Extract:
Question 1 of 5
A nurse is reviewing laboratory results of a client who has atrial fibrillation and is taking warfarin. For which of the following results should the nurse notify the provider?
Correct Answer: C
Rationale: PT 45 seconds indicates excessive anticoagulation, increasing bleeding risk, requiring provider notification, unlike normal platelet, Hct, or Hgb values.
Question 2 of 5
A nurse in a provider's clinic is assessing a client who takes sublingual nitroglycerin for stable angina. The client reports getting a headache each time he takes the medication. Which of the following statements should the nurse make?
Correct Answer: D
Rationale: Headaches from nitroglycerin's vasodilation can be managed with mild analgesics like acetaminophen, unlike limiting doses, changing medications, or doing nothing.
Question 3 of 5
A nurse in a coronary care unit is admitting a client who has had CPR following a cardiac arrest. The client is receiving lidocaine IV at 2 mg/min. When the client asks the nurse why he is receiving that medication, the nurse should explain that it has which of the following actions?
Correct Answer: A
Rationale: Lidocaine stabilizes cardiac membranes, suppressing ventricular dysrhythmias post-cardiac arrest, not relieving pain, dissolving clots, or affecting intestinal motility.
Question 4 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.
Question 5 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).
