quiz 1 Flashcards
The hypothalamus impact on vital signs
the hypothalamus controls body temp, senses minor changes in the body temperature. The anterior hypothalamus controls heat loss and the posterior hypothalamus controls heat production.
Newborn and infant temperature regulation
temperature control mechanisms are immature - responds drastically to changes in the environment.
they can lose up to 30% of their body eat through their head, therefore need to wear a cap to prevent heat loss.
when protected from environmental extremes, the newborns body temp is within 35.5 -37.5 degrees Celsius
Critical thinking related to vital signs
- it is the nurses responsibility to review vital sign data, interpret their significance, and critically think through decisions about interventions.
-use VS measurements to determine indication for medication administration. - Analyze the results of vital sign measurements on the basis of the pt’s condition and past health history.
-Verify and communicate significant changes in vital signs
Purpose of stethoscope
Amplifies internal body sounds from the heart, lungs, and bowels. Each sound has a “normal” frequency range that doctors listen for
purpose of thermometer
measure body temperature. 96.8-100.4 F (36-38 degrees Celsius)
Sphygmomanometer
Measures blood pressure.
Systolic < 120 mmHg
Diastolic <80 mmHg
Routes to assess temperature and range
Average temperature range: 36° to 38°C (96.8° to 100.4°F)
Average oral/tympanic: 37°C (98.6°F)
Average rectal: 37.5°C (99.5°F)
Axillary: 36.5°C (97.7°F)
Temporal 37C (98.6F)
Technique for checking radial pulse
radial or thumb side of the forearm at the wrist. Common site used to assess character of pulse peripherally and status of circulation to hand.
checking carotid pulse
Along medial edge of sternocleidomastoid muscle in neck. Easily accessible site used during physiological shock or cardiac arrest when other sites are not palpable
technique for checking pedal pulse
posterior tibial- (inner side of the ankle, below medial malleolus). Dorsalis Pedis (top side of the foot, medially)
Strategy to obtain respirations
range is 12-20 breaths per min.
Do not let a patient know that you are assessing respirations. Quietly observe the patient’s breathing and when appropriate begin to count the rate. A patient aware of the assessment can alter the rate and depth of breathing. Assess respirations immediately after measuring pulse rate, with your hand still on the patient’s wrist as it rests over the chest or abdomen. In children, measure respirations first, before other vital signs.
Impact of alcohol, smoking, and caffeine on VS
Alcohol: Increase heart rate, Increase BP, weaken heart muscles, and irregular heartbeat.
Smoking: Smoking results in vasoconstriction, a narrowing of blood vessels. BP rises when a person smokes and returns to baseline about 15 minutes after stopping smoking.
Caffeine: Can elevate Heart rate and blood pressure.
Proper action and documentation when medication administration parameters are not met
Document name of medication, dose, route, and time administered on MAR. Document patient’s response in nurses’ notes of MAR in the electronic health record (EHR) or chart.
apical pulse site
@ 5th intercostal space, down from left clavicle (heart side)
popliteal pulse site
behind knee
