11. TRUE or FALSE Alkalosis refers to a state of lower than normal pH in the ECF
- ATrue
- BFalse
2TRUE or FALSE Alkalosis makes neurons more excitable and acidosis makes neurons less excitable
- ATrue
- BFalse
3TRUE or FALSE The majority of food we eat creates acid in the body and most metabolic processes create alkalinity
- ATrue
- BFalse
4Increased carbon dioxide in the ECF will
- AResult in decreased pH
- BResult in increased pH
- CHave no effect on pH
- DCombine with carbonic acid to create bicarbonate ions
5The first line of defence that is used to maintain homeostatic pH levels is
- ABuffers
- BVentilation responses
- CRenal controls
- DDietary controls
6TRUE or FALSE A buffer is a molecule that can combine with a relatively large amount of an acid or base without a resulting large change in pH. Buffer molecules are only found in the ECF, they are not located within cells.
- ATrue
- BFalse
7When acid from metabolic sources combines with bicarbonate ion in the ecf
- AWater and Carbon dioxide are produced
- BIncreased ventilation results from increased plasma carbon dioxide
- CWater and carbon dioxide produced are excreted from the kidneys
- DBoth a and b are correct
88. Holding your breath can result in
- AIncreased pH
- BDecreased pH
- CIncreased bicarbonate ions in ecf
- DDecreased hydrogen ion excretion at the kidneys
9TRUE or FALSE Hyperventilation results in the ecf becoming more acidic
- ATrue
- BFalse
10 Increased hydrogen ion concentration in the ecf
- AIs detected by peripheral chemoreceptors in the aorta and carotid arteries
- BCan trigger hypoventilation
- CWill diminish oxygen levels in plasma
- DBoth a and b are correct
11In metabolic acidosis
- AThe kidneys will secrete increased hydrogen ions
- BThe kidneys will reabsorb increased bicarbonate ions
- CThe ventilation response will increase rate and depth of breathing
- DAll of the above are correct
12TRUE or FALSE In response to alkalosis the kidney will excrete hydrogen ions and reabsorb bicarbonate ions
- ATrue
- BFalse
13The slowest compensation mechanism for acid-base imbalance in the body is
- ABuffers inside cells
- BBuffers in ECF
- CVentilation responses
- DKidney responses
14TRUE or FALSE In order to maintain pH within homeostatic range in the ECF, fine tuning of ECF [H+] occurs in the proximal tubule of the kidney
- ATrue
- BFalse
15Respiratory acidosis results from
- Aingestion of an acid forming meal
- BAnaerobic exercise resulting in excess lactic acid production
- CHyperventilation
- DHypoventilation
16Metabolic alkalosis can be corrected by
- AHyperventilation
- BHypoventilation
- CRenal excretion of H+
- DIngestion of bicarbonate ions
