A nurse is reviewing the laboratory test results for a male client who has an elevated temperature. The nurse should identify which of the following findings is a manifestation of dehydration?

A. Pursed-lip breathing does not require a specific body position, but it is often more comfortable and effective when the patient is in a semi-Fowler’s position (elevated head of the bed) or sitting upright. Being flat on the back might actually make breathing more difficult for some patients with COPD.
B. The technique involves inhaling slowly through the nose and exhaling through pursed lips, which creates a slight resistance during expiration. This helps to keep the airways open longer, reduce airway collapse, and improve oxygen exchange. Proper inhalation and exhalation technique are key components of effective pursed-lip breathing.
C. In pursed-lip breathing, expiration should be longer than inspiration. The recommended pattern is to inhale slowly through the nose for about 2 counts and then exhale slowly through pursed lips for about 4 counts. The extended expiration phase helps to remove trapped air from the lungs and improves overall ventilation.
D. Coughing forcefully is not a part of pursed-lip breathing. Pursed-lip breathing focuses on controlled breathing to improve airflow and ease breathing. Coughing can be done separately if needed, but it is not a component of the pursed-lip breathing technique.

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.
