PN Comprehensive Predictor 2020 Questions
Extract:
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?
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 2 of 5
A nurse is caring for an older adult client who reports dry, itchy skin. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: A humidifier adds moisture to the air, relieving dry, itchy skin common in older adults. Frequent bathing or powder dries skin further, and bath oil is less effective long-term.
Question 3 of 5
A nurse is caring for a client who has a prescription for furosemide 40 mg PO daily. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: Furosemide causes potassium loss, so monitoring for hypokalemia is key. It's given in the morning, fluid intake shouldn't decrease, and glucose isn't directly affected.
Question 4 of 5
A nurse is assisting with the care of a client who is postoperative following a below-the-knee amputation. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: Infection (e.g., redness, fever) is a risk post-amputation, requiring monitoring. Elevation reduces swelling, not dependent positioning, and heat isn't standard.
Question 5 of 5
A nurse is caring for a client who has a new prescription for varenicline. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: Varenicline, for smoking cessation, can cause mood changes (e.g., depression), requiring monitoring. It's taken with food, oral only, and glucose isn't affected.
