BCNS CNS EXAM QUESTIONS AND ANSWERS
Adolescents are particularly vulnerable to pregnancy-induced:
Hypertension
Premature Delivery
A and B
Asthma - Answers :A and B
Pregnancy-induced hypertension can cause cardiovascular and kidney problems later.
Premature delivery is a leading cause of death among newborns. Inadequate nutrition
of the mother is related to both mental and physical birth defects.
No similar synthetic standards are available as of yet for the nutritional evaluation
techniques. Rather, it is necessary to coordinate one's work with that of established
laboratories. This may be accomplished by:
Comparing the analytical values obtained by the laboratory involved in the local
evaluation program
Values obtained from submitting replicate samples under code to a standard reference
laboratory
A and B
setting up your own standards - Answers :A and B
For the routine clinical chemical assay to work, standards, calibrators and plasma or
serum controls must be in place with precision of analytical procedures by coordinating
one's work with that of established laboratories. The analytical values must be
compared by the laboratory involved and submitting replicate samples to a standard
reference laboratory.
In terms of ethical considerations for research, which of the following statements is least
accurate?
any present (but not potential) conflict of interest must be stated
sources of funding for research must be reported
an oversight committee must be available to review procedures
all findings, both positive and negative must be reported - Answers :any present (but not
potential) conflict of interested must be stated
Explanation
,This is the least accurate statement. Any present or potential conflicts of interest must
be stated. Such things as owning stock in the company, or being a consultant to the
company must be reported by the researcher - both present and potential.
Currently, _____ % of calories in the U.S diets is derived from fat
20

40 - Answers :30
The American Heart Association's newest recommendation is to consume less or no
more than 7% of saturated fats, 8% polyunsaturated fats and 15% monounsaturated
fats.
The term for excessive hunger is which of the following?
glycosuria
polyuria
polydipsia
polyphagia - Answers :polyphagia
Explanation
The inability to metabolize glucose causes the body to break down its own tissue for
protein and fat. This response causes polyphagia, or excessive appetite, but at the
same time a loss of weight, weakness, and fatigue occur. The body's use of protein
from its own tissue causes it to excrete nitrogen.
Elevated bilirubin is:
nothing to be concerned about
neurotoxic
a concern for the heart
none of the above - Answers :Neurotoxic
Explanation:
Elevated bilirubin is neurotoxic and can lead to jaundice. It is conjugated with glucuronic
acid in the liver and excreted into bile from the liver.
Which of the following serum proteins has the function of transporting vitamin A in
plasma?
IGF-1
retinol-binding protein
prealbumin
albumin - Answers :retinol-binding protein
, Retinol-binding protein transports vitamin A in plasma. It also binds noncovalently to
prealbumin. It is catabolized in renal proximal tubular cells.
When properly prepared most, samples:
can be frozen- at least for a short period of time to await assay
must remain frozen until assayed, particularly if they are to be shipped some distance to
the analytical lab
can be shipped with dry ice in a properly insulated polystyrofoam container
all of the above - Answers :all of the above
Dry ice does not usually last more than 60-72 hours, under the best conditions. Some
enzymes, such as transaminases, are destroyed by refreezing, so taking precautions
are imperative.
what is the term for a patient who has returned to his or her old behaviors?
Maintenance
Preparation
Termination
Relapse - Answers :Relapse
Explanation:
When a patient returns to his or her former dietary patterns, it is referred to as a relapse.
The Registered Dietitian will work with their patient to discuss their challenges and
barriers to change, and then implement strategies to help guide them in the right
direction.
Vitamin K is often given to patients after excessive anticoagulant therapy because
these drugs destroy the bacteria in the intestines
to treat causes of hemorrhage
A and B
not an antidote for an overdose of blood thinners - Answers :A and B
Explanation:
Vitamin K can be given as an antidote for an overdose of anticoagulant (blood thinner)
such as warfarin - sometimes sold as Coumadin or Jantoven.
