When initiating oxygen per mask to a client who is short of breath, the nurse hears a loud hissing sound after inserting the flowmeter into the wall outlet. Which should the nurse do next?
Assess the position of the mask on the client's face.
Release and reinsert the flowmeter in the wall outlet.
Attach the flowmeter to a humidification canister.
Adjust the flow rate to the prescribed liters per minute.
The Correct Answer is B
Choice A reason: Assessing the position of the mask on the client's face is not the priority action. The mask may be well-fitted, but the oxygen delivery may be compromised by the faulty connection of the flowmeter.
Choice B reason: Releasing and reinserting the flowmeter in the wall outlet is the best action as it may correct the problem of the loose or misaligned connection. The nurse should ensure that the flowmeter is securely attached and that the oxygen is flowing properly.
Choice C reason: Attaching the flowmeter to a humidification canister is not necessary for oxygen delivery per mask. Humidification is usually added for high-flow oxygen devices such as nasal cannula or face tent.
Choice D reason: Adjusting the flow rate to the prescribed liters per minute is not the appropriate action. The flow rate may be correct, but the oxygen delivery may be impaired by the hissing sound indicating a leak or obstruction.

Correct Answer is A
Explanation
Choice A reason: Positive external places are images of pleasant and relaxing environments that can distract the client from the pain and induce a sense of calmness and well-being. Examples of positive external places are a beach, a garden, or a mountain.
Choice B reason: Emotional reflection is a process of exploring and expressing one's feelings and emotions. It may be helpful for some clients to cope with stress and anxiety, but it is not the best focus for guided imagery for chronic pain. Emotional reflection may trigger negative emotions or memories that can worsen the pain perception.
Choice C reason: Motivational phrases are statements that encourage and inspire the client to achieve a goal or overcome a challenge. They may be useful for some clients to boost their self-confidence and self-efficacy, but they are not the best focus for guided imagery for chronic pain. Motivational phrases may not be effective in reducing the pain intensity or duration.
Choice D reason: Tranquil sounds are noises that create a soothing and peaceful atmosphere. They may be helpful for some clients to relax and fall asleep, but they are not the best focus for guided imagery for chronic pain. Tranquil sounds may not be enough to divert the client's attention from the pain or create a positive emotional state.

Correct Answer is C
Explanation
Choice A reason: Removing the nasal cannula is not appropriate as it would deprive the client of supplemental oxygen. The client's oxygen saturation is below the normal range of 95% to 100%, indicating hypoxemia.
Choice B reason:While increasing oxygen might seem appropriate, this should only be done after verifying the accuracy of the pulse oximeter reading and assessing the client’s overall condition. Automatically increasing oxygen without further assessment could delay addressing other underlying issues or lead to over-oxygenation in clients with certain conditions like COPD.
Choice C reason:The first step is to ensure the accuracy of the pulse oximeter reading by checking its placement and ruling out factors that can interfere with accurate readings, such as poor circulation, cold extremities, nail polish, or motion artifacts. This ensures that the subsequent intervention is based on reliable data.
Choice D reason: Switching to a non-rebreather mask is not necessary as it would deliver a high concentration of oxygen (up to 100%) that may be excessive for the client. A nasal cannula can deliver oxygen from 1 to 6 L/minute, depending on the client's needs.
