A patient with a longstanding diagnosis of generalized anxiety disorder presents to the emergency room. The triage nurse notes upon an assessment that the patient is hyperventilating. The triage nurse is aware that hyperventilation is the MOST common cause of which acid-base imbalance?

Respiratory Acidosis

Metabolic Alkalosis

Metabolic Acidosis

Respiratory Alkalosis

Answer and Explanation

The Correct Answer is D

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 ["B","C","E"]

Explanation

A. Buffalo hump:
Explanation: A buffalo hump is associated with excess cortisol, which is not a typical manifestation of Addison's disease. Instead, patients with Addison's disease may experience weight loss and muscle wasting.

B. Hyponatremia:
Explanation: Correct. Hyponatremia (low sodium levels) can occur in Addison's disease due to the loss of aldosterone, which plays a role in sodium and water balance.

C. Decreased glucose level:
Explanation: Correct. Addison's disease can lead to hypoglycemia (low blood glucose levels) because cortisol, which is important for maintaining blood glucose, is deficient.

D. Weight gain:
Explanation: Weight gain is not a typical manifestation of Addison's disease. Instead, weight loss and muscle wasting may occur.

E. Craving for salt:
Explanation: Correct. Addison's disease can lead to salt craving, as aldosterone deficiency results in increased sodium loss and potassium retention.

A. "Diet, exercise and oral medications can be effective. I will ask the physician to prescribe Metformin" B. "Your body does not produce insulin, and the only treatment is injected insulin" C. "Glucophage can help your body better utilize the insulin secreted by the pancreas" D. "Initially, you will need injections, but after your body adjusts to the insulin, you can switch to Metformin"

Correct Answer is B

Explanation

A. "Diet, exercise, and oral medications can be effective. I will ask the physician to prescribe Metformin":
Explanation: This statement is not accurate for type 1 diabetes. Type 1 diabetes results from the inability of the pancreas to produce insulin, so oral medications like Metformin, which work to increase insulin sensitivity or reduce glucose production in the liver, are not effective. Insulin replacement is the mainstay of treatment for type 1 diabetes.

B. "Your body does not produce insulin, and the only treatment is injected insulin":
Explanation: This is the correct statement. In type 1 diabetes, the pancreas does not produce insulin or produces very little, and insulin cannot be taken orally because it would be broken down in the digestive system. Therefore, injections are the primary and necessary mode of insulin delivery.

C. "Glucophage can help your body better utilize the insulin secreted by the pancreas":
Explanation: This statement is more applicable to type 2 diabetes, where the pancreas may still produce insulin, but the body's cells are resistant to its effects. In type 1 diabetes, the issue is a lack of insulin production, so medications to improve insulin utilization are not relevant.

D. "Initially, you will need injections, but after your body adjusts to the insulin, you can switch to Metformin":
Explanation: This is not accurate for type 1 diabetes. The need for insulin in type 1 diabetes is not something the body adjusts to over time. Insulin is a lifelong requirement for individuals with type 1 diabetes, and it cannot be replaced by oral medications like Metformin.
