A nurse is caring for a client who the provider suspects might have pernicious anemia. The nurse should expect the provider to prescribe which of the following diagnostic tests?

A. Dependent edema: Dependent edema is more commonly associated with right-sided heart failure. In left-sided heart failure, fluid accumulates in the lungs, leading to pulmonary symptoms such as cough and frothy sputum.
B. Jugular distention: Jugular distention is often associated with right-sided heart failure due to impaired blood flow from the right atrium into the right ventricle. It is less likely to be prominent in left-sided heart failure.
C. Nocturnal polyuria: Nocturnal polyuria (increased urination at night) is a common symptom of heart failure, but it is not specific to left-sided heart failure. It can be seen in both left- and right-sided heart failure.
D. Frothy sputum: This is the correct answer. Left-sided heart failure can lead to pulmonary congestion, resulting in the accumulation of fluid in the lungs. Frothy, pink-tinged sputum is a characteristic finding in left-sided heart failure and is often associated with pulmonary edema.

A."I will follow a daily diet high in calories and protein": While maintaining adequate nutrition is important, emphasizing a diet high in calories may not be suitable. A balanced diet, including adequate protein, is recommended.

B."I will avoid getting a flu shot": Individuals with emphysema are at an increased risk of respiratory infections, including influenza. Getting a flu shot is generally recommended to reduce the risk of infection and complications.

C. "I will inhale slowly through pursed lips to help me breathe better."
This statement reflects a correct understanding of a beneficial breathing technique for individuals with emphysema. Inhaling slowly through pursed lips can help create back pressure in the airways, preventing them from collapsing and promoting better air exchange in the lungs. This technique can assist in managing shortness of breath and improving overall respiratory function.

D."I will lie on my stomach to practice abdominal breathing every day": While practicing abdominal breathing can be beneficial, lying on the stomach may not be the most practical or comfortable position for this purpose. The emphasis should be on proper breathing techniques, which can be done in various positions, including sitting or standing.
