, Polyuria and hyperventilation

Explanation: Marked water deficit is manifested by symptoms of dehydration: headache,

thirst, dry skin and mucous membranes, elevated temperature, weight loss,

and decreased or concentrated urine (with the exception of diabetes

insipidus). Skin turgor may be normal or decreased. Symptoms of

hypovolemia, including tachycardia, weak pulses, and postural

hypotension, may be present.




Question 3. Question : How does the loss of chloride during vomiting cause metabolic

alkalosis?


Loss of chloride stimulates the release of aldosterone, which

causes the retained sodium to bind with the chloride.


Loss of chloride causes hydrogen to move into the cell and

exchange with potassium to maintain cation balance.


Loss of chloride causes retention of bicarbonate to maintain

the anion balance.


Loss of chloride causes hypoventilation to compensate for the

metabolic alkalosis.

Explanation: When acid loss is caused by vomiting with depletion of ECF and

, chloride (hypochloremic metabolic alkalosis), renal compensation is not

very effective because the volume depletion and loss of electrolytes

(Na+, K+, H+, Cl-) stimulate a paradoxical response by the kidneys. The

kidneys increase sodium and bicarbonate reabsorption with excretion of

hydrogen. Bicarbonate is reabsorbed to maintain an anionic balance

because the ECF chloride concentration is decreased.




Question 4. Question : When thirst is experienced, how are osmoreceptors activated?


By an increase in the antidiuretic hormone secreted into the

plasma


By an increase in aldosterone secreted into the plasma


By an increase in the hydrostatic pressure of the plasma


By an increase in the osmotic pressure of the plasma

Explanation: Thirst is experienced when water loss equals 2% of an individual’s body

weight or when there is an increase in osmolality. Dry mouth,

hyperosmolality, and plasma volume depletion activate osmoreceptors

(neurons located in the hypothalamus that are stimulated by increased

osmolality).
