A male client is admitted for observation because he is reporting progressively increasing fatigue over the past month and a brief episode of dizziness that occurred today. He has a history of heartburn and indigestion that he self-treats with ibuprofen and antacids. Which assessment finding should the nurse report immediately to the healthcare provider? Reference Ranges: Hemoglobin [14 to 18 g/dL (8.7 to 11.2 mmol/L)] Hematocrit [42% to 52% (0.42 to 0.52 volume fraction)] Gastric pH [1.5 to 3.5]

A) Hematocrit 42% (0.42 volume fraction): This value is within the normal range for hematocrit, indicating that the client’s blood volume and concentration are likely stable at this time. B) Gastric pH 2.0: A gastric pH of 2.0 is within the normal range for gastric acidity, indicating that the stomach is functioning properly in terms of acid production. C) Positive guaiac of stool: This finding is significant as it suggests the presence of gastrointestinal bleeding, which could be a consequence of the client's use of ibuprofen. Given the client's increasing fatigue and dizziness, which may indicate potential anemia, this finding requires immediate attention from the healthcare provider. D) Hemoglobin 13 g/dL (8.07 mmol/L): While this hemoglobin level is slightly below the normal range for males, it is not as urgent as the indication of gastrointestinal bleeding. The positive guaiac test suggests an underlying issue that may need to be addressed more urgently.
