Answer 1

10 C Carbonic anhydrase within the redblood cells quikly converts the carbondioxide into carbonic acid .

11b ventral respiratory group contains the respiratory rythm generator located in the Botzinger complex in the upper part of the VRG ,muscles mostly for expiration.it contains both inspiratory and exhilatory neurons.

12 a When checking breath sounds for acute exacerbration in asthma the sound heard is wheezing.

13 c it is a condition in which the sternum and rib cage grow abnormally and has a caved appearance of the chest.

14 d.This tests are performed to rule out pneumonia or bronchitis.

15 c Mobitz1 is usually due to reversible conduction block at the level of the AV node.Sometimes QRS complex cluster into groups ,separated by short pauses.

16 d

17 d five general approaches are used in the treatment of ACT are CPT,coughing and related expulsion techniques,PAP ie positive airway pressure with PEP positive expiratory pressure,oscillation methods,mobilization and physical actiity.

18 d Minute volume=Tidal volume*Respiratory rate

12*600=7200

20 a When the ventricles contract ,ventricular pressure increases ,closing the atrio ventricular valves leaflets.Two additional structures ,the pappilary muscles and the chordae tendinae ,maintain valve closure .So chordae tendinae corresponds to ventricular surface.
