Chapter 26 : Coagulation Modifier Drugs Questions
Question 1 of 5
When administering heparin subcutaneously, the nurse will follow which procedure?
Correct Answer: D
Rationale: A 1/2- to 5/8-inch 25- to 27-gauge needle is the correct needle to use for a subcutaneous heparin injection. Aspirating before the injection and massaging the site after the injection encourage hematoma formation at the injection site. Injection sites need to be rotated with each injection.
Question 2 of 5
A patient has been instructed to take one enteric-coated low-dose aspirin a day as part of therapy to prevent strokes. The nurse will provide which instruction when providing patient teaching about this medication?
Correct Answer: C
Rationale: Enteric-coated aspirin is best taken with 6 to 8 ounces of water and with food to help decrease gastrointestinal upset. Enteric-coated tablets should not be crushed. Risk for bleeding increases with aspirin therapy, even at low doses.
Question 3 of 5
A patient will be receiving a thrombolytic drug as part of the treatment for acute myocardial infarction. The nurse explains to the patient that this drug is used for which purpose?
Correct Answer: C
Rationale: Thrombolytic drugs lyse, or dissolve, thrombi. They are not used to prevent further clot formation or to control bleeding. As a result of dissolving of the thrombi, chest pain may be relieved, but that is not the primary purpose of thrombolytic therapy.
Question 4 of 5
A patient is receiving heparin therapy as part of the treatment for a pulmonary embolism. The nurse monitors the results of which laboratory test to check the drug's effectiveness?
Correct Answer: B
Rationale: Ongoing aPTT values are used to monitor heparin therapy. PT/INR is used to monitor warfarin therapy. The other two options are not used to monitor anticoagulant therapy.
Question 5 of 5
The nurse notes in the patient's medication orders that the patient will be starting anticoagulant therapy. What is the primary goal of anticoagulant therapy?
Correct Answer: C
Rationale: Anticoagulants prevent thrombus formation but do not dissolve or stabilize an existing thrombus, nor do they dilate vessels around a clot.
