Question 1 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: Methotrexate and adalimumab suppress the immune system, increasing infection risk. Avoiding crowds and sick individuals reduces exposure to pathogens, making this the most critical instruction to prevent serious infections.
Question 2 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 3 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: B
Rationale: Glucagon is used to treat severe hypoglycemia when a client cannot consume oral glucose due to altered consciousness or inability to swallow. It rapidly increases blood glucose levels, making it critical for emergency management of severe hypoglycemic episodes.
Question 4 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 (DW) 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: Concentration = 4000 mg / 500 mL = 8 mg/mL. Infusion rate = Prescribed dose (300 mg/hour) / Concentration (8 mg/mL) = 37.5 mL/hour.
Question 5 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.
