- A. Streptomycin sulfate
- B. rifabutin
- C. Ethambutol (Myambutol)

Tamoxifen is prescribed for the client with metastatic breast carcinoma. The nurse understands that the primary action of this medication is to:
- A. Increase DNA and RNA synthesis.
- B. Promote the biosynthesis of nucleic acids.
- C. Increase estrogen concentration and estrogen response.
- D. Compete with estradiol for binding to estrogen in tissues containing high concentrations of receptors.
Correct Answer: D
Rationale: Tamoxifen is an antineoplastic medication that competes with estradiol for binding to estrogen in tissues containing high concentrations of receptors. Tamoxifen is used to treat metastatic breast carcinoma in women and men. Tamoxifen is also effective in delaying the recurrence of cancer following mastectomy. Tamoxifen reduces DNA synthesis and estrogen response.
A primary health care provider instructs a nurse to administer a medication to a patient STAT. Which action by the nurse would be most appropriate?
- A. Insist on obtaining a written report before administering any drug.
- B. Administer the drug as ordered by the physician.
- C. Forgo obtaining the physician's order after the drug has been administered.
- D. Document the administration of the drug only after receiving the physician's order.
Correct Answer: B
Rationale: The nurse should administer the drug as instructed without a written order as it is an emergency. The nurse should, however, ensure that the physician's order is obtained after the drug has been administered. Waiting for a written order during an emergency may exacerbate the patient's condition. The nurse should complete the documentation immediately after the administration of the drug and not wait until the physician's order is received.
