HEALTH SCIENCE HS101 UPDATED VERSION 2023 GRADED A + 1. A nurse is caring for a patient with a diagnosis of deep venous thrombosis (DVT). The patient has an order to receive 30 mg enoxaparin (Lovenox). Which injection site should the nurse use to administer this medication safely? A. Buttock, upper outer quadrant B. Abdomen, anterior­lateral aspect Correct C. Back of the arm, 2 inches away from a mole D. Anterolateral thigh, with no scar tissue nearby Enoxaparin (Lovenox) is a low­molecular­weight (LMW) heparin that is given as a deep subcutaneous injection in the right and left anterolateral abdomen. All subcutaneous injections should be given away from scars, lesions, or moles. Awarded 1.0 points out of 1.0 possible points. 2. 2.ID: The nurse is preparing to administer a scheduled dose of enoxaparin (Lovenox) 30 mg subcutaneously. What should the nurse do to administer this medication correctly? A. Remove the air bubble in the prefilled syringe. B. Aspirate before injection to prevent IV administration. C. Rub the injection site after administration to enhance absorption. D. Pinch the skin between the thumb and forefinger before inserting the needle. Correct The nurse should gather together or "bunch up" the skin between the thumb and the forefinger before inserting the needle into the subcutaneous tissue. The nurse should not remove the air bubble in the prefilled syringe, aspirate, nor rub the site after injection. Awarded 1.0 points out of 1.0 possible points. 3. 3.ID: The nurse is admitting a 68­year­old preoperative patient with a suspected abdominal aortic aneurysm (AAA). The medication history reveals that the patient has been taking warfarin (Coumadin) on a daily basis. Based on this history and the patient's admission diagnosis, the nurse should prepare to administer which medication? A. Vitamin K Correct B. Cobalamin C. Heparin sodium Incorrect D. Protamine sulfate Coumadin is a Vitamin K antagonist anticoagulant that could cause excessive bleeding during surgery if clotting times are not corrected before surgery. For this reason, vitamin K is given as the antidote for warfarin (Coumadin). Awarded 0.0 points out of 1.0 possible points. 4. 4.ID: The nurse is caring for a patient who has been receiving warfarin (Coumadin) and digoxin (Lanoxin) as treatment for atrial fibrillation. Because the warfarin has been discontinued before surgery, the nurse should diligently assess the patient for which complication early in the postoperative period until the medication is resumed? A. Decreased cardiac output B. Increased blood pressure C. Cerebral or pulmonary emboli Correct D. Excessive bleeding from incision or IV sites Warfarin is an anticoagulant that is used to prevent thrombi from forming on the walls of the atria during atrial fibrillation. Once the medication is terminated, thrombi could again form. If one or more thrombi detach from the atrial wall, they could travel as cerebral emboli from the left atrium or pulmonary emboli from the right atrium. Awarded 1.0 points out of 1.0 possible points
