Which physiological effect of immobility can lead to impaired circulation and increased risk of deep vein thrombosis?

A.

Decreased respiratory function

B.

Decreased muscle strength

C.

Decreased cardiac output

D.

Decreased bone density

Answer and Explanation

The Correct Answer is C

Immobility can lead to decreased cardiac output due to reduced activity and muscle contraction. This can result in impaired circulation, increased venous stasis, and an elevated risk of deep vein thrombosis (DVT).

Incorrect choices:

a. Decreased respiratory function is a different effect of immobility and can lead to respiratory complications such as atelectasis or pneumonia. 

b. Decreased muscle strength is another effect of immobility but is not directly associated with an increased risk of deep vein thrombosis. 

d. Decreased bone density is a consequence of immobility, but it is not specifically related to impaired circulation and DVT.

Correct Answer is B

Explanation

Immobility can lead to reduced lung expansion, shallow breathing, and inadequate ventilation, which can result in hypoxia or decreased oxygenation of tissues.

Incorrect choices:

a. Hyperventilation refers to an increased rate or depth of breathing and is not typically associated with immobility.

c. Hypotension refers to low blood pressure and is not directly related to respiratory complications caused by immobility.

d. Hypertension refers to high blood pressure and is not directly associated with respiratory complications caused by immobility.
