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

Explanation

A. "The test needs to be repeated following a 12-hour fast."
This statement is not accurate. The hemoglobin A1c test does not require fasting. It reflects the average blood glucose levels over the past two to three months and is not affected by short-term changes in diet or fasting.

B. "It tells us about your sugar control for the last 3 months."
This statement is accurate. The hemoglobin A1c test provides information about the average blood glucose levels over the past two to three months. It's a valuable tool for assessing long-term glycemic control.

C. "It looks like you aren't following the prescribed diabetic diet."
The hemoglobin A1c test reflects overall glycemic control over several months and is not solely influenced by recent dietary habits. While diet plays a role in diabetes management, this statement oversimplifies the interpretation of the A1c result.

D. "Your insulin regimen needs to be altered significantly."
While a high A1c may indicate a need for adjustments in the treatment plan, the decision to alter the insulin regimen should be based on a comprehensive assessment of the patient's overall diabetes management, including lifestyle, diet, and other factors. It may not solely be determined by the A1c result.

A. buffalo hump B. hyponatremia C. decreased glucose level D. weight gain E. Craving for salt

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.
