NUR255 EXAM 1 QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS GRADED A++
tidal volume
vol inhaled + exhaled with normal quiet breathing (500mL)
inspiratory reserve vol vs expiratory reserve vol
IRV - max amount that can be inhaled over and above a normal inspiration 2000-
3100mL
ERV - max amount that can be exhaled following a normal exhalation 1000mL
vital capacity
TOTAL amount of air that can be exhaled after maximal inspiration 4500mL
IRV+TV+ERV = VC
pathway that shows the role of hemoglobin related to oxygenation
a. What happens if a patient has a low iron count
b. Describe the physical presentation of the patient with low O2 saturation
hemoglobin is a protein with iron that can bind to 4 O2 molecules and transport it from
the lungs to tissues
,so low iron count = low O2 sat
S/S:
SOB
headache
dizzy
chest pain
confused
high BP
blue skin
high HR
runny nose in cold/flu virus
causes cells to swell/die which allows fluid to escape
bronchovesicular sound
heard at the level of the primary bronchi
soft
vesicular sounds
soft, low-pitched sounds that doctors can hear throughout the lungs, primarily when a
person breathes in.
below second rib at base of lungs
tracheal sounds
,harsh and sound like air is being blown through a pipe
over trachea
bronchial sounds
loud, harsh breathing sounds with a midrange pitch
over the large airways in the anterior chest near the second and third intercostal spaces
What clinical manifestations will you find for the patient with a nasal infection
congestion
postnasal drainage
runny nose
mucus
heavy head
What is the medical term for a patient who stops breathing for a period of time?
(this could last from a few seconds to a few minutes)
apnea
pneumonia findings
cough with phlegm or pus, fever, chills, and difficulty breathing
pneumothorax findings
unequal breath sounds, hyperresonance with percussion over the chest wall, and
decreased wall movement on the affected side of the chest
pleural effusion findings
, Dullness to percussion, decreased tactile fremitus, and asymmetrical chest expansion,
with diminished or delayed expansion on the side of the effusion
purpose + what happens + nursing edu
Pulmonary angiography
- look at blood flow in lungs
-look for blood clots
-inject contrast dye into blood vessels
-don't eat or drink 8hrs b4
Pulmonary ventilation
purpose + what happens + nursing edu
- make O2 available to the blood
- air flow going into lungs
- maintain client's airway
Thoracentesis
purpose + what happens + nursing edu
