CMAC- AMCA Exam 4- Practice Questions with Answers
1. which organization developed the guidelines for universal precautions?: -
CDC
2. according to OSHA, medical personnel must wear PPE (personal protective equipment) when they
have contact with which of the following?: blood
3. to detect pregnancy, either urine or blood serum is tested for the presence of which of the
following?: HCG hormone,
(it is human chorionic gonadotropin and a 1st voided morning specimen is used to collected,
the higher concentration of HCG means the patient is pregnant and a
blood test is more sensitive than a urine HCG test so it will detect pregnancy sooner)
4. a bacteriological culture needs to be performed on a collected urine spec- imen. which of the
following instructions best describe what your patient should do?: void a specimen midstream in a
sterile cup
5. if a urine specimen is collected and then left standing for more than one hour, bacteria will grow
causing the pH of the urine to soon become which of the following?: alkaline
(because of the bacteria, the urea in the urine will be converted to ammonia and the specimen
will become cloudy, if the specimen was positive for glucose then the glucose level will
decrease because the growing bacteria will feed upon it, also organized components will be
affected)
6. what is the pH range for normal urine?: 4.5 to 8.0
(higher pH is greater alkalinity and lower is more acidic and normal is 6.0)
,7. if a patient normally drinks 10 or more 8-oz glasses of water each day, urine would most likely be
which color?: straw
8. urine needs to be collected in which type of container if it is collected for bacterial culture?:
sterile
9. a routine analysis of urine is made up of which of the following sets of examinations?:
microscopic, chemical, physical
10.physical examination of urine: includes color, clarity, odor, and specific gravity (by reagent
strip or refractometer)
11.chemical examination of urine: done using reagent strips for pH, glucose, protein,
ketones, bilirubin, urobilinogen, blood, nitrate, and leukocytes
12.microscopic examination of urine: looks for RBCs, WBCs, epithelial cells, casts, crystals,
mucous threads, and possible bacteria and/or spermatoza
13.to prevent a urine specimen from becoming an unreliable pH sample, the specimen should be
which of the following?: tested within one hour of collection
14.if the required testing can be performed within 1st hour after collection what will be valid?:
the pH of the sample
15.when is refrigeration of urine sample done?: refrigeration will be necessary only if the sample
cannot be tested within the 1st hour of collection
16.what happens if a urine sample is kept at room temperature for more than 1 hour?: chemical
and microscopic changes in the urine will occur, thereby invalidating the certain tests results
17.when placing a urine specimen tube into the centrifuge for later creating a wet mount, where
should you place an identical tube containing water in that same centrifuge?: directly opposite the
, tube containing the urine specimen
18.what is the principal reason for bracing the hand holding the needle assembly against the
patient's arm during phlebotomy?: prevent excess needle movement
19.when a reagent strip is used to test a urine specimen and the result is positive for ketones, this
may be an indication of which condition?: diabetes mellitus
20.what do ketones point to?: a diet that is high in fat, or to diabetes mellitus, or starvation, or
body wasting
21.what is the measure of the degree of acidity or alkalinity of urine called?-
: pH
22.specific gravity: ratio of a mineral's weight compared with the weight of an equal
volume of water
23.routine urinalysis: performed to screen for urinary and systemic disorders
24.supernatant: Clear liquid remaining after sediment settles with pellet (precipi- tate) at the
bottom
25.all the steps listed are appropriate when performing a capillary puncture except for which of the
following?: placing a tourniquet around the finger
26.what will squeezing the finger too much while performing a capillary puncture do to the blood
sample?: the blood sample will contain an excessive amount of tissue fluid. this will result in a
poor-quality sample
27. what are steps that are appropriate when performing a capillary puncture?-
: gently rubbing the sides of the finger, discarding the first drop of blood, selecting the ring finge
of the hand
28. when would a capillary blood sample be diluted with tissue fluid?: the finger is squeezed
