What is the probable cause of these findings?Hyperphosphatemia Hyperuricemia Hypocalcemia Hyperkalemia Hypocalcemia A patient with sepsis develops petechiae, ecchymosis, mucosal oozing, hematuria, and a prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT). What is the most likely cause of these findings?Sickle cell anemia (SCA) Tumor lysis syndrome (TLS) Disseminated intravascular coagulation (DIC) Heparin-induced thrombocytopenia (HIT) Disseminated intravascular coagulation (DIC) A patient has idiopathic thrombocytopenia purpura (ITP).Which nursing intervention would be necessary?Administer all parenteral medications via the intramuscular route Group nursing care to allow for longer periods of rest Initiate bleeding precautions Use a firm-bristled toothbrush Initiate bleeding precautions

A patient has just been diagnosed with heparin-induced thrombocytopenia (HIT). Which action should be initiated first? initiate first?Provide the patient information on HIT Avoid all unnecessary venipunctures Initiate antiembolism stockings Remove all heparin-containing substances Remove all heparin-containing substances Which laboratory values would be most suggestive of the presence of severe thrombocytopenia?Platelet count of 50,000/mm3 Platelet count of 100,000/mm3 Platelet count of 200,000/mm3 Platelet count of 17,000/mm3 Platelet count of 17,000/mm3 A nursing student asks a nurse to explain why his patient has elevated D-dimers and what it means. Which response indicates the nurse understood the explanation?"D-dimers appear in the blood if clots are being dissolved." "D-dimers are signs of increased bleeding activity caused by heparin therapy." "D-dimers appear when fibrin is activated." "D-dimers are damaged, fragmented red blood cells." "D-dimers appear in the blood if clots are being dissolved." The nurse observes two coworkers verifying a unit of blood at the desk before administering it to the patient.What is the appropriate response?"Hospital policy and the national patient safety goals say that blood verification should be done at the bedside, not the desk." "Do you need any help with that?" "Why is he getting another unit already? Didn't you just hang one 2 hours ago?" "Did you check the hemoglobin and hematocrit before giving this unit?" "Hospital policy and the national patient safety goals say that blood verification should be done at the bedside, not the desk." A nurse is reviewing a patient's hematology report and notes that platelets have dropped from 200,000 to 100,000 in less than 24 hours. The care plan needs to be modified to include which of the following interventions?(Select all that apply.) Encourage ambulation.Avoid fresh fruits and vegetables.Avoid rectal temperatures and intramuscular injections.Monitor laboratory work.Avoid vigorous toothbrushing.Avoid rectal temperatures and intramuscular injections.Monitor laboratory work.Avoid vigorous toothbrushing.

A patient on heparin therapy has a sudden decrease in platelet count from 300,000 to 150,000. Which interventions does the nurse anticipate? (Select all that apply.) Removal of heparin-coated central lines Changing out the heparinized flush bag on the arterial line for plain normal saline Obtaining latex-free supplies because of a cross-allergic response Notifying the health care practitioner for sudden changes in level of consciousness Adding heparin to intravenous (IV) flushes for capped off IV ports Removal of heparin-coated central lines Changing out the heparinized flush bag on the arterial line for plain normal saline Notifying the health care practitioner for sudden changes in level of consciousness A nurse is drawing blood from a patient on radiation therapy for a lung tumor and notices that the arm with the tourniquet is flapping around at rest. The patient has been complaining of nausea, vomiting, and diarrhea but has gained 2 lb since yesterday. Laboratory results show potassium and phosphorus levels are elevated. Which problems are the highest priority nursing diagnoses?(Select all that apply.) Decreased cardiac output related to alterations in decreased fluid volume.Excess fluid volume related to kidney dysfunction Alteration in elimination related to medication administration Risk for infection Decreased cardiac output related to alterations in decreased fluid volume.Excess fluid volume related to kidney dysfunction
