Complete Review | Graded A+
1. Describe the functions of the rough endoplasmic reticulum (ER) and smooth
endoplasmic reticulum (ER) in cellular processes.
The rough ER synthesizes lysosomal enzymes, while the smooth ER
synthesizes lipids and steroid hormones.
The rough ER synthesizes carbohydrates, while the smooth ER
synthesizes nucleic acids.
Both rough and smooth ER synthesize proteins exclusively.
The rough ER is involved in DNA replication, while the smooth ER is
involved in protein synthesis.
2. What are the three main components that make up the structure of a cell?
Golgi apparatus, lysosomes, and peroxisomes.
Nucleus, cytoplasm, and plasma membrane.
Cell wall, chloroplasts, and vacuoles.
Mitochondria, ribosomes, and endoplasmic reticulum.
3. What does the term 'reliability' refer to in the context of measurement
results?
The validity of the measurement in assessing what it is intended to
measure.
The degree to which a measurement can predict future outcomes.
The accuracy of the measurement compared to a standard.
The consistency of results upon repeated measurements.
,4. A nursing educator is explaining how the best clinical practices are
determined. Which statement best explains the purpose of evidence-based
practice?
It ensures that all patients receive holistic care.
It guarantees that care delivered is based on research.
It provides a definite reason for providing care in a specific manner.
It prevents errors when care is being delivered.
5. A replacement of squamous esophageal epithelium with goblet cells in
Barrett esophagus is known as
Hyperplasia
Metaplasia
Dysplasia
Atrophy
6. The sensitivity of a test is:
The percent of patients without the disease who have a negative test
The percent of patients with the disease who have a positive test
The percent of patients with a negative test who do not have the
disease.
The percent of patients with a positive test who have the disease
7. What is the function of the plasma membrane?
Communicating directly with the cell nucleus
Organizing cellular processes
, Creating ATP
Regulating transportation of materials in and out of a cell
Producing proteins and hormones
8. In a scenario where a patient has a severe injury affecting their muscle tissue,
what implications might this have for their overall mobility?
The injury would enhance the patient's muscle strength.
The injury would only affect the nervous tissue.
The injury would have no impact on mobility.
The injury could significantly impair the patient's ability to move.
9. Describe why endometrial hyperplasia is classified as an abnormal condition
rather than a normal physiological occurrence.
Endometrial hyperplasia is a normal response to hormonal changes.
Endometrial hyperplasia is normal as it occurs during the menstrual
cycle.
Endometrial hyperplasia is classified as abnormal because it
involves an excessive proliferation of endometrial cells, which can
lead to complications such as cancer.
Endometrial hyperplasia is only abnormal in postmenopausal women.
10. Describe the role of lysosomes in maintaining cellular health.
Lysosomes control free radicals within the cell.
Lysosomes synthesize lipids for cell membranes.
Lysosomes digest cellular waste, helping to maintain cellular
health.
, Lysosomes produce ATP for energy.
11. What is the primary characteristic of active transport in cellular processes?
It requires energy to move ions against a gradient.
It moves ions along their concentration gradient.
It is a passive transport mechanism.
It occurs without energy input.
12. A community health program aims to reduce the incidence of diabetes.
Which type of prevention would be most appropriate for this initiative?
Quaternary prevention
Primary prevention
Tertiary prevention
Secondary prevention
13. What is the definition of dysplasia in cellular growth?
Uncontrolled cellular division
Accelerated cellular death
Normal cellular growth
Disordered cellular growth
14. Describe the difference between apoptosis and necrosis in terms of cellular
processes.
Apoptosis leads to inflammation, while necrosis does not.
Apoptosis is reversible, while necrosis is irreversible.
