Answer to Question 2
Correct Answer: 2
Rationale 1: If drawn immediately, the aPTT will reflect the level from the lower dosage.
Rationale 2: The most accurate representation of aPTT from the new rate will occur at least 6 hours after a rate increase.
Rationale 3: At 1530, the aPTT will reflect a mix of the old rate and the new rate.
Rationale 4: Waiting until 0800 the next morning is dangerous because the heparin dose may be too high.
