Lungs & Heart - Physical Examination

COPD, which stands for Chronic Obstructive Pulmonary Disease, is an umbrella term used to describe progressive lung diseases including emphysema, chronic bronchitis, refractory (non-reversible) asthma, and some forms of bronchiectasis. This disease is characterized by increasing breathlessness.

The given correct answer lists the correct sequence of steps in a respiratory examination. Observation and inspection involve visually assessing the patient's breathing pattern, chest movement, and any visible abnormalities. Palpation involves feeling the chest and assessing for tenderness, masses, or abnormal movements. Tapping, also known as tactile fremitus, involves using the hands to detect vibrations in the chest while the patient speaks. Percussion involves tapping the chest to assess the underlying organs and structures. Auscultation involves using a stethoscope to listen to the breath sounds and any abnormal lung sounds.

Lung cancer can lead to wasting of the small muscles of the hand. This is because lung cancer can cause weakness and atrophy in the muscles due to the effects of the cancer on the body. Additionally, lung cancer can spread to other parts of the body, including the muscles, leading to further wasting and weakness.

A pneumothorax is an abnormal collection of air in the pleural space, which is the space between the lung and chest wall. This can cause symptoms such as sudden onset of sharp, one-sided chest pain and shortness of breath. The other options in the question, such as sneezing and dull chest pain, are not associated with a pneumothorax.

Cor pulmonale is a condition characterized by right ventricular enlargement and increased pressure in the pulmonary arteries. It is typically caused by long-term lung disease or pulmonary hypertension. In cor pulmonale, the right ventricle has to work harder to pump blood into the lungs, leading to a visible pulsation or heave. This can be observed as a right ventricular heave on physical examination. Therefore, cor pulmonale is the most likely explanation for the given correct answer.

Tactile fremitus refers to the palpable vibratory sensation felt on the chest wall when the patient says "ninety-nine". This sensation is transmitted through the normal lung tissue. Therefore, assessing tactile fremitus in the posterior position involves feeling for this vibratory sensation while the patient says "ninety-nine".

The given answer includes important hand signs in respiration. Cyanosis of the nails is a sign of decreased oxygenation in the blood. Nail bed fluctuation is the first sign in clubbing, which is associated with chronic respiratory conditions. Clubbing nails are another sign of chronic respiratory conditions. CO2 retention flap sign indicates elevated carbon dioxide levels in the blood. Salbutamol induced tremor is a side effect of using Salbutamol, which is commonly used in the treatment of respiratory conditions.

Emphysema is a chronic lung disease that is caused by damage to the alveoli. This damage leads to air becoming trapped in the alveoli, causing them to expand and rupture. This condition is characterized by difficulty breathing and can be caused by factors such as smoking or long-term exposure to air pollution.

A pneumothorax is an abnormal collection of air in the pleural space between the lung and the chest wall. This condition can cause sudden onset of sharp, one-sided chest pain and shortness of breath.

The correct answer provides a description of the different stages of pneumonia progression. It starts with congestion within the first 24 hours, characterized by vascular engorgement, intra-alveolar fluid, and small numbers of neutrophils. This is followed by red hepatization or consolidation, where vascular congestion persists and red cells extravasate into alveolar spaces, along with increased neutrophils and fibrin. The next stage is grey hepatization, where red cells disintegrate and the alveoli still appear consolidated but with paler color and drier surface. The final stage is resolution, where the exudate is digested by enzymatic activity and cleared by macrophages or cough mechanism.

The correct answer is 5 cm. This is the maximum distance that should be observed between the big thumbs when placing the hands on the chest at the point of the lower ribs and taking a deep breath in and out. The expansion should also be symmetrical.

During inspiration, the muscles between the ribs, known as intercostal muscles, contract and pull inwards. This action helps to expand the chest cavity, allowing for the intake of air into the lungs. The term "pull in" accurately describes this movement of the intercostal muscles during the breathing process. Additionally, accessory muscles, including those in the neck and shoulders, may also be recruited to assist with breathing when there is increased demand or difficulty in breathing.

Bronchiectasis is a disease characterized by the permanent enlargement of parts of the airways in the lungs. This condition leads to typical symptoms such as chronic cough with mucous production. Additionally, individuals with bronchiectasis may experience other symptoms including shortness of breath, coughing up blood, and chest pain.

To properly auscultate and detect abnormal breath sounds, the healthcare provider should ask the patient to take slow, deep breaths. This helps to increase the duration and intensity of the breath sounds, making them more detectable. Additionally, having the patient cough before beginning auscultation helps to clear airway secretions and open small atelectatic areas at the lung bases, improving the quality of the breath sounds. If the patient is unable to sit up, auscultation can be performed while the patient is lying on their side. Requesting the patient to exhale forcibly can also be helpful in accentuating abnormal breath sounds, especially wheezing. If the patient needs to remain supine, a minimal examination can be performed by listening laterally or posteriorly.

The correct answer includes muscles that are commonly used as accessory muscles during breathing. The sternocleidomastoid, scalene, and pectoralis major muscles are all located in the upper chest and neck area and can be recruited to assist with breathing when the primary respiratory muscles are weakened or compromised. The internal intercostal muscles are located between the ribs and are also involved in forced inhalation. The abdominal muscles, specifically the rectus abdominis and external obliques, can be used during forced exhalation. Therefore, checking for the activation or use of these muscles can help determine if a patient is relying on accessory muscles to breathe.

The given answer includes a list of symptoms that can indicate inadequate breathing. These symptoms include a fast or slow rate with an irregular rhythm, abnormal lung sounds, reduced tidal volumes, the use of accessory muscles, and cool, damp, pale, or cyanotic skin. These symptoms are commonly observed in individuals who are not breathing properly, and recognizing these signs can help identify inadequate breathing in a person.

The answer provided correctly identifies the areas of the lungs for percussion. The anterior wall of the upper lobe, posterior wall of the lower lobe, right lateral wall of the middle lobe, and left lateral wall of the lingula are all areas that can be percussed to assess lung sounds and detect any abnormalities.

The given correct answer includes multiple signs and symptoms associated with laboured respiration. Assessing for the use of accessory muscles and retraction of intercostal spaces during inspiration are both indicators of increased effort in breathing. A long expiratory phase of respiration suggests difficulty in exhaling air. Additionally, the use of abdominal muscles to aid in expiration is another compensatory mechanism seen in laboured breathing. Therefore, all of these signs point towards laboured respiration.

The given answer suggests that the possible etiology for accessory muscle use while breathing includes COPD, asthma in exacerbation, secretion retention, and indicates severe respiratory distress and hypoxemia. This means that in conditions such as COPD and asthma exacerbation, the body may use accessory muscles to help with breathing due to the increased difficulty in getting enough oxygen. Secretion retention can also contribute to the need for accessory muscle use. Overall, the presence of accessory muscle use indicates a severe respiratory distress and low oxygen levels in the body.

COPD is a progressive lung disease that is characterized by increasing breathlessness. It is an umbrella term that encompasses various conditions including some forms of Bronchiectasis, Emphysema, Chronic Bronchitis, and Refractory (non-reversible) asthma. This means that individuals with COPD may experience symptoms such as breathlessness due to any of these conditions.

The given answer lists various observations that can be made during a respiratory examination. These observations include assessing whether the person is well or unwell, their level of alertness and consciousness, their body habitus, signs of respiratory distress such as the position of the trachea, tripod position, use of accessory muscles, pursed lips, and flared nostrils. Additionally, the breathing pattern, any added breathing sounds, and whether the cough is dry or productive are also important observations to consider during a respiratory examination.

Whispered pectoriloquy refers to an increased loudness of whispering. Normally, when a patient speaks in a whispered volume, the clinician auscultating the lung field with a stethoscope would not be able to hear the spoken sounds. However, in areas of the lung where there is lung consolidation (fluid or solid mass), the whispered spoken sounds by the patient, such as saying "ninety-nine," will be clearly heard through the stethoscope. This is because sound travels faster and with lower loss of intensity through liquid or solid media compared to gaseous media. Whispered pectoriloquy is a clinical test used to evaluate for the presence of lung consolidation, which could be caused by cancer or pneumonia.

The given answer, "Vesicular Breath Sounds," accurately describes the soft inspiratory sound produced by a healthy individual breathing through their mouth at normal tidal volumes. These breath sounds are characterized by air rushing into the lungs with little noise on expiration.
