The nurse is reviewing lab data of a Stage 4 breast cancer patient. Which lab data may indicate further metastasis?

Choice A reason: Respiratory depression is not a typical finding associated with anemia; it is more related to respiratory or central nervous system issues.

Choice B reason: Intense abdominal pain is not a common symptom of anemia and would likely indicate other medical conditions.

Choice C reason: Bradycardia, or slow heart rate, is not commonly associated with anemia. Anemia usually causes tachycardia, or a fast heart rate, as the body attempts to compensate for the reduced oxygen-carrying capacity of the blood.

Choice D reason: Dyspnea on exertion is a common symptom of anemia, as the reduced number of red blood cells leads to decreased oxygen delivery to the tissues, causing shortness of breath during activities.

Choice A reason: A urine output of 18 mL/hr is significantly lower than the normal range (typically around 0.5-1 mL/kg/hr), indicating possible renal hypoperfusion, an early sign of shock.

Choice B reason: While blood pressure is an important indicator, it may not drop until later stages of shock.

Choice C reason: Lethargy can be a sign of shock, but it is a more subjective and later symptom compared to the objective measure of urine output.

Choice D reason: An elevated pulse is a compensatory mechanism in shock, but it is not as specific an early indicator as a decrease in urine output.
