A nurse at a long-term care facility is assisting with teaching staff about infection control practices. Which of the following examples should the nurse include as an infection control hazard?

A staff member places a midstream urine sample in a specimen refrigerator after-collecting it.

A staff member wipes a countertop with chlorhexidine solution to clean the area following a blood spill.

A nurse uses alcohol-based antiseptic to clean his hands after talking with a client who has varicella zoster.

A nurse pours sterile 0.9% sodium chloride irrigation solution on an open pressure wound prior to collecting a specimen for culture

Answer and Explanation

The Correct Answer is D

A. A staff member places a midstream urine sample in a specimen refrigerator after collecting it:

This is a proper practice. Refrigerating the sample after collection helps preserve its integrity and prevents bacterial growth until it can be analyzed.

B. A staff member wipes a countertop with chlorhexidine solution to clean the area following a blood spill:

This is a proper infection control practice. Chlorhexidine is an effective disinfectant, and cleaning the area following a blood spill helps prevent the spread of infectious agents.

C. A nurse uses alcohol-based antiseptic to clean his hands after talking with a client who has varicella zoster:

This is a proper practice. Alcohol-based antiseptic is effective in killing a broad spectrum of germs, and hand hygiene is crucial, especially after contact with a client who may have an infectious condition.

D. A nurse pours sterile 0.9% sodium chloride irrigation solution on an open pressure wound prior to collecting a specimen for culture:

This is an infection control hazard. Sterile saline irrigation should not be poured onto an open wound before specimen collection, as it can introduce contaminants and interfere with the accuracy of culture results. Specimens should be collected using aseptic technique to avoid contamination.

Correct Answer is ["10"]

Explanation

To calculate the volume (mL) that the nurse should administer, you can use the following formula:

Volume (mL) = Dose (mg)/Concentration (mg/mL)

In this case:

Volume = 500 mg/(250 mg/5 mL)

First, simplify the fraction:

Volume = 500mg/50 mg/mL

Now, determine the volume:

Volume =(500 mg/50 mg/mL)×(1 mL/1mg)

Volume=10mL

Therefore, the nurse should administer 10 mL of amoxicillin oral suspension for the 500 mg PO dose, rounded to the nearest whole number.

Correct Answer is ["38"]

Explanation

To calculate the IV flow rate in drops per minute (gtt/min), you can use the following formula:

Flow Rate (gtt/min)=(Volume (mL)/Time (min)) × Drop Factor (gtt/mL)

In this case:

Flow Rate = (150 mL/hr / 60 min/hr) × 15 gtt/mL

Flow Rate=37.5gtt/min

Therefore, the nurse should set the IV flow rate to deliver approximately 38 gtt/min for the dextrose 5% in water IV infusion at 150 mL/hr, rounded to the nearest whole number.
