A patient with a history of heart failure is prescribed a medication that increases urine output to reduce fluid buildup.
Which of the following statements best describes the mechanism of action of the prescribed medication?

A catalyst provides a new reaction pathway in which a lower activation energy is offered.

This allows more reactant molecules to collide with enough energy to surmount the smaller energy barrier, increasing the rate of reaction 2.

Choice A, It increases the activation energy required for the reaction, is not the correct answer because it describes the opposite effect of a catalyst.

Choice C, It has no effect on the activation energy required for the reaction, is not the correct answer because a catalyst does have an effect on activation energy.

Choice D, It increases the rate of reaction but has no effect on the activation energy, is not the correct answer because a catalyst increases the rate of reaction by decreasing the activation energy.

A patient with chronic kidney disease is at risk for developing an increase in the concentration of potassium in the blood.

The kidneys play a pivotal role in the regulation of electrolyte balance.

With the progressive loss of kidney function, derangements in electrolytes inevitably occur and contribute to poor patient outcomes123.

Choice A is incorrect because calcium concentration is not regulated in the glomerulus.

Choice C is incorrect because chronic kidney disease can result in either an increase or decrease in sodium concentration in the blood.

Choice D is incorrect because chronic kidney disease does not necessarily result in an increase in magnesium concentration in the blood.
