Question

Hyperventilation could be associated with all of the following, EXCEPT: Select one: a. an overdose of aspirin. b. a narcotic overdose. c. a respiratory infection. d. high blood glucose levels.

Answer 1

Answer:

C. Narcotic overdose

Explanation:

The narcotics cause respiratory depression as they decrease the response to the increased partial pressure of carbondioxide pCO2 , thus resulting in depression of the respiratory centre in brain and no hyperventilation occurs  Hence option B is the right answer.

Hyperventilation is occurring in option  A because aspirin overdose cause direct respiratory center stimulation resulting in respiratory alkalosis causing hyperventilation.

Hyperventilation is occuring in option C  as most of the respiratory infections e.g pneumonia is associated with hyperventilation due to swelling and accumuation of fluid in lungs causing fast breath.

Hyperventilation also occurs in high blood glucose levels hence option D is also excluded.
