CRNI Principles of Practice Questions and Answers

Question 1

A certified registered nurse infusion (CRNI) is preparing to insert a peripheral intravenous catheter for a scheduled antibiotic infusion. The patient, who is alert and oriented, states, "I've had bad experiences before, and I don't want the IV." Which of the following is the most appropriate initial action for the nurse to take?

Accepted Answer

Document the patient's refusal in the medical record and notify the prescribing provider.

Answer

The most appropriate action is to respect the patient's autonomy. An alert and oriented patient has the right to refuse treatment. The nurse's primary responsibility is to honor this refusal, document it accurately, and inform the prescribing provider so that alternative treatment plans can be considered.

Question 2

Which of the following is the primary purpose of performing antiseptic skin preparation with an approved agent before inserting a vascular access device?

Accepted Answer

To reduce the number of microorganisms on the skin and minimize the risk of infection.

Answer

The primary goal of skin antisepsis before VAD insertion is to reduce the microbial load on the skin's surface. This practice is a critical component of infection prevention and control, aimed at minimizing the risk of introducing pathogens into the bloodstream, which could lead to local site infections or bloodstream infections (BSIs).

Question 3

An infusion therapy team is implementing a quality improvement (QI) program to reduce the incidence of phlebitis. Which activity is most essential to this program?

Accepted Answer

Collecting and analyzing data on phlebitis rates, causative factors, and outcomes.

Answer

A fundamental principle of quality improvement is the use of data to identify problems, guide interventions, and measure outcomes. Collecting and analyzing data on phlebitis rates, potential causes (e.g., catheter size, dwell time, infusate), and patient outcomes provides the objective evidence needed to implement targeted, effective changes and track their success.

Question 4

A patient experiences a severe hypotensive reaction immediately after the CRNI initiates an infusion of a new antibiotic. After stopping the infusion and stabilizing the patient, the nurse discovers that the wrong medication was hung. According to the principles of professional practice, what is the nurse's priority action?

Accepted Answer

Complete an incident report and notify the nurse manager and physician.

Answer

After ensuring immediate patient safety, the nurse's priority is to report the medication error through the proper channels. This includes completing an incident report and directly communicating with the nurse manager and the responsible physician. This action promotes a culture of safety, ensures transparency, and facilitates a systematic review to prevent future occurrences.

Question 5

When selecting a site for peripheral intravenous catheter insertion in an adult patient, which of the following veins is generally the best initial choice?

Accepted Answer

The cephalic vein in the forearm.

Answer

The veins in the forearm, such as the cephalic or accessory cephalic vein, are generally preferred for peripheral IV insertion. These sites are on a flat, long bone, which acts as a natural splint, minimizing catheter movement and reducing the risk of infiltration and phlebitis. Sites in areas of flexion like the wrist or antecubital fossa should be avoided for routine infusions, as should the lower extremities in adults due to an increased risk of thrombosis.
