Chapter 37 : Respiratory Drugs Questions
Question 1 of 5
A patient has a metered-dose inhaler that contains 200 actuations ('puffs'), and it does not have a dose counter. He is to take two puffs two times a day. If he does not take any extra doses, identify how many days will this inhaler last at the prescribed dose.
Correct Answer: 50 days
Rationale: Assuming that two puffs are taken two times a day, and the inhaler has a capacity of 200 inhalations. Two puffs two times a day equal four inhalations per day. Four divided into 200 yields 50, that is, the inhaler will last approximately 50 days.
Question 2 of 5
A patient will be receiving oral theophylline, 600 mg/day, in three divided doses. Identify how many milligrams the patient will receive per dose.
Correct Answer: 200 mg
Rationale: 600 mg/day divided by 3 doses per day = 200 mg/dose.
Question 3 of 5
A patient is taking intravenous aminophylline for a severe exacerbation of chronic obstructive pulmonary disease. The nurse will assess for which therapeutic response?
Correct Answer: D
Rationale: The therapeutic effects of bronchodilating drugs such as xanthine derivatives include increased ease of breathing. The other responses are incorrect.
Question 4 of 5
A patient is taking a xanthine derivative as part of treatment for chronic obstructive pulmonary disease. The nurse will monitor for which adverse effects associated with the use of xanthine derivatives?
Correct Answer: B
Rationale: The common adverse effects of the xanthine derivatives include nausea, vomiting, and anorexia. In addition, gastroesophageal reflux has been observed to occur during sleep in patients taking these drugs. Cardiac adverse effects include sinus tachycardia, extrasystole, palpitations, and ventricular dysrhythmias. Transient increased urination and hyperglycemia are other possible adverse effects.
Question 5 of 5
A patient is in an urgent care center with an acute asthma attack. The nurse expects that which medication will be used for initial treatment?
Correct Answer: B
Rationale: The short-acting beta agonists are commonly used during the acute phase of an asthmatic attack to reduce airway constriction quickly and to restore airflow to normal levels. The other drugs listed are not appropriate for acute asthma attacks. Anticholinergic drugs and long-acting beta agonists are used to prevent attacks; corticosteroids are used to reduce airway inflammation.
