Appropriate therapy for prerenal kidney injury includes:
Protein restriction.
Potassium supplementation.
Fluid administration to increase cardiac output.
Fluid restriction.
The Correct Answer is C
Choice A reason: Protein restriction is not a primary treatment for prerenal kidney injury. While managing protein intake can be important in chronic kidney disease to reduce the workload on the kidneys, it is not directly relevant to the acute management of prerenal kidney injury, which primarily involves restoring adequate blood flow to the kidneys.
Choice B reason: Potassium supplementation is not typically necessary for prerenal kidney injury. In fact, in many cases of kidney injury, there is a risk of hyperkalemia (elevated potassium levels) due to reduced kidney function. Therefore, potassium levels need to be monitored, but supplementation is not a standard treatment.
Choice C reason: Fluid administration to increase cardiac output is the appropriate therapy for prerenal kidney injury. Prerenal kidney injury is caused by reduced blood flow to the kidneys, often due to factors like hypovolemia (low blood volume) or heart failure. Administering fluids helps to restore adequate blood flow and perfusion to the kidneys, which can improve kidney function and resolve the prerenal injury.
Choice D reason: Fluid restriction is not appropriate for prerenal kidney injury, which is characterized by reduced blood flow to the kidneys. In cases where hypovolemia or low cardiac output is the cause, restricting fluids would worsen the condition. Instead, increasing fluid intake helps to restore adequate perfusion to the kidneys.

Correct Answer is B
Explanation
Choice A reason: Amphotericin B is typically administered intravenously because it is poorly absorbed from the gastrointestinal tract and thus not suitable for oral administration. It is used to treat severe systemic fungal infections and is known for its potential nephrotoxicity and other adverse effects.
Choice B reason: Azoles, such as fluconazole and itraconazole, generally have lower toxicity compared to amphotericin B. They are often used as first-line treatments for many fungal infections due to their safer side effect profile. Azoles work by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, and are available in both oral and intravenous formulations, making them more versatile in their use.
Choice C reason: While amphotericin B does have some drug interactions, it is not typically known for significantly increasing the levels of many other drugs. Instead, the primary concern with amphotericin B is its potential for nephrotoxicity and other direct adverse effects on the patient.
Choice D reason: Both amphotericin B and azoles are considered broad-spectrum antifungal agents. Amphotericin B is effective against a wide range of fungi, including many that are resistant to other antifungal agents. Azoles are also broad-spectrum and are used to treat a variety of fungal infections, but they generally have a better safety profile than amphotericin B.
Correct Answer is B
Explanation
Choice A reason: Hypercalcemia refers to high levels of calcium in the blood, but a positive Chvostek sign is not indicative of hypercalcemia. In fact, hypercalcemia generally results in symptoms such as muscle weakness, fatigue, and nausea rather than the specific neuromuscular irritability seen with a positive Chvostek sign.
Choice B reason: Hypocalcemia refers to low levels of calcium in the blood and is associated with a positive Chvostek sign. The Chvostek sign is a clinical test where tapping on the facial nerve triggers twitching of the facial muscles. This occurs due to increased neuromuscular excitability caused by low calcium levels.
Choice C reason: Hypophosphatemia refers to low levels of phosphate in the blood. It is not directly associated with a positive Chvostek sign. While electrolyte imbalances can affect neuromuscular function, hypocalcemia is specifically linked to the Chvostek sign.
Choice D reason: Hypermagnesemia refers to high levels of magnesium in the blood and is not related to a positive Chvostek sign. Hypermagnesemia often causes symptoms such as muscle weakness, nausea, and hypotension rather than the neuromuscular irritability seen with a positive Chvostek sign.
