Clostridium difficile is a gram-positive, spore-forming bacilli. The remaining organisms will all stain gram-negative on direct smear or smears made from culture. Which of the following organisms are gram-positive?

A. Neisseria gonorrhoeae

B. Brucella species

C. Clostridium difficile

D. Pseudomonas aeruginosa

Immunoassay is the most common technique that is used by clinical laboratories for therapeutic drug monitoring.
Most of the drugs commonly assessed with TDM can be measured on analytical platforms which utilize antibodies (in some form) for detection. Antibodies can be developed that recognize drugs. Although most drugs are much too small to evoke an immune response, scientists can conjugate drugs to immunogenic proteins to produce antibodies that recognize drug-specific epitopes.
Which of the following is the most common technique that is used by clinical laboratories for therapeutic drug monitoring?

A. Immunoassay

B. Electrophoresis

C. Atomic absorption

D. Ion selective electrode voltimetry

Platelets do not circulate in inactivated, spiny forms. The spiny, sticky form of the platelet is initiated once the platelets become activated in response to blood vessel damage. Which of the following is not true in terms of platelet characteristics?

A. Produced in the bone marrow by megakaryocytes.

B. Possess an inherent sticky property that aids in adhesion and aggregation.

C. Have a lifespan of roughly 9-12 days.

D. Are normally found circulating in their inactive, spiny form.

Alpha-fetoprotein is a substance typically used in the triple test during pregnancy and for screening chronic liver disease patients for hepatocellular carcinoma. Increased concentrations of alpha-fetoprotein (AFP) in adults are MOST characteristically associated with:

A. hepatocellular carcinoma

B. alcoholic cirrhosis

C. chronic active hepatitis

D. multiple myeloma

Gamma globulin (anti-D) is given to Rh-negative mothers to prevent any D antibody production, which could cause harmful effects in future pregnancies with an Rh-positive fetus. The administered anti-D will bind fetal Rh-positive cells that may come from the fetus in vivo; therefore the mother will not produce anti-D herself, preventing sensitization. A solution of gamma globulins containing anti-Rh (D) is given to an Rh (D) negative mother to:

A. Prevent fetal cells from initially sensitizing the mother

B. Neutralize any of the child's antibody that may have passed the placental barrier

C. Neutralize any natural maternal antibodies present

D. Prevent greater antibody response in a previously sensitized mother

The recommended disinfectant for blood and body fluid contamination is:

A. sodium hydroxide.

B. antimicrobial soap.

C. hydrogen peroxide.

D. sodium hypochlorite.

Flow cytometry employs a combination of fluorescent antibody tagging of cells and analysis with laser light scatter. What principle(s) of flow cytometry are employed when performing immunophenotyping:

A. Defraction gradients

B. Impedance
