The charge nurse observes a new nurse preparing to irrigate an intravenous catheter.
The new nurse has a luer-lock tipped syringe.
What action should the charge nurse take?
Prompt the nurse to apply povidone to the site.
Direct the nurse to attach the luer-lock tip to the irrigation port.
Send an unlicensed assistive personnel to gather equipment.
Instruct the nurse to use water with 5% dextrose (D5W).
The Correct Answer is B
Choice A rationale
Prompting the nurse to apply povidone to the site is not the correct action in this scenario. Povidone-iodine is an antiseptic used for skin disinfection before and after surgery. It is not typically used in the process of irrigating an intravenous catheter.
Choice B rationale
Directing the nurse to attach the luer-lock tip to the irrigation port is the correct action. A luer-lock syringe is commonly used in medical procedures, including the irrigation of an intravenous catheter. The luer-lock tip provides a secure connection to prevent leaks and ensure that the irrigation solution is delivered directly to the catheter.
Choice C rationale
Sending an unlicensed assistive personnel to gather equipment is not the most appropriate action in this scenario. The new nurse has already gathered the necessary equipment for the procedure.
Choice D rationale
Instructing the nurse to use water with 5% dextrose (D5W) is not the correct action. D5W is a type of intravenous fluid used to correct dehydration and provide calories to the patient. It is not typically used for irrigating an intravenous catheter.

Correct Answer is D
Explanation
The correct answer is Choice D.
Choice D rationale: Keeping the nails trimmed short is crucial for a child with eczema because it minimizes the damage done when the child scratches their skin. Short nails reduce the risk of breaking the skin and causing infections or further irritation, which can exacerbate eczema symptoms. This preventive measure helps maintain the skin's integrity and reduces the risk of secondary infections.
Choice A rationale: Allowing the child to wear only 100% cotton clothing can help reduce skin irritation as cotton is a soft, breathable fabric. However, it is not as directly related to preventing the harm caused by scratching.
Choice B rationale: Applying baby lotion to the skin can help keep the skin moisturized, but it might not be sufficient for eczema management. A more intensive emollient or specific eczema treatment may be needed.
Choice C rationale: Bathing the child daily with bath oil can help moisturize the skin, but over-bathing can sometimes exacerbate eczema. It's important to use gentle, non-irritating bath products and to follow other guidelines, such as trimming nails.
Correct Answer is ["18"]
Explanation
Step 1 is to calculate the infusion rate. The prescription is for heparin 900 units/hr IV. The IV bag contains heparin 25,000 units in 500 mL of 0.45% normal saline.
So, the calculation would be (900 units ÷ 25,000 units) × 500 mL = 18 mL/hr.
