Question 1 of 5
A nurse is reviewing the PT, aPTT, and INR laboratory values for a client who is experiencing an acute episode of disseminated intravascular coagulation (DIC). Which of the following laboratory results should the nurse expect?
Correct Answer: B
Rationale: In DIC, PT, aPTT, and INR are prolonged due to consumption of clotting factors.
Question 2 of 5
A nurse is caring for a client who has a pulmonary embolism and has a new prescription for enoxaparin 1.5 mg/kg/dose subcutaneously every 12 hours. The client weighs 245 lbs. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 167
Rationale: Calculation: 245 lbs ÷ 2.2 = 111.36 kg; 111.36 kg × 1.5 mg/kg = 167 mg, the correct dose.

Correct Answer: 24
Rationale: Calculation: (1,200 units/hr ÷ 25,000 units) × 500 mL = 24 mL/hr, ensuring the correct heparin dose is delivered.
