A patient has the following blood gases: PaCO2 33, pH 7.50, HCO3 23. Which of the following could NOT be the cause of this condition?
Aspirin toxicity
Fever
Anxiety attack
Chronic obstructive pulmonary disease (COPD)
The Correct Answer is D
A. Aspirin Toxicity:
Effect on Blood Gases: Aspirin toxicity can cause respiratory alkalosis due to increased respiratory rate (hyperventilation), leading to a decreased PaCO2 and increased pH.
Relation to Given Blood Gases: It could potentially cause the observed blood gas values (low PaCO2 and high pH), making it a possible cause.
B. Fever:
Effect on Blood Gases: Fever might cause hyperventilation, resulting in respiratory alkalosis with decreased PaCO2 and increased pH.
Relation to Given Blood Gases: It could potentially cause the observed blood gas values.
C. Anxiety Attack:
Effect on Blood Gases: Anxiety attacks can lead to hyperventilation and subsequent respiratory alkalosis with low PaCO2 and high pH.
Relation to Given Blood Gases: It could potentially cause the observed blood gas values.
D. Chronic Obstructive Pulmonary Disease (COPD):
Effect on Blood Gases: COPD typically causes respiratory acidosis due to impaired gas exchange, resulting in elevated PaCO2 and decreased pH.
Relation to Given Blood Gases: COPD wouldn't typically cause the observed blood gas values of low PaCO2 and high pH.

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.
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.
