When to withhold Heparin? - The expected value for aPTT is 40 seconds. A therapeutic level of heparin increases the aPTT by a factor of 1.5 to 2, making the aPTT 60 to 80 seconds. An aPTT level of 98 is above the expected reference range, indicating that the dosage should be reduced or the infusion withheld until the aPTT returns to the therapeutic range. What does Valproic Acid treat? - Valproic acid is used to treat certain types of seizures (epilepsy). This medicine is an anticonvulsant that works in the brain tissue to stop seizures. Valproic acid is also used to treat the manic phase of bipolar disorder (manicdepressive illness), and helps prevent migraine headaches.

A nurse is caring for a child who has sickle cell anemia and is having a vaso-occlusive crisis. Which of the following interventions should the nurse implement first? - Increase IV fluids. Which of the following laboratory tests should the nurse review prior to adjusting the client's heparin? - aPTT Prior to adjusting the client's continuous heparin infusion, the nurse should review the client's activated partial thromboplastin time (aPTT). The expected reference range for the aPTT is 40 seconds. Clients who are receiving continuous heparin therapy should have an aPTT of 60 to 80 seconds, which is 1.5 to 2 times of the expected aPTT level. The nurse should increase or decrease the heparin infusion according to this value.A nurse is admitting a client who has pneumonia. The nurse should initiate which of the following isolation precautions for the client? - Droplet The nurse should initiate droplet precautions for this client by placing the client in a private room and wearing a surgical mask when caring for the client. A nurse is providing discharge teaching to a client who is to receive home oxygen therapy. Which of the following instructions should the nurse include in the teaching? - The nurse should instruct the client to check the functioning of the oxygen equipment daily. The nurse should instruct the client to wear clothing made with cotton fabrics rather than synthetic or woolen fabric when the oxygen is in use. The nurse should teach the client to apply a water-soluble lubricant to soothe irritation of the mucous membranes, because products containing oils are flammable when near oxygen. The nurse should teach the client to store full oxygen tanks in an upright position because this will prevent injury to the client and family. A nurse is assessing a client who has pulmonary edema. Which of the following findings should the nurse expect? - Pink, frothy sputum A client who has manifestations of pulmonary edema can have pink, frothy sputum due to fluid leaking across the pulmonary capillaries and into the lung tissue.

Which of the following interventions should the nurse include in the plan? - The nurse should plan to initiate a protective environment for a child who has severe immunodeficiency. The nurse should administer granulocyte colony-stimulating factor to the child to promote the production of granulocytes in the bone marrow to help fight infection. A child who has severe immunodeficiency should eat a high-calorie, high-protein diet to provide adequate nutrients to rebuild WBCs and fight infection.
