The nurse caring for a patient who is receiving beta1 agonist drug therapy needs to be aware that these drugs
cause which effect?
a Increased cardiac contractility
b Decreased heart rate
c Bronchoconstriction
d Increased GI tract motility - ANSWERa Increased cardiac contractility
During a teaching session for a patient who is receiving inhaled salmeterol, the nurse emphasizes that the drug
is indicated for which condition?
,a Rescue treatment of acute bronchospasms
b Prevention of bronchospasms
c Reduction of airway inflammation
d Long-term treatment of sinus congestion - ANSWERb Prevention of bronchospasms
For a patient receiving a vasoactive drug such as intravenous dopamine, which action by the nurse is most
appropriate?
a Monitor the gravity drip infusion closely, and adjust as needed.
b Assess the patient's cardiac function by checking the radial pulse.
c Assess the intravenous site hourly for possible infiltration.
d Administer the drug by intravenous boluses according to the patient's blood pressure - ANSWERc Assess the
intravenous site hourly for possible infiltration
A patient is receiving dobutamine for shock and is complaining of feeling more "skipping beats" than
yesterday. What will the nurse do next?
a Monitor for other signs of a therapeutic response to the drug.
b Titrate the drug to a higher dose to reduce the palpitations.
c Discontinue the dobutamine immediately.
d Assess the patient's vital signs and cardiac rhythm - ANSWERd Assess the patient's vital signs and cardiac
rhythm
When a drug is characterized as having a negative chronotropic effect, the nurse knows to expect which
effect?
a Reduced blood pressure
b Decreased heart rate
c Decreased ectopic beats
d Increased force of cardiac contractions - ANSWERb Decreased heart rate
The nurse is monitoring a patient who is receiving an infusion of a beta-adrenergic agonist. Which adverse
effects may occur with this infusion? (Select all that apply.)
, a Mild tremors
b Bradycardia
c Tachycardia
d Palpitations
e Drowsiness

The order reads: "Dopamine 3 mcg/kg/min IV." The solution available is 400 mg in 250 mL D5W, and the
patient weighs 176 pounds. The nurse will set the IV infusion pump to run at how many mL/hour? - ANSWER9
mL/hr
Mydriasis - ANSWERpupillary dilation
positive chronotropic effect - ANSWERincrease heart rate
positive domotropic effect - ANSWERincrease in the conduction of cardiac electrical impulses through the AV
node
leads to systolic heart beat
positive inotropic effect - ANSWERincrease in the force of contraction of the heart muscle
A client received epinephrine for an anaphylactic reaction in the emergency department 6 hours ago. Since
