Resp Acidosis And Alkalosis

Question 1

What is a common cause of respiratory acidosis?

Answer 1

COPD

COPD stands for Chronic Obstructive Pulmonary Disease.

Question 2

List two conditions that can lead to respiratory acidosis.

Answer 2

• Decompensation in other respiratory conditions
• Neuromuscular disease

Question 3

What syndrome is associated with respiratory acidosis?

Answer 3

Obesity hypoventilation syndrome

This syndrome occurs when obesity leads to hypoventilation, causing increased carbon dioxide levels.

Question 4

Name a class of drugs that can cause respiratory acidosis.

Answer 4

Sedative drugs: benzodiazepines, opiate overdose

Question 5

What is a common cause of respiratory alkalosis?

Answer 5

Anxiety leading to hyperventilation

Hyperventilation causes excessive breathing, reducing carbon dioxide levels.

Question 6

List three causes of respiratory alkalosis.

Answer 6

• Pulmonary embolism
• Salicylate poisoning
• CNS disorders (stroke, subarachnoid haemorrhage, encephalitis)

Question 7

At high altitudes, what acid-base disturbance may occur?

Answer 7

Respiratory alkalosis

Question 8

How does pregnancy affect respiratory function?

Answer 8

It can lead to respiratory alkalosis.

Question 9

Fill in the blank: Salicylate overdose leads to a mixed respiratory alkalosis and _______.

Answer 9

metabolic acidosis

Question 10

What happens to the respiratory center during salicylate overdose?

Answer 10

Early stimulation leads to respiratory alkalosis

This occurs before the direct acid effects of salicylates take effect.

Question 11

What can combined with acute renal failure lead to acidosis during salicylate overdose?

Answer 11

Direct acid effects of salicylates
