Which of the following is a risk factor for developing thromboembolism in the post surgical setting?

A. Rinsing the client's mouth helps to remove oral contaminants, ensuring that the sputum specimen is representative of the respiratory secretions.
B. Obtaining the specimen in the evening is not a specific requirement; the best time to collect the specimen is when the client has the most productive cough.
C. Saving the sputum specimen in a clean container is essential to prevent contamination. However, a sterile container is usually required.
D. Collecting the sputum specimen after a meal might induce coughing but can also contaminate the specimen with food particles.

A. Murmurs are usually related to valve dysfunctions, such as tricuspid or pulmonic valve issues, which may or may not be present in right-sided heart failure.
B. Crackles (or rales) are more commonly associated with left-sided heart failure. They result from fluid accumulation in the lungs (pulmonary congestion) due to the heart's inability to handle the blood returning from the lungs.

C. Chest pain can occur in various cardiac conditions but is not a hallmark symptom of right-sided heart failure. It might be present if there are underlying coronary artery disease issues or other conditions, but it is not directly indicative of right-sided heart failure.
D. Peripheral edema is a classic finding in right-sided heart failure. It results from fluid accumulation in the lower extremities due to the heart's inability to effectively pump blood to the lungs and systemic circulation, causing increased venous pressure and fluid leakage into the tissues.
