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.

Explanation
A. Vitamin A Deficiency:
Symptoms: Enlarged tongue and smooth, beefy red appearance.
Relevance: Vitamin A deficiency is not typically associated with an enlarged tongue. It is more commonly linked to night blindness and skin issues.
B. Folic Acid Deficiency:
Symptoms: Enlarged tongue and smooth, beefy red appearance.
Relevance: Folic acid deficiency can lead to megaloblastic anemia and glossitis (inflammation of the tongue), which may present as an enlarged, smooth, and red tongue.
C. Vitamin B12 Deficiency:
Symptoms: Enlarged tongue and smooth, beefy red appearance.
Relevance: Vitamin B12 deficiency can cause pernicious anemia and glossitis, resulting in an enlarged, smooth, and red tongue.
D. Vitamin C Deficiency:
Symptoms: Not typically associated with an enlarged tongue.
Relevance: Vitamin C deficiency is more commonly associated with symptoms like scurvy, which includes bleeding gums, joint pain, and skin issues, but not specifically an enlarged tongue.
Correct Answer is A
Explanation
A. Erythropoietin (Epogen):
Explanation: Erythropoietin is a hormone that stimulates the production of red blood cells. In chronic kidney disease, especially when associated with anemia, the production of erythropoietin by the kidneys may be reduced. Erythropoietin (Epogen) is commonly used to stimulate the production of red blood cells and manage anemia in patients with chronic kidney disease.
B. Eltrombopag (Promacta):
Explanation: Eltrombopag is a medication used to stimulate the production of platelets and is primarily indicated for conditions associated with thrombocytopenia (low platelet count). It is not used to treat anemia associated with chronic kidney disease.
C. GM-CSF (Leukine):
Explanation: Granulocyte-macrophage colony-stimulating factor (GM-CSF or Leukine) is a medication that stimulates the production of white blood cells and is used in certain conditions to address decreased white blood cell counts. It is not typically used for managing anemia.
D. Thrombopoietin (TPO):
Explanation: Thrombopoietin is a hormone that stimulates the production of platelets. Medications that mimic the action of thrombopoietin, such as romiplostim and eltrombopag, are used to treat thrombocytopenia. Thrombopoietin is not used for the treatment of anemia.
