TEST 3 Flashcards
Strain
muscle pull or tear of ligaments and tendons
Sprain
Twisting, stretching or tearing of ligaments
Ex: Knee strain
RICE
Rest, Ice, Compression, Evelate
Severe burning pain, frequent changes in skin from hot and dry to cool and clammy shiny skin that is growing more hair in the injured extremity
CRPS- complex regional pain syndrome
When is heat advised in a patient who has sprain or contusion
after 2 days since inflammation is no longer likely to increase. Heat relives localized edema and improves circulation
What is a late sign of compartment syndrome
pulselessness- it signifies lack of distal tissue perfusion
Which factor may contribute to compartment syndrome?
Hemorrage
how long does a plaster cast need to dry
72 hour
Plaster cast
needs 72 hours to dry, be careful when handling to avoid pressure points
Fiberglass cast
Dries within 15 minutes, light weight and does give off heat while drying, water proof liner
6 P’s
Pallor Pulselessness Paresthesia Paralysis poikilothermia
It is important to call your provider when having a cast if..
you notice cyanotic, skin breakdown, notice soft spots around cast, drainage and odor
Fat embolism syndrome:
Occurs at the time of a fracture, fat globules can diffuse from the marrow into the bloodstream and block off the lungs, kidneys and brain.
Highest risk for FES
fracture of long bones, hips, crash injuries, multiple fractures
S/S of FES can occur…
12-72 hours after
tachycardia, SOB, confusion, chest pain, cyanosis, petechiae from nipple to face, high ESR
MEDICAL EMERGENCY–>SUPPLY OXYGEN
What labs should be monitored with a fracture,
6 P’s, coagulation labs, vital signs, know weight baring status
DIC
widespread hemorrhage, microthrombosis with ischemia, bleeding from mucous membranes, ventricular sites, GI and urinary.
Bucks traction
skin traction, make sure there is no pressure ulcers that occur, teach patients to try and shift weight in bed, look for nerve damage of circulation problems.
Bucks traction is used for
Lower limb extremities to help with pain!
PET scan
used to assess cancer and metastasis. Forms “hot spots” in an event of a tumor. Have the patient be NPO for 4-6 hours before. Must lie still for 90 minutes.
Uses a radioactive substance
Ventilation Perfusion Lung Scan (assesses and primarily used for…)
assesses the blood flow and airflow in the lungs
Primarily used for pulmonary embolis
Measure the amount of radiopaque substance in the lungs (normal should be 1:1)
What is the purpose of a bronchoscopy?
diagnosis of lung conditions–biopsy–> treatment of lung conditions such as removal of small lesions,
Bronchoscopy provides a direct visualizations of..
the lungs and airways by fiber optics
Nursing care for bronchoscopy..
NPO for 6 hours, pre op meds, intra procedure: conscious sedations monitoring, spray zylocaine.
NPO until gag reflex returns, VS stable.
Complication of bronchoscopy
hemorrage and aspiration
Sputum culture:
best early in the morning, patient should rinse mouth with water but not brush teeth since it can affect the results, clear nasal mucus by blowingn ose, take 2 of 3 deep breaths and cough deeply from the diaphragm, expectorate into sterile specimen container.
Antibiotic therapy should be on hold until a sputum culture is given TRUE OR FALSE
TRUE- YOU CANNOT TELL WHICH BACTERIA IT IS IF AB IS TAKEN BEFORE
Thoracentesis
diagnostic test given to assess the presence of infectious organisms or cancer cells. Treatment for large pleural effusions that diminish lung function
Hgb value
12-16
Hct
35-50
platelet count
150,000-400,000
What might be elevated in COPD?
H&H
Elevated H&H with COPD because the body is trying to compensate. The body doesn’t have enough oxygen so it is made more .
WBCS will be elevated if…
inflammation or infection
Neutrophils
Acute infection
Lymphocytes will be elevated if..
chronic or inflammation
Monocytes will be elevated..
in bacterial infections but will be later
Eosinophils will indicate
allergies
Bands can indicate
immature WBC
RBC and H&H can be indicated in
respiratory disorders
Low H&H you would worry about..
poor oxygenation
Atelectasis is when
there is closure or collapse of the alveoli,
Atelectasis is commonly seen in what type of patients (3).
elderly, post op, bed ridden
what is key to not getting atelectasis..
PREVENTION (using IS, T, C, DB, early ambulation, getting out secretions, increase fluids)
Signs and symptoms of atelectasis
low grade fever, cough, sputum production, tachypnea, diminished breath sounds, fine crackles.=, dyspnea, cyanosis, pleual pain in severe cases.
can occur 48 hours post op
What is the most common type of atelectasis
obstructive, this occurs when patients are not deep breathing, and can be due to mucus and alveoli not being filled
XR for atelectasis shows :
patchy, airless or consolidated areas
Pneumonia can occur due to
atelectasis
Exudate can be formed from..
WBC, RBC, Fibrin
Bacterial pneumonia S/S:
pleuritic pain, chills, fever, cough with purulent sputum, cyanosis, dyspnea, fine crackles, diminished lung sounds, wheezes, friction rub
Viral pneumonia S/S:
HA, fever, fatigue, malaise, aching, dry cough
Hospital acquired pneumonia can occur within how many days?
48 hours after admission
most often gram negative
Bronchopneumonia
patchy areas of consolidation, can occur in both lungs
lobar pneumonia
entire lobe is consolidated (one love) such as Right lower lobe pneumonia
general signs and symptoms of pneumonia
fever sob fine crackles tachypnea increase pulse and RR consolidation- sputum dullness in percussion pleuritic pain egophony confusion in elderly
How do we diagnose pneumonia
ABG, XR, labs, h&p, bronchoscopy
pulmonary embolism
pleuritic pain, SOB, cough, hemoptysis, dypnea, tachypnea, anxiety, tachycardia, diaphoresis, hypoxemia, syncope, shock
Diagnostic test for PE
XR, ABG, ECG, CT, pulmonary angiography, ventilation/ perfusion scanner, d-dimer
PE medication:
anticoagulants: 5-7 days such as heparin
Coumadin 3-6 months
Thrombolytics: streptokinase
Complications for bucks traction:
infection, skin intergrity, UTI, respiratory issues, mental health issues, muscle atrophy, constipation, aspiration, osteoporosis
surgery for highest risk for DVT
Total knee replacement
stage 1: primary infection of AIDS
Window period 1A:
period from infection exposure to appearance of antibodies, tests negative for antibodies, may have symptoms but not be associated with HIV, (fever, fatigue and rash)
Stage 1B: antibodies begin to develop in 2-3 weeks, CD4 count >500
Stage 2: Latent phase of HIV
200-499 CD4 count. or CD4 and t-lymphocytes 14-28%
Tests positive for HIV
Cd4 and t-lymph fall overtime
symptomatic conditions develop that are NOT associated with AIDS
Stage 3: AIDS phase
At CD4 count of
immune system is compromised
stage 3
Remains stage 3 even if Cd4 and T cells increase with treatment
Is HIV screening recommended for all persons seeking evaluation and treatment for STIs
YES
