A nurse is preparing to insert an indwelling urinary catheter for a client. Which of the following actions should the nurse plan to take?
Test the balloon on the indwelling urinary catheter before insertion.
Use one cotton swab to clean the client's urinary meatus.
Don sterile gloves before inserting the indwelling urinary catheter.
Apply an oil-based lubricant to the indwelling urinary catheter.
The Correct Answer is C
Choice A reason: Testing the balloon is important, but it is not the action to take immediately before insertion.
Choice B reason: While cleaning the urinary meatus is necessary, using one cotton swab is not sufficient for proper aseptic technique.
Choice C reason: Donning sterile gloves is essential to maintain an aseptic technique during catheter insertion to prevent infection.
Choice D reason: An oil-based lubricant should not be used as it can increase the risk of infection and is not compatible with the catheter material; a water-soluble lubricant is recommended.

Correct Answer is C
Explanation
Choice A reason: The reservoir bag on a nonrebreather mask should not collapse with exhalation. It is designed to maintain a continuous flow of oxygen and reserve a volume of oxygen for the patient to inhale with each breath.
Choice B reason: While high-flow oxygen can dry a patient's mucous membranes, a nonrebreather mask typically has a high oxygen flow rate, and humidification can be used to prevent drying.
Choice C reason: A nonrebreather mask must fit snugly over the patient's face to ensure that the highest concentration of oxygen is delivered and that there is minimal dilution with room air.
Choice D reason: A nonrebreather mask is used to deliver high-flow oxygen, not low-flow. It is designed to provide a high concentration of oxygen, typically around 60% to 90% FiO2.
Correct Answer is A
Explanation
Choice A reason: An IV infusion of dextrose 10% in water can cause hyperglycemia, which is an elevated blood sugar
level.
Choice B reason: Hypovolemia, or decreased blood volume, is not a typical adverse effect of dextrose infusion.
Choice C reason: Hypercalcemia, or high calcium levels in the blood, is not associated with dextrose infusion.
Choice D reason: While dextrose infusion can affect electrolyte balance, hypokalemia, or low potassium levels, is not
the primary concern with dextrose infusion.
