A patient with chronic kidney disease is at risk for developing which of the following electrolyte imbalances?
Decrease in the concentration of calcium in the glomerulus.
Increase in the concentration of potassium in the blood.
Decrease in the concentration of sodium in the blood.
Increase in the concentration of magnesium in the blood.
The Correct Answer is B
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.

Correct Answer is C
Explanation
Bacteria can perform photosynthesis while archaea cannot. Many types of bacteria can generate oxygen from sunlight through photosynthesis, while archaea cannot perform this process.
Choice A is incorrect because neither bacteria nor archaea have a true nucleus. Both are prokaryotic organisms.
Choice B is incorrect because archaea reproduce by fission, fragmentation, or budding, while bacteria can produce spores and divide sexually or asexually. Choice D is incorrect because archaeal and bacterial flagella are constructed differently.
Correct Answer is A
Explanation
The body regulates blood pH through several mechanisms, including chemical buffers, the respiratory system, and the urinary system.
The respiratory system can adjust blood pH by changing the rate of respiration to remove or retain CO2.
When there is excess acid in the blood, the respiratory rate increases to remove more CO2, which helps to raise blood pH.
Choice B is incorrect because decreasing the respiration rate would retain CO2, which would lower blood pH.
Choice C is incorrect because increased water intake would not directly affect blood pH levels.
Choice D is incorrect because decreased water intake would not directly affect blood pH levels.
