Question 1 of 5

A nurse is assisting with the care of a client who is receiving a continuous IV infusion of potassium chloride. Which of the following actions should the nurse take?

A. Monitor the client's cardiac rhythm hourly. B. Change the IV site every 24 hr. C. Administer the infusion at a rate of 50 mL/hr. D. Flush the IV line with heparin every 4 hr.

Correct Answer: A

Rationale: Potassium chloride can cause arrhythmias, requiring cardiac monitoring. Site changes are less frequent, rate depends on orders (typically 10-20 mEq/hr), and heparin isn't routine.

Question 2 of 5

A nurse is reinforcing teaching with a client who has a new prescription for methotrexate. Which of the following statements should the nurse include?

A. You should take this medication with a full glass of milk. B. You might notice an increase in your energy levels. C. This medication might cause mouth sores. D. You should avoid drinking alcohol while taking this medication.

Correct Answer: C

Rationale: Methotrexate can cause mouth sores, a side effect to monitor. Milk isn't required, energy may decrease, and alcohol avoidance is true but not the focus here.

Question 3 of 5

A nurse is assisting with the care of a client who is receiving a continuous IV infusion of potassium chloride. Which of the following actions should the nurse take?

A. Monitor the client's cardiac rhythm hourly. B. Change the IV site every 24 hr. C. Administer the infusion at a rate of 50 mL/hr. D. Flush the IV line with heparin every 4 hr.

Correct Answer: A

Rationale: Potassium chloride can cause arrhythmias, especially if infused too quickly, so hourly cardiac monitoring is essential. Site changes are typically every 72-96 hours, the rate depends on orders (usually 10-20 mEq/hr), and heparin isn't routinely used.

Question 4 of 5

A nurse is reinforcing teaching with a client who has a new prescription for methotrexate. Which of the following statements should the nurse include?

A. You should take this medication with a full glass of milk. B. You might notice an increase in your energy levels. C. This medication might cause mouth sores. D. You should avoid drinking alcohol while taking this medication.

Correct Answer: C

Rationale: Methotrexate can cause mucositis, leading to mouth sores, a common side effect to monitor. Milk isn't required, energy may decrease due to fatigue, and while alcohol avoidance is advised, mouth sores are a more immediate concern.

Question 5 of 5

A nurse is caring for a client who has a prescription for captopril. Which of the following actions should the nurse take?

A. Administer the medication via rapid IV push. B. Monitor the client for signs of a cough. C. Dilute the medication in dextrose 5% in water. D. Instruct the client to take the medication once per week.

Correct Answer: B

Rationale: Captopril, an ACE inhibitor, commonly causes a persistent dry cough, requiring monitoring and reporting if severe. It's an oral medication, not IV, and taken daily or as prescribed, not weekly.
