Shelly has not been feeling well lately. After her blood work comes back, her doctor says that she has _______. The blood work showed that her arterial blood pH was 7.3, her PCO2 was 60 mm Hg and her bicarbonate level was 32 mEq/L. (A) chronic respiratory acidosis (B) metabolic acidosis (C) chronic respiratory alkalosis (D) none of these is correct

80. Of the following, the most likely cause for her condition is that Shelly ____. (A) is a three pack-a-day smoker (B) takes a lot of Tums® antacids (C) is a diabetic (D) vomits a lot from her motion sickness

Explanation / Answer

56. True, diarrhoea can contribute to metabolic alkalosis, because of loss of sodium,chloride and hydrogen ions

57. True average ph of urine is above 6.because during daily normal metabolism,acids are produced continuously.therefore,unless acids are excreted,they accumulate in the body and produce acidosis. inorder to prevent acidosis,body excretes excess acids through kidney into urine,the process that leads to acidification of urine,which is a normal physiological phenomenon.

58. False .the chemical reactions occuring in the body are in equillibria.Specific organs has its own equillibria like blood is slightly basic..ph of stomach is slightly acidic in nature.So we have different ph in our body system. But most of the people tend to be alkaline. 60 to 70% of peoples are suffering from alkalosis symptoms and parasympathetic imbalance or a slow oxidative imbalance.This tends to push their body ph to a higher level.

59. True..The normal ph f blood is between 7.35 and 7.45

60.True..Normal ph of plasma is maintained within 7.35 to 7.45...To maintain the slender plasma ph range of the blood buffer system should work continously and effectively.....The albumin component of plasma protein acts as a buffer.The histidine residue of albumin is responsible for its buffering action

61. True..to maintain the ph level

62..True,hunger receptors are located in hypothalamus

80. chronic respiratory acidosis

        because (A) three pack a day smoker
