EDGT- Respiratory Questions And Answers Verified 100% Correct When auscultating the lungs of a patient, you hear a low-pitched, grating sound. This is due to A.) partial airway blockage. B.) a pleural friction rub. C.) upper airway obstruction. D.) fluid in the lungs. - ANSWER a pleural friction rub. -Pleural friction rub is a grating, low-pitched sound due to inflammation of the pleura, causing them to rub together. While performing respiratory auscultation, you hear bronchial sounds over the peripheral lung fields. This is A.) a normal finding. B.) indicates an absence of breath sounds. C.) similar to the sound made by pulling apart Velcro. D.) referred to as increased breath sounds. - ANSWER referred to as increased breath sounds. -Vesicular breath sounds are normal over the periphery of the lungs. When bronchial sounds are heard over peripheral lung fields this is referred to as increased breath sounds. Increased breath sounds are due to consolidation, as in pneumonia, or compression causing denser lung tissue that enhances sound transmitted from the bronchi. When inspired air encounters solid lung tissue, sound is conducted more effectively. On respiratory auscultation, you hear a loud, high-pitched, crowing sound that can be heard without a stethoscope. This is A.) crackles. B.) pleural friction rub. C.) ronchi. D.) stridor. - ANSWER stridor. -Stridor are loud, high-pitched sounds that have also been described as "crowing." They can usually be heard without a stethoscope and, since they are caused by an upper airway obstruction, require immediate emergency medical intervention. In respiratory auscultation, tactile fremitus is increased if A.) lung tissue is consolidated. B.) the patient suffers from a pneumothorax. C.) tympanic sounds are heard over the periphery of the lungs. D.) crackles are present. - ANSWER lung tissue is consolidated. -Consolidated lung tissue enhances vibrations and increases tactile fremitus. You are percussing the anterior chest of a patient and reach the area of the border of the liver in the right upper abdominal quadrant. You expect to hear A.) resonance. B.) dullness. C.) flatness. D.) hyperresonance. - ANSWER dullness. -Dullness is a thud-like sound of medium intensity and pitch normally heard over the liver. When performing respiratory auscultation, you would do which of the following? A.) Ask the patient to take shallow breaths. B.) Ask the patient to breathe through his/her mouth. C.) Note that a respiratory rate of 20 is abnormal. D.) Begin auscultation at the bases of the lungs. - ANSWER Ask the patient to breathe through his/her mouth. -The patient should breathe through his/her mouth because breathing through the nose may alter the pitch of the sounds you hear. Abnormal breath sounds described as bubbling or gurgling that occur at the beginning of inhalation are A.) coarse crackles. B.) wheezes. c.) ronchi. D.) stridor. - ANSWER coarse crackles. -Coarse crackles are heard at the beginning of inhalation and are bubbling or gurgling sounds. Diffusion is A.) the distribution of oxygen and carbon dioxide into and out of the pulmonary airways. B.) the movement of oxygen and carbon dioxide through a semipermeable membrane from areas of greater concentration to areas of lower concentration. C.) the blood flow from the heart's right side, through the pulmonary circulation, and enters the left side of the heart. D.) the movement of deoxygenated blood to the left side of the heart via the pulmonary arteries. - ANSWER the movement of oxygen and carbon dioxide through a semipermeable membrane from areas of greater concentration to areas of lower concentration. During assessment, the patient is asked to say the words "blue-moon." You hear the words clearly. This finding A.) is a normal finding. B.) indicates consolidated lung tissue. C.) suggests the possibility of hyperinflated lung tissue. D.) indicates foreign body obstruction of the airways. - ANSWER indicates consolidated lung tissue. - If you clearly hear the words "blue moon", the lung tissue is consolidated. This is referred to as bronchophony. Which of the following assessment findings is NORMAL? A.) resonance over the lung tissue B.) dullness over the lower lobes of the lungs C.) hyperresonance in the upper lobes of the lungs D.) flatness in the right lung - ANSWER resonance over the lung tissue -In the lungs, dullness is due to abnormal lung density, hyperresonance is due to lung hyperinflation, and flatness indicates consolidated lung tissue. The larynx contains which of the following structures? A.) terminal bronchioles B.) alveoli C.) conchae D.) vocal cords - ANSWER vocal cords -The vocal cords are located within the larynx. Which of the following statements concerning respiratory physiology is accurate? A.) The pulmonary arteries carry oxygenated blood to the left side of the heart. B.) Shunting is usually due to an event such as a pulmonary embolism. C.) "Silent unit" is the result of inadequate ventilation and perfusion. D.) Eliminating excessive amounts of carbon dioxide via rapid, deep breathing may lead to respiratory acidosis - ANSWER Shunting is usually due to an event such as a pulmonary embolism. -The pulmonary arteries carry deoxygenated blood. A "silent unit" is the result of airway obstruction. Eliminating excessive amounts of carbon dioxide via rapid, deep breathing may lead to respiratory alkalosis. Lobar bronchi enter the lungs at the
