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
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 A
Explanation
A. With the meal:
Insulin Lispro is a rapid-acting insulin that is designed to be taken just before or with meals.
It helps control the rise in blood sugar that occurs after eating.
B. Post-prandial:
"Post-prandial" refers to after a meal. Insulin Lispro is usually administered before or with a meal to cover the increase in blood glucose that happens after eating.
C. Pre-prandial:
"Pre-prandial" refers to before a meal. This is accurate for Insulin Lispro, as it is given shortly before or with meals.
D. AC/HS:
"AC" stands for "ante cibum," which means before meals, and "HS" stands for "hora somni," which means at bedtime. This terminology is more commonly associated with the timing of oral medications rather than insulin.
