A provider orders an ESR to be performed on a patient and describes the test to the patient. Which of the following statements made by the patient indicates an understanding of the teaching?
"This test measures my estrogen serum ratio after menopause."
"This test measures the fluctuation of serum protein."
"This test measures my hemoglobin levels."
"This test measures the distance my RBCs have dropped."
The Correct Answer is D
A. "This test measures my estrogen serum ratio after menopause." ESR stands for erythrocyte sedimentation rate, not estrogen serum ratio. This is an incorrect interpretation of the test.
B. "This test measures the fluctuation of serum protein." The ESR does not directly measure serum protein levels. It measures the rate at which red blood cells sediment in a period of one hour.
C. "This test measures my hemoglobin levels." Hemoglobin levels are measured by a hemoglobin test, not an ESR. This statement is incorrect.
D. "This test measures the distance my RBCs have dropped." This is the correct understanding. ESR measures the rate at which red blood cells settle at the bottom of a test tube over a specified period, indicating the distance the RBCs have dropped.

Correct Answer is A
Explanation
A. Reaching over the field: Reaching over a sterile field can contaminate it by introducing microorganisms from outside the sterile area.
B. Maintaining a 1-inch border around the edge of the sterile field: Maintaining a 1-inch border is a standard practice to ensure that the edges of the sterile field are not contaminated.
C. Holding all sterile articles at waist level: Holding sterile articles above the waist level is the recommended practice to prevent contamination. Holding them at waist level is considered acceptable as long as the items do not touch non-sterile surfaces.
D. Facing the sterile field: Facing the sterile field while working is part of maintaining sterile technique, as it ensures that you do not accidentally move toward the sterile field and contaminate it.
Correct Answer is B
Explanation
A. Lysosomes: Lysosomes contain digestive enzymes that break down waste materials and cellular debris but are not responsible for energy production.
B. Mitochondria: Mitochondria are known as the "powerhouses" of the cell because they produce energy through cellular respiration.
C. Nucleolus: The nucleolus is involved in producing ribosomes and RNA synthesis, not energy production.
D. Microvilli: Microvilli increase the surface area of cells for absorption but do not produce energy.
