A nurse is verifying informed consent for a client who is preoperative for a vaginal hysterectomy. Which of the following statements should the nurse identify as an indication that the client has given informed consent?

Delirium is a state of acute confusion and cognitive impairment that can cause disorientation and difficulty with time perception. Reminding the client of the day and time frequently helps provide orientation and reduce confusion. It can help ground the client in reality and improve their understanding of their current circumstances.

Avoiding discussing the client's fears can hinder their ability to express and address their concerns. It is important to provide a safe and supportive environment where the client can communicate their fears and feelings.

Offering the client several choices at mealtimes might be overwhelming and confusing for someone experiencing delirium. It is generally better to provide structure and simplicity in their meal options, reducing decision-making demands.

Alternating daily caregivers can disrupt continuity of care and increase the client's confusion. Consistency in the caregiving team can help establish a therapeutic relationship and familiarity, which can aid in managing delirium.

Explanation:

A nasal cannula is a device used to deliver supplemental oxygen to a client. It consists of two prongs that are inserted into the client's nostrils and connected to an oxygen source. The nasal cannula is commonly used for low-flow oxygen delivery at a rate of 1 to 2 liters per minute (L/min).

The other options mentioned are not necessary supplies for the client upon discharge:

B- Petroleum jelly is not directly related to oxygen therapy and is not a required supply for the client. It is a common topical ointment used for various purposes such as moisturizing the skin or protecting the lips, but it is not specifically needed for oxygen administration.

C- An oxygen mask is an alternative device for oxygen delivery but is not typically used at a flow rate of 1 to 2 L/min. Oxygen masks are usually employed for higher flow rates or in specific clinical situations that require a different oxygen delivery method.

D- A reservoir bag is a component of some oxygen delivery systems, such as a non-rebreather mask or a bag-valve-mask device. However, at a flow rate of 1 to 2 L/min, a reservoir bag is not typically used. It is more commonly utilized in situations where higher oxygen concentrations or higher flow rates are required.
