Question 1 of 5
The home health nurse observes that a female client is using a topical preparation that contains echinacea to treat a canker sore. Her husband expresses concern regarding the effectiveness and safety of using herbs. How should the nurse respond?
Correct Answer: B
Rationale: Echinacea has immune-boosting properties and may help reduce the severity of canker sores. This response acknowledges its potential benefits while remaining evidence-based, addressing the husband’s concerns appropriately.
Question 2 of 5
The healthcare provider prescribes propylthiouracil (PTU) and Lugol's solution, a strong iodine solution, for a client with hyperthyroidism. How should the nurse schedule the administration of these medications?
Correct Answer: D
Rationale: Administering Lugol's solution one hour before PTU allows iodine to suppress thyroid hormone release before PTU takes effect, enhancing therapeutic outcomes in hyperthyroidism. PTU should be taken on an empty stomach, and the medications should not be given together or at bedtime without specific timing considerations.
Question 3 of 5
Which nursing intervention has priority when initiating a continuous epidural infusion with an opioid analgesic?
Correct Answer: A
Rationale: Opioid analgesics via epidural infusion can cause respiratory depression, a life-threatening risk. Applying a pulse oximeter to monitor oxygen saturation is the priority to detect early signs of respiratory compromise, ensuring client safety over other interventions.
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 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.
