📋 Scenario
A patient on oxygen says his mouth is dry all the time.
Subjective (S): "My mouth is so dry."
Objective (O): Dry cracked lips; thick saliva; mouth breathing; on oxygen; fluid sips limited.
Assessment tools for this scenario: CP-PAIN Pain & Comfort Score CP-FLUID Fluid Balance & Nutrition Score
Validated scales to consider: NRS 0–10, FLACC, PAINAD, MUST, fluid chart, glucose
**CarePath diagnosis:** Dry mouth or thirst related to fluid restrictions, as evidenced by dry sticky mouth and cracked lips.
**Interventions and rationale**
| Intervention | Rationale |
|---|---|
| Give frequent mouth care. | Regular mouth care moistens the mouth, removes thick saliva and reduces germs, which improves comfort and protects the teeth and gums. |
| Offer ice chips or sips if allowed. | Ice chips or sips give moisture in small amounts, easing thirst without going over the fluid limit set by the care team. |
| Use lip balm. | Lip balm seals in moisture and prevents cracks, which are painful and can let germs in. |
| Humidify oxygen. | Oxygen is dry and dries the nose and mouth, so humidifying it adds moisture to the air breathed in. |
| Encourage fluids as allowed. | Allowed fluids replace losses and ease thirst, so the patient drinks as much as permitted without breaking the restriction. |
**Expected outcomes**
- Within 24 hours: mouth moist and lips not cracked.
- Patient reports thirst relief.
- Mouth care done every 2 hours.
**Linking the data to the diagnosis**
The patient on oxygen says his mouth is so dry. The nurse saw dry cracked lips, thick saliva, mouth breathing and limited fluid sips. These signs show the mouth is dry and sticky now, so this is an actual diagnosis, with the fluid limit and oxygen as likely causes. Because fluids are restricted, the plan must ease thirst within the limit, using mouth care and moisture rather than large drinks. It aims within 24 hours for a moist mouth and uncracked lips, the patient reporting thirst relief, and mouth care every 2 hours.
