A nurse is teaching a newly licensed nurse about a nonrebreather oxygen mask. Which of the following instructions should the nurse include?
Use a nonrebreather mask to deliver low-flow oxygen
A nonrebreather mask should fit snugly over a client's face.
The reservoir bag on a nonrebreather mask should collapse with
A nonrebreather mask dries a client's mucous membranes
The Correct Answer is B
A. A nonrebreather mask is used to deliver high-flow oxygen, not low-flow. It provides the highest concentration of oxygen compared to other types of masks, which is crucial for patients with severe hypoxemia. The high-flow oxygen helps in achieving a higher concentration of oxygen in the blood.
B. It is essential that a nonrebreather mask fits snugly over the client's face to ensure that the patient receives the maximum amount of oxygen and to prevent room air from mixing with the oxygen being delivered. A proper seal is necessary to achieve the desired level of oxygenation and to avoid oxygen leakage.
C. The reservoir bag on a nonrebreather mask should not collapse with each breath. Ideally, the bag should remain partially inflated even during inspiration. If the bag collapses completely, it indicates that the patient is not receiving enough oxygen, and the mask may not be functioning correctly.
D. A nonrebreather mask itself does not cause drying of the mucous membranes. However, high-flow oxygen can sometimes lead to dryness of the mucous membranes if not managed properly. Humidification may be required to prevent dryness, but this is not a direct effect of the mask itself.

Correct Answer is D
Explanation
A. Obesity does not selectively affect only certain types of surgical procedures; rather, it generally increases the risk of complications across a wide range of surgical interventions. This includes both elective and emergency surgeries.
B. Obesity significantly impacts surgical risk. It is associated with a higher likelihood of complications such as wound infections, delayed wound healing, respiratory problems, and cardiovascular issues. The presence of excess body fat affects multiple physiological systems and can complicate both the surgical procedure and recovery.
C. Obesity does not decrease the risk of surgical complications; rather, it increases it. The excess body fat associated with obesity can lead to problems such as impaired wound healing, increased risk of infection, cardiovascular strain, and respiratory issues, which all contribute to a higher risk of complications during and after surgery.
D. This statement accurately reflects the relationship between obesity and surgical risk. Obesity is associated with an increased risk of a variety of surgical complications.
Correct Answer is C
Explanation
A. Lisinopril is an ACE inhibitor used to treat hypertension and heart failure. It can affect blood pressure regulation and might impact intraoperative and postoperative blood pressure control, but it is not generally associated with increased surgical bleeding risk.
B. Acetaminophen is a pain reliever and antipyretic used for mild to moderate pain and fever. It does not have a significant impact on bleeding risk or interfere with clotting mechanisms. It is generally considered safe for use around the time of surgery.
C. Aspirin is an antiplatelet medication that inhibits platelet aggregation and can increase the risk of bleeding. It affects blood clotting and can lead to excessive bleeding during and after surgery. It is often recommended to stop aspirin use several days before surgery to reduce this risk, unless specifically directed otherwise by the healthcare provider.
D. Metoprolol is a beta-blocker used to manage hypertension and heart conditions. It is generally not associated with increased bleeding risk.
