NCLEX PN Practice Test Questions
Extract:
Question 1 of 5
The nurse is observing a staff member preparing regular insulin and NPH insulin in 1 syringe. The nurse should intervene if the staff member is observed
Correct Answer: A
Rationale: When mixing regular and NPH insulin, regular (clear) insulin is drawn first to prevent contamination with NPH (cloudy) insulin, which could alter its action. Drawing NPH after regular (
A) is incorrect and requires intervention. Injecting air into vials (
B) follows the same order (NPH then regular), which is correct. Needle contact with the vial (
C) is poor technique but less critical than incorrect insulin order.
Question 2 of 5
The nurse is reinforcing teaching of proper foot care to a client with diabetes mellitus. Which statement by the client indicates the need for further teaching?
Correct Answer: D
Rationale: Sandals (
D) expose feet to injury, increasing infection risk in diabetes. Lanolin (
A), avoiding heating pads (
B), and testing water (
C) are correct to prevent skin breakdown and burns.
Question 3 of 5
The nurse is giving preoperative medication to an adult who is scheduled for surgery. The client says to the nurse that she does not want to have a transfusion during surgery because it is against her religion. The client has signed a consent form for surgery. How should the nurse respond?
Correct Answer: C
Rationale: An addendum to refuse transfusions respects the client's religious beliefs, ensuring informed consent. Other responses dismiss her autonomy or delay care.
Question 4 of 5
The nurse observes a client using a walker. Which observation indicates that the client needs more instruction?
Correct Answer: A
Rationale: Using the walker to pull up risks tipping, indicating improper use and a need for further instruction on safe walker technique.
Question 5 of 5
