Which medication classification is generally included in the treatment of silicosis? Student Answer: CORRECT Corticosteroids Antibiotics Bronchodilators Expectorants Instructor Explanation: No... specific treatment exists for silicosis, although corticosteroids may produce some improvement in the early, more acute stages. The other options are not generally prescribed. Points Received: 0.5 of 0.5 Comments: Question 2. Question : Which immunoglobulin is present in childhood asthma? Student Answer: Immunoglobulin M (IgM) Immunoglobulin G (IgG) CORRECT Immunoglobulin E (IgE) Immunoglobulin A (IgA) Instructor Explanation: Included in the long list of asthma-associated genes are those that code for increased levels of immune and inflammatory mediators (e.g., interleukin [IL]–4, IgE, leukotrienes), nitric oxide, and transmembrane proteins in the endoplasmic reticulum. None of the other options are associated with childhood asthma. Points Received: 0.5 of 0.5 Comments: Question 3. Question : Sitting up in a forward-leaning position generally relieves which breathing disorder? Student Answer: Hyperpnea This study source was downloaded by 100000831988016 from CourseHero.com on 04-22-2022 14:21:40 GMT -05:00 https://www.coursehero.com/file/25459080/week-5-quizdocx/ CORRECT Orthopnea Apnea Dyspnea on exertion Instructor Explanation: Of the options available, only orthopnea is generally relieved by sitting up in a forward-leaning posture or supporting the upper body on several pillows. Points Received: 0.5 of 0.5 Comments: Question 4. Question : How does chest wall compliance in an infant differ from that in an adult? Student Answer: CORRECT An adult’s chest wall compliance is lower than an infant’s. INCORRECT An adult’s chest wall compliance is higher than an infant’s. An adult’s chest wall compliance is the same as an infant’s. An adult’s chest wall compliance is dissimilar to that of an infant’s. Instructor Explanation: Chest wall compliance is higher in infants than it is in adults, particularly in premature infants. Points Received: 0 of 0.5 Comments: Question 5. Question : Which pulmonary defense mechanism propels a mucous blanket that entraps particles moving toward the oropharynx? Student Answer: Nasal turbinates Alveolar macrophages CORRECT Cilia Irritant receptors on the nares Instructor Explanation: The submucosal glands of the bronchial lining produce mucus, contributing to the mucous blanket that covers the bronchial epithelium. The ciliated epithelial cells This study source was downloaded by 100000831988016 from CourseHero.com on 04-22-2022 14:21:40 GMT -05:00 https://www.coursehero.com/file/25459080/week-5-quizdocx/ rhythmically beat this mucous blanket toward the trachea and pharynx, where it can be swallowed or expectorated by coughing. This selection is the only option that accurately identifies the pulmonary defense mechanism described. Points Received: 0.5 of 0.5 Comments: Question 6. Question : If a patient develops acidosis, the nurse would expect the oxyhemoglobin dissociation curve to react in which manner? Student Answer: CORRECT Shift to the right, causing more oxygen (O2) to be released to the cells Shift to the left, allowing less oxygen (O2) to be released to the cells Show no change, allowing the oxygen (O2) concentration to remain stable Show dramatic fluctuation, allowing the oxygen (O2) concentration to increase Instructor Explanation: A shift to the right depicts hemoglobin’s decreased affinity for O2 or an increase in the ease with which oxyhemoglobin dissociates and O2 moves into the cells. The oxyhemoglobin dissociation curve is shifted to the right by acidosis (low pH) and hypercapnia (increased partial pressure of arterial carbon dioxide [PaCO2]). This selection is the only option that accurately identifies what will happen to the oxyhemoglobin dissociation curve if acidosis occurs. Points Received: 0.5 of 0.5 Comments: Question 7. Question : Which pleural abnormality involves a site of pleural rupture that acts as a one-way valve, permitting air to enter on inspiration but preventing its escape by closing during expiration? Student Answer: Spontaneous pneumothorax CORRECT Tension pneumothorax Open pneumothorax Secondary pneumothorax This study source was downloaded by 100000831988016 from CourseHero.com on 04-22-2022 14:21:40 GMT -05:00 https://www.coursehero.com/file/25459080/week-5-quizdocx/ Instructor Explanation: In tension pneumothorax, the site of pleural rupture acts as a one-way valve, permitting air to enter on inspiration but preventing its escape by closing up during expiration. As more and more air enters the pleural space, air pressure in the pneumothorax begins to exceed barometric pressure. None of the other options result from the pathologic condition described. Points Received: 0.5 of 0.5 Comments: Question 8. Question : Clinical manifestations of decreased exercise tolerance, wheezing, shortness of breath, and productive cough are indicative of which respiratory disorder? Student Answer: CORRECT Chronic bronchitis Emphysema Pneumonia INCORRECT Asthma Instructor Explanation: The symptoms that lead individuals with chronic bronchitis to seek medical care include decreased exercise tolerance, wheezing, and shortness of breath. Individuals usually have a productive cough (“smoker’s cough”). The described symptoms are not associated with any of the other options. Points Received: 0 of 0.5 Comments: Question 9. Question : How is most carbon dioxide (CO2) in the blood transported? Student Answer: Attached to oxygen (O2) CORRECT In the form of bicarbonate Combined with albumin INCORRECT Dissolved in the plasma Instructor Explanation: Approximately 60% of the CO2 in venous blood and 90% of the CO2 in arterial blood are carried in the form of bicarbonate.
