A nurse is screening a client for cancer risk factors. The nurse records that the client is a 65-year-old male, clinically obese with a BMI of 31, has a history of past smoking, and drinks moderately. Which of the following is a primary risk factor for prostate cancer?

Choice A reason: Epigastric-area pain that intensifies when lying down is more commonly associated with conditions like gastroesophageal reflux disease (GERD) or pancreatitis, rather than cholecystitis.
Choice B reason: Right upper-quadrant pain radiating to the shoulder and scapula is a classic symptom of cholecystitis. This pain is due to inflammation of the gallbladder, often aggravated by fatty meals, and may radiate to the back and shoulder.
Choice C reason: Right lower-quadrant pain with rebound tenderness is typically associated with appendicitis rather than cholecystitis. Cholecystitis primarily affects the right upper quadrant.
Choice D reason: Left-flank pain with intermittent exacerbations is not characteristic of cholecystitis. It might indicate conditions related to the left kidney or other left-sided abdominal issues.

Choice A reason: Increased glomerular filtration rate (GFR) would indicate improved kidney function, which is not expected in the oliguric phase of acute kidney injury. Instead, GFR is typically reduced during this phase.
Choice B reason: Decreased creatinine level suggests better kidney function and is not consistent with acute kidney injury, where creatinine levels are usually elevated due to impaired filtration.
Choice C reason: Hypomagnesemia, or low magnesium levels, is not a typical finding in acute kidney injury. Electrolyte imbalances more commonly include elevated levels of potassium and phosphorus.
Choice D reason: Hyperkalemia, or elevated potassium levels, is a common finding in the oliguric phase of acute kidney injury due to the kidneys' inability to excrete potassium effectively. This can lead to serious complications such as cardiac arrhythmias.
