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 C

Explanation

A: Keeping a fluorescent ceiling light on at night can be too bright and disrupt sleep. A nightlight is a better option for safety without disturbing sleep.

B: Keeping the walker at the end of the bed is not ideal. The walker should be within easy reach to prevent falls when getting out of bed.

C: Placing a bath seat in the shower is a good safety measure. It provides stability and reduces the risk of slipping and falling while bathing.

D: Placing an area rug at the entry of the bathroom can be a tripping hazard. It is better to use non-slip mats that are securely placed.

A. Intact skin with localized erythema. B. Full-thickness skin loss with visible adipose tissue. C. Partial-thickness skin loss with red tissue in wound bed. D. Full-thickness skin loss with visible bone.

Correct Answer is C

Explanation

A: Intact skin with localized erythema describes a stage 1 pressure injury, where the skin is not broken but shows signs of redness and irritation. This stage does not involve any loss of skin layers.

B: Full-thickness skin loss with visible adipose tissue is characteristic of a stage 3 pressure injury. At this stage, the injury extends through the full thickness of the skin and exposes fat tissue, but not muscle, bone, or tendon.

C: Partial-thickness skin loss with red tissue in the wound bed is indicative of a stage 2 pressure injury. This stage involves damage to the epidermis and dermis, resulting in a shallow, open wound with a red or pink wound bed. It may also present as an intact or ruptured blister.

D: Full-thickness skin loss with visible bone describes a stage 4 pressure injury. This stage involves extensive destruction, with tissue loss extending to muscle, bone, or supporting structures.
