Health Assessment

27-2Copyright 2004 by Delmar Learning, a division of Thomson Learning, Inc.

Preparing for the Health Assessment

Environment• Ensure privacy• Quiet, warm room• Special needs of the client• Surface for placement of equipment



Equipment• Maintenance• Isolation precautions• Adequate number of gloves



Positioning • Ensures accessibility to the body part being

assessed.

Draping• Prevents chilling.• Prevents unnecessary exposure.


Conducting the Health and Physical Assessment

Aimed at establishing a data base against which subsequent data can be compared.• Comprehensive Assessment (head to toe)• Assessment of a body part (focused)• Assessment of a body system (focused)


Conducting the Health and Physical Assessment

Conducted in an aseptic, systematic, and efficient manner.

Requires the fewest position changes for the client.


General Survey

Initial Observations • Client’s physical appearance• Mood and behavior• Speech patterns and voice intonations• Signs and symptoms of distress• Vital signs• Height and weight


General Survey

Special Considerations• Elderly clients• Disabled clients• Abused clients


Measurement of Height and Weight

Height• Height is expressed in inches (in), feet (ft),

centimeters (cm), or meters (m).• A scale for measuring height is usually

attached to a standing weight scale.• Infant’s length is measured from vertex (top)

of head to soles of feet while infant is lying with knees extended.



Weight• Measurement of weight is expressed in

ounces (oz), pounds (lb), grams (g), or kilograms (kg).

• Daily weights should be obtained at the same time of the day, on the same scale, with the client wearing the same type of clothing.



Weight• Types of scales available include chair,

stretcher, bed, and platform scales.• Infants are weighed on platform or cradle

scales.



Nursing Considerations• Accurate recordings are necessary for drug

dosage calculations and evaluation of effectiveness of drug, fluid, and nutritional therapy.



Documentation• Height and weight are recorded on the

admission assessment form.• Daily weights are usually recorded on the

vital signs record.• Measurements taken at different times or on

different scales should be recorded.


Vital Signs

The taking of vital signs refers to measurement of the client’s body temperature (T), pulse (P) rate, respiratory (R) rate, and blood pressure (BP).

Vital signs are the first step in the physical examination.


Vital Signs

Assessment of vital signs provides specific data regarding the client’s current condition.

Variations from baseline values may indicate potential problems with the client’s health status.


Vital Signs

The sequence for recording vital sign measurements in the nurses’ notes is T-P-R and BP.

Vital signs are plotted on graphic forms that facilitate data comparison at a glance.


Thermoregulation

The body’s physiological function of heat regulation to maintain a constant internal body temperature


Physiologic Function

Thermoregulation• The heat of the body is measured in units

called degrees.• The core internal temperature of 98.6

degrees Fahrenheit (F) does not vary more than 1.4 degrees F.

• Core internal temperature is higher than the skin and external temperature.


Thermoregulation

Heat Production• Basal Metabolic Rate (BMR)• Vasodilation• Vasoconstriction• Piloerection


Thermoregulation

Heat Loss• Radiation• Conduction• Convection• Evaporation

Insensible Heat Loss


Thermoregulation

Behavioral Control of Body Temperature• The person makes appropriate

environmental adjustments in response to the body’s signaling conditions of either being overheated or too cold.


Respiration

Respiration is the act of breathing. Terms related to respiratory function are:

• External respiration• Internal respiration• Inspiration• Expiration• Vital capacity


Respiration

Major physiological pulmonary functions are:• Ventilation• Circulation• Diffusion• Transport• Regulation


Hemodynamic Regulation

The circulatory system transports nutrients to the tissues, removes waste products, and carries hormones from one part of the body to another.



Systemic Circulation• Arteries• Arterioles• Capillaries• Veins• Venules



Cardiac Cycle• Systole• Diastole

Stroke Volume Cardiac Output Compensatory Mechanisms



Pulse• The pulse is caused by the stroke volume

ejection and distension of the walls of the aorta.

• The bounding of blood flow in an artery is palpable at various points in the body (pulse points).



Blood Pressure • Measurement of pressure pulsations exerted

against the blood vessel walls during systole and diastole


Blood Pressure

Systolic Pressure • Maximum pressure exerted against arterial

walls during systole

Diastolic Pressure • Pressure remaining in the arterial system

during diastole



Hemodynamic regulators for blood pressure control are:• Blood volume• Cardiac output• Peripheral vascular resistance• Viscosity


Factors Influencing Vital Signs

Age Gender Heredity Race Lifestyle Environment


Factors Influencing Vital Signs

Medications Pain Exercise Anxiety and Stress Postural Changes Diurnal (daily) Variations


Assessing Body Temperature

Temperature Scales• Centigrade or Fahrenheit scales are used to

measure temperature.• Glass or electronic thermometers are used.

Temperature Sites• Oral• Rectal• Axillary


Assessing Body Temperature

Alterations in Body Temperature• Pyrexia• Hyperthermia• Heat Exhaustion• Heat Stroke• Hypothermia• Frostbite


Assessing Pulse

Sites• The most accessible peripheral sites are the

radial and carotid sites.• The carotid site should always be used to

assess the pulse in a cardiac emergency.


Assessing Pulse

A peripheral pulse is palpated by placing the first two fingers on the pulse point with moderate pressure.

A Doppler ultrasound stethoscope is used on superficial pulse points.

A stethoscope is used to auscultate the heart’s rate and rhythm.


Assessing Pulse


Assessing Pulse

A pulse deficit occurs when the apical pulse rate is greater than the radial pulse rate.

Pulse Characteristics• Pulse quality• Pulse rate (bradycardia, tachycardia)• Pulse rhythm (dysrhythmias)• Pulse volume


Assessing Pulse

Nursing Considerations• An irregular pulse rate, if not previously

documented, should be reported immediately.

• Clients on certain cardiac medications may need to monitor their pulse rate.

• Routine exercise lowers resting and activity pulses.


Assessing Respirations

Sites• Observation of chest wall expansion and

bilateral symmetrical movement of the thorax

• Placement of back of hand next to client’s nose and mouth to feel expired air



Rate is counted by number of breaths taken per minute.

Observation of thoracic and abdominal movements includes:• Depth, rhythm, and symmetry• Costal (thoracic) breathing• Diaphragmatic breathing



A stethoscope is used to auscultate breath sounds throughout the respiratory system.



Dyspnea, Bradypnea, tachypnea, apnea Hypoventilation Hyperventilation


Assessing Respiratory Function

Cyanosis• Bluish appearance in the nail beds, lips, and

skin• Reduced oxygen levels in the arterial blood



Clients with respiratory alterations require additional nursing assessment.• Pulse oximetry • Apnea monitor


Assessing Blood Pressure

The direct method of measuring blood pressure requires an invasive procedure.

The indirect method requires use of the sphygmomanometer and stethoscope for auscultation and palpation as needed.



The most common site for indirect measurement is the client’s arm over the brachial artery.

Accurate measurement requires the correct width of the blood pressure cuff as determined by the circumference of the client’s extremity.



Korotkoff sounds are five distinct phases of sound heard with a stethoscope during auscultation.

The forearm or leg sites can be palpated to obtain a systolic reading when the brachial artery is inaccessible.



Hypotension refers to a systolic blood pressure less than 90 mm Hg or 20 to 30 mm Hg below the client’s normal systolic pressure.

Hypertension refers to a persistent systolic pressure greater than 135 to 140 mm Hg and a diastolic pressure greater than 90 mm Hg.



Orthostatic Hypotension (postural hypotension)• Sudden drop in systolic pressure when client

moves from a lying to a sitting to a standing position



False Readings• Clients who have recently eaten, ambulated,

or experienced an emotional upset• Improper cuff width• Improper technique in deflating cuff• Improper positioning of extremity• Failure to recognize an auscultatory gap

age, sex, race and body part.• Vellus• Terminal hair

inspection and palpation. • The client’s face has its own unique

characteristics related to race, state of health, emotions, environment.
