Extract:
Question 1 of 5
A nurse is caring for a client who has chronic renal disease and is receiving therapy with epoetin alfa. Which of the following laboratory results would the nurse assess for to determine therapeutic effectiveness?
Correct Answer: B
Rationale: Epoetin alfa stimulates red blood cell production, increasing hemoglobin and hematocrit levels, which are monitored to assess effectiveness in treating anemia associated with chronic renal disease. Clotting factors, leukocyte count, and liver function tests (ALT & AST) are not directly affected by epoetin alfa.
Question 2 of 5
A client diagnosed with a urinary tract infection (UTI) is prescribed sulfamethoxazole/trimethoprim. Which of the following conditions below would be a contraindication for this medication?
Correct Answer: B
Rationale: Sulfamethoxazole/trimethoprim can increase potassium levels, and captopril, an ACE inhibitor, also raises potassium, increasing the risk of hyperkalemia. Uterine cancer, osteoporosis, and multiple sclerosis do not contraindicate its use.
Question 3 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 4 of 5
A nurse is caring for a client. After reviewing the information in the client's medical record, which of the following provider prescriptions should the nurse anticipate? The nurse should anticipate a provider prescription for
Correct Answer: A
Rationale: The client's painful vesicular sores on the perineum, muscle aches, chills, and history of unprotected sexual encounters suggest genital herpes, treated with acyclovir, an antiviral for herpes simplex virus. Ceftriaxone treats gonorrhea, azithromycin treats chlamydia, and fluconazole treats yeast infections, none of which align with the vesicular sores and systemic symptoms.
Question 5 of 5
A client exposed to anthrax has presented to the healthcare setting. Which of the following medications below is the treatment for this biological exposure?
Correct Answer: C
Rationale: Ciprofloxacin, a fluoroquinolone, is the recommended first-line antibiotic for treating anthrax exposure due to its efficacy against Bacillus anthracis, the bacteria causing anthrax. Amoxicillin/clavulanate is a broad-spectrum antibiotic but not preferred for anthrax. Nystatin is an antifungal and ineffective against bacterial infections. Tamoxifen is used for breast cancer and has no role in treating anthrax.
