Arterial Blood Gases Quiz

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

• Severe coagulopathy and obesity

• Local infection and distorted anatomy

• Currently taking blood thinners and vascular disease

• Severe peripheral vascular disease and arteriovenous fistulas

What are some factors that make arterial blood gas (ABG) sampling difficult?

• Difficulty in positioning the patient and obesity

• Pulses that cannot be identified easily and obesity

• Vascular disease and poor distal perfusion

• Uncooperative patient and obesity

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

How can healthcare providers interpret arterial blood gases (ABGs) given a clinical scenario?

• By guessing randomly

• By avoiding the clinical scenario

• By comparing and contrasting metabolic and respiratory imbalances

• By ignoring the clinical scenario
