Respiratory NCLEX Questions And Answers Graded A+ During an assessment of a 45-year-old patient with asthma, the nurse notes wheezing and dyspnea. The nurse interprets that these symptoms are related to what pathophysiologic change? a. Laryngospasm b. Pulmonary edema c. Narrowing of the airway d. Overdistention of the alveoli Correct Answer C Narrowing of the airway by persistent but variable inflammation leads to reduced airflow, making it difficult for the patient to breathe and producing the characteristic wheezing. Laryngospasm, pulmonary edema, and overdistention of the alveoli do not produce wheezing. A 45-year-old man with asthma is brought to the emergency department by automobile. He is short of breath and appears frightened. During the initial nursing assessment, which clinical manifestation might be present as an early manifestation during an exacerbation of asthma? Anxiety Cyanosis Bradycardia Hypercapnia Correct Answer An early manifestation during an asthma attack is anxiety because the patient is acutely aware of the inability to get sufficient air to breathe. He will be hypoxic early on with decreased PaCO2 and increased pH as he is hyperventilating. If cyanosis occurs, it is a later sign. The pulse and blood pressure will be increased. The nurse is assigned to care for a patient who has anxiety and an exacerbation of asthma. What is the primary reason for the nurse to carefully inspect the chest wall of this patient? Allow time to calm the patient. Observe for signs of diaphoresis. Evaluate the use of intercostal muscles. Monitor the patient for bilateral chest expansion. Correct Answer The nurse physically inspects the chest wall to evaluate the use of intercostal (accessory) muscles, which gives an indication of the degree of respiratory distress experienced by the patient. The other options may also occur, but they are not the primary reason for inspecting the chest wall of this patient. Which position is most appropriate for the nurse to place a patient experiencing an asthma exacerbation? Supine Lithotomy High Fowler's Reverse Trendelenburg Correct Answer The patient experiencing an asthma attack should be placed in high Fowler's position and may need to lean forward to allow for optimal chest expansion and enlist the aid of gravity during inspiration. The supine, lithotomy, and reverse Trendelenburg positions will not facilitation ventilation. The nurse is caring for a patient with an acute exacerbation of asthma. Following initial treatment, what finding indicates to the nurse that the patient's respiratory status is improving? Wheezing becomes louder. Cough remains nonproductive. Vesicular breath sounds decrease. Aerosol bronchodilators stimulate coughing. Correct Answer The primary problem during an exacerbation of asthma is narrowing of the airway and subsequent diminished air exchange. As the airways begin to dilate, wheezing gets louder because of better air exchange. Vesicular breath sounds will increase with improved respiratory status. After a severe asthma exacerbation, the cough may be productive and stringy. Coughing after aerosol bronchodilators may indicate a problem with the inhaler or its use.
