How |is |the |Mean |Cell |Volume |calculated?
A) (Hemoglobin/RBCs) |x |10
B) (Hemoglobin/ |RBCs) |x |100
C) (Hematocrit |%/ |RBCs) |x |10
D) (Hematocrit |% |/ |Hemoglobin) |x |100
C) |(Hematocrit |%/ |RBCs) |x |10
The |Mean |Cell |Volume, |or |MCV, |can |be |calculated |by |dividing |the |hematocrit |(%) |by |the |red
|blood |cell |count |and |multiplying |by |10. |The |MCV |describes |the |volume, |or |size, |of |the |red |blood
|cell |population.
The |Mean |Cell |Hemoglobin, |or |the |MCH, |can |be |calculated |by |dividing |the |hemoglobin |(g/dL) |by
|the |red |blood |cell |count |and |multiplying |by |10. |The |MCH |represents |the |average |weight |of
|hemoglobin |in |red |blood |cells.
The |Mean |Cell |Hemoglobin |Concentration, |or |the |MCHC |can |be |calculated |by |dividing |the
|hemoglobin |(g/dL) |by |the |hematocrit |(%) |and |multiplying |by |100. |The |MCHC |is |the |ratio |of
|hemoglobin |mass |to |volume |of |RBCs.
Which |of |the |following |is |characteristic |of |an |exudate |effusion?
A) Leukocyte |count |greater |than |1,000 |WBC/microliter
B) Clear |appearance
C) Protein |concentration |less |than |3.0g/dL
D) Absence |of |fibrinogen
A) Leukocyte |count |greater |than |1,000 |WBC/microliter
Effusion |is |the |increase |of |fluid |between |the |serous |membranes |due |to |disruption |of |the
|mechanisms |of |formation |and |reabsorption |of |serous |fluid. |Exudates |are |caused |by |conditions
|affecting |the |particular |cavity |such |as |infections |and |malignancies.
Exudate |effusion |characteristics |include:
,- Leukocyte |count |greater |than |1,000WBC/microliters
- Fluid: |Serum |Protein |ratio |>0.5
- Yellow |or |cloudy |appearance
- Possible |spontaneous |clotting
Which |bacterial |species |is |most |likely |represented |by |the |spreading, |gray-white, |beta-hemolytic
|colonies |with |a |"frosted |glass" |appearance |as |illustrated |in |the |photograph?
A) Burkholderia |pseudomallei
B) Listeria |monocytogenes
C) Bacillus |cereus
D) Streptomyces |anulatus
C) |Bacillus |cereus
Bacillus |cereus |colonies |are |characteristically |spreading |gray-white, |and |beta |hemolytic |with
|"frosted |glass" |appearance.
Burkholderia |pseudomallei |also |produces |spreading |colonies, |but |they |are |more |wrinkled |in
|appearance |and |without |beta |hemolysis
Listeria |monocytogenes |produces |small, |round, |translucent |colonies |that |characteristically |have |a
|narrow |zone |of |beta |hemolysis, |noted |if |colonies |are |removed.
The |nocardioform |bacteria |Streptomyces |(formerly |gresus) |anulatus |produces |opaque, |chalky,
|white |colonies, |This |species |can |also |be |suspected |if |the |colonies |have |a |pungent, |musty |basement
|odor.
The |element |that |is |indicated |by |the |arrow |is |a:
A) Red |blood |cell |cast
B) Granular |cast
C) Hyaline |cast
D) Renal |tubular |epithelial |cast
A) Red |blood |cell |cast
This |is |a |red |blood |cell |cast. |RBCs |can |be |identified |within |the |matrix |of |the |cast. |The
|identification |of |the |cast |as |a |red |blood |cell |cast |is |supported |by |the |appearance |of |RBCs |outside |of
|the |cast.
Granular |casts |are |composed |of |plasma |protein |aggregates |and |cellular |remnants. |Their |presence |in
|the |urine |may |be |of |pathologic |or |onpathologic |significane. |Granular |casts |appear |as |coarse |or |fine
|granules |in |cast |matrix.
,Hyaline |cats |generally |appear |colorless, |homogeneous, |and |transparent |with |rounded |ends. |They
|can |also |be |seen |as |a |result |of |dehydration, |after |diuretic |therapy, |in |renal |disease, |and |transiently |as
|a |result |of |exercise.
Renal |tubular |epithelial |(RTE) |casts |are |cause |by |the |sloughing |of |necrotic |renal |tubular |cells |due |to
|advance |tubular |destruction. |RTE |cells |are |usually |seen |as |a |part |of |the |cast.
A |mean |value |of |100 |mg/dL |and |a |standard |deviation |1.8mg/dL |were |obtained |from |a |set |of |glucose
|measurements |on |a |control |solution. |Based |on |95% |confidence |interval |(in |mg/dL), |what |would |be
|the |calculated |2 |SD |upper |and |lower |limits |for |this |control?
A) 94.6 |to |105.4
B) 96.4 |to |103.6
C) 97.3 |to |102.7
D) 98.2 |to |101.8
B) 96.4 |to |103.6
The |95% |confidence |interval |can |also |be |described |as |the |probability |that |95% |of |the |time, |the
|quality |control |will |fall |within |+/- |2 |standard |deviation |of |the |mean. |In |this |case, |2 |standard
|deviations |would |be |calculated |as |1.8mg/dL |multiplied |by |2 |which |equals |3.6mg/dL.
Therefore, |the |calculated |2SD |(3.6mg/dL |plus |and |minus |the |mean) |based |on |the |95% |confidence
|interval |would |be |96.4 |- |103.6.
Which |of |the |following |sources |of |error |will |give |a |false |negative |result |in |antihuman |globulin
|testing?
A) Low |pH |of |saline
B) Dirty |glassware
C) Samples |collected |in |gel |separator |tubes
D) Refrigerated |specimen
C) Samples |collected |in |gel |separator |tubes
A |low |pH |of |saline |is |indicated |as |a |false |negative |source |of |error |in |antihuman |globulin |testing.
Dirty |glassware, |samples |collected |in |gel |separator |tubes, |and |refrigerated |specimens |are |all
|indicated |as |false |positive |sources |of |error |in |antihuman |globulin |testing.
Lymphocyte |pleocytosis |refers |to |a(n) | in |a |CSF |when |compared |to |a |normal |shape.
A) Increased |number |of |lymphocytes
B) Decreased |number |of |lymphocytes
, C) Normal |number |of |lymphocytes
D) Absence |of |lymphocytes
A) Increased |number |of |lymphocytes
The |presence |of |a |greater |than |normal |number |of |lymphocytes |in |the |spinal |fluid |is |termed
|lymphocyte |pleocytosis. |Typically, |the |majority |of |cells |seen |in |a |normal |adult |CSF |specimen |are
|lmyphocytes |and |monocytes |(7:30 |ratio). |This |ratio |is |reversed |in |children.
Which |of |the |following |donors |could |be |accepted |for |blood |donation?
A) 22-year |female |who |is |currently |pregnant
B) 40-year |old |female |who |lived |in |London |from |1988-1995
C) 44-year |old |male |who |used |a |needle |to |administer |nonprescription |drugs
D) 24-year |old |man |who |had |a |tooth |extraction |two |months |ago.
D) |24-year |old |man |who |had |a |tooth |extraction |two |months |ago.
A |tooth |extraction |that |occurred |two |months |ago |would |not |be |a |reason |for |rejection |as |a |blood
|donor.
Potential |donors |who |are |currently |pregnant |or |have |been |pregnant |in |the |past |6 |weeks |are |deferred
|from |donating |blood.
Potential |donors |who |have |spent |time |in |the |United |Kingdom |or |Europe |are |at |risk |for |variant
|Creutzfeldt-Jakob |disease |and |are |deferred |from |donation.
All |of |the |following |statements |are |true |regarding |the |significance |of |performing |direct |microscopic
|examinations |of |specimens |for |culture, |EXCEPT:
A) Provide |a |quality |control |comparison |to |the |culture |for |actual |isolates |recovered.
B) It |can |provide |the |physician |with |a |rapid |presumptive |diagnosis
C) It |may |serve |as |a |guide |for |selecting |appropriate |culture |media |based |on |microorganisms
|observed.
D) Allows |the |microbiologist |to |discard |the |sample |and |cancel |testing |if |no |organisms |are
|observed.
D) |Allows |the |microbiologist |to |discard |the |sample |and |cancel |testing |if |no |organisms |are |observed.
The |microscopic |examination |does |not |determine |whether |or |not |a |culture |is |going |to |grow |the
|organism, |as |the |culture |is |oftentimes |able |to |enhance |organisms |that |may |not |have |been |visible |via
|gram |stain, |but |will |growl |well |in |culture |media.
