Hemorrhage secondary to heparin administration can be corrected by administration of:

 # Hemorrhage secondary to heparin administration can be corrected by administration of:

A. Vitamin K

B. Whole blood

C. Protamine

D. Ascorbic acid

The correct answer is C. Protamine.

The half life of intravenous heparin is about one hour and if a patient bleeds, it is usually sufficient just to discontinue the infusion; however if the bleeding is severe, the excess can be neutralized with intravenous protamine.

# Most reliable method of identification of a person is by:

# Most reliable method of identification of a person is by:

A. Anthropometry

B. DNA finger printing

C. Dactylography

D. Dentition

The correct answer is C. Dactylography.

• Derived from GK word daktylose-finger ,graphein- to write

Dactylography is the method of identification based on unique epidermal ridge pattern on the tips of fingers. It is a most accurate and unfailing method of positive identification. No Two Individual will have identical fingerprints It is better method of identification than DNA profiling. DNA profiling would be same in identical twins but fingerprints are different. Fingerprints remain permanent throughout life and even after death and in advance stage of decomposition. Fingerprints have general characteristic ridge patterns that permit them to be systematically classified. Pattern can be easily emailed and printed, enabling intercontinental criminals to be caught easily.

Marked salivary gland hypofunction

 # Stimulated whole salivary flow rate of less than _____ ml/min indicates marked salivary gland hypofunction. 

A. 0.6 

B. 0.7 

C. 0.8 

D. 0.9 

The correct answer is B. 0.7.

It is difficult to define absolute “normal” values for salivary output due to great interindividual variability and, consequently, a large range of normal values exists. About 0.3– 0.4 mL/min for unstimulated flow and 1.5–2.0 mL/min for stimulated flow are considered normal. Unstimulated whole

saliva flow rates of < 0.1 mL/min and stimulated whole saliva flow rates of < 0.7 mL/min are abnormally low and indicative of marked salivary gland hypofunction. Higher levels of output do not guarantee that function is normal, however, as they may represent marked hypofunction for some individuals. Therefore, these stated values represent a lower limit of normal and should serve only as a guide for the clinician.

The presence of fluoride in communal water supplies have demonstrated appreciably lesser benefits, this is due to:

 # The presence of fluoride in communal water supplies have demonstrated appreciably lesser benefits, this is due to 

A. Adverse effect 

B. Halo effect 

C. Bacteriostatic effect 

D. None of the above 

The correct answer is B. Halo effect.

Several studies concerning the reduced prevalence of dental caries associated with the presence of fluoride in communal water supplies have demonstrated appreciably lesser benefits, typically ranging between 18% and 30%. This decrease in attributable benefit is due to the so-called halo effect associated with the preparation of numerous foods and beverages in fluoridated communities and their consumption in nonfluoridated communities.
