1. Introduction to Nausea and Vomiting
Nausea and vomiting are common symptoms experienced across all age groups that significantly impact quality of life. As a community health nurse, understanding these symptoms is crucial for effective patient care. Nausea is an unpleasant sensation of the imminent need to vomit, often accompanied by autonomic symptoms such as pallor, sweating, and tachycardia. Vomiting is the forceful expulsion of gastric contents through the mouth.
Key Definitions
- Nausea: A subjective sensation of the need to vomit
- Vomiting: The forceful expulsion of gastric contents
- Retching: The rhythmic, spasmodic contractions of the respiratory muscles without the expulsion of gastric contents
- Regurgitation: The passive reflux of undigested food without the forceful contraction of abdominal muscles
In community health settings, nurses are often the first healthcare professionals to conduct nausea assessment and manage these symptoms. This guide provides comprehensive information for community health nurses to effectively assess, diagnose, manage, and refer patients experiencing nausea and vomiting.
2. Epidemiology and Impact in Community Settings
Nausea and vomiting affect approximately 25-30% of the general population annually, with varying prevalence based on age, gender, and underlying conditions:
| Population | Prevalence | Common Causes |
|---|---|---|
| General Adult Population | 25-30% annually | Gastroenteritis, medication side effects, motion sickness |
| Pregnant Women | 70-80% (first trimester) | Hormonal changes, hyperemesis gravidarum |
| Pediatric Population | 3-7 episodes per year | Infections, food poisoning, motion sickness |
| Elderly Population | 15-20% annually | Medication side effects, gastrointestinal disorders, metabolic disorders |
| Cancer Patients | 40-70% during treatment | Chemotherapy, radiation therapy, advanced disease |
Community impact includes increased healthcare utilization, decreased work productivity, and significant effects on quality of life. Proper nausea assessment and management can significantly reduce this burden and improve patient outcomes.
3. Standing Orders: Definition and Uses
Standing orders are written documents containing rules, policies, procedures, and protocols for the care of a patient population with identified health conditions. They authorize nurses and other healthcare professionals to carry out specific interventions without a direct physician order.
Definition of Standing Orders
Standing orders are pre-approved, written protocols that authorize healthcare professionals to perform specific interventions under certain circumstances without requiring a physician’s direct order at the time of care.
Uses of Standing Orders in Nausea and Vomiting Management
- Facilitate timely nausea assessment and early intervention
- Standardize care based on evidence-based practices
- Improve efficiency in managing common symptoms
- Empower nurses to initiate appropriate treatments
- Reduce delays in symptom management
- Ensure consistent care across different healthcare providers
Components of Standing Orders for Nausea and Vomiting

4. Pathophysiology and Clinical Manifestations
Understanding the pathophysiology of nausea and vomiting is essential for effective nausea assessment and management. The vomiting center in the medulla oblongata coordinates the complex process of vomiting through various inputs:
Pathophysiology of Nausea and Vomiting
Clinical Manifestations
Common clinical manifestations that may be identified during nausea assessment include:
| System | Manifestations |
|---|---|
| Gastrointestinal | Nausea, vomiting, retching, anorexia, abdominal discomfort |
| Autonomic Nervous System | Pallor, diaphoresis, increased salivation, tachycardia |
| Fluid and Electrolyte | Dehydration, electrolyte imbalances (hypokalemia, metabolic alkalosis) |
| Neurological | Dizziness, headache, fatigue, weakness |
| Psychological | Anxiety, distress, anticipatory nausea |
Vomitus Characteristics and Clinical Significance
| Characteristic | Possible Cause | Clinical Significance |
|---|---|---|
| Coffee-ground appearance | Partially digested blood | Upper GI bleeding |
| Bright red blood | Active bleeding | Immediate referral required |
| Bilious (green) | Bile reflux | Possible intestinal obstruction |
| Feculent | Intestinal obstruction | Surgical emergency |
| Projectile | Increased intracranial pressure | Neurological emergency |
5. Screening and Assessment Techniques
Effective screening and nausea assessment are crucial first steps in the management of nausea and vomiting. Community health nurses should employ a systematic approach to evaluation.
5.1 Screening Tools
Several validated tools can assist in the standardized nausea assessment:
| Assessment Tool | Description | Application |
|---|---|---|
| Visual Analog Scale (VAS) | 10cm line where patients mark severity from “no nausea” to “worst possible nausea” | Quick assessment for adults and older children |
| Numerical Rating Scale (NRS) | 0-10 scale where 0 is “no nausea” and 10 is “worst possible nausea” | Simple quantification for adults |
| PUQE Scale (Pregnancy-Unique Quantification of Emesis) | 3-item questionnaire assessing nausea duration, vomiting frequency, and retching frequency | Specifically for pregnancy-related nausea and vomiting |
| BARF Scale (Baxter Animated Retching Faces) | Pictorial scale with 6 faces ranging from happy to extremely nauseated | Pediatric assessment (age 4-18) |
| Rhodes Index of Nausea, Vomiting, and Retching (INVR) | 8-item scale measuring frequency, duration, and distress | Comprehensive assessment for research and clinical practice |
5.2 History Taking
A comprehensive history is essential for thorough nausea assessment. Use the PQRST method adapted for nausea and vomiting:
PQRST for Nausea and Vomiting Assessment
- Provoke: What triggers or worsens the nausea? What makes it better?
- Quality: How would you describe the sensation? (e.g., waves, constant, burning)
- Region: Is there any associated abdominal pain or discomfort? Where?
- Severity: On a scale of 0-10, how severe is the nausea?
- Timing: When did it start? How long does it last? Frequency of vomiting?
Additional important history to collect:
- Characteristics of vomitus (amount, color, content, presence of blood)
- Associated symptoms (fever, diarrhea, constipation, headache, dizziness)
- Recent illnesses or exposures (food poisoning, viral gastroenteritis)
- Medication review (new medications, changes in dosage)
- Medical history (gastrointestinal disorders, pregnancy, metabolic disorders)
- Psychosocial factors (stress, anxiety, anticipatory nausea)
- Diet history and food intake patterns
- Fluid intake and output (signs of dehydration)
5.3 Physical Assessment
Physical examination complements the history in nausea assessment:
| Assessment Component | Technique | Findings to Document |
|---|---|---|
| Vital Signs | Measure temperature, pulse, respiration, blood pressure | Tachycardia, hypotension (dehydration), fever (infection) |
| Hydration Status | Assess skin turgor, mucous membranes, capillary refill | Poor skin turgor, dry mucous membranes, delayed capillary refill |
| Abdominal Examination | Inspect, auscultate, percuss, palpate | Distention, tenderness, masses, altered bowel sounds |
| Neurological Assessment | Mental status, cranial nerves, balance | Altered mental status, nystagmus, balance issues |
| Weight | Compare to baseline | Weight loss, indicating severity and chronicity |
ABCDES of Dehydration Assessment
- Appearance – Lethargy, listlessness
- Blood pressure – Hypotension, orthostatic changes
- Capillary refill – Delayed (>2 seconds)
- Dryness of mucous membranes – Dry lips, tongue
- Elasticity of skin – Poor skin turgor
- Sunken eyes/fontanelle (in infants)
6. Diagnosis and Identification
