A female child, age 2, is brought to the emergency department after ingesting an unknown number of aspirin tablets about 30 minutes earlier. On entering the examination room, the child is crying and clinging to the mother. Which data should the nurse obtain first?

Correct Answer: A

Rationale: In this situation, the priority data the nurse should obtain first is the vital signs including heart rate, respiratory rate, and blood pressure of the child. This information will help assess the child's current physiological status and potential effects of ingesting the aspirin. Aspirin overdose in children can lead to serious complications such as metabolic acidosis, respiratory distress, and cardiovascular instability. Monitoring the vital signs will provide crucial information to guide appropriate interventions and determine the severity of the child's condition. Height and weight (option D) are important for routine assessments but not the priority in this urgent situation. Recent exposure to communicable diseases (option B) and number of immunizations received (option C) are not relevant to the immediate management of the child's aspirin ingestion.

Correct Answer: B

Rationale: Antacids can interfere with the absorption of iron from ferrous sulfate. Therefore, it is important to take these medications at least 2 hours apart to ensure proper absorption of the iron supplement. Taking them together can reduce the effectiveness of the ferrous sulfate therapy in treating the iron deficiency. It is not necessary to avoid taking an antacid altogether, but timing is crucial to optimize the benefits of both medications.

Correct Answer: A

Rationale: Referral to an obstetrician is necessary for proper evaluation and management.

Correct Answer: A

Rationale: Elevated LDH levels are strongly associated with aggressive disease and poor prognosis.

Correct Answer: B

Rationale: Bloody diarrhea is a key sign of NEC, indicating intestinal injury.
