ResponseFeedback:If a patient who receives IV heparin is found to be highly anticoagulated, protamine sulfate may be prescribed. Protamine sulfate, which is a strong base, reacts with heparin, which is a strong acid, to form a stable salt, thereby neutralizing the anticoagulant effects of heparin. Protamine sulfate does not produce the same
effects for coumadin, alteplase, or ticlopidine.Question 191 out of 1 pointsWhich of the following patients will be at the greatest risk for anemia and would be the most likely candidate for epoetin alfa therapy?ResponseFeedback:Older adults who have cancer and are receiving chemotherapy are especially vulnerable to the adverse effects of anemia as a result of chemotherapy and would therefore be the most likely candidates for epoetin alfa therapy. Young adults over age 18, pregnant women, and patients with a high white blood cell count are not as vulnerable to anemia and would not require epoetin alfa therapy.Question 201 out of 1 pointsA nurse has been assigned to a 55-year-old woman who has a malignant brain tumor. The patient is receiving her first dose of carmustine. It will be critical for the nurse to observe for which of the following?ResponseFeedback:Respiratory difficulty can indicate a hypersensitivity reaction or anaphylaxis. The nurse would report any breathing difficulties immediately to the physician. If the patient does not eat or drink for more than 24 hours, the physician should be notified. Nausea and vomiting are adverse effects of the drug therapy, and an antiemetic regimen would be appropriate. Reddish urine is an adverse effect of doxorubicin, not carmustine.Question 211 out of 1 pointsA 60-year-old patient experienced a sudden onset of chest pain and shortness of breath and was subsequently diagnosed with a pulmonary embolism in the emergency department. The patient has been started on an intravenous heparin infusion. How does this drug achieve therapeutic effect?ResponseFeedback:Heparin, along with antithrombin, rapidly promotes the inactivation offactor X, which, in turn, prevents the conversion of prothrombin to thrombin. Heparin does not achieve its therapeutic effect through theexcretion or inhibition of vitamin K or by inhibiting platelet aggregation.Question 221 out of 1 pointsA middle-aged patient has received a diagnosis of GI stromal tumor following an
extensive diagnostic workup. Imatinib has been recommended as a component of the patient's drug regimen. What patient education should the nurse provide to this patient?
