Answer to Question 1

ANS: B
A three-point calibration should be performed every 6 months or whenever an electrode is re-placed. A two-point calibration is usually performed at least three times daily, typically every 8 hours. In many cases, analyzers can be programmed to perform a two-point calibration at prede-termined intervals. The one-point calibration involves adjusting the electronic output to a single, known standard and should be performed before an unknown sample is analyzed, unless the an-alyzer is programmed to perform a one-point calibration automatically at regular intervals, such as every 20 to 30 minutes. Quality control is the system that includes the analysis of control samples and assessment of the measurements against defined limits, identification of problems, and spec-ification of corrective actions.

Answer to Question 2

ANS: B
The sensors used for electrolyte measurements are ion-selective electrodes. A Clark electrode is used to measure the partial pressure of oxygen in the blood. A polarographic electrode is a Clark electrode. Glucose-oxidase is an enzyme that is used to coat the ion-selective electrode used to measure glucose.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
