Extract:
Question 1 of 5
The nurse is reviewing labs on a client receiving IV heparin and notes an INR of 4.6. Which order by the health care provider does the nurse anticipate?
Correct Answer: B
Rationale: Protamine sulfate is the antidote for heparin overdose, appropriate for an elevated INR indicating excessive anticoagulation.
Question 2 of 5
A child weighing 20 kg is to receive 45 mg/kg of amoxicillin per day in a divided dose every 12 hours. The oral suspension contains 250 mg/5 mL. How many milliliters should the child receive in each dose? Record your answer using a whole number.
Correct Answer: 9
Rationale: Daily dose = 45 mg/kg X 20 kg = 900 mg/day. Divided every 12 hours = 450 mg/dose. Suspension is 250 mg/5 mL, so 450 mg X (5 mL/250 mg) = 9 mL/dose.
