cough medicines SAFE for HTN
Guaifenesin (mucinex) Dextromethorphan (robitussin)
26
Atelectasis
collapse of alveoli due to deflation or filling of fluid. s/sx: diminished breath sounds, fine crackles and hypoxia. intervention: lung expansion by use of incentive spirometer.
27
what can diagnose Asthma or COPD?
a pulmonary function tests
28
COPD: Emphysema
A chronic lung disease where the alveoli are damaged, causing difficulty of breathing and impaired ventilation.
29
what is a late stage sign of Emphysema?
barrell chest
30
COPD: Chronic Bronchitis
long term condition caused by smoking or prolong exposure to lung irritatnts. Causes overproduction of mucus and impairs gas exchange.
31
S/SX of COPD
productive cough dyspnea on exertion. labored breathing. tachypnea. wheezes & crackles diminished lung sounds.
32
Nursing intervention to improve oxygenation in respiratory distress
Tripod positioning. pursed lip breathing. effective coughing and hydration.
33
Pleural Effusion
FLUID COLLECTION between the lungs and cavity space. Medical intervention: thoracentesis or chest tube placement.
34
what confirms pleural effusion?
chest Xray ( fluid collection will look like white space)
35
Crepitus
abnormal air collection under the skin.
36
Pneumothorax (closed, open, and tension)
(collapsed lung). When AIR leaks into the space between lung and chest wall.
37
Tension Pneumothorax
AN EMERGENCY. AIR leaks into the pleural space causing PRESSURE and compressing the lungs, heart and blood vessels.
38
Chest Tube (important key notes)
- Constant bubbling in the collection chamber: indicates that air is leaked in. Occasional bubble is fine. - if chest tube gets pulled out, apply vaseline type gauze onto the chest with clear tape until it can be properly reinserted. -
39
40
Pneumonia
acute inflammation of the lungs caused by infection (bacterial, viral or fungal).
41
nursing teaching for bone scan
teach patient that radioactive is injected to vein.
42
Compartment Syndrome
increased pressure in a muscle compartment, leading to reduced blood flow (ischemia +hypoxia) and can cause tissue damage. (necrosis). Medical intervention: surgical decompression.
43
Biphosphonate
Treatment for osteoporsis. Take in the morning 30 min before food with FULL glass of water and remain upright for +30 min to prevent esophagitis.
44
Estrogen/ Raloxifene
other options for treatment of osteoporosis. LFTs should be monitored.
45
6 P's of Neurovascular Assessment
Pain Paresthesia Pulselessness Pallor Poikilothermia (feeling of cold). Paralysis (rarely).
46
Rheumatoid Arthritis (RA)
an autoimmune and progressive disease. The pain is always bilateral and systemic. Treatments: Methotrexate (DMARDS), Nsaids, glucocorticoids.
47
Antacids
offer immediate but short lasting relief. It neutralizes acid.
48
Sucralfate
A mucosal barrier that coats stomach and heals ulcer. watch out for : salicylate toxicity ringing of ears.
49
Famotidine Ranitidine Cimetidine
Histamine (H2) Antagonist that blocks acid secretion
50
Omeprazole Pantoprazole
PPI that suppress acid secretion. MOST EFFECTIVE for acid problems. Long term use can cause electrolyte imbalance (hypomagnesemia).
51
Zofran
when given IV push, PUSH SLOWY !! push 4mg over 2 minutes. important s/e: can cause dysrhythmias.
52
Promethazine (phenergan)
an antihistamine that treats allergies and nausea/ motion sickness. Can be very sedating.
53
IBS
most common digestive disorder. s/sx: frequent diarrhea or constipation, gas, abdominal pain cause - unknown. Foods can trigger an episode.
54
NGT or OGT
short term feeding tube manually inserted into NOSE ---> Mouth ---> Stomach
55
Enterostomal Tube
long term feeding tube (+30 days), surgically inserted to GI via gastrostomy or jejunostomy. ex of enterostomal tubes: PEG, PEG/J, DPEJ
56
Gastric Residual volume (GRV)
amount of liquid drained from stomach following administration of feed. Tests fir gastric emptying.
57
Parental Nutrition
Last choice. This is for patients who have major dysfunction of GI tract. complications: infection, air embolism, pneumothorax, phlebitis, hyper/hypovolemia.
58
Refeeding Syndrome
SERIOUS CONDITION of dangerous shifts in electrolytes (hypophosphatemia, hypokalemia, and hypomagnesemia) due to increased insulin secretion triggered by high carb intake.
59
Gastric Ulcer
sharp pain occurs 1-2 hours after a meal. causes hematemesis.
60
Duodenal Ulcer
burning pain occurs 2-5 hours after a meal. Pain is reduced when eating. may see melena (dark tarry stool).
61
Peptic Ulcer Disease
