Question
Chapter 7, Problem 1SRQ
Summary Introduction
Introduction: Glycolysis is a cellular process in which glucose molecules are broken down to form pyruvate. An antiglycolytic agent is defined as a substance that inhibits glycolysis by blood cells.
Expert Solution & Answer
Answer to Problem 1SRQ
Correct answer: “Sodium fluoride prevents glycolysis”. Therefore, option d. is correct.
Explanation of Solution
Reason for the correct answer:
Option d. is given as “Sodium fluoride”.
Sodium fluoride is an inorganic salt of fluoride and is the most common antiglycolytic agent that preserves glucose in the blood and prevents glycolysis. It can clot the blood by itself, but more commonly used with the ethylenediaminetetraacetic acid (EDTA) or anticoagulant potassium oxalate to provide plasma specimens.
Hence, option d. is correct.
Reasons for the incorrect answers:
Option a. is given as “EDTA”.
EDTA is not an antiglycolytic agent, it is an anticoagulant agent. Therefore, option a. in incorrect.
Option b. is given as “Heparin”.
Heparin is not an antiglycolytic agent, it is an anticoagulant agent. Therefore, option b. is incorrect.
Option c. is given as “Potassium oxalate”.
Potassium oxalate is not an antiglycolytic agent, it is an anticoagulant agent. Therefore, option c. is incorrect.
Hence, options a., b., and c. are incorrect.
Conclusion
Sodium fluoride prevents glycolysis.

At his first treatment, the nurse hooks up the bloodlines to an access in David's chest. He tells her that he had surgery on his arm three months ago so it can be used for dialysis eventually. 1. What type of access does David have for the initial treatment? 2. Is David's arm access most likely a graft or fistula? 3. What possible reasons prevent use of a fistula or graft for the first dialysis treatment? Case 2 Ramon, a hemodialysis patient for six years, has lost 1.5 kg over the past six weeks. He denies nausea or vomiting, but does admit to eating less at meals and skipping dinner some days. Current dialysis prescription is: 3 1/2 hours (210 minutes), 3 times a week, ASAHI 1050S, APS dialyzer, dialysis flow rate 800 ml/min, blood flow rate 400 ml/min.

Urea Reduction Ratio is a more accurate measurement of dialysis adequacy than Urea Kinetic Modeling. A fistula is the preferred type of vascular access. In the formula Kt/V, the V represents volume of total body water in which urea is distributed. In the formula Kt/V, time is measured in 15-minute increments, so 220 minutes would be rounded off to the nearest quarter hour. The DaVita minimum goal for adequacy is a spKt/V≥ 1.0. A measured height and accurate dry weight are required to obtain an accurate Kt/V result. A very low post BUN result usually means the patient is not eating enough protein. KRU is a measure of residual urea clearance by the patient's kidney, requiring a 24-hour urine collection. The Kt/V Delivered (single pool) is the value used for determining adequacy and comparing outcomes in DaVita facilities. Catheters are…arrow_forward
