A 70-year-old man with metastatic bone disease presents with fatigue, constipation, and confusion. Labs: Ca²⁺ 12.5 mg/dL (normal 8.8–10.3). The NP reflects: Excess calcium reduces nerve and muscle excitability

A 2-month-old with seizures and microcephaly is evaluated. The NP reviews genetic testing: This is PKU—an inherited enzyme defect where a single gene prevents phenylalanine metabolism. Which cellular process explains this?

A 33-year-old woman with a recent thyroidectomy reports tingling and muscle spasms. The NP notes: This looks like hypocalcemia. Low calcium lowers the threshold potential

A 23-year-old woman is hyperventilating during a panic attack. ABG: pH 7.51 (normal 7.35–7.45), PaCO₂ 28 (35–45), HCO₃⁻ 24 (22–26). The NP reflects: She’s blowing off too much CO₂

Reviewing a biopsy, the NP notes: These cells don’t look like the original tissue anymore. They’ve lost differentiation and function—classic for cancer. What process is this?

A 72-year-old dialysis patient presents with lethargy, hypotension, and absent reflexes. Mg²⁺ 4.2 mg/dL (normal 1.8–3.0). The NP considers: This isn’t low magnesium causing excitability—it’s too much magnesium accumulating because the kidneys can’t excrete it

A 36-year-old woman’s Pap smear shows cervical cells with irregular sizes, shapes, and nuclear changes. The NP reflects: This isn’t just normal adaptation—this looks disorganized and may be precancerous. Which process explains this finding?
