Normal Levels of Substances in the Arterial Blood: pH 7.40 + 0.05 pCO2 (partial pressure of carbon dioxide) 40 mm Hg pO2 (partial pressure of oxygen) 90 - 100 mm Hg Hemoglobin - O2 saturation 94 - 100 % [HCO3-] 24 meq / liter Vignette #1: A 21-year-old noncompliant female with a history of type I (insulin-dependent) diabetes mellitus was found in a coma. Her blood glucose was high, as well as her urine glucose, urine ketones, and serum ketones. Her serum bicarbonate was < 12 mEq/L. Her respiration was exaggerated, and her breath had an acetone odor. Her blood pressure was 90/60 and his pulse weak and rapid (120). 4. What is the acid-base status of this individual? 5. What are the causes of the dyspnea, hypotension, and tachycardia? 6.

Measuring Height, Weight, and Vital Signs The nurse asks you to obtain a complete set of vital signs for an adult client to whom you are assigned. The measurements are as follows: temperature 38.6°C (101.5°F), heart rate 104 beats/min, respiratory rate 22 breaths/min, and blood pressure 90/60 mm Hg. Which of these vital signs are of concern? What is your first action after collecting these vital signs?
Dave is a 41-year-old male who was referred by his primary care physician after presenting to the ER with difficulty breathing. Dave’s physician was unable to find a medical explanation for his symptoms, which left Dave feeling confused, stressed, and angry. Over the last 6 months, Dave has had several instances where he felt an intense fear that would reach a peak within a few minutes. During these instances, he would also experience sweating, heart palpitations, chest pain and discomfort, and shortness of breath. At times, Dave worried that might die. As a result, Dave has persistent worry about having another attack. In addition, he has begun to avoid unfamiliar places and people where it may be difficult to get help in the event of another panic attack. The panic and associated avoidance are significantly impacting Dave’s life as he has been turning down social invitations, making excuses to stay at home whenever possible, and relying on his wife to drive their children to their…
