A nurse receives an order from the provider for a client requiring the highest oxygen concentration with a one-way valve. What type of mask should the nurse apply to the client?

Simple face mask

Venturi mask

Non-rebreather mask

Partial rebreather mask

Answer and Explanation

The Correct Answer is C

A: A simple face mask provides a moderate concentration of oxygen but does not have a one-way valve to deliver the highest concentration of oxygen.

B: A Venturi mask delivers a precise concentration of oxygen but is not designed to provide the highest concentration of oxygen with a one-way valve.

C: A non-rebreather mask is the correct choice. It has a one-way valve that prevents exhaled air from re-entering the bag, allowing the delivery of the highest concentration of oxygen to the client.

D: A partial rebreather mask provides a high concentration of oxygen but does not have a one-way valve, making it less effective than a non-rebreather mask for delivering the highest oxygen concentration.

Correct Answer is D

Explanation

A: Hypotension is not an early sign of hypoxemia. It can occur in severe cases but is not typically an initial indicator.

B: Nausea is not a common sign of hypoxemia. It may occur due to other factors but is not directly related to low oxygen levels.

C: Dysphagia, or difficulty swallowing, is not a sign of hypoxemia. It is related to swallowing disorders rather than oxygen levels.

D: Confusion is an early sign of hypoxemia. Low oxygen levels can affect brain function, leading to confusion and other cognitive changes.

A. Check the client’s skin every 8 hours for signs of breakdown. B. Clean the client’s skin and perineum with hot water after each episode of incontinence. C. Apply a moisture barrier ointment to the client’s skin. D. Request a prescription for the insertion of an indwelling urinary catheter.

Correct Answer is C

Explanation

A: Checking the client’s skin every 8 hours is not frequent enough to prevent skin breakdown in a client with urinary incontinence. More frequent checks are necessary to identify and address any issues promptly.

B: Cleaning the client’s skin and perineum with hot water can cause skin irritation and dryness. It is better to use lukewarm water and gentle cleansers to maintain skin integrity.

C: Applying a moisture barrier ointment to the client’s skin is an effective way to prevent skin breakdown. The ointment creates a protective barrier that helps keep moisture away from the skin, reducing the risk of irritation and breakdown.

D: Requesting a prescription for the insertion of an indwelling urinary catheter is not the best first-line intervention for preventing skin breakdown. Catheters carry a risk of infection and should be used only when absolutely necessary.
