ATI Pharmacology Exam 2 Questions
Extract:
Question 1 of 5
A nurse is caring for a client who is postoperative following hip arthroplasty. The nurse should anticipate which of the following medications for this client?
Correct Answer: D
Rationale: Enoxaparin prevents DVT post-hip arthroplasty, unlike aspirin (less effective), alteplase (thrombolytic), or clopidogrel (arterial thrombosis).
Question 2 of 5
A nurse is assessing a client prior to administering atenolol. Which of the following findings should prompt the nurse to withhold the medication?
Correct Answer: B
Rationale: Atenolol, a beta-blocker, lowers heart rate. A heart rate of 46/min indicates bradycardia, warranting withholding to avoid further reduction, unlike other normal findings.
Question 3 of 5
A nurse is teaching a client who has angina pectoris about starting therapy with sublingual (SL) nitroglycerin tablets. The nurse should include which of the following instructions regarding how to take the medication?
Correct Answer: B
Rationale: Sublingual nitroglycerin is taken at chest pain onset for rapid relief, not with water, every 15 minutes, or routinely after meals.
Question 4 of 5
A nurse is caring for a client who has a central venous catheter and reports hearing a gurgling sound on the side of the catheter insertion. Which of the following complications should the nurse suspect?
Correct Answer: C
Rationale: A gurgling sound suggests air entry from catheter dislodgment, a serious issue requiring immediate attention, unlike occlusion, migration, or rupture.
Question 5 of 5
A nurse is receiving a client who is immediately postoperative following hip arthroplasty. Which of the following medications should the nurse plan to administer for DVT prophylaxis?
Correct Answer: B
Rationale: Enoxaparin, a low-molecular-weight heparin, is effective for DVT prophylaxis post-hip arthroplasty due to rapid onset, unlike warfarin, aspirin, or heparin infusion.
