Which education about health promotion would the nurse include regarding head and neck cancer?

A. Fatigue: While fatigue can occur in lung cancer patients, it is not the most common symptom. Fatigue is more of a generalized symptom that can be seen in many diseases, not specific to lung cancer.
B. Hoarseness: Hoarseness can be a symptom of lung cancer, particularly if a tumor is affecting the laryngeal nerves. However, it is less common than a persistent cough and is not usually the initial symptom.
C. Anorexia: Anorexia (loss of appetite) can occur in patients with advanced cancer, including lung cancer, but it is not the most common presenting symptom. Weight loss due to anorexia is more common in later stages.
D. Persistent cough: This is the correct answer. A persistent cough is the most common symptom of lung cancer, especially in the early stages. The cough may be dry or productive and is often overlooked or mistaken for a chronic respiratory condition. It is frequently one of the first signs that leads to further investigation and diagnosis.

A. Cerebral edema is the most dangerous complication associated with the administration of hypotonic fluids in patients with diabetic ketoacidosis (DKA). This occurs because hypotonic fluids cause rapid shifts in fluid and electrolytes, which can lead to swelling of the brain, especially in children. The risk is heightened if fluids are replaced too quickly.
B. Polyuria is a common symptom of diabetic ketoacidosis due to high blood glucose levels and osmotic diuresis, but it is not caused by hypotonic fluid administration.
C. Hypokalemia is a potential risk in DKA but typically arises from the shift of potassium from the extracellular to intracellular space during treatment, especially with insulin administration, not from the use of hypotonic fluids.
D. Metabolic acidosis is a hallmark of diabetic ketoacidosis itself and is caused by the accumulation of ketones. It is not caused by hypotonic fluid replacement.
