1. What is the definition of "prognosis" in a clinical context? A
prognosis is the predicted outcome of recovery from a disease. It
provides a forecast of the likely course of an illness and the patient's
chances of recovery.
2. Describe the methodology of a double-blind study in health
research. A double-blind study is a research design in which neither
the study participants nor the researchers know who is receiving the
, active treatment and who is receiving a placebo. This method is used
to prevent bias in the research findings.
3. Explain the key difference between hypoxia and ischemia as
causes of cellular injury. Hypoxia refers specifically to a low level of
oxygen within cells or tissues. Ischemia is a broader condition defined
by decreased blood flow, which leads to a deficit of both oxygen and
other essential nutrients.
4. How does radiation therapy target and destroy cancerous
tumors? Radiation therapy primarily works by destroying cells that are
rapidly dividing. Because cancer cells are characterized by
uncontrolled, rapid division, they are more susceptible to the effects of
radiation than many normal body cells.
5. What is the clinical significance when a patient develops
neutropenia during chemotherapy? The development of
neutropenia during chemotherapy is a serious adverse effect that
indicates the patient is at a high risk for infection. This condition
compromises the body's immune defenses, making the patient
vulnerable to pathogens.
6. List and briefly describe the three stages of the General
Adaptation Syndrome in response to stress. The General
Adaptation Syndrome consists of three stages. The Alarm stage is the
initial "fight-or-flight" response. The Resistance stage follows, where
the body adapts to the ongoing stressor. If the stress is prolonged, the
body enters the Exhaustion stage, which can lead to system
breakdown.
7. What is the inheritance pattern for autosomal dominant
disorders? For autosomal dominant disorders, the inheritance of only
one copy of the affected allele is needed to cause the disorder.
Therefore, only one parent needs to carry the allele to pass the
condition on to their offspring.
8. Differentiate between a screening test and a diagnostic test
for a condition like Down syndrome. A screening test, such as an
ultrasound or maternal blood test, estimates the risk or probability that
a fetus has a condition like Down syndrome. A diagnostic test, such as
amniocentesis or chorionic villus sampling (CVS), provides a definitive
confirmation of whether the condition is present.
9. Identify the two primary stress hormones and outline their
main physiological effects. The two primary stress hormones are
epinephrine/norepinephrine and cortisol. Epinephrine and
norepinephrine increase heart rate and blood pressure as part of the
