Study Notes
Vital Signs Module
- The learner will be able to discuss the taking of vital signs and apply the nursing process in case studies and discussions to plan care for a patient experiencing variations in vital signs.
- Importance of taking vital signs:
- Helps us know where a patient's baseline vital signs should be
- Helps us know if there are any drastic changes from the baseline vital signs
- Components of vital signs:
- Temperature
- Pulse
- Respiration
- Blood pressure
- Oxygen saturation
- Pain scale (when relevant to the patient being assessed)
Frequency of Vital-Sign Measurement
- Frequency based on patient stability:
- Unstable/critical patient: every 5 minutes
- Stable patient: every 4 to 8 hours
- Post-op patient: every 15-60 minutes in recovery, every 15 minutes the first half hour after surgery
- Rehab floor: every shift
- Psych floor: every day
- CNA/PCA can do vital signs, but nurse should do vital signs if administering medication
Nurse's Responsibility for Vital-Sign Measurement
- Assess vitals correctly and accurately for every patient in their care
- Obtain patient's usual baseline and compare to any drastic changes
- Report drastic changes to provider or charge nurse
- Vital signs are used to monitor and evaluate patients, determine diagnosis, treatment, and plan of care
Body Temperature
- Regulated by the hypothalamus
- Set point: comfortable temperature that the brain sets for the body
- Set point can be altered by infection, allergens, or inflamed tissues
- Methods of temperature control:
- Heat loss:
- Radiation
- Conduction
- Convection
- Evaporation
- Heat production:
- Metabolism
- Shivering
- Heat loss:
Temperature-Related Terms
- Pyrexia: abnormal elevation of body temperature above 37°C (98.6°F), also known as fever
- Hyperpyrexia: extreme abnormal elevation of body temperature, needs immediate medical attention
- Hyperthermia: elevated body temperature due to inability to promote heat loss or reduce heat production
- Hypothermia: heat loss during prolonged exposure to cold, overwhelms the body's ability to produce heat
Fever
- Fever helps the body fight disease by stimulating proteins called interferon
- Should not treat fever if it's not over 102.2°F (for adults) or 104°F (for children), unless rising quickly
- Fever can trigger seizures in children
Phases of Fever
- Chill Phase: body reacts to a new set point, ends when a new set point is reached
- Signs and symptoms: shivering, blood vessels constrict, absence of sweating
- Care: assessment, blankets, fluids, nourishment, oxygen
- Fever Phase: plateau, new set point reached
- Signs and symptoms: flushed skin, warm skin, weak, muscle aches, drowsy, restless
- Care: comfort, hydration, prevent shivering, limit physical activity, oral hygiene, environmental temp control
- Flush or Crisis Phase: set point overshot or pyrogens removed, hypothalamus set point drops
- Signs and symptoms: profuse diaphoresis, less shivering, flushed warm skin, fever "breaks"
- Care: fluids, light clothing, hypothermia blanket, medication, oral hygiene, environmental temp control
Pulse
- Physiology of the pulse:
- Blood coming from the heart with every ventricular contraction
- Your heart has 4 chambers, left ventricle ejects blood to aorta, right ventricle ejects blood to pulmonary system
- Pulse rate: number of pulsations felt in a beat
- Normal pulse rates:
- Infants: 80-180 bpm
- Adults: 60-100 bpm
- Factors that increase pulse rate:
- Pain
- Stress
- Fear
- Anger
- Anxiety
- Exercise
- Decreased BP
- Increased temperature
- Low oxygen
- Medication (e.g., vasoconstrictor medications)
- Factors that decrease pulse rate:
- Heart conditioned by long-term exercise
- Hypothermia
- Chronic pain
- Negative chronotropic drugs (e.g., digitalis, beta-adrenergic and calcium channel blockers)
- Lying down
- Characteristics of pulse:
- Pulse rhythm: regular, irregular, dysrhythmia, arrhythmia
- Pulse quality or amplitude: descriptions of fullness of pulse (0, +1, +2, +3)
