The nurse is caring for a client with a nasogastric tube that is attached to low suction. The nurse monitors the client for manifestations of which disorder that the client is at risk for?
Respiratory acidosis
Metabolic acidosis
Respiratory alkalosis
Metabolic alkalosis
The Correct Answer is D
A. Respiratory acidosis:
This occurs when there is inadequate ventilation, leading to an accumulation of carbon dioxide (CO2) in the blood. In the context of a nasogastric tube attached to low suction, respiratory acidosis is not the primary concern. It is more associated with conditions like respiratory depression or lung diseases.
B. Metabolic acidosis:
Metabolic acidosis results from an excess of acid or a loss of bicarbonate. It is not the typical outcome of a nasogastric tube attached to low suction. Conditions like diarrhea or renal failure are more commonly associated with metabolic acidosis.
C. Respiratory alkalosis:
Respiratory alkalosis occurs when there is excessive loss of carbon dioxide from the body, often due to hyperventilation. This is not a typical consequence of a nasogastric tube attached to low suction.
D. Metabolic alkalosis:
Metabolic alkalosis is characterized by an excess of bicarbonate or a loss of acid. In the given context, with the nasogastric tube attached to low suction, there is a potential loss of gastric acid, contributing to metabolic alkalosis.

Correct Answer is D
Explanation
A. Respiratory Acidosis:
Explanation: Respiratory acidosis occurs when there is inadequate elimination of carbon dioxide, leading to an increase in PaCO2 and a decrease in blood pH. This is typically associated with conditions that impair ventilation.
B. Metabolic Alkalosis:
Explanation: Metabolic alkalosis is characterized by an elevated blood pH and bicarbonate (HCO3-) concentration. It is not directly caused by hyperventilation but is often associated with conditions such as excessive vomiting or excessive bicarbonate intake.
C. Metabolic Acidosis:
Explanation: Metabolic acidosis is characterized by a decrease in blood pH and bicarbonate concentration. It is not directly caused by hyperventilation but may result from conditions such as diabetic ketoacidosis or lactic acidosis.
D. Respiratory Alkalosis:
Explanation: Hyperventilation is the most common cause of respiratory alkalosis. During hyperventilation, there is an excessive loss of carbon dioxide (CO2) through rapid breathing, leading to a decrease in the partial pressure of carbon dioxide (PaCO2) in the blood. This results in an increase in blood pH, causing an alkalotic state.
Correct Answer is D
Explanation
A. Flushed skin: Flushed or warm skin is more characteristic of hyperthyroidism, where there is an excess of thyroid hormones.
B. Palpitations: Palpitations or a rapid heartbeat are more characteristic of hyperthyroidism, where there is an excess of thyroid hormones.
C. Bulging eyes: Bulging or protruding eyes, known as exophthalmos, is a characteristic sign of Graves' disease, which is a specific type of hyperthyroidism.
D. Fatigue: This is correct. Fatigue is a common symptom of hypothyroidism, reflecting the overall slowing down of the body's processes.
