Chapter 25, Problem 19TYK
Some diuretics are on a list of substances that the International Olympic Committee has banned for use by athletes. What do diuretics do? Propose an explanation for how diuretic use could be an unfair advantage for a competitor in a sport like wrestling, in which weight classes are part of the competition.

Many caffeinated beverages such as coffee, tea, and cola drinks have diuretic effects on the body. Why do caffeinated beverages increase the volume of urine?
Select one:
a. Caffeine increases ADH, which increases the reabsorption of water in the kidneys.
b. Caffeine inhibits ADH, which reduces the reabsorption of water in the kidneys.
c. Caffeine increases ADH, which reduces the reabsorption of water in the kidneys.
d. Caffeine inhibits ADH, which increases the reabsorption of water in the kidneys.
caffeine is also diuretic, which means it increases the movement of water through the kidneys into the urine. Why would this potentially offset its value to a distance athlete?
Hyperaldosteronism (excessive aldosterone release) can be caused by many disease states including tumours in the adrenal gland.
By now, we should be familiar with how this will affect sodium balance and blood pressure, but how would hyperaldosteronism
affect potassium levels and why? Select one potassium effect (a or b) and one cause (c-f).
a. The patient will become hyperkalemic.
O b. The patient will become hypokalemic.
O c. Aldosterone increases sodium reabsorption in the proximal tubule. Increased sodium reabsorption increases water reabsorption, which then
establishes a concentration gradient to increase potassium reabsorption.
Od. Aldosterone increases sodium reabsorption in the collecting duct. Increased sodium reabsorption increases water reabsorption, which then
establishes a concentration gradient to increase potassium reabsorption.
O e. Aldosterone increases sodium reabsorption in the collecting duct by increasing expression of EnaCs, sodium/potassium exchangers, and…

- Acetazolamide is a diuretic that blocks the activity of the enzyme carbonic anhydrase inside kidney tubule cells. This blockage prevents theformation of carbonic acid from CO2 and water. Normally, carbonicacid dissociates to form H+ and HCO3−, and the H+ is exchanged forNa+ from the urine. Blocking the formation of H+ in the tubule cellsblocks Na+ reabsorption, thus inhibiting water reabsorption andproducing the diuretic effect. With this information in mind, what effectdoes acetazolamide have on blood pH, urine pH, and respiratory rate?arrow_forwardWhich of the following is true regarding aldosterone and ADH? (SELECT ALL THAT APPLY) Aldosterone and ADH are released when a person in overhydrated. Aldosterone and ADH work in the same way but have opposite outcomes. Aldosterone and ADH work in slightly different ways but have the same outcome. Aldosterone and ADH are released when a person in dehydrated.arrow_forwardThe steroid nandrolone, which is found naturally in horses, is administered to racing horses to aid in recovery. Because it is an anabolic steroid, nandrolone levels in excess of normal background levels disqualify a horse from racing. For example, to race in the Kentucky Derby, a gelding (a castrated male horse) may have no more than 1 ng/mL in the urine, whereas an unaltered male horse may have no more than 45 ng/mL of the metabolite estrane-3,17-diol in the urine. Knowing that nandrolone is an anabolic steroid, which hormone would you expect it to closely resemble? (testosterone cortisol O progesterone O epinephrine antidiuretic hormone During metabolism, carbon 3 and carbon 4 of nandrolone are reduced, forming the metabolite estrane-3,17-diol. Modify nandrolone to give estrane-3,17-diol. Select Draw Rings More Erase S с O 0 H ✪ ا قد 2 oarrow_forward
- An athlete tested positive for Methylhexaneamine in urine with a level of 0.90 µg/mL. At her appeal in the Court of Arbitration, she quotes a highly respected scientific publication that states that at levels of 1.0 µg/mL there is no performance enhancement. If the athlete’s levels are indeed below this threshold, the athlete can face a year’s suspension instead of a ban for life. Use the Estimate of Uncertainty to determine if the Athlete should be given a 1 year suspension or banned for life.arrow_forwardSome people advocate drinking one’s own urine, claiming significant health benefits. What problems do you see with this “alternative therapy”? Are there conditions under which this might be advisable?arrow_forwardUse the following information to answer the next question.
