91
Q

Auscultation, how breathing, accessory muscles to breathe - resp assessments
Cardiac
Lung sounds, RR, heart sounds, HR, oxygen saturation, work of breathing, skin color (cyanosis)

A

A medical-surgical nurse is caring for a client with a history of asthma. The client turns on the call light and states to the nurse “I’m feeling short of breath, and I need my inhaler!”
Prescribed inhalers: salmeterol, albuterol, fluticasone
What assessments should the nurse perform?

92
Q

Monitor them for further decline
Asthma attack, respiratory compromise, potential for respiratory distress and declining oxygen saturation

A

What is the problem?

93
Q

Albuterol

A

What medication should the nurse administer?

94
Q

Increase oxygen saturation to > 92%, decrease RR to normal limits, decrease work of breathing

A

The nurses asks the unlicensed assistant personnel (UAP) to obtain a set of vitals while obtaining the medication.
VS: HR 102; RR 26; BP 128/70; O2 sat 87%
What is the expected outcome / short term goal for this client?

95
Q

Second dose of albuterol; apply O2 - typ have standing order in-pat to keep >92% and if do not, call provider to get order
Administer albuterol, apply oxygen, place client in upright position, keep calm and not exacerbate what going on

A

What interventions should the nurse perform?

96
Q

eval piece
Evaluate the client: assess vital signs; heart and lung assessment; client statements
Reassess pat - looking at VS making sure went way wanted to go; monitor HR so not go up too much after admin of albuterol - might have impact on HR and not - why get VS and listen to heart and lung sounds if note any probs or abnormalities; elevated - already distressed

A

How will the nurse know the desired outcome has been achieved?

97
Q

Remember to

A

document interventions and evaluation did! - Doc gave med, on O2 - make sure doc reassessment and what found
