gain is not as prominent because the primary issue is the backup of blood into the lungs, not fluid retention in the tissues.
Choice C reason: A distended abdomen can occur in heart failure due to fluid accumulation; however, it is more characteristic of right-sided heart failure, where the failure of the right ventricle leads to systemic congestion, including the abdominal area. In left-sided heart failure, the primary effect is on the lungs, not the abdomen.
Choice D reason: Dyspnea, or difficulty breathing, is a hallmark symptom of left-sided heart failure. It occurs due to the backup of blood in the pulmonary circulation, which leads to pulmonary congestion and reduced oxygen exchange. Patients may experience shortness of breath, especially during exertion or when lying flat (orthopnea), and may wake up at night with shortness of breath (paroxysmal nocturnal dyspnea).
Left-sided heart failure, often caused by conditions like valvular heart disease, leads to a decrease in the heart’s ability to pump blood effectively. This results in a buildup of pressure in the lungs, manifesting as dyspnea, which is an important symptom for nurses and other healthcare providers to recognize and manage promptly.
Correct Answer is D
Explanation
Choice A reason: Hypermagnesemia, or high levels of magnesium in the blood, is not typically associated with refeeding syndrome. Instead, refeeding syndrome can lead to hypomagnesemia, which is a low level of magnesium in the blood, due to shifts of magnesium into the cells during insulin secretion in the refeeding process.
Choice B reason: Hyponatremia, or low levels of sodium in the blood, is not a hallmark of refeeding syndrome. While fluid shifts can affect sodium levels, the key electrolyte disturbances in refeeding syndrome involve phosphorus, potassium, and magnesium.
Choice C reason: Hyperkalemia, or high levels of potassium in the blood, is not a common finding in refeeding syndrome. Similar to magnesium, potassium can shift into cells during refeeding, which can actually lead to hypokalemia, or low levels of potassium in the blood.
Choice D reason: Hypophosphatemia, or low levels of phosphorus in the blood, is the hallmark of refeeding syndrome. When a malnourished individual is refed, insulin secretion is stimulated by the increased carbohydrate intake. Insulin promotes cellular uptake of glucose, which is accompanied by phosphate, potassium, and magnesium, leading to a decrease in the serum levels of these electrolytes. Phosphorus is critical for cellular processes, and its deficiency can lead to muscle weakness, respiratory failure, hemolysis, and impaired cardiac function. During refeeding, careful monitoring of electrolytes is essential to prevent and manage refeeding syndrome. Hypophosphatemia is the most significant laboratory finding to anticipate in a patient with refeeding syndrome, and it requires prompt recognition and treatment to prevent serious complications.
