Illustrated in the photomicrograph is the tail portion of an adult worm of a filarial nematode as it
may be observed in a peripheral blood smear. These worms measure up to 300 um in length and
commonly inhabit the lymphatics. This nematode species more commonly involves the
lymphatics of the inguinal region resulting in swelling below the knee in what is known as
elephantiasis. The species indicated in this exercise can be presumptively determined by the
orientation of nuclei within the tail sections. From the nematode species listed below, indicate
the most likely species identification
A) Brugia malayi
B) Wuchereria bancrofti
C) Loa Loa
D) Dirofilaria immitis Correct Answer: A) Brugia malayi

A) Normal serum amylase and elevated urine amylase values
B) Increased serum amylase and normal to low urine amylase values
C) Increased serum and increased urine amylase values
D) Normal serum and normal urine amylase values Correct Answer: B) Increased serum
amylase and normal to low urine amylase values
Which of the following describes the Westgard multi-rule 2^2S?
A) Two control data points are within +/- 2s
B) One control data point falls outside +/- and a second point falls outside -2s
C) Two consecutive data points fall outside +/- 2SD
D) Two consecutive data points fall inside +2s
E) Two points are within 2SD Correct Answer: C) Two consecutive data points fall outside +/-
2SD

the following conditions except:

level should the standard anticoagulant volume be adjusted?
A) <50%
B) >75%
C) >55%
D) <35% Correct Answer: C) >55%
Which of the following is a cause of metabolic alkalosis?
A) Late stage of Salicylate poisoning
B) Uncontrolled diabetes mellitus
C) Renal failure
D) Excessive vomiting Correct Answer: D) Excessive vomiting
Materials such as strong acids and bases are classified as:
A) Corrosives
