Nausea, characterized by an unsettling sensation in the throat, upper abdomen, or stomach, often precedes vomiting but may occur independently. It’s a common symptom across various medical conditions, ranging from gastrointestinal issues to medication side effects and pregnancy. Understanding the nuances of nausea is crucial for healthcare professionals to provide effective patient care.
Nausea isn’t a disease itself but rather a symptom signaling an underlying condition. It can arise from a multitude of factors, including:
- Gastrointestinal Disorders: Infections, overeating, acid reflux, and bowel obstructions can disrupt normal digestive processes, leading to nausea.
- Psychological Factors: Anxiety and stress can manifest physically as nausea.
- Medications: Many drugs list nausea as a potential side effect.
- Pregnancy: Hormonal changes during pregnancy are a well-known cause of morning sickness and nausea.
- Motion Sickness: Disorientation from movement can trigger nausea.
- Central Nervous System Issues: Conditions affecting the brain and nervous system can induce nausea.
- Metabolic Imbalances: Disorders disrupting the body’s metabolism can present with nausea.
- Cardiovascular Problems: Heart conditions can sometimes manifest as nausea.
Subjectivity is a key aspect of nausea. Patients often describe it alongside anorexia or a decreased appetite. Prolonged nausea and vomiting cycles can lead to serious complications like dehydration, electrolyte imbalances, extracellular fluid depletion, and circulatory problems.
Effective nursing care for nausea focuses on identifying and addressing the root cause, managing potential complications, and providing symptomatic relief. A thorough assessment is paramount to pinpoint contributing factors. In situations like chemotherapy, where nausea is anticipated, proactive premedication is essential. Educating patients about non-pharmacological strategies to prevent and manage nausea is also a vital nursing intervention.
Nursing care plans are instrumental in structuring and prioritizing care for patients experiencing nausea and vomiting. These plans guide assessments and interventions, ensuring both immediate and long-term care goals are met. Let’s explore specific nursing diagnoses and tailored care plan examples for nausea and vomiting.
Addressing Dysfunctional Gastrointestinal Motility in Nausea
Disruptions in gastrointestinal motility, whether increased or decreased, can manifest as nausea, vomiting, bloating, abdominal discomfort, and altered bowel function.
Nursing Diagnosis: Dysfunctional Gastrointestinal Motility
Related Factors:
- Underlying disease processes
- Anxiety and stress
- Dietary changes and malnutrition
- Unpleasant sensory stimuli
- Enteral feedings
- Unsanitary food handling
Evidenced By:
- Food aversion and altered taste
- Increased salivation and swallowing
- Gagging sensation
- Abdominal pain and cramping
- Abdominal distension and altered bowel sounds
- Regurgitation and sour taste
- Nausea and vomiting
Expected Outcomes:
- Patient will exhibit normal bowel sounds and patterns.
- Patient will tolerate regular meals without nausea, vomiting, or abdominal discomfort.
Nursing Assessment and Interventions:
1. Investigate Causative Factors:
Rationale: Identifying the underlying cause of altered gastrointestinal motility, such as gastrointestinal disorders, food sensitivities, medications, or medical conditions, is crucial for targeted treatment.
Action: Conduct a comprehensive patient history, including medical history, medication review, dietary habits, and recent illnesses.
2. Evaluate Food Intake and Triggers:
