Question 1 of 5
A charge nurse is teaching a group of nurses about the differences amongst anemia treatments. For each medication listed below, click to specify the expected treatment option.
| Options | Cyanocobalamin | Folic Acid | Epogen | Ferrous Sulfate |
|---|---|---|---|---|
| Epogen for Anemia Due to CKD | ||||
| Ferrous Sulfate for Iron Deficiency Anemia | ||||
| Cyanocobalamin for Pernicious Anemia | ||||
| Folic Acid for Folate Deficiency Anemia |
Correct Answer: A,B,C,D
Rationale: Epogen (epoetin alfa) treats anemia due to chronic kidney disease by stimulating red blood cell production. Ferrous sulfate addresses iron deficiency anemia by replenishing iron stores. Cyanocobalamin (vitamin B12) treats pernicious anemia caused by B12 deficiency. Folic acid corrects folate deficiency anemia. Each medication is specific to the underlying cause of anemia.
Question 2 of 5
The nurse is administering an estrogen blocker to a client diagnosed with advanced breast cancer. Which of the following side effects will the nurse caution the client regarding?
Correct Answer: D
Rationale: Estrogen blockers like tamoxifen increase the risk of thromboembolic events (e.g., deep vein thrombosis, pulmonary embolism) due to altered clotting mechanisms. Tendon rupture, phlebitis, and lymphomas are not typical side effects.
Question 3 of 5
A nurse is teaching a client who is beginning highly active antiretroviral therapy (HAART) for HIV which includes zidovudine. The nurse should include teaching regarding which black box warning associated with this medication?
Correct Answer: A
Rationale: Zidovudine carries a black box warning for lactic acidosis, a rare but serious complication. Clients should be educated on symptoms like muscle pain and weakness. It is not associated with uterine cancer, oral candidiasis (though common in HIV), or thromboembolic events.

Physical examination
Vital signs
1400:

Question 4 of 5
A nurse is providing an Inservice to newly graduated nurses. Which of the following vaccines would the nurse label as 'live vaccines' and should be avoided by immunocompromised clients?
| Measles |
| Inactivated Polio |
| Mumps |
| Varicella |
| Rubella |
Correct Answer: A,C,D,E
Rationale: Live-attenuated vaccines (measles, mumps, rubella, varicella) contain weakened viruses and are contraindicated in immunocompromised clients due to infection risk. Inactivated polio vaccine uses killed virus, making it safe for immunocompromised individuals.

Question 5 of 5
A client with a leukemia has been placed on methotrexate. Which of the following mechanism of actions below describes this medication?
Correct Answer: C
Rationale: Methotrexate is an antimetabolite that inhibits dihydrofolate reductase, an enzyme involved in folic acid synthesis, impairing DNA synthesis critical for rapidly dividing cells like those in leukemia. It does not stop fungal growth, alter pH levels, or specifically inhibit helper T cells (a mechanism associated with immunosuppressive drugs like cyclosporine).
