A nurse is reinforcing teaching with a newly licensed nurse about a nonrebreather mask. Which of the following instructions should the nurse include?
The reservoir bag on a nonrebreather mask should collapse with exhalation.
A nonrebreather mask dries a patient's mucous membranes.
A nonrebreather mask should fit snugly over a patient's face.
Use a nonrebreather mask to deliver low-flow oxygen
The Correct Answer is C
Choice A reason: The reservoir bag on a nonrebreather mask should not collapse with exhalation. It is designed to maintain a continuous flow of oxygen and reserve a volume of oxygen for the patient to inhale with each breath.
Choice B reason: While high-flow oxygen can dry a patient's mucous membranes, a nonrebreather mask typically has a high oxygen flow rate, and humidification can be used to prevent drying.
Choice C reason: A nonrebreather mask must fit snugly over the patient's face to ensure that the highest concentration of oxygen is delivered and that there is minimal dilution with room air.
Choice D reason: A nonrebreather mask is used to deliver high-flow oxygen, not low-flow. It is designed to provide a high concentration of oxygen, typically around 60% to 90% FiO2.

Correct Answer is C
Explanation
The correct answer is c. "You will have a stoma placed in your right lower abdomen."
Choice A reason: The stoma should appear red and moist, similar to the inside of the mouth, not purple.
Choice B reason: The stoma does not have nerve endings, so it should not be painful.
Choice C reason: An ileostomy is typically placed in the right lower abdomen.
Choice D reason: Stool passing through an ileostomy is usually liquid to pasty, not solid.
Correct Answer is D
Explanation
Choice A reason: The small intestine is not the starting point of the digestive process. It is where most of the digestion and absorption of nutrients occurs after the food has been processed in the stomach.
Choice B reason: The rectum is the final section of the large intestine, where feces are stored before being expelled. It is not involved in the initial stages of digestion.
Choice C reason: The stomach is involved in the early stages of digestion, particularly in the breakdown of proteins, but it is not the starting point. Food enters the stomach after being ingested through the mouth.
Choice D reason: The mouth is the correct starting location for the digestive process. Here, ingestion takes place, and mechanical digestion begins with chewing, while chemical digestion starts with enzymes in the saliva breaking down carbohydrates.
