CHAPTER 1: Overview of Laboratory and Diagnostic Testing
Multiple Choice Questions
1. The nurse understands that the primary purpose of laboratory and diagnostic testing is to:
a) Replace the physical assessment
b) Provide objective data to assist in the diagnosis and management of patient conditions
c) Confirm the physician's initial impression in all cases
d) Eliminate the need for patient history taking
Answer: B
Rationale: Laboratory and diagnostic testing provides objective, measurable data that assists healthcare
providers in diagnosing, managing, and monitoring patient conditions. It supplements but does not
replace the history and physical examination.
2. Which of the following best describes a "critical value" in laboratory testing?
a) Any abnormal result that falls outside the reference range
b) A result that indicates a life-threatening condition requiring immediate notification
c) A value that is slightly elevated above normal limits
d) A result that requires repeat testing for confirmation
Answer: B
Rationale: Critical values (also called panic values) are results that indicate a potentially life-threatening
situation and require immediate notification of the healthcare provider so that prompt treatment can
be initiated.
3. When interpreting laboratory results, the nurse should consider:
