Question 1 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.
Question 2 of 5
A nurse is caring for a client whose arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The nurse should identify that the client is experiencing which of the following acid-base imbalances?
Correct Answer: D
Rationale: A pH of 7.3 (low) and PaCO2 of 50 mm Hg (high) indicate respiratory acidosis due to CO2 retention.
Question 3 of 5
A nurse is preparing a client for transfer to the ICU for placement of a pulmonary artery catheter. The nurse should explain to the client that this catheter is used to monitor which of the following conditions?
Correct Answer: A
