The nurse has an older client. The nurse notices that the client has kyphosis. Which of the following concerns may the nurse have about this client?
Decrease oxygenation due to decrease in muscle function
Decrease oxygenation due to inability to change thoracic pressure adequately
Decrease oxygenation due to loss of elasticity of lung tissue
Decrease in oxygenation due to decrease nervous system response
The Correct Answer is B
A. Decrease oxygenation due to decrease in muscle function- kyphosis primarily affects skeletal structure, not muscles.
B. Decrease oxygenation due to inability to change thoracic pressure adequately- kyphosis alters thoracic cage shape, restricting expansion and limiting pressure changes required for ventilation.
C. Decrease oxygenation due to loss of elasticity of lung tissue- this relates more to normal aging or emphysema, not kyphosis.
D. Decrease in oxygenation due to decrease nervous system response- kyphosis doesn’t affect the nervous system directly.

Correct Answer is A
Explanation
A. CO₂: High CO₂ (hypercapnia) stimulates the respiratory center to increase breathing.
B. Volume: Blood volume doesn't directly affect respiratory rate.
C. Bilirubin: This is associated with liver function and jaundice, not respiration.
D. Calcium: Calcium levels affect muscle function, not the breathing rate directly.
Correct Answer is B
Explanation
A. Cerebellum: The cerebellum coordinates movement and balance, not respiration.
B. Medulla oblongata: The medulla controls the rate and depth of breathing by monitoring CO₂ and pH levels.
C. Hypothalamus: The hypothalamus regulates homeostasis and emotions, not directly breathing.
D. Cerebrum: The cerebrum controls voluntary actions and higher-level thinking, not automatic respiration.
