Health Assessment: The General Survey and Subjective Data

Introduction to Health Assessments

Designed for students studying rn nursing fundamentals and other healthcare professionals, this article covers the core steps of nursing fundamentals and clinical evaluation: learning how to perform general survey observations and progressing into subjective data collection. When performing general survey evaluations, the provider does a rapid, initial visual and auditory assessment of a patient’s overall health status; while it helps identify acute distress, it is not a diagnostic tool and merely guides subsequent examination steps.

During a health assessment, providers collect both subjective and objective data. Subjective data includes symptoms and feelings reported directly by the patient (e.g., documenting “I feel a sharp pain in my chest when I breathe”), whereas objective data consists of measurable, observable signs (like blood pressure or heart rate). For a system-by-system breakdown of measurable findings, review the objective patient assessment. Typical sources of assessment data include interviewing the patient or family, performing a physical examination, and reviewing a laboratory diagnostic test or other diagnostic test results.

The General Survey: Make a Judgment Upon Entering the Patient’s Room

The general survey is a snapshot judgment the provider makes about their patient as they first enter the patient’s room. Rather than definitively diagnosing a condition, this rapid observation helps determine the patient’s level of acuity and whether they are in immediate distress. These initial clues prompt further, focused follow-up assessments rather than making a final diagnosis. When the provider walks into the room, they should mentally categorize their observations.

What are they seeing?

• How many intravenous (IV) pumps are in the room? Is the patient on oxygen, and if so, how much?
• What is the patient’s skin color? Is the color appropriate, or is it pale or blue?
• Are they smiling as the provider enters the room?
• Take note of their posture, movement quality, balance, and bilateral symmetry.
• Are they sitting up in bed or sitting in a chair? While a patient sitting up in a chair is often doing better than someone lying flat in bed, this is not a universal rule; observe their overall energy and posture for true context.
• Does the patient use any assistive devices such as a cane or walker?

A general survey of the patient can offer clues to how a patient is doing.

What are they hearing, both verbally and nonverbally?

• Does the patient appear to be in any kind of distress? For example, if the patient is sitting in a tripod position and breathing heavily, they are in respiratory distress.
• Are they responsive and oriented? Quickly assess orientation by casually asking questions to confirm they know their name (person), where they are (place), and the date or time of day (time).
• Evaluate communication: is their speech clear, and do they have the ability to follow basic instructions?
• Is there a language barrier requiring an interpreter?
• Is there an emotional component to their words, or any nonverbal communication, such as tone or body language indicating severe anxiety, pain, or depression?

Is there anything unusual we need to further assess?

• What does the IV site look like, and what IV medications are they receiving? A patient on several IV medications could be sicker than a patient who is not receiving any.
• Look at the patient’s general appearance. Is the patient well-nourished? Does the patient look appropriately their age?

Quick General Survey Checklist (30 to 60 seconds)

To turn these observations into a repeatable workflow, use this mental checklist as you enter:

• ABCs: Briefly observe Airway, Breathing, and Circulation.
• Neurological: Check responsiveness, orientation, and mood.
• Mobility/Posture: Note symmetry, distress positioning, and assistive devices.
• Environment: Scan for monitors (such as a pulse oximeter), IVs, and oxygen delivery.

What is the Objective Assessment?

Before diving deep into subjective data, it is crucial to understand the other half of the evaluation process. The video below provides an excellent overview of the objective assessment, demonstrating how providers gather measurable data, such as a specific vital sign and physical exam findings, to complete the clinical picture.

What is the Subjective Assessment?

The subjective assessment involves gathering vital, self-reported health history directly from the patient. While patients may occasionally become talkative about unrelated past medical events, providers must efficiently redirect the conversation to perform a focused assessment based on the current presenting problem.

The standard workflow dictates starting with the chief complaint, utilizing focused questions based on that complaint, and only then expanding to broader medical history. Crucially, cues gathered from your general survey should dictate this focus; for example, if you observed the patient in obvious respiratory distress or confusion upon entering, your subjective questioning should immediately target those systems, especially when considering conditions like the types of pneumonia.

When charting, subjective data should always be documented exactly as patient-reported information. Whenever appropriate, use quotation marks to capture the patient’s own words (e.g., Patient states, “My chest feels like there is a heavy weight on it”).

Ask about the Chief Complaint

For example, a patient named Mike presents with a chief complaint of abdominal pain. That is where the provider will focus the subjective assessment, asking questions to find out the history of present illness.

To gather medical information, ask questions. Keep the questions focused.

Since the patient’s chief complaint is pain, the provider would use the PQRST method. The same structured questioning process is commonly used within the chest pain algorithm when evaluating possible acute coronary syndrome symptoms. When doing this, avoid medical jargon; reframe each letter into patient-friendly wording:

• P – Provoke: “What makes the pain better or worse, like eating or moving?”
• Q – Quality: “Can you describe what the pain feels like? Is it sharp, dull, or stabbing?”
• R – Radiates: “Does the pain move or shoot anywhere else in your body?”
• S – Severity: “On a scale from 1 to 10, with 10 being the worst, how bad is the pain?”
• T – Time: “Exactly when did this pain start happening?”

Caution: While the patient’s description of symptom location might suggest certain conditions, it is not definitive. Keep the chief complaint section strictly focused on structured questioning to gather facts rather than attempting to hunt for diagnosis hints.

The following sections outline the rest of the subjective data needed for clinical paperwork.

Ask about Medications

Always ask about medications. If the patient takes any medications at home, the provider will have to evaluate whether the medications are appropriate to continue at the hospital.

Ask about Allergies

Ask about allergies. Does the patient have any allergies to food or medications? Have they ever eaten a food or taken a medication and broken out in hives? The patient’s responses need to be documented. The provider also needs to document if the patient has no known allergies.

Ask about Family History

Next is the family history. The most important people to collect information on are the mother, father, and any siblings.

For family history, the medical team typically wants to know about any history of heart disease, hypertension, diabetes, and cancer. The provider may ask something like, “Does your mother have a history of heart disease?” “What about your father?” The provider will also document whether family members are living or not.

For the family history, ask about the patient’s parents and any siblings.

Understanding how to systematically evaluate a patient is a vital skill. To see how these subjective data gathering techniques and objective assessments fit into high-stakes, rapid-response environments, watch the video below detailing the ACLS systematic approach.

Complete a Review of Systems

The Review of Systems (ROS) is a structured inventory of the body’s organ systems designed to identify associated symptoms and pertinent negatives relevant to the chief complaint. While it is important to keep the patient focused on the main reason for their visit, this organized review ensures no critical clues are missed.

Returning to our patient Mike, who presented with abdominal pain, the provider would start first with the gastrointestinal (GI) system. If the provider runs out of time or gets pulled out of the room, gathering that specific system data is the priority. The provider might ask Mike:

• Have you had any other symptoms along with the abdominal pain?
• Any changes in bowel patterns?
• Nausea or vomiting?
• Any bloody stools, diarrhea, or constipation?
• Changes in appetite?
• Where are you hurting? Is the pain on the side, middle, upper, or lower part of the abdomen?

While asking about pain location is highly important, remember that location alone is not definitive. Instead of instantly assuming a specific cause, focus your ROS on gathering structured symptom data and surgical history to inform follow-up clinical testing rather than attempting to make a bedside diagnosis.

Once the GI system is covered, the provider will start at the head and work down through the other systems.

A review of the bodily systems helps collect information about the patient’s organ systems. The provider may not have time to cover every organ system.

Starting from the top with the head, eyes, ears, and nose, the provider will ask about the neurology system:

• Any problems with headaches?
• What about any numbness? Tingling?
• Any history of seizures?
• Any eye pain or vision problems?
• Any ringing in the ears?

If the provider asks, “Do you have tinnitus?”, the patient may be confused. Ask them instead if they have ringing in their ears. Providers need to talk in words the patient understands.

Next is the cardiovascular system. Questions for this body system may include:

• Any chest pain?
• Any palpitations where the heart feels like it is beating out of the chest or that it feels like it is beating irregularly?
• Any trouble with your blood pressure?
• Any medication for a heart condition?

Next is the respiratory system. Questions about this body system may include:

• Any shortness of breath currently or in the past?
• Any cough?

If the patient has a cough, the provider should follow up and ask if it is productive or nonproductive and about the appearance of the sputum.

The GI system is next. For the example patient above, this system has already been addressed. However, another important thing to ask, particularly with older patients, is if they have any trouble swallowing. That is important to know if they need to be on aspiration precautions.

Next is the genitourinary system. Questions for this system include:

• Any changes in urination patterns?
• Any difficulty urinating?
• Any pain with urination?
• Any history of urinary tract infections?

Finally, the provider should ask about hematology and endocrinology. For endocrinology, the only question may be about diabetes unless the provider needs to know more. Questions to ask about these systems include:

• Do you find that you bruise easily?
• Do you bleed easily?
• Do you have any history of diabetes?
• Any family history of diabetes?

In women, the provider may want to ask about the thyroid during the review of the endocrine system. Sometimes, women may come in with hypothyroidism.

There are several questions that the provider can ask during the review of systems. Remember that the review needs to keep the patient-focused on the main reason for the visit.

Additional Information

Along with the chief complaint, history of present illness, and review of systems, there are some additional items to collect for your clinical paperwork and ongoing safety planning. One critical thing to ask is the patient’s code status. Is the patient full code or do not resuscitate (DNR)?

Additionally, you must assess and document fall precautions. You can directly connect this safety planning to the mobility issues, posture, or assistive devices you initially observed during your general survey upon entering the room.

Summary

Conducting a thorough health assessment is a foundational skill in clinical practice. By starting with a sharp, observant general survey, providers can rapidly gauge a patient’s acuity and readiness for the interview. Following this with a structured subjective assessment, utilizing tools like the PQRST method and a focused Review of Systems, ensures that all critical patient-reported data, from chief complaints to family histories, is accurately captured and documented to shape their ongoing care.
