Extract:
Question 1 of 5
A 16-year-old adolescent with acute myelocytic leukemia is receiving chemotherapy via an implanted medication port at the outpatient oncology clinic. Which action should the nurse implement when the infusion is complete?
Correct Answer: C
Rationale: Flushing the mediport with saline and heparin prevents clot formation, maintaining patency for future use, which is a standard post-infusion procedure.
Question 2 of 5
When administering indomethacin to a premature infant who has patent ductus arteriosus, the nurse should anticipate which outcome?
Correct Answer: C
Rationale: Indomethacin promotes closure of the patent ductus arteriosus, reducing the cardiac murmur associated with the abnormal blood flow.
Question 3 of 5
A 4-month-old girl is brought to the clinic by her mother because she has had a cold for 2 to 3 days and woke up this morning with a barking cough and difficulty breathing. Which additional assessment finding should alert the nurse that the child is in acute respiratory distress?
Correct Answer: D
Rationale: Flaring of the nares indicates increased respiratory effort and accessory muscle use, a clear sign of acute respiratory distress in infants.
Question 4 of 5
The healthcare provider prescribes amoxicillin-clavulanic acid suspension 300 mg by mouth (PO) three times daily (TID) for a child with a lower respiratory infection. The bottle is labelled, 250 mg/5 mL. How many mL should the nurse administer in a single dose? (Enter numeric value only.)
Correct Answer:
Rationale:
To calculate the volume: 300 mg / (250 mg/5 mL) = 300 mg / 50 mg/mL = 6 mL per dose.
Question 5 of 5
To maintain patency of the ductus arteriosus, the nurse administers a prescribed dose of prostaglandin intravenously (IV) to a week-old infant diagnosed with transposition of the great vessels. Based on which finding should the nurse stop the medication administration immediately?
Correct Answer: A
Rationale: A heart rate of 50 beats/minute indicates bradycardia, a serious adverse effect of prostaglandin, requiring immediate cessation of the medication.
