Extract:
Question 1 of 5
A nurse is caring for a client who has quadriplegia from a spinal cord injury and reports having a severe headache. The nurse obtains a blood pressure reading of 210/108 mm Hg and suspects the client is experiencing autonomic dysreflexia. Which of the following actions should the nurse take first?
Correct Answer: D
Rationale: Placing the client in a high-Fowler's position reduces blood pressure in autonomic dysreflexia by promoting venous pooling.
Question 2 of 5
A nurse is reviewing the laboratory values of a client who has respiratory acidosis. Which of the following findings should the nurse expect?
Correct Answer: A
Rationale: Elevated PaCO2 (50 mm Hg) is expected in respiratory acidosis due to CO2 retention.
Question 3 of 5
A nurse is reviewing the arterial blood gas values for a client. The pH is 7.32, PaCO2 is 48 mm Hg and the HCO3 is 23 mEq/L. The nurse should recognize that these findings indicate which of the following acid-base imbalances?
Correct Answer: A
Rationale: pH 7.32 (low), PaCO2 48 mm Hg (high), and normal HCO3 indicate respiratory acidosis from CO2 retention.
Question 4 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 5 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.
