NCLEX-PN® ExaminationBasic Care and ComfortHard
A client is experiencing severe nausea and vomiting post-chemotherapy. The LPN is preparing to provide oral care. Which solution is most appropriate for rinsing the client's mouth?
- ALemon-glycerin swabs
- BAlcohol-based mouthwash
- CHydrogen peroxide solution
- DNormal saline solution
Show answer & explanationAnswer & explanation
Correct answer: D. Normal saline solution
Normal saline solution is the most appropriate choice for rinsing the mouth of a client with severe nausea and vomiting. It is isotonic, non-irritating, and helps to cleanse and soothe the oral mucosa without causing further drying or irritation, which can be exacerbated by vomiting.
Why the other options are wrong
- A. Lemon-glycerin swabs are often discouraged because lemon can be acidic and erode tooth enamel, and glycerin can dry mucous membranes over time.
- B. Alcohol-based mouthwashes are drying and irritating to already compromised oral mucosa, and can worsen nausea.
- C. Hydrogen peroxide, especially in high concentrations, can be irritating to mucous membranes and may cause further damage or discomfort.
Oral Care for Nausea/Vomiting
Oral care for clients experiencing nausea and vomiting requires gentle, non-irritating solutions to cleanse the mouth, remove emesis residue, and prevent further discomfort or mucosal damage.
- Avoid drying or irritating agents.
- Saline is a safe and effective rinse.
- Frequent care prevents breakdown and infection.
