D443 Health Assessment - Set 3 - Part 1

Correct Answer: Subjective data provided directly by the patient about their experience

Subjective data consists of information the patient reports about their own symptoms, feelings, and perceptions that cannot be directly observed or measured by the nurse. The patient's description of burning stomach pain worsening after eating is a symptom reported by the patient, making it subjective data. Objective data, by contrast, is measurable and observable by the examiner, such as vital signs or physical findings. Because this information came directly from the patient rather than another individual or a test result, it is classified as subjective primary-source data.

Correct Answer: Secondary source of the health history

The patient is always considered the primary source of health history information. When the patient cannot provide reliable information, as with advanced dementia, family members, caregivers, medical records, or other clinicians become secondary sources. The daughter providing the history is therefore a secondary source. Documenting the source is important because information obtained secondhand may be incomplete or interpreted differently than the patient would report, and it affects how the nurse weighs and verifies the data.

Correct Answer: 'Can you tell me what was happening just before you fainted?'

Open-ended questions invite the patient to respond in narrative form and provide rich, detailed information in their own words, which is ideal early in an interview when gathering the history of the present illness. Asking the patient to describe what was happening before fainting is open-ended and allows the patient to share context the nurse might not think to ask about. The other options are closed-ended questions answerable with a single word such as 'yes' or 'no,' which are useful for clarifying specific facts but limit the depth of information gathered.

Correct Answer: Radiation of the symptom

In the OLDCARTS mnemonic (Onset, Location, Duration, Character, Aggravating/Alleviating factors, Radiation, Timing, Severity), radiation refers to whether the symptom spreads or travels from its original location to other areas of the body. Asking whether chest pain spreads to the arm or jaw specifically evaluates radiation, which is clinically significant because radiating chest pain can indicate cardiac ischemia. Onset addresses when the symptom began, timing addresses its pattern over time, and severity addresses its intensity, none of which are captured by asking about the spread of pain.

Correct Answer: Physical appearance, body structure, mobility, and behavior

The general survey is the nurse's overall first impression of the patient and encompasses four broad categories: physical appearance (including apparent age, level of consciousness, skin color, and facial expression), body structure (stature, nutrition, symmetry, and posture), mobility (gait and range of motion), and behavior (facial expression, mood, speech, dress, and hygiene). These observations begin the moment the nurse meets the patient. The other options describe vital signs, physical examination techniques, and integumentary components, which are distinct assessment activities rather than the components of the general survey.

Correct Answer: A behavioral pain scale that scores observable indicators such as facial expression and body movement

When a patient cannot self-report pain, such as an intubated or cognitively impaired adult, the nurse must rely on validated behavioral pain assessment tools that score observable indicators like facial expressions, body movements, muscle tension, and ventilator compliance. Self-report is considered the gold standard for pain, but it requires the patient to communicate. The numeric rating scale and Wong-Baker FACES scale both require patient participation, which an intubated sedated patient cannot provide, and delaying assessment leaves pain untreated, which is unacceptable given pain's status as the fifth vital sign.

Correct Answer: The Wong-Baker FACES pain rating scale

The Wong-Baker FACES pain rating scale uses a series of cartoon faces ranging from a happy, smiling face to a crying face, allowing young children who can understand the concept of comparison to point to the face that best matches their pain. It is validated for children as young as three years and is ideal for a cooperative six-year-old. Numeric and visual analog scales require abstract reasoning about numbers or proportional lines that many young children have not yet developed, and purely behavioral scales are reserved for children too young or unable to self-report.

Correct Answer: Two-plus, indicating a normal pulse

On the standard 0 to 4+ pulse amplitude scale, a grade of 2+ represents a normal, expected pulse that is easily palpable. A grade of 0 indicates an absent pulse, 1+ indicates a diminished or thready pulse that is difficult to feel, 3+ indicates an increased or full pulse, and 4+ indicates a bounding pulse that may be a sign of hyperdynamic circulation. Accurate documentation using this scale allows consistent communication of perfusion status among clinicians and helps track changes in a patient's circulatory condition over time.

Correct Answer: The fifth intercostal space at the left midclavicular line

The apical pulse is best auscultated at the point of maximal impulse, which in a healthy adult is located at the fifth intercostal space at the left midclavicular line, corresponding to the apex of the heart. This site provides the clearest heart sounds for counting a full one-minute apical rate, which is especially important before giving medications such as digoxin. The second intercostal space at the right and left sternal borders correspond to the aortic and pulmonic auscultation areas, respectively, and are not used for counting the apical rate.

Correct Answer: Pulse deficit

A pulse deficit is the numerical difference between the apical and radial pulse rates measured simultaneously, in this case 14 beats per minute. It occurs when some cardiac contractions are too weak to generate a palpable peripheral pulse, meaning not every heartbeat produces an effective stroke that reaches the radial artery. A pulse deficit often signals cardiac dysrhythmias such as atrial fibrillation and requires further evaluation. Pulse pressure refers to the difference between systolic and diastolic blood pressure, while pulsus paradoxus and pulse amplitude describe other distinct cardiovascular phenomena.

Correct Answer: 52 millimeters of mercury

Pulse pressure is calculated by subtracting the diastolic blood pressure from the systolic blood pressure. For a reading of 138/86, the pulse pressure is 138 minus 86, which equals 52 millimeters of mercury, a value within the normal range of approximately 40 to 60. Pulse pressure reflects the force the heart generates with each contraction and the compliance of the arteries. A widened or narrowed pulse pressure can indicate underlying cardiovascular conditions, so calculating it correctly is a useful part of interpreting blood pressure findings.

Correct Answer: 12 to 20 breaths per minute

The normal resting respiratory rate for a healthy adult is 12 to 20 breaths per minute. A rate below 12 is termed bradypnea, and a rate above 20 is termed tachypnea, both of which warrant further assessment for underlying causes such as respiratory, metabolic, or neurological conditions. Rates of 30 to 40 breaths per minute are normal for newborns and young infants, whose respiratory rates are considerably faster than adults. Knowing age-appropriate normal ranges allows the nurse to accurately identify abnormal breathing patterns that require intervention.

Correct Answer: Tachycardia, a faster than normal heart rate

A resting adult heart rate above 100 beats per minute is classified as tachycardia. The normal adult resting heart rate ranges from 60 to 100 beats per minute, so a rate of 112 exceeds the upper limit and represents tachycardia. Bradycardia, by contrast, is a rate below 60 beats per minute. Because the patient denies obvious causes such as exertion, caffeine, or anxiety, the nurse should investigate other potential causes such as fever, dehydration, pain, or an underlying cardiac condition. Pulse deficit refers to an apical-radial rate difference, which is unrelated to classifying the rate itself.

Correct Answer: Inspection, palpation, percussion, auscultation

For most body systems, the standard sequence of physical examination is inspection, palpation, percussion, and auscultation. The nurse first inspects visually, then uses touch to palpate, then percusses to elicit sounds and assess underlying structures, and finally auscultates with a stethoscope. This progression moves from the least to the more invasive techniques and allows visual observation to guide subsequent steps. The important exception to this sequence is the abdominal examination, where auscultation is performed before palpation and percussion to avoid altering bowel sounds.

Correct Answer: Inspection, auscultation, percussion, palpation

The abdominal examination follows a modified sequence of inspection, auscultation, percussion, and palpation. Auscultation is performed before percussion and palpation because manipulating the abdomen through touch or tapping can stimulate or alter bowel motility, producing falsely increased or altered bowel sounds. By listening first, the nurse obtains an accurate assessment of the patient's true bowel sounds. Inspection still comes first, as visual observation of contour, symmetry, and skin does not disturb the underlying organs. This exception is unique to the abdomen among the major body systems.

Correct Answer: Resonance, a low-pitched hollow sound

Percussion over normal, air-filled lung tissue produces resonance, a low-pitched, hollow sound that reflects the air content of healthy lungs. Different densities of tissue produce characteristic sounds: flatness occurs over dense tissue such as bone or muscle, dullness occurs over solid organs like the liver, and tympany is a loud, drum-like sound heard over air-filled hollow organs such as the stomach or intestines. Recognizing resonance as the expected finding over the lungs allows the nurse to detect abnormalities, such as the dullness of consolidation in pneumonia or the hyperresonance of trapped air in emphysema.

Correct Answer: Tympany

Tympany is a loud, high-pitched, drum-like percussion sound produced over air-filled hollow organs such as the stomach and intestines. Because the gastric air bubble in the left upper quadrant contains air, percussion over this area normally yields tympany. Dullness is heard over solid, dense organs such as the liver or a full bladder, flatness is heard over very dense tissue such as bone, and resonance is characteristic of air-filled lung tissue. Recognizing the expected tympany over the stomach helps the nurse identify abnormal findings, such as dullness that might suggest a mass or fluid.

Correct Answer: The dorsal, or back, surface of the hand and fingers

The dorsal surface of the hand and fingers is the most sensitive to temperature because the skin there is thinner, making it best suited for detecting warmth or coolness of a patient's skin. Different parts of the hand are optimized for different assessments: the finger pads and fingertips are most sensitive to fine tactile discrimination such as texture, pulsations, and lymph nodes, while the ulnar surface and base of the fingers, where bone is close to the skin, best detect vibration such as tactile fremitus. Using the correct part of the hand improves the accuracy of palpation findings.

Correct Answer: Approximately 1 centimeter

Light palpation involves gently depressing the skin approximately 1 centimeter (about half an inch) and is used to assess surface characteristics such as texture, tenderness, temperature, moisture, and pulsations. It is always performed before deep palpation because it is less likely to cause discomfort and helps identify areas of tenderness to approach cautiously. Deep palpation, by contrast, depresses the tissue approximately 4 to 5 centimeters and is used to assess organs and masses. Beginning with light palpation builds patient trust and prevents guarding that could obscure deeper findings.

Correct Answer: The bell, placed lightly against the skin

The bell of the stethoscope, applied lightly to the skin, is best for detecting low-pitched sounds such as certain heart murmurs, extra heart sounds like S3 and S4, and bruits. Pressing the bell too firmly stretches the skin and causes it to function like a diaphragm, filtering out low frequencies. The diaphragm, pressed firmly, is best for high-pitched sounds such as normal heart sounds, breath sounds, and bowel sounds. Selecting and applying the correct stethoscope endpiece with the proper pressure is essential for accurately identifying the sound the nurse is seeking.
