Chapter 20, Problem 28RQ
Hannah, a 31-year-old woman, decided to have colonic irrigation, a procedure during which large volumes of distilled water were infused into her rectum. During the treatment, she absorbed 3000 mL of water. About 12 hours later, her roommate found her in convulsions and took her to the emergency room. Her blood pressure was 140/90, her plasma Na+ concentration was 106 mEq/L (normal: 135 mEq/L), and her plasma osmolarity was 270 mOsM. In a concept map or flowchart, diagram all the homeostatic responses her body was using to attempt compensation for the changes in blood pressure and osmolarity.

A 44-year-old woman was experiencing headaches and fatigue. The consultingphysician recommended testing glucose and electrolytes. The results are attached in the picture below:
(a) What is the difference between serum and plasma? (b) Describe the results (c) Plasma glucose levels lower than 20 mg/dl can be fatal. As the patient’s resultsdid not match with her clinical presentation, the consulting biochemist decidedto investigate this test, and found that the glucose analyser was giving theresults in mM, but the lab assistant had assumed the results were in mg/dl. Isthis error pre-analytical, analytical or post-analytical? (d) 1 mM glucose = 18 mg/dL glucose. What is the patient’s fasting plasmaglucose in mg/dL, and is it within the normal range? (e) Describe possible consequences of this error.
