A nurse is educating a client who is experiencing sleep disturbances and desires to decrease caffeine intake. Which of the following beverages should the nurse recommend?

A) Flushed skin: Flushed skin is not typically associated with hyponatremia. Instead, hyponatremia may present with symptoms such as pallor or cool, clammy skin due to alterations in perfusion and fluid balance.

B) Fever: Fever is not a common manifestation of hyponatremia. Elevated body temperature is typically associated with conditions such as infection or inflammation rather than electrolyte imbalances like hyponatremia.

C) Nausea and vomiting: Hyponatremia, defined as a serum sodium level below 135 mEq/L, can lead to neurological symptoms, including nausea and vomiting. These symptoms occur due to alterations in osmotic pressure and cellular swelling resulting from the relative excess of water compared to sodium in the extracellular fluid. Other neurological symptoms of hyponatremia can include headache, confusion, lethargy, and seizures.

D) Extreme thirst: Extreme thirst, or polydipsia, is more commonly associated with hypernatremia, which is characterized by a serum sodium level above 145 mEq/L. Hypernatremia results from dehydration or a deficit of body water relative to sodium, leading to increased thirst as the body attempts to restore fluid balance.

A. Localized edema:
Localized edema, especially when accompanied by erythema (redness), warmth, and tenderness, can be indicative of an infection in a client with diabetes mellitus. Infections in diabetic patients, particularly those affecting the feet, can lead to localized inflammation and swelling.

B. An increase in RBCs:
An increase in red blood cells (RBCs), known as erythrocytosis, is not typically associated with an infection. Erythrocytosis may occur in conditions such as polycythemia vera or chronic hypoxemia but is not a typical marker of infection.

C. Bradycardia:
Bradycardia, a heart rate slower than the normal range, is not typically associated with infections. Infections often cause tachycardia (an increased heart rate) as part of the body's systemic inflammatory response.

D. An increase in platelets:
An increase in platelets, known as thrombocytosis, is not typically associated with infections. Thrombocytosis can occur in response to various factors, including inflammation, but it is not a specific marker of infection in diabetic clients with foot pain.

E. An increase in neutrophils:
An increase in neutrophils, known as neutrophilia, is a common response to infection. Neutrophils are a type of white blood cell involved in the body's immune response to bacterial infections. In diabetic clients with foot pain, an elevated neutrophil count may suggest the presence of an infection, as the body mobilizes these cells to combat the invading pathogens.
