A nurse is preparing to initiate a continuous enteral feeding through an open system to a client. Which of the following actions should the nurse take?

A. Hyponatremia: Hyponatremia is characterized by low sodium levels in the blood and can lead to symptoms such as weakness, confusion, and seizures. While hyponatremia can contribute to fluid imbalance, the client's presentation with shortness of breath, lower extremity swelling, crackles in the lungs, and elevated blood pressure is more indicative of fluid volume excess rather than hyponatremia.

B. Hypervolemia: Hypervolemia, or fluid volume excess, occurs when there is an abnormal increase in the extracellular fluid volume. This can lead to symptoms such as shortness of breath, crackles in the lungs (indicative of pulmonary edema), peripheral edema, and elevated blood pressure. Given the client's reported symptoms and assessment findings, hypervolemia is the most likely diagnosis.

C. Hypovolemia: Hypovolemia, or fluid volume deficit, occurs when there is a decrease in the extracellular fluid volume. This condition is characterized by symptoms such as thirst, dry mucous membranes, decreased urine output, and hypotension. The client in this scenario presents with signs and symptoms consistent with fluid volume excess rather than hypovolemia.

D. Hyperkalemia: Hyperkalemia is characterized by elevated potassium levels in the blood and can lead to symptoms such as muscle weakness, cardiac dysrhythmias, and nausea. While hyperkalemia can occur in clients with end-stage kidney disease, the client's reported symptoms and assessment findings are more suggestive of fluid volume excess rather than hyperkalemia.

A) Viral infection:
Chronic stress can suppress the immune system, making individuals more susceptible to infections, including viral infections. Prolonged stress can dysregulate the immune response, leading to increased vulnerability to various illnesses.

B) Increased cognitive awareness:
Chronic stress often impairs cognitive function rather than enhancing it. It can lead to difficulties with concentration, memory problems, and cognitive fatigue due to the continuous activation of the body's stress response system.

C) Hypotension:
Chronic stress typically leads to increased blood pressure rather than hypotension. Stress activates the sympathetic nervous system, resulting in the release of stress hormones like cortisol and adrenaline, which can elevate blood pressure over time.

D) Increased energy:
While acute stress can trigger a temporary surge in energy due to the release of stress hormones, chronic stress often leads to fatigue and exhaustion. Prolonged activation of the stress response system can deplete energy reserves and disrupt sleep patterns, resulting in feelings of fatigue and lethargy.
