Which of the following instructions should a medical assistant give a patient who needs to collect a clean catch midstream urine specimen?
"Clean the perineal area from back to front."
"Void a small amount into the toilet before voiding into the cup."
"Urinate directly into the container with preservative."
"Collect all urine from start to finish."
The Correct Answer is B
A. "Clean the perineal area from back to front.": For females, cleaning should be done from front to back to avoid contamination from fecal matter. For males, cleaning should be done around the urethral opening.
B. "Void a small amount into the toilet before voiding into the cup.": This helps to flush out any contaminants from the urethra, ensuring that the urine collected in the cup is as clean as possible.
C. "Urinate directly into the container with preservative.": Urinating directly into a container with preservative can contaminate the sample and is not recommended for a clean catch specimen.
D. "Collect all urine from start to finish.": The clean catch method specifically involves discarding the initial stream of urine and collecting the midstream to avoid contaminants.

Correct Answer is A
Explanation
A. Wrapping hinged instruments in the open, unlocked position: Hinged instruments should be wrapped in the open, unlocked position to ensure that steam can penetrate all surfaces for effective sterilization.
B. Allowing the temperature of the autoclave to reach 200° F before timing: The autoclave should reach the required temperature (typically 250°F or 121°C) for the appropriate amount of time for sterilization, not 200°F.
C. Using a ballpoint pen to label contents: It is not advisable to use a ballpoint pen for labeling sterilized items because ink might not withstand the autoclave's high temperatures. Permanent markers or labels that can endure high temperatures should be used.
D. Stacking wrapped packages tightly into the autoclave: Items should be arranged in a way that allows steam to circulate freely, so tightly stacking packages can hinder proper sterilization.
Correct Answer is B
Explanation
A. Sweating: Sweating is a normal physiological response to exercise and is not an indication to terminate the test.
B. Bradycardia: Bradycardia (abnormally slow heart rate) during an exercise stress test can indicate a serious problem and may require premature termination of the test.
C. Palpitations: Palpitations can occur during exercise, but they are not necessarily a reason to terminate the test unless accompanied by other symptoms or abnormalities.
D. Thirst: Thirst is not a contraindication for continuing an exercise stress test.
