Question 1 of 5
A client receives a prescription for ciprofloxacin 400 mg intravenously (IV) every 12 hours to be infused over an hour. The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (DW) 200 mL. The nurse should program the infusion pump to deliver how many mL/hr? (Enter numerical value only.)
Correct Answer: 200
Rationale: The IV bag contains 200 mL of solution to be infused over 1 hour. Infusion rate =
Total volume (mL) / Infusion time (hours) = 200 mL / 1 hour = 200 mL/hr.
Question 2 of 5
A client with peptic ulcer disease receives a new prescription for cimetidine. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: D
Rationale: Smoking exacerbates peptic ulcer disease, and reducing to a pack per day is insufficient. The client should be encouraged to quit smoking entirely. Other statements reflect appropriate understanding of cimetidine administration and side effect monitoring.
Question 3 of 5
A client who received a renal transplant three months ago is readmitted to the acute care unit with signs of graft rejection. While taking the client's history, the nurse determines that the client has been self-administering St. John's Wort, an herbal preparation, on the advice of a friend. Which information is most significant about this finding?
Correct Answer: A
Rationale: St. John's Wort induces liver enzymes, reducing cyclosporine levels, an immunosuppressant critical for preventing transplant rejection. This interaction increases the risk of graft rejection, making it the most significant finding requiring immediate attention.
Question 4 of 5
The nurse is educating a client about acetaminophen. Which information provided by the client requires additional instruction by the nurse?
Correct Answer: D
Rationale: Taking additional acetaminophen doses as needed is dangerous due to the risk of liver toxicity from exceeding the maximum daily dose. The client needs instruction to adhere to prescribed dosing and consult the provider before adjusting doses.
Question 5 of 5
A client with eczema receives a prescription for betamethasone cream. Which client statement indicates to the nurse that further teaching is needed?
Correct Answer: B
Rationale: Covering the site with an occlusive dressing can increase betamethasone absorption and side effects, and should only be done under specific medical guidance. This statement requires further teaching to ensure safe use.
