A client diagnosed with glomerulonephritis is at risk for developing acute kidney injury. Which of the clinical manifestations should the nurse monitor for?

Choice A reason: Hyperkalemia is a common finding in the oliguric phase of acute kidney injury due to reduced excretion of potassium by the kidneys. This electrolyte imbalance can have serious cardiac effects and should be expected and monitored in these patients.

Choice B reason: An increased glomerular filtration rate (GFR) would not be expected in the oliguric phase of acute kidney injury. Typically, GFR is decreased due to reduced kidney function during this phase.

Choice C reason: Decreased creatinine levels are not expected in acute kidney injury. Creatinine levels usually increase as kidney function declines and the body cannot adequately filter waste.

Choice D reason: Hypovolemia is not typically expected in the oliguric phase of acute kidney injury, as oliguria (reduced urine output) often indicates fluid retention rather than fluid loss.

Choice A reason: Sodium bicarbonate is used to treat metabolic acidosis and is not indicated for symptomatic bradycardia.

Choice B reason: Atropine is the first-line medication for symptomatic bradycardia. It works by blocking the vagus nerve's effects on the heart, increasing heart rate. It is commonly used in emergency settings to manage bradycardia until a more definitive treatment, such as pacemaker insertion, can be provided.

Choice C reason: Magnesium is typically used to treat torsades de pointes, a specific type of ventricular tachycardia, and is not indicated for symptomatic bradycardia.

Choice D reason: Amiodarone is an antiarrhythmic medication used to manage various types of arrhythmias, including ventricular tachycardia and fibrillation, but it is not indicated for symptomatic bradycardia.
