Anemia

Deborah Murray is 6 months pregnant, and Dr. Diapedesis wants Latisha Sharpe, CMA (AAMA), to check her hemoglobin level. Dr. Diapedesis has ordered this test because pregnant women are at increased risk for

Gently blowing on the slides to dry them

Dr. Diapedesis orders a CBC with differential cell count on Chad Cron. After collecting a lavender tube, Latisha prepares the blood smears. Which of the following techniques would Latisha not use in preparing the smears?

Low

Latisha Sharpe, CMA (AAMA), determines Richard's hematocrit value to be 37. This value is considered

Shaking the tube three to four times to mix the blood with the anticoagulant

Latisha Sharpe, CMA (AAMA), is getting ready to draw a blood specimen for a PT/INR test from Daniel Stockton, who is on long-term warfarin therapy. The sample will be analyzed at an outside laboratory. Latisha performs all of the following except

Normal

Latisha collects a capillary blood specimen from Deborah and runs a hemoglobin test. The hemoglobin value is 14, which is considered

At the top of the red blood cell column

Latisha fills two capillary tubes and centrifuges them in the microhematocrit centrifuge. After the centrifuge comes to a complete stop, Latisha reads the results

A slide that has a rounded, thick edge at the end of the smear

Latisha has prepared the blood smears and looks at them to make sure they have been prepared correctly. Which of the following slides would not be considered suitable for a blood smear?

The tip of the capillary tube is pressed against Richard's finger

Richard Wrighter comes in for a general physical examination. As part of his examination, Dr. Diapedesis asks Latisha Sharpe, CMA (AAMA), to perform a hematocrit. Latisha performs a finger puncture. After inserting the tip of the capillary tube into the drop of blood, Latisha discovers that no blood is entering the tube. What is the most likely cause of this?

White blood cell count: 14.25 × 103 mm3

The laboratory report on Chad Cron is sent electronically to the medical office from the laboratory that ran the test. After it prints at the medical office, Latisha retrieves it and places it on Dr. Diapedesis's desk for review. Which of the following indicates an abnormal value for Chad's CBC?

Lymphocytes: 41

The results of the differential cell count are included on Chad's laboratory report. Which of the following indicates an abnormal value?
