Which of the following responses by a patient who is on anticoagulant therapy indicates the need for further teaching?
- A. I can still have a glass of wine with my dinner.
- B. For pain relief I will take ibuprofen.
- C. I take my pills at two o'clock every day.
- D. I will use an electric razor for shaving.
Correct Answer: B
Rationale: Patients on anticoagulant therapy should avoid all NSAIDs; therefore ibuprofen should not be taken for pain relief. It is acceptable to have an alcohol intake of a glass of wine daily. It is important that medications be taken at the same time every day. Patients are taught to avoid the use of a straight razor.

Several hours after an open surgical repair of an abdominal aortic aneurysm, the patient develops a urinary output of 20 mL/hour for 2 hours. Which of the following prescriptions should the nurse anticipate?
- A. An additional antibiotic
- B. White blood cell (WBC) count
- C. Decrease in IV infusion rate
- D. Blood urea nitrogen (BUN) level
Correct Answer: D
Rationale: The decreased urine output suggests decreased renal perfusion, and monitoring of renal function is needed. There is no indication that infection is a concern, so antibiotic therapy and a WBC count are not needed. The IV rate may be increased because hypovolemia may be contributing to the patient's decreased urinary output.
The nurse is assessing a patient with possible peripheral artery disease (PAD) and obtains a brachial BP of 140/80 and an ankle pressure of 110/70. The nurse calculates the patient's ankle-brachial index (ABI) as
Correct Answer: 0.78 or 0.79
Rationale: The ABI is calculated by dividing the ankle systolic BP by the brachial systolic BP (110/140 â?? 0.78 or 0.79).
A patient with a venous thromboembolism (VTE) is started on enoxaparin and warfarin. The patient asks the nurse why two medications are necessary. Which of the following responses by the nurse is accurate?
- A. Administration of two anticoagulants reduces the risk for recurrent venous thrombosis.
- B. Enoxaparin will start to dissolve the clot, and warfarin will prevent any more clots from occurring.
- C. The enoxaparin will work immediately, but the warfarin takes several days to have an effect on coagulation.
- D. Because of the potential for a pulmonary embolism, it is important for you to have more than one anticoagulant.
Correct Answer: C
Rationale: Low-molecular-weight heparin (LMWH) such as enoxaparin has an immediate effect on coagulation and is used until warfarin reaches therapeutic levels, which takes several days.
A patient in the outpatient clinic has a new diagnosis of peripheral artery disease (PAD). Which of the following medication categories should the nurse plan to include when providing patient teaching about PAD management?
- A. Statins
- B. Vitamins
- C. Thrombolytics
- D. Anticoagulants
Correct Answer: A
Rationale: Current research indicates that statin use by patients with PAD improves multiple outcomes. There is no research that supports the use of the other medication categories in PAD.
Which of the following actions by a nurse who is administering fondaparinux to a patient with venous thromboembolism (VTE) indicates that more education about the medication is needed?
- A. The nurse avoids rubbing the injection site after giving the medication.
- B. The nurse injects the medication into the abdominal subcutaneous tissue.
- C. The nurse fails to assess the partial thromboplastin time (PTT) before administration of the medication.
- D. The nurse ejects the air bubble in the syringe before administering the medication.
Correct Answer: D
Rationale: The air bubble is not ejected before giving fondaparinux. The other actions by the nurse are appropriate.
