A nurse is caring for a client who is taking azathioprine to treat rheumatoid arthritis. Which of the following laboratory values indicates an adverse effect of this medication?

Choice A Reason:
The medication vial sat at room temperature for 2 hr before it was administered is correct. Medications like filgrastim typically have specific storage requirements, including temperature control. Allowing the medication vial to sit at room temperature for an extended period may compromise its stability or effectiveness, leading to potential concerns regarding medication safety. Reporting incidents related to improper medication storage is essential to ensure patient safety and prevent similar occurrences in the future.
Choice B Reason:
The client's absolute neutrophil count was 2,500/mm3 before the medication was administered. Is incorrect. A normal or adequate absolute neutrophil count (ANC) of 2,500/mm3 before administering filgrastim is not an adverse event that requires an incident report.
Choice C Reason:
The nurse flushed the client's IV line with dextrose 5% in water before and after the medication was administered. Is incorrect. Flushing the IV line with dextrose 5% in water is a standard practice and not considered an adverse event or reason for filing an incident report.
Choice D Reason:
The client had chemotherapy 12 hr before the medication was administered. Is incorrect. The timing of previous chemotherapy administration, in this case, doesn't inherently suggest an adverse event requiring an incident report.

Choice A Reason:
"I should notify my provider if my stools turn black." This is the appropriate statement. Ferrous gluconate is an iron supplement commonly prescribed to treat or prevent iron deficiency anemia. When taking iron supplements, it's common for stools to become darker or even black in color. This change in stool color is due to the iron and is generally harmless. However, it's essential to inform the healthcare provider about this change because it can also indicate bleeding in the gastrointestinal tract, which requires evaluation.
Choice B Reason:
Taking an antacid with iron supplements can interfere with iron absorption. Antacids may decrease the absorption of iron in the stomach, so it's not recommended to take them together.
Choice C Reason:
While staying upright after taking certain medications can help prevent esophageal irritation or reflux, it's not specifically required with ferrous gluconate.
Choice D Reason:
Taking iron supplements with milk is also not recommended as milk and calcium-containing products can inhibit the absorption of iron. It's generally best to take iron supplements on an empty stomach or with vitamin C to enhance absorption, unless otherwise instructed by the healthcare provider.
