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.

Explanation
During the menstrual cycle, the corpus luteum in the ovary produces progesterone to prepare the endometrium for potential implantation.
Choice B is incorrect because fimbriae are finger-like projections at the end of the fallopian tubes that help guide the egg into the tube.
Choice C is incorrect because a follicle is a sac in the ovary that contains an immature egg.
Choice D is incorrect because the ovarian ligament is a fibrous band of tissue that connects the ovary to the uterus.
Correct Answer is C
Explanation
Granzymes are a family of serine proteases that are stored in and secreted from the cytotoxic granules of cytotoxic T lymphocytes (CTL) and natural killer (NK) cells.
They work in synergy with perforin, a pore-forming toxin, to induce apoptosis in target cells.
Perforin is necessary for the delivery of granzyme B to the target cell cytosol where caspase-dependent and -independent pathways to apoptosis are activated.
Perforins (choice A) are pore-forming toxins that work in synergy with granzymes to induce apoptosis in target cells.
Cytokines (choice B) are signaling molecules that regulate immune responses but do not directly induce apoptosis in target cells.
Interferons (choice D) are a type of cytokine that play a role in immune responses but do not directly induce apoptosis in target cells.
