Common cold is cause by

Strep infections predispose one to
acute rheumatic fever and inflammatory disease of the heart, joints and central nervous system, acute glomerulonephritis and acute kidney infection
Nurse alert with toothbrushes of + strep
toothbrushes should be discarded if positive stretococcal infection
adenoids
aka pharyngeal tonsils Adenoids are part of the immune system. Like all lymphoid tissue, they trap infectious agents like viruses and bacteria, and they produce antibodies. Since the adenoids are located at the back of the nasal airway, they provide defense against inhaled substances. This function decreases with age as the adenoids shrink. Because adenoids do ordinarily shrink by late childhood, the problems caused by enlarged adenoids rarely occur in adults.

staphyloccus aureus, M. catarrhalis, and Haemophilus influenza
postural drainage
Drainage used in bronchiectasis and lung abcess. The patient's body is positioned so that the trachea is inclined downward and below the affected chest area [1]. Postural drainage is essential in treating bronchiectasis and patients must receive physiotherapy to learn to tip themselves into a position in which the lobe to be drained is uppermost at least three times daily for 10-20 minutes.
Chest physiotherapy
Chest physiotherapy - performed by respiratory therapists whereby breathing is improved by the indirect removal of mucus from the breathing passages of a patient. Techniques include clapping or percussion: the therapist lightly claps the patient's chest, back, and area under the arms.

True
True/False Status asthmaticus is a medical emergency that can result in repiratory failure and death if untreated. The child who sweats profusely, remains sitting upright and refuses to lie dow is in severe respiratory distress, Also the child who suddenly becomes agitated, or the agitated child who suddenly becomes quiet, may be weriously hypoxic and requires immediate intervention
true
True/False dehydration should be corrected slowly, overhydration can increase the accumulation on interstitial pulmonary fluid to exacerbate small airway obstruction
true
Statis Asthmaticuas
Status asthmaticus is an acute exacerbation of asthma that does not respond to standard treatments of bronchodilators and corticosteroids. Symptoms include chest tightness, rapidly progressive shortness of breath, dry cough and wheezing. The lung failure means that oxygen can no longer be provided, carbon dioxide can no longer be eliminated, which leads to acidosis.

funnel chest
occurs more often in men than women, manifested with depression in the lower sternum, can cause murmers and may depress the heart and great vessels, seen in Rikets and Marfan's syndrome
pigeon chest
Pigeon chest is noticeable because of outward projection of the breastbone and/or neighbouring ribs. There is indrawing of the sides of the chest wall and often asymmetry, which can reduce the volume of the chest and place abnormal loads on the thoracic spine.
Cheyne stokes
Cheyne-Stokes respiration is an abnormal pattern of breathing characterized by periods of breathing with gradually increasing and decreasing tidal volume interspersed with periods of apnea. In cases of increasing intracranial pressure, it is often the first abnormal breathing pattern to appear.
Kussmaul breathing
