Question 1 of 5
The initial treatment regimen of isoniazid, rifampin, and ethambutol is prescribed for the adolescent who has a positive tuberculin skin test. The client confides that she thinks she may be pregnant and asks if she should be taking these medications. Which rationale should be the basis for the nurse's response?
Correct Answer: D
Rationale: A: The medications do not cross the placental barrier, so treatment should not be withheld. B: Administering antituberculosis medications would not be an indication for termination of pregnancy because the medications are safe during pregnancy. C: The risk of hepatitis is slightly increased with the use of antituberculosis medications in pregnant women; however, the benefits of treatment strongly outweigh postponement of treatment. D: Infants born to women with untreated TB may be of lower birth weight, but rarely would the infant acquire congenital TB. Isoniazid (Nydrazid), rifampin (Rifadin), and ethambutol (Myambutol) are all considered safe for use in pregnancy.

Question 3 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.
Question 4 of 5
The HCP orders a digitalizing dose of digoxin 225 mcg IV now to be given to a 3-year-old. The pharmacy sends a solution of 500 mcg in 50 mL of D5W. How many mL should the nurse administer?
