During new employee orientation, a nurse is explaining how to prevent IV infections. Which of the following statements by an orientee indicates understanding of the preventive strategies?

"As long as I am working with the same client, I can use the same IV catheter for my second insertion attempt."

“I will replace any IV catheter when I suspect contamination during insertion."

“I will leave the IV catheter in place after the client completes the course of IV antibiotics."

“If my client needs to use the rest room, it would be safer to disconnect their IV infusion as long as I clean the injection port thoroughly with an antiseptic swab."

Answer and Explanation

The Correct Answer is B

A.   Using the same IV catheter for a second insertion attempt is not advisable. Once an IV catheter has been inserted, it should not be reused or reinserted in the same or a different site. If the initial insertion fails or if the catheter needs to be repositioned, a new sterile catheter should be used.
B.   If there is any suspicion of contamination during the insertion of an IV catheter, it is important to replace the catheter to prevent infection. This is crucial for maintaining sterility and reducing the risk of introducing pathogens into the patient’s bloodstream.
C.   The IV catheter should be removed once the course of IV antibiotics or any other IV therapy is completed, unless there is a specific medical reason to keep it in place. Leaving the catheter in place unnecessarily increases the risk of infection and other complications.
D.   Disconnecting the IV infusion for a client to use the restroom is not typically recommended as a standard practice. Disconnecting can introduce risks of infection and requires thorough cleaning and handling. Instead, a safer practice is to secure the IV line and allow the client to use the restroom while keeping the infusion running, or use a specialized catheter with a secure, closed system.

Correct Answer is C

Explanation

A. pH 7.35, PaCO2 40 mm Hg, HCO3-25 mEq/L: This is within normal ranges and does not indicate acidosis.
B. pH 7.32, PaCO2 47 mm Hg. HCO3-23 mEq/L: This indicates respiratory acidosis, not metabolic.
C. pH 7.3, PaCO2 36 mm Hg. HCO3- 19 mEq/L: This indicates metabolic acidosis. The pH is low (acidic), and the HCO3- (bicarbonate) is decreased. The PaCO2 is within normal limits, indicating the respiratory system is compensating for the metabolic acidosis.
D. pH 7.5, PaCO2 35 mm Hg, HCO3- 35 mEq/L: This indicates alkalosis, not acidosis.

Correct Answer is ["100"]

Explanation

To calculate the rate at which the IV pump should be set to deliver the medication, you would use the formula:

(Total Volume in mL / Time in hours) = mL/hr.

The total volume of the IV bag is 50 mL and the time frame is 0.5 hours (since 30 minutes is half an hour). So, the calculation would be 50 mL / 0.5 hours = 100 mL/hr.

Therefore, the nurse should set the IV pump to deliver 100 mL/hr to administer 500 mg of ampicillin over 30 minutes.
