The nurse is involved in a health promotion program for teenagers related to the prevention of oral cancer. Which behaviors would the nurse explain as increasing the risk for oral cancer? Select all that apply.

Choice A reason: Neutrophils at 3,000/mm might indicate an infection, but for acute appendicitis, one would expect to see a significant increase in the overall white blood cell count rather than just the neutrophils.
Choice B reason: Lymphocytes at 3,000/mm do not specifically indicate acute appendicitis. Lymphocyte counts are more commonly elevated in viral infections rather than bacterial ones like appendicitis.
Choice C reason: A WBC count of 17,000/mm is indicative of an acute bacterial infection like appendicitis. The elevated WBC count shows the body’s response to the infection, making this the most accurate indicator among the options provided.
Choice D reason: RBC at 4.2 million/mm is within the normal range and does not provide specific information related to acute appendicitis. This value is unrelated to the acute inflammatory process expected in appendicitis.

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.
