What are the absolute contraindications to arterial blood gas (ABG) sampling?

• Distorted anatomy and obesity

• Vascular disease and obesity

• Local infection and obesity

• Severe coagulopathy and obesity

What is the purpose of arterial blood gas (ABG) sampling?

• Evaluating bone density

• Measuring blood glucose levels

• Assessing liver function

• Monitoring acid-base status

What are some sources of errors in arterial blood gas (ABG) sampling?

• Air bubbles and excessive heparin

• Delay in analyzing the specimen and gas diffusion

• Acid-base balance and air bubbles

• Excessive heparin and gas diffusion

What is the purpose of determining the type of acid-base imbalance in arterial blood gas (ABG) analysis?

• To determine the patient's age

• To assess liver function

• To manage the underlying cause of the imbalance

• To evaluate bone density

What does metabolic acidosis indicate in arterial blood gas (ABG) interpretation?

• Excessive carbon dioxide levels

• High pH and high bicarbonate levels

• Excessive oxygen levels

• Low pH and low bicarbonate levels

What does respiratory alkalosis indicate in arterial blood gas (ABG) interpretation?

• Excessive carbon dioxide levels

• Low pH and low bicarbonate levels

• High pH and high bicarbonate levels

• Excessive oxygen levels

What is the purpose of compensation in arterial blood gas (ABG) analysis?

• To worsen the acid-base imbalance

• To maintain the acid-base imbalance

• To correct the acid-base imbalance

• To prevent the acid-base imbalance

What is a normal blood pH value?

• 7.30-7.40

• 7.34-7.49

• 7.3-7.4

• 7.35-7.45

How can deviations in ABG values affect patient care?

• ABG values have no impact on patient care decisions.
• Deviations in ABG values only affect laboratory results, not patient treatment.
• ABG values are irrelevant in emergency situations.
• Deviations in ABG values can lead to critical adjustments in patient care, including respiratory support and medication changes.

What does a low PaO2 level indicate?

• Hypercapnia

• Hypoxemia

• Metabolic acidosis

• Respiratory alkalosis
