A nurse is teaching a client about the causes of osteoporosis. The nurse should include which of the following types of medication therapy as a risk factor for osteoporosis?
Cardiac glycosides
Thyroid hormones
Anticoagulants
NSAIDs
The Correct Answer is B
Choice A reason: Cardiac glycosides are primarily used to treat heart conditions such as heart failure and atrial fibrillation. They do not typically affect bone density or contribute to osteoporosis.
Choice B reason: Thyroid hormones can increase the risk of osteoporosis, especially if taken in excess. Over-replacement of thyroid hormone can accelerate bone loss, leading to decreased bone density and increased fracture risk.
Choice C reason: Anticoagulants are used to prevent blood clots but are not generally associated with an increased risk of osteoporosis. Their primary side effects are related to bleeding and bruising.
Choice D reason: NSAIDs (nonsteroidal anti-inflammatory drugs) are used to reduce inflammation and pain. They do not typically affect bone density or contribute to osteoporosis.

Correct Answer is C
Explanation
Choice A reason: Aplastic anemia results in an increased rate of RBC destruction
Aplastic anemia does not result from an increased rate of red blood cell (RBC) destruction. Instead, it is characterized by the bone marrow’s inability to produce sufficient new blood cells, including RBCs, white blood cells, and platelets. This condition leads to pancytopenia, a deficiency of all types of blood cells.
Choice B reason: Aplastic anemia is associated with a decreased intake of iron
Aplastic anemia is not typically associated with a decreased intake of iron. Iron deficiency anemia is a different condition where the body lacks enough iron to produce hemoglobin. Aplastic anemia, on the other hand, is due to the failure of the bone marrow to produce adequate blood cells.
Choice C reason: Aplastic anemia results from decreased bone marrow production of RBCs
This statement is correct. Aplastic anemia occurs when the bone marrow fails to produce enough new blood cells. This can be due to various factors, including autoimmune disorders, exposure to toxic chemicals, certain medications, and viral infections. The decreased production of RBCs, along with other blood cells, leads to the symptoms associated with aplastic anemia.
Choice D reason: Aplastic anemia results in an inability to absorb vitamin B12
Aplastic anemia is not related to the absorption of vitamin B12. Pernicious anemia is the condition associated with an inability to absorb vitamin B12 due to a lack of intrinsic factor. Aplastic anemia is specifically related to the bone marrow’s failure to produce sufficient blood cells.
Correct Answer is ["675"]
Explanation
Step 1: Convert the client’s weight from pounds to kilograms. 198 lb ÷ 2.2 = 90 kg
Result: 90 kg
Step 2: Calculate the total daily dose of vancomycin. 15 mg × 90 kg = 1350 mg/day
Result: 1350 mg/day
Step 3: Divide the total daily dose by 2 to get the dose per administration (since it is given every 12 hours). 1350 mg/day ÷ 2 = 675 mg
Result: 675 mg
Final Answer: The nurse should administer 675 mg of vancomycin with each dose.
