D)pseudoephedrine

Question 6

A female patient is on a low-dose dobutamine drip for heart failure.She had been feeling "better" but now reports tightness in her chest and a bit of anxiety.Her heart rate,which was 86,is now up to 110,and her blood pressure,which was 120/80,is now 150/98.What is the nurse's immediate assessment of the patient's condition?

Question 10

A 14-year-old female patient has been treated for asthma for almost 4 months.Two weeks ago,she was given salmeterol xinafoate 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 experiencing acute symptoms.What does the nurse think in response to the mother's concerns?
