Exam 3 Review: Goldstein Flashcards

1
Q

What is the difference between a patient who only needs a SABA PRN and someone that will get a daily asthma medication?
(What would make someone get a daily asthma medication instead of a SABA PRN?)

A

When they use their inhaler too much

o Inhaler is a rescue medication and shouldn’t be used all day/everyday (too much) so they will need to be on daily medication

Q

three things to monitor to assess for adverse effects of albuterol?
(SE/AE: Tachycardia, Hypokalemia, Hyperglycemia)

A

o potassium
o glucose

Q

why does albuterol cause tachycardia?

A

because were activating beta 2 but beta 1 also gets affected

o Beta 1 activates your whole fight or flight response – get high heart rate/BP – when body is super stressed it releases sugar because your body needs energy for the flight or flight

  • (reason for AE/SE) Because of the release of sugars it causes hyperglycemia then the body releases insulin to get it under control – and the insulin and glucose into the cell and take potassium with them which causes potassium to go down

a patient is receiving albuterol for a severe asthma attack, the patient becomes tachycardic and with a heart rate of 155 and complaining of palpations, what would be an appropriate nursing intervention?
