Pain, Nutrition, Mobility, and Functional Status
Key Takeaways
- Pain assessment includes function, safety, etiology, and response to treatment, not only a numeric score.
- Nutrition and hydration affect wound healing, immune function, medication safety, and discharge readiness.
- Early mobility prevents complications but must be balanced with physiologic stability and fall risk.
- Functional assessment guides care coordination, patient teaching, and safe transition planning.
Pain, Nutrition, Mobility, and Functional Status
Integrating comfort and recovery
Adult med-surg nursing requires more than treating the admitting diagnosis. Pain, nutrition, mobility, sleep, cognition, elimination, and functional status influence recovery, complications, length of stay, and discharge safety. CMSRN scenarios often place these needs next to acute physiologic risks. The nurse must address comfort and function while still prioritizing instability. A patient with severe new chest pain is assessed before routine ambulation. A stable postoperative patient with uncontrolled incisional pain may need pain management before coughing, deep breathing, or mobilizing effectively.
| Care need | CMSRN cue | Nursing response |
|---|---|---|
| Pain | Pain limits coughing, turning, sleep, or mobility | Reassess cause, treat as ordered, monitor sedation and function |
| Nutrition | Poor intake, weight loss, dysphagia, wound, or infection | Screen risk, protect swallowing, coordinate dietitian support |
| Mobility | Weakness, orthostasis, oxygen need, lines, or falls history | Match assistance level to risk and stop activity for instability |
| Discharge function | Unsafe transfers, medication access, or caregiver gap | Escalate to case management, therapy, social work, or pharmacy |
Pain assessment and management
Pain assessment includes location, intensity, quality, onset, duration, aggravating and relieving factors, associated symptoms, functional impact, patient goal, prior response, and safety concerns. A numeric score alone is incomplete. Pain that is expected after surgery differs from pain suggesting complication. New severe abdominal pain with rigid abdomen, chest pain with diaphoresis, calf pain with swelling, or limb pain with neurovascular changes requires escalation.
Use multimodal pain management when ordered and appropriate: nonopioid analgesics, opioids, neuropathic agents, heat or cold when safe, positioning, splinting, relaxation, mobility planning, and patient education. Monitor for adverse effects. Opioids can cause respiratory depression, sedation, nausea, constipation, urinary retention, delirium, falls, and ileus. Nonsteroidal anti-inflammatory drugs can increase bleeding and kidney risk. Acetaminophen requires attention to total daily dose and liver disease. Evaluation includes pain score, function, sedation, respiratory status, and side effects.
Nutrition and hydration
Nutrition supports wound healing, immune function, muscle strength, medication tolerance, and glycemic stability. Risk factors for malnutrition include poor intake, weight loss, dysphagia, nausea, vomiting, diarrhea, depression, food insecurity, alcohol use disorder, chronic illness, pressure injury, burns, cancer, and advanced age. The nurse assesses intake, weight trends, albumin or prealbumin only in context, chewing and swallowing, dentition, diet order, cultural preferences, nausea, bowel function, glucose, and ability to feed self.
Hydration affects perfusion, kidney function, delirium risk, constipation, medication clearance, and orthostasis. Monitor intake and output, urine characteristics, daily weights when indicated, mucous membranes, edema, lung sounds, blood pressure, heart rate, labs, and fluid restrictions. Both dehydration and fluid overload are dangerous. A heart failure patient who is thirsty may still need fluid restriction education, while a patient with vomiting and tachycardia may need prompt fluid assessment.
Common nursing actions include aspiration precautions, swallow screening when indicated, upright positioning for meals, oral care, antiemetic timing, dietitian referral, glucose coordination with meals, supplements, assistance with feeding, and communication about NPO status. For enteral feeding, verify tube placement per policy, maintain head-of-bed elevation when appropriate, monitor tolerance, flush as ordered, and protect skin around tubes.
Mobility and deconditioning
Hospitalization rapidly reduces strength and endurance. Early mobility helps prevent atelectasis, pneumonia, venous thromboembolism, constipation, pressure injury, delirium, and functional decline. Mobility plans must be individualized. Assess baseline function, current strength, gait, balance, pain, lines and drains, oxygen need, orthostatic symptoms, weight-bearing status, cognition, and assistive devices. Coordinate with physical therapy and occupational therapy, but do not wait for therapy for all safe routine mobility within nursing scope and policy.
Before ambulation, ask whether the patient is stable enough. Red flags include chest pain, severe shortness of breath, syncope, uncontrolled arrhythmia, marked hypotension, new neurologic deficit, excessive sedation, unsafe oxygenation, or provider restrictions. During mobility, use gait belts, nonskid footwear, appropriate staff assistance, oxygen extension management, and clear pathways. Stop activity for dizziness, chest pain, significant dyspnea, pallor, diaphoresis, or instability.
Functional status and discharge readiness
Functional assessment includes activities of daily living, instrumental activities, cognition, communication, continence, mobility, stairs, transportation, medication management, caregiver support, equipment, home environment, and financial barriers. A patient may be medically improved but unsafe for discharge if unable to obtain medications, manage wound care, access food, or transfer safely.
The RN coordinates with case management, social work, therapy, dietitian, pharmacist, wound care, respiratory therapy, and family or caregivers. Discharge teaching should be based on the patient's actual function and resources. A patient with limited hand dexterity may need a different insulin plan. A patient who lives alone and now requires a walker may need home health or rehabilitation placement. The CMSRN priority is realistic recovery: control pain enough for function, support nutrition, mobilize safely, and coordinate services that preserve safety after discharge.
A postoperative patient reports pain 8/10 and refuses to cough or ambulate because it hurts. Vital signs are stable and sedation is minimal. What is the best nursing action?
