MULTIPLE CHOICE

1)The nurse is caring for a postoperative patient. The nurse will anticipate administering which medication to this patient to help prevent thrombus formation caused by slow venous blood flow?

      3. Clopidogrel (Plavix)
      4. Low–molecular-weight heparin
2. A nursing student asks why the anticoagulant heparin is given to patients who have disseminated intravascular coagulation (DIC) and are at risk for excessive bleeding. The nurse will explain that heparin is used in this case for which reason?
   1. 1. To decrease the risk of venous thrombosis
      2. To dissolve blood clots as they form
      3. To enhance the formation of fibrous clots
      4. To preserve platelet function
3. A patient has been receiving intravenous heparin. When laboratory tests are drawn, the nurse has difficulty stopping bleeding at the puncture site.

   1. Ask for an order for oral warfarin (Coumadin).
   2. Obtain an order for protamine sulfate.
   3. Request an order for vitamin K.
   4. Suggest that the patient receive subcutaneous heparin.
4. A patient who has received heparin after previous surgeries will be given enoxaparin sodium (Lovenox) after knee-replacement surgery. The patient asks how this drug is different from heparin. The nurse will explain that enoxaparin

1. decreases the need for laboratory tests.
2. has a shorter half-life than heparin.
3. increases the risk of hemorrhage.
4. may be taken orally instead of subcutaneously.

5. The nurse is caring for a patient who is receiving warfarin (Coumadin) and notes bruising and petechiae on the patient’s extremities. The nurse will request an order for which laboratory test?
   1. International normalized ratio (INR)
   2. Platelet level
   3. PTT and aPTT
   4. Vitamin K level
6. A patient who is taking warfarin has an international normalized ratio (INR) of 5.5. The nurse will anticipate giving
   1. fresh frozen plasm
   2. intravenous iron.
   3. oral vitamin K.
   4. protamine sulfate.
7. The nurse is teaching a patient who will begin taking warfarin (Coumadin) for atrial fibrillation. Which statement by the patient indicates understanding of the teaching?
   1. “I should eat plenty of green, leafy vegetables while taking this drug.”
   2. “I should take a nonsteroidal anti-inflammatory drug (NSAID) instead of acetaminophen for pain or fever.”
   3. “I will take cimetidine (Tagamet) to prevent gastric irritation and bleeding.”
   4. “I will tell my dentist that I am taking this medication.”
8. The nurse is assessing a patient who takes warfarin (Coumadin). The nurse notes a heart rate of 92 beats per minute and a blood pressure of 88/78 mm Hg. To evaluate the reason for these vital signs, the nurse will assess the patient’s
   1. gums, nose, and skin.
   2. lung sounds and respiratory effort.
   3. skin turgor and oral mucous membranes.
   4. urine output and level of consciousness.
9. A patient who has recently had a myocardial infarction (MI) will begin taking clopidogrel (Plavix) to prevent a second MI. Which medication will the nurse expect the provider to order as adjunctive therapy for this patient?
   1. Aspirin
   2. Enoxaparin sodium (Lovenox)
   3. Ticagrelor (Brilinta)
   4. Warfarin (Coumadin)
10. A patient is taking clopidogrel bisulfate (Plavix). When teaching this patient about dietary restrictions while taking this medication, the nurse will instruct the patient to avoid excessive consumption of which food?
    1. Garlic
    2. Grapefruit
    3. Green, leafy vegetables
    4. Red meats
11. A patient experiences a blood clot in one leg, and the provider has ordered a thrombolytic medication. The patient learns that the medication is expensive and asks the nurse if it is necessary. Which response by the nurse is correct?
    1. “The drug will decrease the likelihood of permanent tissue damage.”
    2. “This medication also acts to prevent future blood clots from forming.”
    3. “You could take aspirin instead of this drug to achieve the same effect.”
    4. “Your body will break down the clot, so the drug is not necessary.”
12. The nurse has just begun administering intravenous streptokinase (Streptase). The nurse assesses vital signs and notes a temperature of 37° C, a heart rate of 70 beats per minute, and a blood pressure of 88/58 mm Hg. The nurse will contact the provider to
    1. request an adjustment of the streptokinase dose.
    2. request an order for aminocaproic acid (Amicar).
    3. request epinephrine to prevent anaphylaxis.
    4. report potential hemorrhage in this patient.
13. The nurse is caring for a postoperative patient who is receiving alteplase tPA (Activase) after developing a blood clot. The nurse notes a heart rate of 110 beats per minute and a blood pressure of 90/60 mm Hg. The nurse will perform which action?
    1. Ask the patient about itching or shortness of breath.
    2. Assess the surgical dressing for bleeding.
