Vital Signs
Fundamentals of Nursing Test #3
Term | Definition |
---|---|
Which route requires minimal patient repositioning and can be used without disturbing the patient? | Tympanic |
Which route is not required for a patient with epilepsy? | Oral |
(True/False) Rectal temperatures do not require positioning and may increase patient agitation | False; they do require positioning and may increase patient agitation |
Which temperatures need long measurement times & continuous positioning by the nurse? | Axillary |
(True/False) Oral temps are not used for patients who have has oral surgery, trauma, or shaking chills | True |
What is temporal artery temperature affected by ______. | Skin moisture (diaphoresis or sweating) |
What is the best site to assess an infant or young child's pulse? | Brachial/apical pulse; other pulses are deep and difficult to palpate |
The pulse that is easily accessible during physiological shock or cardiac arrest is ______. | Carotid |
How does a nurse obtain a radial pulse? | Place the tips of the first two or middle 3 fingers of the hand over the groove along the radial of the thumb of the patient's inner wrist |
What occludes the pulse and impairs blood flow? | Too much pressure |
What is the easiest of all vital signs to assess? | Respiratory; often the most haphazardly measured |
The difference between the systolic pressure and diastolic pressure is known as ______________. | Pulse pressure |
Which sites do you not attach the pulse oximeter to if the area is edematous or skin integrity is compromised? | Finger, ear, bridge of nose |
(True/False) The concentration of hemoglobin reflects the patient's capacity to carry oxygen. | True |
What are the normal hemoglobin ranges for males and females? | Males: 10-18 g/ 100 mL Females:12-16 g/ 100 mL |
What is the acceptable blood pressure for a healthy, middle aged adult? | 120/80 |
The normal HR for an adult is ________. | 60-100 bpm |
What increases BP in adults? | Smoking (lasts 15 minutes), caffeine (3 hours), and stress |
How long should a patient rest before BP is measured? | 5 minutes |
The normal HR for an infant is ________. | 120-160 bpm |
The normal HR for a toddler is ___________. | 90-140 bpm |
(True/False) The acceptable body temperature for older adults is 96.8 F. | True |
Who has poor vasomotor control, reduced amounts of subQ tissue, and reduced metabolism? | Older Adults |
Which thermometer is especially beneficial when used in premature infants, newborns, and children because there is no risk of injury to the child and nurse? | Temporal |
What is the acceptable RR range for a newborn? | 30-60 breaths |
Who is expected to have a RR between 30-50 breaths/min? | Infant (6 months) & Older |
Which age group has a RR range of 25-32 breaths/min? | Toddler |
A child should breathe _______________. | 20-30 breaths/min |
Which age group should breathe 16-19 breaths/min? | Adolescents |
An adult should breathe _______. | 12-20 breaths/min |
How long should you wait to allow children to recover from recent activities to check BP? | 15 min |
(True/False) Korotkoff sounds are difficult to hear in children because of low freq and amplitude. | True |
(True/False) Electronic BP measurement is not recommended w/ irregular HR or when the BP is <90 mmHg systolic. | True |
Because of their sensitivity, improper cuff placement/movement of the arm causes what tongue incorrect readings? | Electronic devices |
What should a nurse do if the pulse is irregular? | Do an apical/radial pulse assessment to detect a pulse deficit |
If pulse count differs by more than 2, what should a nurse realize? | A pulse deficit exists, which sometimes indicates alterations in CO |
What three circumstances require delays in taking oral temps? | 1) Ingestion of hot/cold foods 2)smoking 3) Receiving O2 by mask/cannula |
What should the nurse inform the patient of? | BP value & the need for perodic reassessment of the BP; Nurse should document BP readings as well as any interventions |
(True/False) Rectal temps are 0.9 degrees Fahrenheit higher than oral temps. | True |
What temps are lower than oral? | Axillary |
Who should report abnormalities to the nurse? | NAP; not allowed to retake BP or other VS after nurse has assessed the patient. |
How inaccurate pulse oximetry readings occur? | -Outside light sources -CO -Patient motion -Jaundice -Nail Polish/Artificial Nails |
What are the risk factors linked to hypertension? | -Obesity -Cigarette smoking -Heavy alcohol -High Blood Cholesterol -Continued Exposure to Stress |
(True/False) If the posterior hypothalamus senses the body's temp is lower than the set point, the body imitates heat conservation mechanisms. | True |
What reduces blood flow to the skin and extremities? | Vasoconstriction |
What controls heat loss by inducing sweating, vasodilation of blood vessels, and inhibition of heat production? | Anterior hypothalamus |
What is the transfer of heat away from the body by air movement ? | Convection |
The transfer of heat from one object to another with direct contact is called ______________. | Conduction |
The transfer of heat from the surface of one object to the surface of another w/o direct contact between the two is called __________________. | Radiation |
What is the transfer of heat energy when a liquid is changed to a gas? | Evaporation |
How much body heat does an infant lose through the head? | 30% |
When is body temperature the lowest during the day? | 1:00-4:00 AM |
How much does body temp change during the 24hr period? | 0.9-1.8 degrees |
(True/False) A fever is not usually harmful if it stays below 102.2 degrees Fahrenheit. | True |
What determines a fever? | Several temp readings @ diff times of the day compared w/ the usual value for that person @ the time |
What occurs because heat loss mechanisms are unable to keep pace w/ excess heat production that results in an abnormal rise in body temp? | Pyrexia (Fever) |
(True/False) The set point is the temperature point determined by the hypothalamus. | True |
What happens during the plateau phase of fever? | Chills subside and the person feels warm and dry as heat production and loss are equal at the new level |
What happens when a patient comes afebrile? | Fever breaks |
An elevated body temp related to the body's inability to promote heat loss or reduce heat promotion is called _____________. | Hyperthermia; does not shift in a set point |
What happens during a fever? | Cellular metabolism increases and O2 consumption rises. |
Who is responsible for assessing changes in body temp? | The Nurse |
