Question

a nurse is assisting in the care of a client who has status asthmaticus. which of the following is an indication that the client is responding to treatment?
manifestations resolve for 30 minutes after the last bronchodilator dose and pefr is greater than 70%
manifestations resolve for 5 minutes after the last bronchodilator dose and pefr greater than 50%
the oxygen saturation has improved to 86%.
maximal inspiratory pressure (mip) of 120 cm h2o

Explanation:

Step1: Analyze each option

• For the first option: Manifestations resolving for 30 minutes after the last bronchodilator dose and PEFR (Peak Expiratory Flow Rate) being greater than 70% indicates improvement. Bronchodilators work to open airways, and a sustained improvement (30 minutes) along with a good PEFR (which measures how fast one can blow air out and values >70% of personal best or predicted are better in asthma management) is a sign of response to treatment.
• Second option: Manifestations resolving for only 5 minutes is too short - term and not a good sign of a proper response. Also, a PEFR >50% is not as indicative of a good response as >70%.
• Third option: An oxygen saturation of 86% is still low (normal is usually 95 - 100% in healthy individuals, and in asthma, we aim for higher values like 92 - 95% or more).
• Fourth option: Maximal inspiratory pressure (MIP) of 120 cm H2O. Normal MIP values are more negative (e.g., - 80 to - 120 cm H2O in healthy people, but in asthma, we are more focused on airway - related improvements like bronchodilation effects rather than just MIP in this context of response to asthma treatment).

Answer:

Manifestations resolve for 30 minutes after the last bronchodilator dose and PEFR is greater than 70%
