test?
a. 10%
b. 25%
c. 50%
d. 75%
e. 100%
Answer:

QUESTION
A mother brings her 8-year-old daughter to the clinic because she found a tick in the girl's hair
and would like her daughter to be tested for Lyme disease. The nurse practitioner (NP) explains
that the enzyme-linked immunosorbent assay (ELISA), an early test for Lyme disease, is
effective in finding early cases of Lyme disease but can also give positive results in some people
who do not have the disease, making additional testing necessary. This means that the ELISA
test has which of the following?
a. Low sensitivity, high specificity
b. High sensitivity, high specificity
c. High sensitivity, low specificity
d. Low sensitivity, low specificity
e. Undetermined sensitivity and specificity
Answer:
c. High sensitivity, low specificity
QUESTION
A theoretical laboratory test for infection with HIV is known to have high sensitivity. This
means that the test has which of the following?
a. Good ability to rule in HIV in those who do have HIV
b. Good ability to rule out HIV in those who do not have HIV
c. High intraobserver reliability
d. High interobserver reliability
e. Good ability to diagnose AIDS
Answer:
b. Good ability to rule out HIV in those who do not have HIV
QUESTION
A theoretical new laboratory test for strep throat has high specificity. When a test has high
specificity, clinicians can be confident in which of the following aspects?
a. If the test result is positive, the patient probably has strep throat.
b. If the test result is positive, the patient probably does not have strep throat.
c. If the test result is negative, the patient probably has strep throat.
d. If the test result is negative, the patient probably does not have strep throat.
e. If the test result is positive, a confirmatory test should be performed.
Answer:
a. If the test result is positive, the patient probably has strep throat.
QUESTION
Weight change may indicate the presence of important underlying pathology requiring further
investigation. Which of the following best describes a significant weight change that requires
further evaluation?
a. A 45-year-old male with baseline weight of 280 lb who decides to undertake a light exercise
regimen and loses 15% of
his total body weight in 3 months
b. A 32-year-old female with a baseline weight of 175 lb who checks her weight irregularly but
reports a 5-lb unintended weight loss over 3 months
c. A 45-year-old recently menopausal female who gains 5% beyond her baseline weight of 140
lb in 6 months
d. A 26-year-old female with a baseline body mass index (BMI) of 25 who loses 5% of her body
weight with 6 months of diet and exercise modification
e. A 31-year-old male with a baseline body mass index (BMI) of 20 who loses 3 lb after a
prolonged bout of infectious gastroenteritis
Answer:
