A nurse is caring for a client who had radiation therapy and is experiencing painful dermatitis. The nurse should identify the client is experiencing which of the following types of pain?

A) Administer and teach about medications to suppress stage III sleep:
Suppressing stage III sleep is not a primary intervention for sleepwalking and could potentially disrupt the client’s overall sleep quality.

B) Encourage the child to verbalize feelings regarding sleep pattern:
While understanding feelings about sleep patterns may be helpful, it is not the immediate priority in managing sleepwalking.

C) Provide a quiet environment for nighttime sleep:
A quiet environment is generally beneficial for good sleep hygiene but does not directly address the safety concerns associated with sleepwalking.

D) Maintain patient safety during episodes of somnambulism:
Ensuring the client’s safety is the primary focus. Sleepwalking can lead to accidents or injuries; therefore, implementing safety measures to prevent harm during episodes of somnambulism is crucial. This may include securing the environment, using safety gates, and ensuring the client’s immediate surroundings are safe.

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.
