Chapter 18 : Adrenergic Drugs Questions
Question 1 of 5
The nurse is administering a stat dose of epinephrine. Epinephrine is appropriate for which situation?
Correct Answer: C
Rationale: Treatment of cardiac arrest is an indication for the use of epinephrine. The other options are not indications for epinephrine.
Question 2 of 5
A patient is on a low-dose dobutamine drip for heart failure. She had been feeling better but now has a sense of tightness in her chest, palpitations, and a bit of anxiety. Her heart rate is up to 110 beats/min, and her blood pressure is 150/98 mm Hg (increased from previous readings of 86 beats/min and 120/80 mm Hg). What is the nurse's immediate concern for this patient?
Correct Answer: C
Rationale: Because dobutamine is a vasoactive adrenergic, it works by increasing the cardiac output in heart failure patients by increasing myocardial contractility and stroke volume. However, adrenergic drugs may worsen a preexisting cardiac disorder, such as causing a myocardial infarction in a patient with coronary artery disease. The other options are incorrect.
Question 3 of 5
A 14-year-old patient has been treated for asthma for almost 4 months. Two weeks ago, she was given salmeterol as part of her medication regimen. However, her mother has called the clinic to report that it does not seem to work when her daughter is having an asthma attack. Which response by the nurse is appropriate?
Correct Answer: D
Rationale: Salmeterol is indicated for the prevention of bronchospasms, not treatment of acute symptoms. The dosage is usually two puffs twice daily, 12 hours apart, for maintenance effects in patients older than 12 years of age. The other options are incorrect.
Question 4 of 5
A hospitalized patient is experiencing a severe anaphylactic reaction to a dose of intravenous penicillin. Which drug will the nurse expect to use to treat this condition?
Correct Answer: B
Rationale: Epinephrine is the drug of choice for the treatment of anaphylaxis. The other drugs listed are incorrect choices.
Question 5 of 5
The nurse recognizes that adrenergic drugs cause relaxation of the bronchi and bronchodilation by stimulating which type of receptors?
Correct Answer: C
Rationale: Stimulation of beta2 adrenergic receptors results in bronchodilation. The other choices are incorrect.
