Anesthesia NAVLE

Question 1

What is the normal pH range for blood?

Answer 1

7.35-7.45

This range is critical for maintaining proper physiological functions.

Question 2

What is the normal range for PaCO2 in mmHg?

Answer 2

35-45 mmHg

This value is important for assessing respiratory function.

Question 3

What is the significance of PaO2 in relation to FiO2?

Answer 3

PaO2:FiO2 > 500

This ratio is used to assess the severity of hypoxemia.

Question 4

What is the lactate level considered normal?

Answer 4

< 2 mmol/L

Elevated lactate levels can indicate tissue hypoxia.

Question 5

What indicates hypoxemia?

Answer 5

PaO2 < 60 mmHg or SpO2 < 90%

Hypoxemia can lead to serious complications if not addressed.

Question 6

What does a yellow flag indicate in beach safety?

Answer 6

Caution, limited swimming

Beach flags communicate water safety conditions.

Question 7

What is the Central Venous Pressure (CVP) a measure of?

Answer 7

Direct measure of BP in the Cr. Vena Cava

CVP provides insight into venous blood volume and cardiac output.

Question 8

What is the MAC of Halothane in dogs?

Answer 8

0.87 (K9)

MAC (Minimum Alveolar Concentration) indicates the potency of the anesthetic.

Question 9

What is a potential complication of Sevoflurane?

Answer 9

Renal Necrosis from Compound A

This degradation product can be harmful in certain conditions.

Question 10

What is the MAC of Methoxyflurane in dogs?

Answer 10

0.29 (K9 - Most potent)

This indicates that Methoxyflurane is the most potent inhalant anesthetic.

Question 11

What is the purpose of a Bain Circuit?

Answer 11

Prevent re-breathing by maintaining high flow rate of O2

It is a type of non-rebreathing circuit used in anesthesia.

Question 12

What is the recommended action regarding food withholding before anesthesia?

Answer 12

Withhold the food

This is important to reduce the risk of aspiration during anesthesia.

Question 13

What is the effect of hypoventilation on CO2 levels?

Answer 13

CO2 buildup > Acidotic state (low pH)

This condition necessitates an increase in the rate of mechanical ventilation.

Question 14

What is the effect of hyperventilation on arterial PCO2?

Answer 14

Decrease in arterial PCO2 > Alkalotic state

This condition may require a decrease in ventilation.

Question 15

What is the O2 saturation when arterial O2 pressure is 60 mmHg?

Answer 15

90%

This relationship is critical for understanding oxygen delivery.

Question 16

What does peripheral vasoconstriction indicate?

Answer 16

Absence of wave with 100% O2 saturation

This can be a sign of hypertension.
