A client with congestive heart failure presents with a dry, persistent cough. The nurse should recognize this symptom as:

A) This choice is incorrect because while electrolyte imbalances can have cardiovascular implications, they are not directly associated with diabetes mellitus or congestive heart failure.

B) This choice is incorrect because left-sided heart failure is not directly related to uncontrolled diabetes mellitus. However, diabetes can exacerbate heart failure if not well-controlled due to its impact on blood vessels and the heart.

C) This choice is incorrect because decreased afterload is not directly related to uncontrolled diabetes mellitus. Afterload refers to the resistance the heart has to overcome to eject blood into the circulation.

D) This choice is correct. Uncontrolled diabetes mellitus can lead to microvascular damage, particularly in the small blood vessels of the heart. This damage can contribute to heart muscle dysfunction and congestive heart failure. Diabetes is a significant risk factor for developing heart failure.

Questions

A) This choice is incorrect because consuming a diet high in sodium would exacerbate fluid retention in congestive heart failure. Clients with CHF should follow a low-sodium diet to reduce fluid overload and manage edema.

B) This choice is incorrect because limiting fluid intake to 1 liter per day is too restrictive and may lead to dehydration. Fluid restriction is essential for some clients with CHF, but the specific limit should be determined by the healthcare provider based on the client's individual needs.

C) This choice is incorrect because while potassium intake may need to be monitored, restricting potassium-rich foods is not a universal instruction for clients with CHF. It depends on the client's overall potassium levels and specific medication regimen.

D) This choice is correct. Following a low-sodium diet is essential for clients with congestive heart failure to reduce fluid retention and manage symptoms of fluid overload.
