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 (D5W) 200 mL. The nurse should program the infusion pump to deliver how many mL/hr? (Enter numerical value only.)
Correct Answer: 200
Rationale: Infusion rate = 200 mL ÷ 1 hour = 200 mL/hr. The pump should be set to deliver 200 mL/hr to infuse the entire dose over one hour.
Question 2 of 5
The nurse is caring for a client who takes methotrexate for rheumatoid arthritis and receives a prescription for adalimumab. Which instructions should the nurse provide the client?
Correct Answer: B
Rationale: Adalimumab, an immunosuppressant, increases infection risk. Avoiding crowds and sick individuals minimizes exposure, protecting the client’s compromised immune system. Eye exams, chest x-rays, or vaccinations are not specifically required for adalimumab initiation.
Question 3 of 5
The nurse is teaching a client how to use an inhaler device. Which client statement indicates to the nurse that the client understands the instructions?
Correct Answer: B
Rationale: Rinsing the mouth after inhaler use, especially with corticosteroids, prevents oral thrush by removing residual medication. Bedtime-only use, meal timing, or caffeine limits are incorrect and unrelated to proper inhaler technique.
Question 4 of 5
A glucagon emergency kit is prescribed for a client with type 1 diabetes mellitus. When should the nurse instruct the client and family that glucagon needs to be administered?
Correct Answer: A
Rationale: Glucagon raises blood glucose in severe hypoglycemia (e.g., unconsciousness), preventing complications. It’s not for hyperglycemia, sick days, or diabetic ketoacidosis, which require insulin and other treatments.
Question 5 of 5
The healthcare provider prescribes magnesium sulfate 300 mg/hour IV. The IV bag contains magnesium sulfate 4 grams in dextrose 5% in water (D5W) 500 mL. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 37.5
Rationale: Convert 4 grams to 4000 mg. Infusion rate = (300 mg/hr) ÷ (4000 mg/500 mL) = 300 × 500 ÷ 4000 = 37.5 mL/hr. The pump should be set to 37.5 mL/hr.
