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?

  1. ALemon-glycerin swabs
  2. BAlcohol-based mouthwash
  3. CHydrogen peroxide solution
  4. DNormal saline solution
Show answer & 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.
