D.Z., a 68-year-old man, is admitted at 1600 to a medical floor with a diagnosis of acute exacerbation of chronic obstructive pulmonary disease (COPD). His other past medical history includes hypertension, atrial fibrillation, and sleep apnea. He has had pneumonia yearly for the past 3 years and has been a two-pack-a-day smoker for 38 years. His current medications include enalapril (Vasotec), hydrochlorothiazide (HCTZ), rivaroxaban (Xarelto) and fluticasone/salmeterol (Advair). He appears a cachectic man who is experiencing difficulty breathing at rest. D.Z. seems irritable and anxious; he complains of sleeping poorly and states that lately he feels tired most of the time. You auscultate decreased breath sounds, expiratory wheezes, and coarse crackles in both lower lobes anteriorly and posteriorly. 

 

His vital signs (VS) are 155/84, HR 110, T 37.4C, RR 30, and Spo2 88%.

 

Assessment findings this morning:

Increased fatigue over the past 3 days
Alert and oriented X 2-disoriented to place this morning 
Tripod position
Dyspnea
Fatigue
Accessory muscle use
Breath sounds diminished to bases bilaterally 
Productive cough with yellow blood-tinges sputum—difficulty expectorating 
Expiratory wheeze bilaterally
Barrel chest 
Skin is pale, hot and dry 
Strong peripheral pulses 
Intermittent chills 
Fingernails are yellow with clubbing present

 

 

Explain the pathophysiology and significance of the target O2 saturation of 88-92% in a patient with COPD. (4 marks).

 

You assess your patient and get the following Vital Signs. Explain the rationale for each of the VS findings below. Indicate whether they are normal or abnormal, indicate normal ranges, and explain your rationale for the change in VS. 1 mark for normal ranges and indication of normal/abnormal VS, 1 mark for explanation. (10 marks) 

 

T 37.4 C HR 110/bpm
BP 155/84 O2 sat 88%
RR 30/min
