Chapter 31 : Caring for Clients With Disorders of the Hematopoietic System Questions
Question 1 of 5
The nurse is instructing the client with sickle cell disease about the use of an inhaled vasodilator that may reduce sickling. What medication is the nurse instructing the client about?
Correct Answer: B
Rationale: Inhaled nitric oxide-not nitrous oxide (laughing gas), a vasodilating agent- is believed to reduce sickling by promoting the binding of oxygen to hemoglobin. It is being used in the form of handheld inhalers to abort or relieve pain experienced during sickle cell crises. Betamethasone is a corticosteroid, and terbutaline is not used as an inhaler.
Question 2 of 5
The nurse is admitting a client with Cooley's anemia to the hospital with a hemoglobin of 6.2 g/dL and hematocrit of 26%. What does the nurse document about the client's skin?
Correct Answer: A
Rationale: Clients with Cooley's anemia, a severe form of beta-thalassemia, exhibit symptoms of severe anemia and a bronzing of the skin caused by hemolysis of erythrocytes. The client is not jaundiced, ruddy, or pale with this disorder.
Question 3 of 5
The nurse is assigned to care for a client with polycythemia vera. When the nurse encourages the client to drink 3 L of fluid per day, the client states, 'Why do I have to drink so much?' What is the best response by the nurse?
Correct Answer: B
Rationale: The client should be advised to drink 3 quarts (or liters) per day. Adequate hydration promotes venous return and ensures sufficient urine production. Informing the client that the healthcare team does not want them to get dehydrated does not address the rationale that the client requires. Fluid hydration will not help the heart beat regularly or more effectively and it will not help to restrict blood circulation.
Question 4 of 5
The nurse is instructing the client with polycythemia vera how to perform isometric exercises such as contracting and relaxing the quadriceps and gluteal muscle during periods of inactivity. What does the nurse understand is the rationale for this type of exercise?
Correct Answer: D
Rationale: Isometric exercise induce contraction of skeletal muscle so that it compresses the walls of veins and increases the circulation of venous blood as it returns to the heart. Isometric exercises do not have an aerobic effect and should not increase the heart rate; although, it may increase blood pressure. Isometric exercise does not decrease the workload of the heart. Arterial flow moves blood flow away from the heart after being oxygenated.
Question 5 of 5
A client with multiple myeloma is complaining of severe pain when the nurse comes in to give a bath and change position. What is the priority intervention by the nurse?
Correct Answer: C
Rationale: When pain is severe, the nurse delays position changes and bathing until an administered analgesic has reached its peak concentration level and the client is experiencing maximum pain relief. Pain medication should never be delayed to assist in the control of the level of pain. Pain will not be relieved by a bath and clean sheets, only analgesics at this point in the client's illness.
