Question 1 of 5
Nursing care for a client undergoing chemotherapy includes assessment for signs of bone marrow depression. Which finding accounts for some of the symptoms related to bone marrow depression?
Correct Answer: D
Rationale: Thrombocytopenia is an abnormal decrease in the number of platelets, which results in bleeding tendencies. Erythrocytosis is an abnormal increase in the number of circulating red blood cells. Leukocytosis is an increase in the number of white blood cells in the blood. Polycythemia is also an excess of red blood cells and is a synonym for erythrocytosis. With chemotherapy there is a decrease in red and white blood cells, not an increase.

The nurse is developing the teaching plan for the client who is started on amitriptyline. Which information is most appropriate to include?

A client who is newly diagnosed with Parkinson's disease and beginning medication therapy asks the nurse, 'How soon will I see improvement?' The nurse's best response is:

Question 4 of 5
The hospitalized child who has a blood lead level of 50 mcg/dL is to receive succimer 10 mg/kg oral capsule q8h for 5 days. The child weighs 20 kg. Which intervention by the student nurse should be corrected by the observing nurse?
Correct Answer: A
Rationale: A: The 20-kg child should receive two capsules of succimer (Chemet), not one. Dose (mg) = 20 kg x 10 mg/kg = 200 mg. B: Succimer capsules can be opened and sprinkled on a small amount of food or in liquid to be swallowed; two 100-mg capsules = 200 mg, which is the correct dose. C: Fluids should be increased to prevent renal damage because succimer is excreted by the kidneys. D: Succimer forms a water-soluble compound with lead, allowing urinary elimination of excessive amounts of lead. Lead is removed from the blood, and theoretically some lead is removed from tissues and organs.
