____ is a hormone that promotes bone resorption (normal
destruction of the bone by osteoclasts)
Hypoparathyroidism, vitamin D deficiency, Hyperphosphatemia -
ANS-Decrease (Hypocalcemia)
Which one is false?
A. Hyperphosphatemia → high phosphorus in the blood
B. Pageant's disease → destruction of the bone, calcium release into
the blood - ANS-B; Paget's disease
,Determined by parathyroid gland function, vitamin D, intestinal
absorption, renal function, bone metabolism, nutrition - ANS-Serum
Phosphorus
Which one is correct about Vitamin D?
A. Vitamin D → enhances absorption of Calcium
B. Vitamin D promotes the absorption of Ag and I - ANS-A.
Note:
Vitamin D promotes the absorption of Ca and P
Which sentence is not correct?
(1) Kidneys are responsible for excreting phosphorus.
(2) In terms of parathyroid hormones, it is the same
(3) Calcium levels will increase while the phosphorus levels will
decrease in hyperthyroidism - ANS-2; it is the OPPOSITE
A medical procedure that involves testing a blood sample, urine, or
other substance from the body - ANS-Laboratory Test
Insertion to the skin - ANS-Invasive
Does not penetrate the body barrier - ANS-Non invasive
A medical procedure performed to help diagnose a disease or
condition - ANS-Diagnostic Test
[T/F] Lab tests should be ordered only if test results will not affect
decisions about patient care - ANS-F, will affect
,[T/F] Economic cost and impact of QOL (Quality of Life) related to
obtaining lab data must always be balanced by benefit to patient-
specific outcomes - ANS-T
[T/F] Normal Range are more preferred in clinical practice than
"reference range" - ANS-F; Reference Range are more preferred in
clinical practice than "normal range"
Lab findings, within and outside of reference range, aid in: (Odd one
out)
A. assessing clinical disorders
B. establishing diagnosis
C. assessing drug therapy, or
D. evaluating disease regression - ANS-D; it should be evaluating
disease progression
______ often necessary to evaluate disease progression and
response to therapy or to monitor development of toxicities
associated with therapy - ANS-Baseline lab tests
[T/F] Baseline lab tests are done before subjecting the patient to
drug therapy and are then compared before the administration of
the drug and after - ANS-T
[T/F] Lab findings must be assessed in context of pharmaceutical
situation and incorporate understanding of human physiology -
ANS-F; Context of clinical situation
[T/F] Lab findings are used to complement other positive and
negative findings and must not be evaluated in isolation - ANS-F;
Subjective and Objective findings
, [T/F] Lab test results are specific to the clinical lab conducting the
test (vary based on type of equipment and testing methods used) -
ANS-T
A substance or condition being tested was found - ANS-Positive
The number of cases incorrectly identified as patient (You don't
have the condition but you are positive) - ANS-False Positive
The number of cases correctly identified as patient (You have the
condition and you are positive) - ANS-True Positive
A substance or condition being tested was not found - ANS-
Negative
The number of cases correctly identified as healthy - ANS-True
negative
The number of cases incorrectly identified as healthy - ANS-False
negative
Not clearly positive or negative - ANS-Inconclusive
Ability of the test to correctly identify disease or condition - ANS-
Sensitivity
Ability of the test to rule out individuals who do not have disease or
condition - ANS-Specificity
Proportion of cases giving positive test results who are already
patients - ANS-Positive Predictive Value
