A nurse is providing education to a client with newly diagnosed type 2 diabetes mellitus. Which statement by the client indicates a need for further teaching?

Choice A rationale
Enlarged liver (hepatomegaly) and peripheral edema are common clinical manifestations of right heart failure (RHF). RHF leads to congestion of systemic circulation, causing fluid accumulation in the liver and peripheral tissues.
Choice B rationale
Crackles in the lungs are more commonly associated with left-sided heart failure, where fluid backs up into the pulmonary circulation, leading to pulmonary edema.
Choice C rationale
A dry hacking cough is not a typical symptom of right heart failure. It is more commonly associated with respiratory conditions such as asthma or bronchitis.
Choice D rationale
Altered mentation with pinpoint pupils is not a characteristic of right heart failure. These symptoms are more indicative of neurological conditions or opioid overdose.

Choice A rationale
Acute respiratory distress syndrome (ARDS) is characterized by severe hypoxemia and respiratory distress, often requiring mechanical ventilation. It is not typically associated with a mild fever and increased respiratory rate.
Choice B rationale
Chronic obstructive pulmonary disease (COPD) is a chronic condition characterized by airflow limitation and respiratory symptoms, but not typically associated with a mild fever.
Choice C rationale
Pulmonary edema involves fluid accumulation in the lungs, leading to respiratory distress and hypoxemia, but not typically associated with a mild fever.
Choice D rationale
Pneumonia is an infection of the lungs causing fever (37.5°C), increased respiratory rate (28 breaths per minute), and other respiratory symptoms. It is the most likely condition given the symptoms.
