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","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.

A. The need to match the daily steroid dose to immediate symptoms B. The importance of monitoring liver function C. The need for life-long steroid replacement D. The possibility of extreme weight loss from use of corticosteroids

Correct Answer is C

Explanation

A. The need to match the daily steroid dose to immediate symptoms:
Explanation: Adjusting the steroid dose based on immediate symptoms is not a recommended approach. Patients should follow the prescribed regimen provided by their healthcare provider.

B. The importance of monitoring liver function:
Explanation: While monitoring liver function is important for some medications, it is not the primary focus when teaching about hormone replacement therapy in Addison's disease. The emphasis is on the need for life-long steroid replacement.

C. The need for life-long steroid replacement:
Explanation: Patients with Addison's disease require life-long steroid replacement therapy to compensate for the deficiency in adrenal hormones. It's important for the patient to understand that adherence to the prescribed steroid regimen is essential for maintaining health and preventing adrenal crisis.

D. The possibility extreme weight loss from the use of corticosteroids:
Explanation: While corticosteroids can have various side effects, extreme weight loss is not a typical or desired outcome of steroid therapy for Addison's disease. Weight changes and potential side effects should be discussed, but the emphasis should be on the importance of long-term steroid replacement.
