Question 1 of 5
A nurse is assessing a client who is receiving IV ciprofloxacin to treat a urinary tract infection. Which of the following findings should the nurse identify as the priority to report to the provider?
Correct Answer: C
Rationale: Tendon pain, particularly when walking, may indicate tendonitis or risk of tendon rupture, a serious adverse effect of ciprofloxacin requiring immediate attention.
Question 2 of 5
A nurse is preparing to administer dopamine 5 mcg/kg/min by continuous IV infusion to a client who weighs 220 lb. Available is 400 mg of dopamine in 250 mL of 0.9% sodium chloride. The nurse should set the IV pump to deliver how many mL/hr?
Correct Answer: A
Rationale: Convert 220 lb to 100 kg, calculate dose (500 mcg/min = 0.5 mg/min), then infusion rate: (0.5 mg/min / 400 mg) * 250 mL * 60 min/h = 18.8 mL/hr.
Question 3 of 5
A nurse who is caring for a preschooler should question a prescription for which of the following antibiotics?
Correct Answer: B
Rationale: Tetracycline is contraindicated in children under 8 years due to the risk of permanent tooth discoloration and damage to developing bones.
Question 4 of 5
A nurse is caring for a client who has a new prescription for metformin. Which of the following laboratory results should the nurse evaluate prior to administering the first dose?
Correct Answer: B
Rationale: Before administering the first dose of metformin, the nurse should evaluate the client's creatinine level. Metformin is primarily excreted by the kidneys, and its clearance depends on renal function. Elevated creatinine levels indicate impaired kidney function, which can lead to metformin accumulation and increase the risk of lactic acidosis.
