A nurse is reinforcing teaching with the partner of a client who is immobile. Which of the following instructions should the nurse give the partner about turning the client in bed?

The correct answer is **d. Attach a humidifier to the base of the flow meter**.

Choice A rationale:

Keeping the side holes of the mask closed would restrict airflow and prevent the client from receiving the prescribed oxygen concentration. This action would be unsafe and should not be taken.

Choice B rationale:

Ensuring the reservoir bag is inflated on expiration is not necessary for a simple face mask. The reservoir bag is typically used with other oxygen delivery devices, such as a non-rebreather mask, to provide a higher concentration of oxygen. This action is not appropriate for the given scenario.

Choice C rationale:

Applying petroleum jelly to the client's nostrils is not a recommended action. Petroleum jelly can potentially cause irritation and dryness, which could lead to discomfort for the client. This action is not necessary for the safe administration of oxygen.

Choice D rationale:

Attaching a humidifier to the base of the flow meter is the appropriate action to ensure client safety. Humidifying the oxygen can help prevent drying of the client's airway and make the oxygen more comfortable to breathe. This is a recommended step when administering high-flow oxygen via a simple face mask.

The correct answer is choice A: "Perform muscle relaxation before bedtime."

Choice A rationale:

Suggesting to the client to "Perform muscle relaxation before bedtime" is a helpful recommendation. Muscle relaxation techniques, such as progressive muscle relaxation or deep breathing exercises, can help calm the body and mind, making it easier to fall asleep.

Choice B rationale:

Advising the client to "Exercise vigorously 1 hour prior to going to bed" is not recommended. Vigorous exercise close to bedtime can actually stimulate the body and make it harder to fall asleep. Gentle, non-strenuous activities are more suitable before bedtime.

Choice C rationale:

Recommending the client to "Drink a cup of hot chocolate at bedtime" is not ideal. Hot chocolate contains caffeine, which is a stimulant that can interfere with sleep. It's better to avoid caffeine-containing beverages close to bedtime.

Choice D rationale:

Suggesting the client to "Change the time you go to sleep each day" disrupts the body's internal clock and sleep-wake cycle. Maintaining a consistent sleep schedule, even on weekends, helps regulate the body's natural sleep patterns.
