Exam 5: Enteral Tubes and Oxygen Flashcards
Understanding Enteral Feedings and Oxygen Supplementation
-a
without
anoxia
without oxygen
apnea
without breath
Eu
normal
Eupnea
breathing normal
euthyroid
normal thyroid
dyspnea
difficulty breathing
hyper
excessive
hypercapnia
too much Co2
hypoxemic
confusion, precursor to cyanosis or dyspnea
Types of oxygen administration
nasal cannula, nebulizer, humidifier, face mask, venturi mask
Pulse oximeter does what
measures oxygen saturation
Tenacious secretions are?
Thick and sticky
What happens with respiratory issues
retractions-breath in, muscles move inward instead of out
What should you use if the pt cannot take the oxygen off to eat?
nasal cannula
What should you use if the patient requires exact oxygen concentration
venturi mask
in the recovery room, the tongue can obstruct an airway, what should you use
nasopharyngeal airway
When is the best time of day to complete postural drainage for a pt that is having trouble mobilizing secretions
first thing in the morning before food
What is the most important chemical regulator
Co2
Oxygen is transported in the bloodstream by?
RBCs
Cilia?
located in the nose and trachea to move debris away from the throat to help cough up secretions
Gas exchange occurs where in the body?
in the alveoli
What do patients with asthma do when they are having trouble breathing?
They raise their shoulders and use their accessory muscles in the abdomen
What is a loud crowing sound when assessing an airway
stridor
If your patient cannot get sputum up, what should you do
encourage deep breathing
When an ABG is drawn from a wrist what should you do
apply pressure after
Oxygen saturation minimum is
90%
Trach care is what kind of procedure
aseptic procedure
You can safely suction a trach for how long
10 seconds
Most common Cpap side effects
skin breakdown, should use padding with the mask
Encourage a patient with pneumonia and emphysema to do what?
sit up and lean forward
IF a patient has no new inner cannula you should wash it with what?
50% saline and 50% peroxide
You have a patient with an NG tube that has a small bowel obstruction and belly extension, what type of intervention should you try
reposition the tube
When you remove an NG tube what should you do?
pinch the tube on the way out so it doesn’t get stuck or cause trauma to the stomach or esophagus
Tube feedings: what should you do?
check for residual > 100 hold/ stop feeding
Bolus feedings - check for residual
Methods to check for NG placement
Withdraw contents to check the pH , air bolus to listen for gurgling
most accurate: verify with xray
NG suctioning
low intermittent to ensure it does not stick to the stomach, mucosa and cause irriation
How to measure an NG tube for insertion
tip of the nose to tip of the ear lobe to tip of the xiphoid process
Should you start suctioning right after insertion?
No, xray should verify placement first , no feeding or suctioning should be started
When a feeding is completed in a PEG tube or NG tube what should you do
flush with water or saline.
High O2, Moderate O2, and Low O2
High: 40-50%, 12L per min
Moderate: 30% or Less 4L per min
Low: 24% or less, 1-3 L per min
