Stem
A 58-year-old patient is scheduled for a lipid panel and reports
having eaten breakfast 45 minutes earlier. The phlebotomy
technician informs you the lab will still accept the specimen.
What is your best nursing action before the blood draw?
A. Proceed with the draw; the lab will note “nonfasting” and
interpret accordingly.
B. Ask the patient to skip the test; reschedule for a fasting
,specimen tomorrow.
C. Document the recent meal and proceed, and notify the
provider that results may be affected.
D. Offer the patient a light snack to standardize the testing
conditions.
Correct answer
C
Rationales
• Correct (C): Chapter 1 emphasizes pretest responsibilities
including documenting deviations from preparation and
communicating potential impacts on interpretation;
proceeding with documentation and provider notification
preserves data and patient flow.
• A: Incorrect — although labs may flag “nonfasting,” simply
relying on the lab without documenting and notifying the
provider risks misinterpretation and inappropriate clinical
decisions.
• B: Incorrect — automatically canceling/rescheduling is
unnecessary if clinical urgency is low; documentation plus
provider notification is preferred.
• D: Incorrect — giving a snack alters results further and
violates test preparation; it does not standardize
conditions.
,Teaching Point
Document and notify provider when pretest preparation is not
met; avoid introducing new variables.

Stem
A urinalysis requisition indicates “random urine” but the patient
asks whether midstream (“clean-catch”) is required. Which
statement best reflects the nurse’s responsibility per Chapter 1?
A. Collect the first-void specimen because it concentrates cells
and is more sensitive.
B. Follow the test’s collection instructions; provide patient
teaching on midstream technique if required.
C. Substitute with a catheterized specimen to ensure sterility
and avoid patient instructions.
D. Collect any specimen and rely on the lab to correct for
contamination.
Correct answer
B
, Rationales
• Correct (B): Chapter 1 highlights the importance of correct
specimen type and patient education for accurate results;
nurses must follow collection instructions and teach
technique when needed.
• A: Incorrect — first-void is sometimes used, but midstream
is specified for culture to reduce contamination; selecting
first-void without instruction may invalidate results.
• C: Incorrect — catheterization has risks and is not an
appropriate substitution unless specifically ordered.
• D: Incorrect — the lab cannot reliably “correct”
contaminated specimens; prevention at collection is
essential.
Teaching Point
Match specimen type to test; teach and supervise collection to
avoid contamination.
