When the chest is flared and the ribs are broken in two spots, what has happened?
a. 2-3 ribs broken in one place and is confirmed by x-ray
b. Brusing, discoloration, pain, difficulty drawing a breath
Pleural effusion
a.collection fluid in pleural space usually secondary to another disease process
b.Large effusions impair lung expansion, cause dyspnea
VQ scan
Checks for ventilation capacity.
What is the continuous & non continuous breath sounds?
Continuous- Wheezing, stridor, rhonchi & inspiratory gap.
Non-continuous- Rales, crackles, or crepitus sounds
To breathe with hoarse whistling sound: to breathe with an audible whistling sound and with difficulty, usually because of a respiratory disorder such as asthma.
Rales/ Crackles
A symptomatic chest sound: an intermittent crackling or bubbling sound produced by fluid in the air passages and air sacs of the lungs and heard through a stethoscope.
Crackles can be heard in patients with pneumonia, atelectasis, pulmonary fibrosis, acute bronchitis, bronchiectasis, or post thoracotomy or metastasis ablation.
Pulmonary edema secondary to left-sided congestive heart failure can also cause rales
A coarse rattling sound somewhat like snoring, usually caused by secretion in bronchial airways. Rhonchi are breathing sounds indicative of an airway obstruction. A generalized obstruction is due to conditions such as asthma or chronic obstructive pulmonary disease, while a localized obstruction is due to a tumor, mucous, or foreign body.
Pleural rub
It's a medical sign, audible by listening to the internal sounds of the body, usually using a stethoscope on the lungs, that is used in the diagnosis of pleurisy and other conditions affecting the chest cavity.
Pleural friction rubs are the squeaking or grating sounds of the pleural linings rubbing together and can be described as the sound made by treading on fresh snow
Stable angina
heart works a little harder than normal; usually occurs with activity or stress.
Unstable angina
can lead to a very severe heart attack; chest pain my last for hours; troponin wont show; doesn't get enough blood flow or 02.
Valve replacement
a.Mechanical valves:
-Do not deteriorate

-Homograft (allograft): human valve
-Autograft: patient's own valve
a.Inflammation of the pericardium
b.Nursing diagnosis: pain
c. can lead to :

g.Bed rest
A vasodilator used to reduce preload, afterload and reduce O2 demand of the heart.
A thickening or hardening of the arterial wall which restricts blood flow.
The most common symptom of PAD is a painful muscle cramping in the hips, thighs or calves when walking, climbing stairs or exercising (Intermittent claudication!!!) It goes with rest.
-The patient may also experience cool and pale extremities when elevated and ruddy and cyanotic when in a dependent position.
-Skin may be shiny, atrophic, dry, and with sparse hair growth.
-Nails may be thickened and opaque.
-Ulcerations, gangrene, muscle atrophy, bruits, and diminished or absent pulses may be present also.
It is a slow and progressive circulation disorder. It may involve disease in any of the blood vessels outside of the heart and diseases of the lymph vessels - the arteries, veins, or lymphatic vessels. Organs supplied by these vessels such as the brain, heart, and legs, may not receive adequate blood flow for ordinary function. The legs and the feet are the most affected.
*Includes atherosclerosis, DVT, varicose veins, Thrombophlebitis, Raynaud's phenomenon, Buerger's disease (thromboangiitis obliterans) & Chronic venous insufficiency.
