Extract:
Question 1 of 5
When administering ceftriaxone sodium IV to a client before surgery, which assessment finding requires immediate intervention by the nurse?
Correct Answer: B
Rationale: Stridor indicates airway obstruction, a potential anaphylactic reaction to ceftriaxone, requiring immediate intervention. Nausea, headache, and pruritus are less urgent.
Question 2 of 5
A client is receiving IV vancomycin and the nurse plans to draw blood for a peak and trough to determine the serum level of the medication. Which collection times provide the best determination of these levels?
Correct Answer: A
Rationale: Vancomycin trough levels are measured 30 minutes before the next dose to assess the lowest concentration, ensuring therapeutic levels. Peak levels, though less commonly monitored, are taken immediately after infusion to capture the highest concentration. Other timings are less accurate for these purposes.
Question 3 of 5
The nurse is administering the angiotensin II receptor antagonist valsartan. Which physiological response causes its therapeutic effect?
Correct Answer: C
Rationale: Valsartan blocks angiotensin II, causing vasodilation to lower blood pressure. It doesn’t affect heart rate (chronotropic), cause diuresis, or act sympatholytically.
Question 4 of 5
A male client reports to the nurse that he is experiencing gastrointestinal (GI) distress from a high dose of a corticosteroid and is planning to stop taking the medication. In response to the client's statement, which nursing action is most important for the nurse to implement?
Correct Answer: B
Rationale: Abruptly stopping corticosteroids risks adrenal insufficiency. Advising gradual tapering is critical. Assessing other effects, taking with food, or reviewing dosing are secondary.
Question 5 of 5
An increase in which serum lab value indicates to the nurse that a prescription for atorvastatin is having the desired effect for a client at risk for coronary artery disease?
Correct Answer: D
Rationale: Atorvastatin lowers LDL and raises HDL to reduce coronary artery disease risk. An increase in HDL indicates a beneficial effect. Increased LDL, PT, or CK (indicating muscle damage) are not desired.
