Case StudyA 60-year-old professor who has a colon resection for an interstinal tumor is receiving incentive spirometry to help expand his lungs.  You are asked to assess the patient for retained secretions.  Auscultation reveals coarse rhonchi bilaterally in the upper lobes.  A few scattered crackes are heard in the bases.  SpO2 on room air is 94%.  The patient states he is unable to cough up anything “because it hurst too much.”1.  What technique could you use to decrease the pain associated with cough in a postoperative patient?2.  What type of cough would you teach this patient?

The Langmuir adsorption isotherm is derived based on the assumption that:

A metal surface has an adsorption site density of 10−6 mol/m². The Langmuir constant is K=5 L/mol. At a concentration of C=0.2 M, how many moles of adsorbate are present per square meter?

A Doctor ask for your recommendation for a 55-year-old 125-lb woman who has increase work of breathing and aleteclesis.. In evaluating this patient at the bedside, you obtain a VC of 800 ml and an IC of 50% predicted. Although a chest radiograph indicates basal atelectasis, she has no problem with retained secretions. What lung expansion treatment would you recommend?

List two conditions that may cause internal obstuction or external compresssion of the airway lumen.

Which of the following patient groups should be considered for lung expansion therapy using intermittent positive-pressure breathing (IPPB)?1.
