Which statement about inadequate breathing is correct?

A respiratory rate that is either too fast or too slow may be a sign of inadequate breathing. Respiratory distress occurs with many medical and trauma problems and spans the age groups, making choice b inaccurate. An increased work (effort) of breathing frequently accompanies inadequate breathing as the patient attempts to compensate, but it should never be considered a “normal sign” as suggested by choice c. Patients may breathe shallowly or deeply for a number of reasons, only one of which is to compensate for an abnormal rate, making choice d inaccurate.
