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)

Answer and Explanation

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 B

Explanation

A. Increase the intake of vitamin E to enhance absorption:
While vitamin C can enhance iron absorption, vitamin E does not play a significant role in iron absorption. Vitamin C-rich foods can be advised to enhance iron absorption.

B. Iron will cause the stools to darken in color:
This statement is accurate. Iron supplements can cause stools to appear darker in color, often black or greenish-black. This change in stool color is normal and expected when taking iron supplements.

C. Take the iron with dairy products to enhance absorption:
Dairy products can inhibit iron absorption. It's better to take iron supplements with vitamin C-rich foods or orange juice to enhance absorption.

D. Limit foods high in fiber due to the risk for diarrhea:
Fiber-rich foods do not necessarily need to be limited when taking iron supplements. However, some individuals may experience constipation when taking iron supplements, in which case increasing fluid intake and dietary fiber can help alleviate constipation.

A. 1645 B. 1615 C. 1545 D. 1600

Correct Answer is B

Explanation

A.Regular insulin typically begins to take effect 30 minutes after administration. Administering insulin at the time of the meal (1645) would not allow enough time for the insulin to reach its onset of action, potentially resulting in the blood glucose level being high during the meal.

B.Regular insulin has an onset of action of 30 minutes. By administering the insulin at 1615, it will start to take effect by 1645, when the meal arrives, and help ensure the insulin action aligns with the meal, preventing postprandial hyperglycemia.

C.Administering insulin at 1545 would be too early and could lead to the insulin peaking before the meal, which could result in hypoglycemia if the insulin peak occurs before the patient has food to absorb the glucose.

D.Administering insulin at 1600 would result in the insulin starting to work too soon, with the onset happening before the meal and possibly leading to hypoglycemia if the insulin peaks before the meal is consumed.
