A client is scheduled for a transthoracic echocardiography (TTE). What should the nurse teach the client in anticipation of this diagnostic procedure?

A. Ascending edema:

Ascending edema, also known as dependent edema, is typically associated with right-sided heart failure rather than left-sided heart failure. In right-sided heart failure, the heart's ability to pump blood to the lungs for oxygenation is compromised, leading to fluid backup in the systemic circulation. This fluid accumulates in the dependent areas of the body, such as the lower extremities (legs and ankles), causing swelling that can ascend upwards if left untreated. However, ascending edema is not a characteristic finding in left-sided heart failure, where pulmonary congestion and orthopnea are more common manifestations.

B. The client has no desire to eat:

While decreased appetite can occur in heart failure due to various factors such as fluid retention, abdominal bloating, or medication side effects, it is not a specific hallmark of left-sided heart failure. Symptoms such as fatigue, dyspnea (shortness of breath), orthopnea (difficulty breathing while lying flat), and paroxysmal nocturnal dyspnea (PND) are more commonly associated with left-sided heart failure. These symptoms result from the impaired function of the left ventricle, leading to pulmonary congestion and inadequate oxygenation.

C. The client sleeps on three pillows at night:

This choice is the correct answer. Sleeping on three pillows at night is a classic manifestation of orthopnea, a condition commonly seen in left-sided heart failure. Orthopnea refers to difficulty breathing while lying flat, which is alleviated by elevating the head and upper body with multiple pillows or sleeping in a semi-upright position. Orthopnea occurs due to the redistribution of fluid from the legs and lower body to the lungs when lying down, resulting in pulmonary congestion and respiratory distress.

D. The client has a five-pound weight gain:

Weight gain is a common symptom of fluid retention in heart failure; however, a specific weight gain of five pounds alone may not be indicative of left-sided heart failure without considering other clinical signs and symptoms. In heart failure, weight gain is often associated with fluid overload, which can lead to edema, dyspnea, orthopnea, and other signs of congestion. It's important to assess the client comprehensively for fluid status, including evaluating for edema, respiratory symptoms, and changes in weight over time, to determine the underlying cause of weight gain.

A. Folic acid deficiency anemia:

Folic acid deficiency anemia is characterized by a lack of folate (vitamin B9), which is essential for red blood cell production. Symptoms can include weakness and fatigue, similar to iron-deficiency anemia. However, folic acid deficiency anemia typically does not cause heavy menstrual periods. Laboratory findings may show a low level of folate in the blood, but the hemoglobin level of 8 g/dL and hematocrit level of 28 g/dL alone do not specifically indicate folic acid deficiency anemia without considering other factors like mean corpuscular volume (MCV) and red blood cell indices.

B. Pernicious anemia:

Pernicious anemia is caused by a lack of intrinsic factor, a substance needed for the absorption of vitamin B12. It can lead to symptoms such as weakness and fatigue. However, heavy menstrual periods are not a characteristic feature of pernicious anemia. Laboratory findings may show a low hemoglobin and hematocrit level, but again, other factors such as MCV and vitamin B12 levels would be needed to confirm this type of anemia.

C. Iron-deficiency anemia:

Iron-deficiency anemia occurs due to insufficient iron stores in the body, leading to decreased hemoglobin and hematocrit levels. This type of anemia is commonly associated with symptoms like weakness, fatigue, and heavy menstrual periods in women due to blood loss. The client's hemoglobin level of 8 g/dL and hematocrit level of 28 g/dL are consistent with iron-deficiency anemia, making this the most likely choice based on the information provided.

D. Sickle cell anemia:

Sickle cell anemia is a genetic disorder characterized by abnormal hemoglobin that causes red blood cells to become sickle-shaped and less flexible. It typically presents with symptoms such as anemia, pain crises, and organ damage. However, the client's symptoms of weakness, fatigue, and heavy menstrual periods are not specific to sickle cell anemia. Additionally, sickle cell anemia would have different laboratory findings, including a different pattern on peripheral blood smear and hemoglobin electrophoresis.
