A head-to-toe assessment is a systematic physical examination that moves through every body system in a logical sequence, from the general appearance down to the feet. Whether you’re a nursing student preparing for clinicals or a new nurse building confidence, the key to a smooth assessment is following the same order every time so it becomes second nature. Here’s how to work through each step.
Gather Your Supplies First
Before you touch the patient, collect everything you’ll need: a stethoscope, penlight, watch with a second hand, gloves, hand sanitizer, and a wound measurement tool if applicable. Having supplies ready prevents you from leaving the room mid-assessment, which breaks your flow and can make the patient uneasy. Perform hand hygiene, introduce yourself, verify the patient’s identity, and explain what you’ll be doing.
Start With the General Survey
The assessment begins the moment you walk into the room. Before any hands-on examination, you’re observing the whole picture: Is the patient alert? Are they sitting upright or slumped? Do they make eye contact, or are they withdrawn? This initial impression is called the general survey, and it captures things a stethoscope can’t.
Look at posture first. Normal posture means parallel alignment from the shoulders to the hips, whether sitting or standing. Note if the patient appears hunched, rigid, or contracted. Next, assess affect and mood. Facial expressions, eye contact, and verbal responses all give you clues. A “flat affect,” meaning very few visible emotional expressions, can point toward depression or neurological changes.
Then observe hygiene, grooming, and dress. Look at the cleanliness of the hair, face, and nails. Note any odors, which can indicate poor hygiene or certain disease states. Check whether clothing is clean and appropriate for the season. If it isn’t, that may reflect changes in cognitive ability, emotional state, or the capacity to handle daily activities. These observations aren’t small details. They often flag problems that a focused physical exam would miss entirely.
Head, Eyes, Ears, Nose, and Throat (HEENT)
Begin by inspecting the head for skin color and symmetry of facial movements. Look for any drooping. If you notice asymmetry, ask the patient to smile, frown, and raise their eyebrows, then watch whether both sides of the face move equally. Unequal movement can signal a stroke or nerve damage and needs immediate follow-up.
For the eyes, use your penlight to check that both pupils are equal in size, round, and reactive to light. Each pupil should constrict when you shine the light into it and return to its normal size when you remove it. Check that the patient can track your finger smoothly through all directions of gaze.
Inspect the ears for drainage or visible abnormalities. Move to the nose and check for patency (whether air flows freely through each nostril) and any nasal drainage. For the throat, ask the patient to open their mouth and say “Ah.” Use a tongue blade and good lighting. Inspect the oral mucosa for color and any sores. Gums should be pink, with no swelling, bleeding, or ulceration. Note any missing, loose, or discolored teeth. The tongue should sit at the midline with no coatings or sores, and the uvula should rise symmetrically when the patient vocalizes. Also note whether the patient can swallow their own secretions comfortably.
Finally, inspect the neck. The trachea should be midline. Look for any visible enlargement of lymph nodes or the thyroid gland.
Respiratory Assessment
Count the respiratory rate using your watch with a second hand. Normal adult rate is 12 to 20 breaths per minute. Observe the depth and rhythm of breathing and note whether the patient uses accessory muscles in the neck or abdomen to breathe, which suggests respiratory distress.
Then auscultate the lungs with the diaphragm (flat side) of your stethoscope. Start at the top of the chest (the apices) and move downward until you no longer hear breath sounds. Then repeat on the back, again starting at the top and working down. The critical rule: always compare symmetrical points on each side before moving lower. Listen for at least one full breath cycle at each spot. You’re listening for clear, equal breath sounds on both sides. Crackles, wheezes, or diminished sounds on one side are abnormal findings worth reporting.
Cardiovascular Assessment
Take the patient’s blood pressure and heart rate. Then auscultate the heart at five specific landmarks, working in order:
- Aortic area: right side of the breastbone, between the second and third ribs
- Pulmonic area: left side of the breastbone, same level (between the second and third ribs)
- Erb’s point: left side of the breastbone, between the third and fourth ribs
- Tricuspid area: lower left side of the breastbone, between the fourth and fifth ribs
- Mitral area: left side of the chest at the fifth rib space, in line with the middle of the collarbone
At each site, listen with both the bell (cupped side, for low-pitched sounds) and the diaphragm (flat side, for high-pitched sounds). You’re identifying the normal “lub-dub” of heart valves closing. Any extra sounds, swooshing (murmurs), or irregular rhythms are abnormal findings.
Abdominal Assessment
The abdomen follows a different order than every other body system: you inspect, then auscultate, then percuss, then palpate. This sequence matters. Palpation can stimulate bowel activity, which would falsely increase bowel sounds if you hadn’t listened first. Starting with inspection and auscultation also puts the patient at ease before you press on their belly.
Visually inspect the abdomen for shape, symmetry, skin changes, or visible pulsations. Then place your stethoscope lightly on each of the four quadrants and listen for bowel sounds. Normal bowel sounds are irregular gurgling or clicking noises. After auscultation, you can percuss (tap) across the four quadrants to identify areas of unusual dullness or gas. Finally, palpate lightly first, then more deeply, watching the patient’s face for signs of pain. Always palpate a reported painful area last.
Peripheral Vascular Assessment
Check circulation by palpating pulses at standard sites: radial (wrist), brachial (inner elbow), femoral (groin), popliteal (behind the knee), posterior tibial (inner ankle), and dorsalis pedis (top of the foot). Compare both sides. Pulse intensity is graded on a 0 to 4 scale:
- 0: No pulse felt
- 1+: Barely detectable
- 2+: Slightly diminished
- 3+: Normal, easily felt
- 4+: Bounding, stronger than expected
Also assess skin temperature, color, and capillary refill in the extremities. Press a fingernail bed briefly; color should return within 2 seconds. Check for edema by pressing the skin over the shin or ankle for a few seconds and observing whether a pit (indentation) remains. Pitting edema is graded from 1 to 4: Grade 1 leaves a 2 mm pit that rebounds immediately. Grade 2 leaves a 3 to 4 mm pit that rebounds within 15 seconds. Grade 3 produces a 5 to 6 mm pit taking up to 60 seconds to rebound. Grade 4 creates an 8 mm pit that can take two to three minutes to fill back in.
Neurological Assessment
A basic neurological check covers level of consciousness, orientation, cranial nerve function, sensation, and reflexes. The Glasgow Coma Scale (GCS) is the standard tool for scoring consciousness. It measures three responses, each scored from 1 (no response) upward:
- Eye opening: 1 (none) to 4 (spontaneous)
- Verbal response: 1 (none) to 5 (oriented and conversational)
- Motor response: 1 (none) to 6 (obeys commands normally)
A perfect score is 15, meaning the patient opens their eyes spontaneously, speaks clearly and knows who and where they are, and moves purposefully on command. A score of 8 or below generally indicates a severe impairment.
Beyond the GCS, check orientation by asking the patient to state their name, the date, and where they are. Test sensation by lightly touching the arms and legs with your fingers and asking the patient to confirm they feel it. Assess coordination by asking the patient to touch their nose and then your finger, alternating back and forth.
Musculoskeletal Assessment
Inspect the joints for swelling, redness, or deformity. Ask the patient to move each major joint through its full range of motion: shoulders, elbows, wrists, hips, knees, and ankles. Note any pain, stiffness, or limited movement.
Test muscle strength bilaterally using the 0 to 5 scale. Have the patient push or pull against your resistance:
- 0: No muscle activation at all
- 1: A slight twitch, but the limb can’t move through its range
- 2: Can move the limb fully only if gravity is eliminated (you support its weight)
- 3: Can move the limb fully against gravity but not against added resistance
- 4: Can resist some force but not full resistance
- 5: Normal, full strength against your resistance
Always compare one side to the other. A difference between left and right is often more telling than the absolute number.
Skin Assessment
You’ll be evaluating the skin throughout the entire exam, but take a deliberate look at overall skin color, moisture, temperature, and texture. Check for rashes, bruises, wounds, or pressure injuries, especially over bony prominences like the sacrum, heels, and elbows in patients with limited mobility. Note the size and characteristics of any wounds. If the patient has an IV site or surgical dressing, inspect those areas for redness, swelling, or drainage.
Putting It All Together
The total time for a head-to-toe assessment varies depending on the patient’s condition and how many findings require deeper investigation. With practice, a routine assessment on a stable patient flows quickly. The most important principle is consistency: follow the same sequence every time so you never accidentally skip a system. Many nurses use a mental or printed checklist until the pattern becomes automatic.
Document your findings promptly using whatever charting system your facility uses. Record both normal and abnormal findings for every system you assessed. For abnormal findings, note exactly what you observed, where, and any relevant measurements. Clear documentation protects the patient by giving the next provider a reliable baseline for comparison.
