- Recall how the nurse will analyze data collected during the assessment
The information nurses gather about a patient’s health status is referred to as data. This information guides clinical decision-making and is essential in developing a personalized approach to care. Data collected during nursing assessments can be categorized into two types: objective and subjective (Lukey, 2023).
- Objective data are quantifiable and measurable aspects of a patient’s condition, such as vital signs, laboratory test results, and physical examination findings. These observable facts provide concrete evidence about the patient’s health.
- Subjective data consist of information provided directly by the patient or their caretakers, including their personal experiences, feelings, and perceptions of their health and symptoms. These data offer invaluable insights into the patient’s personal view of their health status and contribute to a holistic understanding of their needs.
Both types of data are indispensable in nursing assessments, complementing each other to create a full picture of a patient’s health.
This module explores the various data sources, discusses how nurses set priorities during the assessment process, and explains how nurses analyze the data they collect. Mastering these skills is integral to becoming a proficient and compassionate nursing professional.
Sources of Data
Nurses gather assessment data from a variety of sources, including the patients themselves and their family members or other caretakers. Information that comes directly from the patient is primary data, while secondary data comes from another source, such as a patient’s family member or medical record. Nurses also utilize their clinical skills and observations. Each data source provides unique insights, contributing to a comprehensive understanding of the patient’s health status.
The Patient
The patient is often the most important source of data in nursing assessments. Through direct communication with patients, nurses gather subjective data by asking open-ended questions, actively listening to their concerns, and exploring their perspectives on their health condition.
Subjective data gathered from the patient include their personal experiences, symptoms, feelings, beliefs, past medical history, medication history, and perceptions of their health. For example, a patient’s description of their pain—its location, intensity, and character—provides indispensable information that cannot be obtained through objective means alone. Patients can also offer key information about their lifestyle, such as dietary habits, exercise routines, and substance use, which are critical to understanding their overall health and well-being.
In addition to verbal communication, nonverbal cues from the patient, such as facial expressions, body language, and overall demeanor, offer valuable data. For instance, a patient’s posture and facial expressions can indicate pain or discomfort, even if they have not verbally expressed it. Effective communication skills, including active listening and empathetic engagement, are essential for nurses to interpret and utilize the data provided by the patient accurately.
The Family
Family members and significant others can also be key sources of data on a patient, especially in situations where the patient is unable to communicate effectively. Such may be the case for many pediatric, geriatric, or critically ill patients. Family members can provide historical information, corroborate patient reports, and offer insights into the patient’s normal behavior and daily functioning. For example, when assessing a patient with Alzheimer disease, family members can provide crucial information about the patient’s baseline cognitive function and recent changes in behavior or memory.
Family-provided data also extend to understanding the patient’s home environment and social support system, which are significant in planning postdischarge care. In pediatric care, the observations of parents and guardians when discussing a child’s symptoms, eating habits, and developmental milestones are invaluable in forming a complete assessment. It is also important for nurses to consider cultural and familial dynamics, as these influences determine the information provided by family members and the patient’s health practices and beliefs.
Cultural Context
Cultural Diversity and the Collection of Data
Understanding and respecting cultural diversity is essential in nursing assessments. Nurses often encounter patients from various cultural backgrounds, and recognizing how cultural factors influence health beliefs and practices is crucial for collecting accurate data. Here are some examples illustrating the importance of cultural awareness (U.S. Department of Health and Human Services, 2004):
- Communication styles: In some cultures, direct eye contact might be considered disrespectful, while in others, it is a sign of honesty and engagement. For instance, patients from certain Asian cultures may avoid direct eye contact with healthcare providers as a sign of respect, which should not be misinterpreted as disinterest or noncompliance.
- Pain expression: Cultural norms can influence how patients express pain. Some cultures encourage vocal expression of pain, while others may value stoicism. Nurses must realize that a patient who does not outwardly seem to be in pain might nevertheless be hurting.
- Family involvement: In many cultures, family plays a central role in healthcare decisions. In Hispanic and South Asian cultures, for example, family members, including extended family, often participate actively in care discussions and decision-making. Understanding these dynamics is important for communicating effectively and obtaining accurate health histories.
- Health beliefs and practices: Traditional health practices and beliefs can significantly influence a patient’s approach to illness and treatment. Many people that immigrate to the United States may use traditional healing practices alongside or in place of conventional medicine. Being open to these practices and respectfully discussing them can enhance trust and rapport.
- Dietary considerations: Dietary habits rooted in cultural practices can impact health and treatment plans. For example, certain religious practices, like fasting during Ramadan for Muslims or dietary restrictions in Hinduism, can affect medication schedules and nutritional needs.
By incorporating cultural awareness into the data collection process, nurses can ensure they are gathering complete and accurate information while also respecting each patient’s cultural background. This approach contributes to more holistic and patient-centered assessments, a crucial component of quality health care.
Nursing Skills
Nursing skills play a fundamental role in the collection of assessment data. These skills encompass a range of techniques and methods that nurses use to gather information about a patient’s health status. From observational skills to specific physical examination techniques, each skill contributes uniquely to the overall assessment. Proficiency in these skills enables nurses to collect both subjective and objective data effectively, forming the basis for accurate diagnoses and care planning (American Nurses Association, n.d.).

An overview of nursing skills for data collection is provided in this video.
Observational Skills
Observational skills in nursing involve the use of all senses to gather data about a patient. This includes noticing changes in skin color, body posture, facial expressions, and behaviors that might indicate pain or discomfort. For example, observing a patient’s gait can reveal a lot about their physical condition. A shuffling gait might indicate fear of falling, possibly due to balance issues or muscle weakness. A patient with a limp may be experiencing pain in the hip, knee, or foot, or they could have a muscular or skeletal abnormality. Alternatively, an unsteady or irregular gait might suggest neurological issues, such as those seen in patients with stroke history or Parkinson disease. By noting these specifics, a nurse can tailor the assessment and care plan to address mobility concerns.
Observational skills also extend to monitoring changes over time, such as tracking the progression of a wound’s healing or changes in a patient’s response to treatment. These skills are critical for identifying subtle changes that might not be explicitly communicated by the patient. Consider a patient who has reported feeling fine for several days but appears to wince when moving in bed one morning. This apparent contradiction between the patient’s words and behavior, caught through keen observation, can lead the nurse to uncover an issue that might otherwise have been overlooked.
Communication Skills
Effective communication skills are vital in nursing assessments to elicit subjective data from the patient. These skills include active listening, open-ended questioning, and empathetic responses that encourage patients to share concerns and symptoms. For instance, asking a patient to describe their pain in their own words and following up with open-ended questions can provide valuable information about the location, quality, and severity of the pain. A patient might initially complain of pain in their chest, but a skilled nurse can guide them to provide a more detailed description, such as “a squeezing sensation that radiates to my left arm.” A more specific description can be crucial for accurate diagnosis and timely intervention.
Communication skills also involve educating and informing patients about their condition and the assessment process, which can alleviate anxiety and build trust. Consider a patient who is hesitant to discuss their mental health and initially downplays their anxiety levels. Through empathetic and nonjudgmental communication, a nurse can create a safe space for the patient to open up about ongoing stressors. With this knowledge, specific strategies for alleviating stress can be incorporated into the patient’s care plan.
Inspection
A fundamental nursing skill known as inspection is when the nurse visually examines the patient’s body for normal and abnormal findings (Burke, 2023). It is often the first step in the physical examination process and can provide immediate clues about the patient’s health status. During inspection, nurses observe the patient’s overall appearance, noting factors such as skin color, posture, hygiene, and level of consciousness. Skin inspection allows nurses to assess for abnormalities such as pallor (pale color), cyanosis (blue color), jaundice (yellow color), rashes, bruises, lesions, or signs of inflammation, which may indicate underlying health conditions or injuries. For example, a nurse might inspect a patient’s skin for rashes, lesions, or signs of infection or a patient’s throat for redness or swelling. Posture and body alignment provide insights into musculoskeletal function and potential mobility limitations, while personal hygiene reflects the patient’s self-care abilities and overall health practices. For example, a patient with COPD may present with barrel chest and use of accessory muscles to breathe.
Inspection also extends to the patient’s behavior and affect, including facial expressions, gestures, speech patterns, and interactions with others. Observing for signs of distress, agitation, lethargy, or confusion helps nurses evaluate the patient’s cognitive and emotional status, detect changes in mental functioning, and assess their ability to communicate effectively. For example, a nurse caring for an older patient may assess cognitive function before and after a procedure to watch for any concerning changes from baseline.
Additionally, nurses may observe for nonverbal cues of pain or discomfort, such as grimacing, guarding, or restlessness, which inform pain assessment and management strategies. A common example would be observing a postoperative patient who has not yet fully recovered from anesthesia and sedation for nonverbal signs of discomfort.
Palpation
The technique of using one’s hands to feel the body for abnormalities during a physical examination is called palpation (Figure 12.2) (Burke, 2023). It assesses the texture, temperature, moisture, and size of organs and tissues. For example, during an abdominal assessment, the nurse may feel a pulsating mass in the midabdominal area, raising suspicion of an abdominal aortic aneurysm. Such a finding would warrant urgent medical evaluation.
Palpation can be light to assess surface characteristics or deep to assess organs or other structures within the body. This skill is crucial for obtaining information that cannot be gained through inspection alone.
Percussion
Tapping on the body to assess underlying structures is known in the healthcare field as percussion (Burke, 2023). The sound produced can indicate the presence of fluid, air, or solid tissue and is useful in assessing the size and density of organs. Percussion is commonly performed in respiratory and abdominal assessments. For instance, in respiratory assessments, percussion can help detect areas of lung consolidation or fluid accumulation; dull sounds over the lung fields, instead of the expected resonance (echoing sound), might indicate pneumonia. When percussing the abdomen, a shift in sound from the expected tympany (hollow sound) to dullness can confirm the presence of ascitic fluid, guiding further diagnostic testing and management. This technique requires skill to elicit and interpret the sounds correctly.

Auscultation
Listening to the sounds produced within the body, typically using a stethoscope, is called auscultation (Figure 12.3) (Burke, 2023). This technique is essential for assessing the function of the heart, lungs, and abdomen. For instance, when auscultating a patient’s heart, a nurse listens for abnormalities such as murmurs, which could indicate valvular heart disease. On the other hand, a high-pitched, whooshing sound heard at the heart’s apex could signify mitral regurgitation. Identifying specific sounds such as these is crucial for early intervention and referral to cardiology.
Auscultation of the lungs involves listening to breath sounds, including inspiratory and expiratory sounds, and any adventitious (unusual) sounds, such as crackles, wheezes, or rhonchi. These lung sounds provide information about the patency of the airways, ventilation-perfusion ratios, and the presence of conditions such as pneumonia, bronchitis, or pulmonary edema. For example, a patient with heart failure may present with crackles in the lung bases, indicative of fluid accumulation. Recognizing these abnormal breath sounds can prompt immediate interventions such as diuretic therapy to manage heart failure more effectively.
In addition to cardiac and respiratory auscultation, nurses may also perform auscultation of the gastrointestinal system to assess bowel sounds. Normal bowel sounds indicate the presence of peristalsis (digestive movement) and normal gastrointestinal motility, while changes in bowel sounds may signify conditions such as bowel obstruction (intestinal blockage), ileus (intestinal paralysis), or intestinal inflammation. Auscultating the abdomen allows nurses to monitor gastrointestinal function, assess for signs of bowel obstruction or impaction, and evaluate the effectiveness of interventions such as bowel rest or nasogastric tube decompression.
Establishing Priorities during Assessment
When assessing a patient to collect data, prioritization is usually necessary. Nurses often face complex situations and multiple health issues that need attention. They must quickly identify the most critical needs to address to ensure patient safety and well-being. This approach is particularly vital in emergency settings or with patients who have multiple chronic conditions of varying immediacy and severity. Prioritizing ensures that the most urgent conditions are treated promptly while still allowing other important health needs to be addressed in a systematic manner. Even for routine assessments, it is important to prioritize, as not every piece of data is relevant to a patient’s care.
ABCs
The ABC framework is a fundamental approach nurses use to establish priorities during an assessment, especially in emergency and acute care settings. This system uses the letters A (airway), B (breathing), and C (circulation) to remind providers to assess these components of health (Marymount University, 2022):
- Airway: An obstructed airway can rapidly lead to respiratory arrest. Therefore, the priority is to ensure the patient’s airway is open and clear. For example, in cases of trauma, swelling or foreign objects can obstruct the airway, necessitating quick intervention.
- Breathing: Once the airway is secured, the nurse assesses the patient’s breathing. This includes checking the rate, depth, and effort of breaths and observing for signs of respiratory distress. For instance, assessing for wheezing and use of accessory muscles is critical to managing the breathing of a patient with asthma.
- Circulation: The third priority is circulation. The nurse should assess the patient’s heart rate, blood pressure, and perfusion. Any signs of circulatory compromise, such as weak pulse, hypotension, or cyanosis, require immediate attention. For example, in a cardiac arrest scenario, restoring circulation through CPR is a priority.
Maslow’s Hierarchy
Another framework used by nurses to establish priorities, particularly for patients in less acute settings, is Maslow’s hierarchy of needs. Based on the work of the American psychologist Abraham Maslow, the hierarchy uses a triangle to organize human needs from the most basic (at the bottom) to the most complex (at the top) (Figure 12.4) (McLeod, 2018). Before humans can focus on meeting any particular need, they must have met the needs lower in the hierarchy (Marymount University, 2022).
- The hierarchy begins with physiological needs, which include basic requirements such as air, food, water, and shelter. In nursing, this means ensuring that a patient’s basic health needs, such as nutrition, hydration, and pain management, are met. For instance, a diabetic patient’s need for blood sugar regulation is a primary physiological concern.
- Safety and security needs come next, encompassing both a patient’s physical safety and psychological security. In a healthcare setting, this might involve reducing the risk of falls in older adult patients or reassuring anxious patients about their care and treatment.
- The hierarchy also includes psychological and self-fulfillment needs, such as love and belongingness, self-esteem, and self-actualization, which are more relevant in long-term care and holistic patient well-being. For example, addressing a patient’s social interactions and self-esteem issues is essential in mental healthcare and rehabilitation settings.
Nursing Process
The nursing process is a systematic method nurses use to provide individualized patient care. It consists of five steps: assessment, diagnosis, planning, implementation, and evaluation. Each step involves prioritizing patient needs and ensuring that the most critical issues are addressed effectively. Table 12.2 illustrates this process using the example of a patient, Mrs. Smith, who has been admitted with congestive heart failure.
| Step | Explanation | Connection to Prioritization |
|---|---|---|
| Assessment | The first step in the nursing process involves gathering relevant data about the patient, including medical history, medication regimen, and lifestyle factors. | The nurse should focus on Mrs. Smith’s most pressing symptoms, such as difficulty breathing and fluid retention. |
| Diagnosis | Based on the assessment, the provider determines the cause of the health issue. This step helps in setting clear goals for the patient’s treatment. | For Mrs. Smith, a primary nursing diagnosis might be “impaired gas exchange related to congestive heart failure.” This issue should take precedence over less urgent ones. |
| Planning | The planning phase involves setting short-term (e.g., can be achieved within hours to days) and long-term (e.g., can be achieved over weeks to months) goals and determining the course of action for treating the issue. | The plan should be tailored to address the most critical needs first. For Mrs. Smith, high-priority goals include stabilizing her breathing and managing her heart function. Lower-priority goals might involve education about lifestyle modifications and long-term management of her condition. |
| Implementation | During this phase, the prioritized care plan is put into action. | High-priority interventions for Mrs. Smith might include administering diuretics to manage fluid retention and providing oxygen therapy to improve her breathing. Secondary interventions could involve nutritional counseling and mobilization strategies as her condition stabilizes. |
| Evaluation | In the final step, the nurse evaluates the patient’s response to the treatment plan. The care team can then determine whether the plan needs to be adjusted. | Prioritizing in this step involves assessing whether the high-priority goals for Mrs. Smith, such as improved breathing and reduced edema, have been achieved. |
The Clinical Judgment Measurement Model (CJMM), a framework designed to assess and evaluate the clinical judgment skills of nurses, intersects with each phase of the nursing process (Figure 12.5), enriching and refining nurses’ clinical decision-making skills. During the assessment phase, CJMM emphasizes gathering thorough patient data and recognizing subtle cues to inform subsequent clinical judgments and interventions. In the diagnosis phase, CJMM guides nurses in formulating precise nursing diagnoses, integrating assessment data and evidence-based practice. The CJMM supports nurses in developing holistic care plans in the planning phase, prioritizing interventions, and collaborating with interdisciplinary teams. During implementation, CJMM assists in executing care plans with adaptability and incorporating evidence-based interventions. In the evaluation phase, CJMM facilitates a comprehensive review of patient responses, enabling critical analysis and continuous quality improvement. Integrating CJMM enhances nurses’ ability to promote patient safety, deliver high-quality care, and make informed clinical judgments throughout patient care delivery.
Analyzing Data Collected during the Assessment
Analyzing the data collected during a nursing assessment is a critical step in the nursing process. It involves interpreting the gathered information to make informed decisions about patient care. This analytical process requires nurses to identify significant clues, make inferences, recognize patterns, and apply both inductive and deductive reasoning. These skills enable nurses to translate assessment data into actionable insights, forming the basis for accurate nursing diagnoses and effective care plans.
Clues and Inferences
Clues are pieces of observable, measurable, and factual information obtained during the assessment process. These may include vital signs, physical examination findings, patient statements, and laboratory results. For example, if a patient reports increased shortness of breath and the nurse observes swelling in the legs, these clues might suggest heart failure.
Inferences are the conclusions drawn from these clues. Nurses use critical-thinking skills to analyze the data, recognize patterns, identify deviations from the norm, and consider the significance of each finding in the context of the patient’s overall health. In this case, the nurse might infer that the patient’s heart failure is worsening. Making accurate inferences based on observed clues is crucial for identifying a patient’s health issues and planning appropriate interventions.
Patterns
Recognizing patterns in the assessment data is another crucial aspect of analysis. Patterns refer to recurring themes, trends, or relationships observed across various aspects of the assessment. To analyze patterns effectively, nurses compare and contrast data points collected over time or across different assessment parameters. They look for consistency or inconsistency in the findings, noting any deviations from the expected or normal range. For instance, a pattern of increasing blood pressure readings over several visits might indicate poorly controlled hypertension. Recognizing these patterns helps nurses anticipate and prevent complications, adjust treatments, and advocate for changes in the care plan.
Inductive Reasoning
Making generalizations based on specific observations is known as inductive reasoning (Burke, 2023). For example, if a nurse observes a patient’s wound is not healing despite standard care and knows that similar cases have improved with a different treatment, then the nurse may conclude that their patient may benefit from an alternative treatment. This form of reasoning allows nurses to formulate hypotheses about a patient’s condition and potential responses to treatment based on observed trends and outcomes.
Deductive Reasoning
In deductive reasoning, general principles are applied to make conclusions about specific cases (Burke, 2023). For instance, knowing that immobility increases the risk of pressure ulcers, a nurse caring for a bedridden patient will deduce the need for regular repositioning and skin assessments. This type of reasoning allows nurses to apply established knowledge and guidelines to individual patient scenarios, ensuring evidence-based and personalized care.
