Dizziness is a symptom, not a NANDA-I diagnosis, so the nursing diagnosis you choose depends on what the dizziness is doing to the client. The most common choice is Risk for Adult Falls, because dizziness is a major fall risk factor. Others are Deficient Fluid Volume when dehydration causes lightheadedness on standing, Nausea when vertigo makes the client sick, and Fear or Impaired Physical Mobility when the client stops moving. Nursing care centers on finding the type and cause of the dizziness, checking orthostatic vital signs, keeping the client safe from falls, reviewing medicines, and escalating fast when dizziness comes with stroke or heart warning signs.
At a glance
- What it is
- A loose word clients use for four different feelings: spinning (vertigo), feeling faint (presyncope), feeling off balance (disequilibrium), and a vague woozy or “foggy” feeling. Ask the client to describe it without using the word “dizzy.”
- Who gets it
- Older adults, clients who are dehydrated or bleeding, those on blood pressure medicines, diuretics, sedatives, or many medicines at once, clients with heart rhythm problems, inner ear disorders, low blood glucose, anemia, or anxiety, and anyone getting up after bed rest.
- Key signs
- Lightheadedness or spinning, unsteady gait, reaching for furniture, nausea, pallor, sweating, nystagmus, a drop in blood pressure on standing, and a fast heart rate on standing.
- Nursing focus
- Describe the type, check orthostatic vital signs and glucose, review medicines, keep the client safe (call light, assisted transfers, slow position changes), replace fluids as ordered, ease nausea, and teach safe movement at home.
- Act now
- Call the provider or rapid response team for dizziness with new weakness, numbness, facial droop, slurred speech, double vision, or trouble walking; a sudden severe headache; chest pain or palpitations; fainting; signs of bleeding; or new sudden hearing loss. Note the time and stay with the client.
Pathophysiology
Balance depends on three inputs: the vestibular system of the inner ear, vision, and position sense from the joints and feet. The brainstem and cerebellum combine them, and the brain also needs steady blood flow, oxygen, and glucose. Dizziness appears when one of these inputs gives a wrong signal or when the brain is briefly underfed.
- Presyncope (feeling faint) — blood flow to the brain drops for a moment. Causes include orthostatic hypotension from dehydration, bleeding, diuretics, and blood pressure medicines; heart rhythm problems; a weak heart; and a vasovagal response.
- Vertigo (spinning) — the vestibular system sends a false signal of movement. Peripheral (inner ear) causes are common and include benign paroxysmal positional vertigo (BPPV), vestibular neuritis, labyrinthitis, and Ménière’s disease. Central causes in the brainstem or cerebellum, such as a stroke, are less common but dangerous.
- Disequilibrium (off balance) — the client feels unsteady on their feet rather than in the head. It is common with nerve damage in the feet, weak legs, poor vision, Parkinson disease, and many medicines together.
- Nonspecific lightheadedness — often linked to anxiety and fast breathing, low blood glucose, anemia, or medicine side effects.
When the brain gets mismatched signals from the ear and the eyes, the vomiting center is triggered, which is why vertigo so often brings nausea. In older adults, dizziness is usually caused by more than one thing at once, such as a diuretic plus poor fluid intake plus weak legs, so the nursing assessment looks for every contributing factor, not just one.
Telling the types apart
| Type | What the client says | Common causes | Nursing priority |
|---|---|---|---|
| Presyncope | “I feel like I’m going to pass out.” Worse on standing. | Orthostatic hypotension, dehydration, bleeding, arrhythmia, medicines | Orthostatic vital signs, heart rhythm, fluid status, medicine review |
| Vertigo | “The room is spinning.” Worse with head movement or rolling over. | BPPV, vestibular neuritis, Ménière’s disease, stroke (less common) | Neuro check to rule out stroke, nausea control, safe movement |
| Disequilibrium | “I feel unsteady on my feet.” | Nerve damage in the feet, weakness, poor vision, many medicines | Gait and fall risk, assistive device, PT referral |
| Lightheadedness | “I feel woozy” or “foggy.” | Anxiety, low glucose, anemia, medicine side effects | Glucose check, review labs and medicines, breathing coaching |
Nursing assessment
Subjective data
- What the dizziness feels like, in the client’s own words (spinning, faint, unsteady, woozy)
- When it started, how long each episode lasts, and whether it is constant or comes and goes
- Triggers: standing up, rolling over in bed, turning the head, looking up, after meals, with stress
- Associated symptoms: nausea, vomiting, ringing in the ears, hearing loss, ear fullness, headache, double vision, chest pain, palpitations, shortness of breath, black stools
- Recent falls or near falls, and fear of falling
- Fluid intake, vomiting, diarrhea, and urine output
- All medicines, including new or changed doses, over-the-counter sleep aids and antihistamines, and alcohol use
- History of diabetes, heart disease, stroke, ear disorders, migraine, and anxiety
Objective data
- Orthostatic blood pressure and heart rate (see below)
- Heart rate and rhythm; an ECG or telemetry if the provider orders it
- Point-of-care glucose, especially in clients with diabetes or poor intake
- Neuro check: level of consciousness, speech, facial symmetry, arm and leg strength, eye movements, and nystagmus
- Gait, balance, and how the client gets up from a chair; use of furniture or walls for support
- Fluid status: mucous membranes, skin turgor, intake and output, urine color, daily weight
- Pallor, sweating, and signs of bleeding
- Fall risk score using the tool your facility uses
- Lab results the provider orders, such as hemoglobin, electrolytes, BUN, and creatinine
Checking orthostatic vital signs
- Have the client lie down for about 5 minutes, then measure blood pressure and heart rate.
- Help the client stand (or sit at the edge of the bed if standing is unsafe), staying close with a gait belt.
- Measure again at 1 minute and at 3 minutes after standing, and ask about symptoms each time.
- Stop and return the client to bed if they become faint, pale, or sweaty.
Orthostatic hypotension is commonly defined as a systolic drop of 20 mmHg or more, or a diastolic drop of 10 mmHg or more, within 3 minutes of standing. A large rise in heart rate on standing points toward low fluid volume. Symptoms on standing matter even when the numbers do not meet the definition. Facility procedures differ slightly, so follow your policy and report the results to the provider.
Nursing diagnoses used with dizziness
- Risk for Adult Falls — the most common choice; dizziness, orthostatic hypotension, and medicines are risk factors
- Deficient Fluid Volume — dizziness on standing from fluid loss
- Nausea — from vertigo and motion
- Fear — fear of falling or of the next spinning attack
- Impaired Physical Mobility — the client limits movement because of unsteadiness
- Risk for Injury — broader injury risk, for example while driving or at work
- Self-Care Deficit (bathing, toileting) — when dizziness makes self-care unsafe without help
- Inadequate Health Knowledge — gaps in knowing about safe position changes, medicines, and warning signs
Worked care plans
Four plans in the same ADPIE shape. The scenario is a 76-year-old woman admitted after nearly falling on her way to the bathroom at night. She has had 3 days of vomiting and diarrhea from a stomach virus and has been drinking little. She takes lisinopril and hydrochlorothiazide for blood pressure. She says, “Every time I stand up, everything goes gray and I feel like I’m going to pass out.” Lying down, her blood pressure is 128/74 and heart rate 84. After 1 minute of standing it is 102/62 with a heart rate of 112, and she says she feels faint. Her mucous membranes are dry, her urine is dark and scant, and her BUN and creatinine are above her baseline. Her neuro check is normal, her ECG shows sinus rhythm, and her glucose is 112 mg/dL. She is still nauseated. The provider orders IV fluids, an antiemetic, labs, and holds her lisinopril and hydrochlorothiazide.
1. Risk for Adult Falls
RiskSubjective: “I nearly went down last night.” “I don’t want to bother anyone to help me up.”
Objective: Orthostatic drop in blood pressure with symptoms; age 76; takes a diuretic and an antihypertensive; urgency from diarrhea; unfamiliar room; high score on the facility fall risk tool.
Risk for Adult Falls related to orthostatic hypotension, dizziness, bowel and urinary urgency, and use of a diuretic and an antihypertensive; at-risk population: older adult with a recent near fall.
A risk diagnosis names the risk factors only. There are no signs and symptoms to list, because the fall has not happened.
- Client has no falls during the hospital stay
- Client calls for help before getting up every time
- Client shows how to change position slowly in stages
- Start fall precautions per facility policy: bed in low position, wheels locked, call light and personal items within reach, nonslip socks, clear path to the bathroom, and a night light
- Place a bedside commode and offer toileting on a schedule, including at night
- Use a bed or chair alarm if facility policy supports it
- Help her with every transfer and walk, using a gait belt, until orthostatic vital signs and symptoms improve
- Teach staged position changes: sit up, dangle the legs, pump the ankles, then stand slowly and wait before walking
- Recheck orthostatic vital signs as ordered and report results
- Tell her clearly that calling for help is expected, not a bother
She had no falls during the stay. She used the call light before each trip to the commode and on day 2 showed the staged rise from bed without prompting. Goal met; continue fall precautions until discharge.
2. Deficient Fluid Volume
Problem-focusedSubjective: “I haven’t been able to keep anything down.” “My mouth is so dry.”
Objective: Standing blood pressure 102/62 with heart rate 112, compared with 128/74 and 84 lying down; dry mucous membranes; dark, scant urine; BUN and creatinine above her baseline; 3 days of vomiting and diarrhea.
Deficient Fluid Volume related to insufficient fluid intake as evidenced by decreased blood pressure on standing, increased heart rate, dry mucous membranes, and decreased urine output; associated condition: active fluid loss from vomiting and diarrhea.
- Orthostatic vital signs return toward her baseline without symptoms
- Urine output returns to the range her provider wants, with lighter urine
- Client drinks fluids as tolerated once nausea eases
- Give IV fluids at the ordered type and rate, and watch for crackles, swelling, or shortness of breath, especially in an older client
- Keep accurate intake and output, including vomit and stools, and weigh daily on the same scale
- Hold the diuretic and antihypertensive as ordered, and check with the provider before giving any other medicine that lowers blood pressure
- Offer small, frequent sips of oral fluids or an oral rehydration drink as nausea allows
- Monitor labs the provider orders, such as electrolytes, BUN, and creatinine, and report abnormal results
- Recheck orthostatic vital signs as ordered
After 24 hours, lying blood pressure was 132/76 with heart rate 78, and after 3 minutes standing it was 124/72 with heart rate 88 and no dizziness. Urine was light yellow, and she was drinking well. Goal met. The provider will decide when to restart her blood pressure medicines.

3. Nausea
Problem-focusedSubjective: “My stomach turns every time I sit up.” “I can’t even think about food.”
Objective: Gagging when moved; refused breakfast; pale and sweaty during position changes; one episode of vomiting this morning.
Nausea related to gastrointestinal irritation and dizziness with movement as evidenced by reports of nausea, gagging, aversion to food, and increased sweating.
- Client rates nausea as low enough to drink fluids
- Client has no further vomiting
- Client tolerates small meals by day 2
- Ask her to rate her nausea on a 0–10 scale before and after interventions
- Give the ordered antiemetic, ideally before activities that trigger nausea, and watch for drowsiness, which raises fall risk
- Move her slowly and limit sudden head movement
- Keep the room cool, quiet, and free of strong smells; offer mouth care after vomiting
- Start with sips of clear fluids, then small, bland meals as tolerated
- Keep an emesis basin and call light within reach, with the head of the bed raised to lower the risk of aspiration
Her nausea dropped from 7 to 2 out of 10 after the antiemetic and slower position changes. She had no more vomiting and ate half of a bland lunch on day 2. Goal met.
4. Fear
Problem-focusedSubjective: “I’m scared to get out of bed. What if I fall and break my hip like my sister did?” “I live alone.”
Objective: Refuses to sit in the chair; grips the bed rail during repositioning; asks repeatedly whether she will be able to go home.
Fear related to the threat of falling and loss of independence as evidenced by reported fear, avoidance of movement, and repeated questions about going home.
- Client states she feels safer moving with help
- Client sits in the chair for meals with assistance
- Client names a plan for getting help at home if she feels dizzy
- Let her talk about her fear and acknowledge it; it is a reasonable fear after a near fall
- Explain the cause of her dizziness and that it is expected to improve as her fluids are replaced
- Start with small, successful steps, such as sitting at the edge of the bed with you beside her
- Request a physical therapy evaluation for gait, strength, and a walking aid if needed
- Involve family and the case manager in planning help at home, such as a personal alert device
- Avoid long bed rest, which weakens the legs and worsens dizziness on standing
By day 2 she sat in the chair for meals and walked in the hall with PT and a walker. She said, “I feel better now that I know why it happened,” and her daughter arranged to stay with her for the first week at home. Goal met.
Interventions and rationales
Client and family teaching
- Change position in stages: sit up, wait, dangle your legs, pump your ankles, then stand slowly and hold onto something steady before walking
- If you feel dizzy, sit or lie down right away, wherever you are, rather than trying to reach a chair across the room
- Drink fluids through the day unless your provider has limited them, and drink more when you are sick, sweating, or in the heat
- Keep an up-to-date list of all your medicines, and ask your provider or pharmacist whether any could be making you dizzy; do not stop a prescribed medicine on your own
- Make your home safer: night lights, clear paths, no loose rugs, grab bars in the bathroom, and the things you use most within easy reach
- Use the walking aid you were given, wear supportive shoes, and keep your eyeglasses clean and on
- Do not drive, climb ladders, or use dangerous equipment until your dizziness is controlled and your provider says it is safe
- If you have diabetes, check your blood glucose when you feel dizzy and treat a low reading the way your provider taught you
- Call 911 for dizziness with a drooping face, arm or leg weakness, slurred speech, trouble seeing, sudden severe headache, chest pain, or fainting

You’ve read the care plan. Now answer one.
A priority item in the NCLEX format. On Prep, every option gets a written rationale — including the three that are wrong.
The nurse is caring for four clients who report dizziness. Which client should the nurse see first?
Why C. Sudden dizziness with double vision and trouble sitting upright are signs of a possible stroke in the brainstem or cerebellum, which is time-critical. The nurse screens for stroke, notes the time last known well, and activates the stroke response per protocol. Option A is the typical, expected pattern of BPPV. Option B describes known symptoms of Ménière’s disease. Option D needs fall precautions and orthostatic vital signs, but the client is stable now. Prep also explains why each wrong option looks reasonable.

Frequently asked questions
What is the nursing diagnosis for dizziness?
Dizziness is a symptom, not a NANDA-I label. The most common nursing diagnosis is Risk for Adult Falls. Depending on the cause, Deficient Fluid Volume, Nausea, Fear, Impaired Physical Mobility, or Risk for Injury may also fit.
What is the difference between dizziness and vertigo?
Dizziness is a broad term. Vertigo is one type of dizziness: a false feeling that you or the room is spinning or moving, usually from an inner ear or brain problem. Feeling faint or lightheaded is a different type, usually from low blood flow to the brain.
What is the priority nursing intervention for a dizzy client?
Safety comes first: help the client sit or lie down and prevent a fall. Then assess for dangerous causes, including stroke signs, heart rhythm problems, low blood pressure, low blood glucose, and bleeding, and report them right away.
How do nurses check orthostatic vital signs?
Measure blood pressure and heart rate after the client has been lying down for about 5 minutes, then again at 1 and 3 minutes after standing, asking about symptoms each time. A systolic drop of 20 mmHg or more, or a diastolic drop of 10 mmHg or more, within 3 minutes is the common definition of orthostatic hypotension. Follow your facility’s procedure.
Is “Disturbed Sensory Perception” still used for vertigo?
No. That label was removed from NANDA-I. For a client with vertigo, choose diagnoses based on the effect, such as Risk for Adult Falls, Nausea, or Impaired Physical Mobility.
When is dizziness an emergency?
When it starts suddenly with stroke signs (face drooping, weakness, slurred speech, double vision, trouble walking), a severe headache, chest pain, palpitations, shortness of breath, fainting, or signs of bleeding. These need immediate escalation.
