Understanding Altered Mental Status
Definition of Altered Mental Status
Altered mental status (AMS) refers to a broad spectrum of cognitive alterations that affect a person's level of consciousness, awareness, perception, or responsiveness. It is characterized by any deviation from normal mental function, which may include confusion, disorientation, decreased alertness, agitation, hallucinations, or coma.
Significance of Nursing Diagnosis in AMS
Prompt identification and accurate nursing diagnosis of AMS are essential because they guide appropriate interventions, facilitate communication among healthcare team members, and help monitor the patient's progress.

Common Causes of Altered Mental Status
Understanding the etiology of AMS helps nurses develop targeted care plans. Causes can be classified into several categories:
Medical Causes
- Infections: Meningitis, encephalitis, sepsis
- Metabolic disturbances: Hypoglycemia, hyponatremia, hypercalcemia
- Neurological conditions: Stroke, traumatic brain injury, seizures
- Toxicity: Drug overdose, alcohol poisoning, poisoning from chemicals
- Organ failure: Liver failure (hepatic encephalopathy), renal failure
Psychological and Environmental Causes
- Severe stress, psychiatric illnesses, sensory deprivation, or environmental factors such as hypoxia or hypothermia.

Assessment and Data Collection for Altered Mental Status
A thorough assessment is the cornerstone of identifying and diagnosing AMS.
Initial Evaluation
- Airway, Breathing, Circulation (ABCs): Ensure airway patency, adequate ventilation, and stable circulation.
- Level of Consciousness (LOC): Use tools like the Glasgow Coma Scale (GCS) to quantify LOC.
- Vital Signs: Monitor for fever, hypoxia, hypotension, or other abnormalities.
- Neurological Examination: Assess pupils, motor responses, reflexes, and cranial nerve function.
- History Taking: Obtain detailed history from patient or witnesses about recent events, medication use, substance intake, or trauma.
Additional Diagnostic Tests
- Laboratory tests (blood glucose, electrolytes, renal and liver function tests)
- Imaging (CT scan, MRI)
- Lumbar puncture if infection or neurological pathology is suspected
- Toxicology screening

Nursing Diagnoses Related to Altered Mental Status
Based on assessment findings, nurses formulate nursing diagnoses. Here are some common nursing diagnoses associated with AMS:
Primary Nursing Diagnoses
1. Risk for Injury related to altered mental status
2. Impaired Cognition related to neurological impairment or metabolic imbalance
3. Ineffective Airway Clearance related to decreased consciousness
4. Impaired Urinary Elimination related to altered mental status and immobility
5. Risk for Falls related to confusion, dizziness, or weakness
6. Anxiety related to disorientation and unfamiliar environment
Additional Nursing Diagnoses
- Impaired Communication related to decreased LOC
- Impaired Skin Integrity related to immobility and incontinence
- Imbalanced Nutrition: Less than Body Requirements related to decreased consciousness and inability to feed self

Goals and Expected Outcomes in Nursing Care
Nursing care aims to stabilize the patient's condition, prevent complications, and promote recovery. Typical goals include:
- Maintaining a patent airway
- Preventing injury and falls
- Achieving a stable neurological status
- Promoting adequate hydration and nutrition
- Ensuring safety and comfort
- Facilitating family support and education
Expected outcomes should be specific, measurable, achievable, relevant, and time-bound (SMART). Examples include:
- Patient will maintain a patent airway with oxygen saturation above 92% within 24 hours.
- Patient will demonstrate orientation to person, place, and time within 48 hours.
- Patient will remain free from falls or injury during hospitalization.
- Family will verbalize understanding of patient's condition and care plan before discharge.
