NURS 6521N Week 4 Quiz 3.Q&A • Question 1 1 out of 1 points A high school student was diagnosed with asthma when he was in elementary school and has become accustomed to carrying and using his “puffers”. In recent months, he has become more involved in sports and has developed a habit of administering albuterol up to 10 times daily. The nurse should teach the student that overuse of albuterol can lead to Response Feedback: Patients who self-administer albuterol may use their MDIs more frequently than recommended. This practice can result in rebound bronchoconstriction, which may motivate the patient to increase MDI use, stimulating the cycle of rebound congestion. Overuse of albuterol is not linked to pneumonia or hepatotoxicity. Albuterol is not an anticholinergic drug. • Question 2 1 out of 1 points A nurse is caring for a female patient who has developed atelectasis because of thick mucus secretions. The nurse is monitoring IV administration of acetylcysteine (Mucomyst) and notices that the patient's face is flushed. The appropriate nursing action would be to Response Feedback: A frequent adverse reaction to IV acetylcysteine is facial flushing. If this occurs, the nurse should slow the IV infusion and administer diphenhydramine, which is an antihistamine ordered by the physician whenever acetylcysteine is ordered. A patient receiving IV acetylcysteine should also be monitored for anaphylactic reaction, which is indicated by tightness in the chest, rash, hypotension, and tachycardia. If any of these signs occurs, the nurse should immediately stop the infusion. Removing residual drug from the face would not be an option, since the medication is delivered via the IV route and is not a drug that can be applied topically. Diluting acetylcysteine would not serve to minimize this adverse effect. • Question 3 1 out of 1 points Children age 6 to 11 are recommended to start with what dosage of Allegra? • Question 4 1 out of 1 points A man who smokes one pack of cigarettes daily has been diagnosed with chronic bronchitis. He has been prescribed theophylline by his family doctor. What effect will the patient's smoking status have on the therapeutic use of theophylline? Response Feedback: Smoking cigarettes may decrease serum theophylline levels. In fact, some patients who smoke require an increase in theophylline dosage of up to 50%. Theophylline is not associated with a risk of anaphylactoid reaction. Theophylline doses do not need to be concurrent with the use of bronchodilators. • Question 5 1 out of 1 points A 25-year-old woman comes to the clinic because of a chronic, nonproductive cough. Assessment reveals that she has a history of asthma and dextromethorphan, (Robitussin) is prescribed for her. The nurse will question this order because Response Feedback: Dextromethorphan is contraindicated in patients with asthma. If coughing were to be suppressed, these patients may retain secretions, and this would exacerbate the disease. Dextromethorphan does not result in persistent coughing or thickening of respiratory secretions. The drug may lead to serotonin syndrome if used with MAOIs. .........CONTINUED
