Question

Which of the following statements about body water pools is FALSE? a. Water moves from areas of low osmolarity to high osmolarity. b. The water pools of the body are all interconnected. c. If the osmolarity of one pool changes, it affects the osmolarity of all pools. d. The water content of the body increases with age. e There is more water in the intracellular fluid than in the extracellular fluid. Which of the following increases Na^+ reabsorption in the kidney tubule? a. ADH b. Renin c. ANF d. Insulin e. Calcitriol Why would an increase in plasma Na^+ eventually result in an increase in arterial blood pressure? a. The increase in Na^+ would result in an increase in plasma osmolarity, leading to an increase in blood volume. b. The increase in Na^+ would result in an decrease in plasma osmolarity, leading to an increase in blood volume. c. An increase in Na^+ would increase the osmolarity of the cerebrospinal fluid, thereby increasing water loss through the kidneys. d. An increase in Na^+ would decrease the osmolarity of the cerebrospinal fluid, thereby increasing water loss through the kidneys. e. An increase in Na^+ would increase the osmolarity of plasma, thereby increasing water loss through the through the kidneys. During respiratory acidosis, which of the following would provide the best benefit to a patient? a. Increased alveolar ventilation b. Addition of acid to the blood c. Decreased alveolar respiration d. Waiting for the kidney to secrete large amounts of H^+ e. Addition of whole blood. The renal tubule secretes up to 100 mEq H^+ per day. Why doesn't the pH of urine decline to less than 4.0? a. The kidney accelerates fluid loss to compensate. b. The urine is full of buffers. c. The urine complexes H^+ to albumin secreted in the urine. d. Because the lungs increase ventilation when urine pH approaches 4.0. e. This is a trick question, urine pH can decline to as low as 2.0. Which of the following would likely cause metabolic acidosis? a. Production of lactic acid after exercise b. Diabetes c. Kidney damage d. All of the above e. None of the above Alteration of which of the fluid pools is the most important for the homeostatic regulation of body water? a. Cerebrospinal fluid b. Aqueous humors of the eye c. Plasma d. Interstitial fluid e. Intracellular fluid

Explanation / Answer

Among the following statements the statement saying that the the body water content increases with age because with ageing the risk of dehydration increases. ADH (Anti diuretic hormone) secreted by the posterior pituitary increases the reabsorption on sodium ions aling with water in the distal renal tubules. Well if there is an increase in the plasma sodium ions then osmolarity of plasma will increase and it will cause increase in blood pressure because of the renin-angiotensin mechanism. Respiratory acidosis is caused by an increase in the pCO2 concentration and decreased ventilation and can be controlled by increasing the alveolar ventilation. Well the 6. metabolic acidosis is generally caused by the increased lactic acid production after excercise, diabetes and kidney damage. The kidney increases the fluid loss to compensate the decrease in the pH of urine despite of the secretion of 100 mEq H ions by the renal tubules. 7.The alteration the the plasma volume is very impressed in the homeostatic regulation of body water because the osmoreceptors are activated by the changes in blood volume.
