Questions and Answers All Correct
with Rationales
Tissue repair through regeneration occurs in which cells?
A. Parent
B. Parenchymal
C. Stromal
D Daughter - Answer- B.
Rationale:
Tissue repair can take the form of regeneration in which injured parenchymal cells are
replaced with cells of the same type, sometimes leaving no residual
Trace of previous injury. The stromal cells are found in the supporting connective
tissues, blood vessels, fibroblasts, nerve fibers, and the extracellular matrix.
These cell populations rely on progenitor or parent cells of the same lineage that have
not yet differentiated. Progenitor cells are sufficiently
ated so that their daughter cells are limited to the same cell line, but they have not
reached the point of differentiation that precludes the potential for active
proliferation.
A client is experiencing the early stages of an inflammatory process and develops
leukocytosis. The nurse recognizes this as a/an:
A. increase in circulating neutrophils.
B. decrease in eosinophils at the tissue injury site.
C. decrease in blood supply to the affected area
D. increase in cell production. - Answer- A. Rationale:
Leukocytosis, or the increase in white blood cells, is a frequent sign of an inflammatory
response, especially those caused by bacterial infection.
Leukocytosis occurs due to an increase in circulating neutrophils and eosinophils.
Leukocytosis does not occur because of increased cell production, and
blood supply is typically increased as part of the inflammatory process.
An oncology client is about to begin chemotherapy. During the education, the nurse
mentions that continuously dividing cells will be most affected by the chemotherapy.
The client asks, "What are continuously dividing cells?" The nurse responds, "These are
cells that continue to divide and replicate like. Select all that apply.
A. heart muscle cells."
B cells in your mouth."
C. cells on the surface of your skin."
D. cells lining your Gl tract."
E. neurons." - Answer- B. C. D.
,Rationale:
Continuously dividing or labile tissues are those in which the cells continue to divide and
replicate throughout life, replacing cells that are continually being destroyed. They
include the surface epithelial cells of the skin, oral cavity, vagina, and cervix; the
columnar epithelium of the gastrointestinal tract, uterus, and fallopian tubes; the
transitional epithelium of the urinary tract; and bone marrow cells. Neurons lose their
ability to proliferate once development of the nervous system is complete. Heart muscle
cells were believed to not regenerate; however, recent findings suggest that about half
of your heart's muscle cells are normally replaced over a lifetime. However, it is a slow
process and these cells are not continuously dividing.
The nurse admitting a client with an infected leg wound notes that the client has a
history of peripheral vascular disease, COPD, diabetes, and
gastroesophageal reflux disease (GERD). Which disorders increase the client's risk for
wound complications? Select all that apply.
A. Diabetes
B. Peripheral vascular disease
C. GERD
D. COPD - Answer- A. B. D.
Rationale:
The disorders that would increase the client's risk for wound complications include
peripheral vascular disease, COPD, diabetes and those disorders that
impede adequate blood flow and oxygen delivery to the wound bed.
When caring for a client during the proliferative phase of wound healing, the nurse
teaches the client that which of these processes is taking place?
A. Fibroblasts secrete collagen for wound healing.
B. Scar tissue formation is complete.
C. Fibrinogen is converted to fibrin to form a blood clot in the area.
D. White blood cells phagocytize bacteria and cellular debris. - Answer- A. Rationale:
During the proliferative phase, fibroblasts synthesize and secrete collagen and other
intercellular elements needed to fill the wound space. Fibroblasts also produce a family
of growth factors that induce angiogenesis and endothelial cell proliferation and
migration.
What should the nurse administer to a client who was bitten by a stray cat?
A. Administration of oral steroids
B. One oral dose of antibiotics
C. Varicella vaccination
D. Tetanus immunization - Answer- D. Rationale:
Tetanus immunization is recommended for an animal bite, especially for a stray cat.
Oral steroids and one dose of antibiotics would not be beneficial to
prevent an infection. The varicella vaccine prevents chicken pox.
The nurse is caring for a client with a chronic wound. The most important intervention
for the nurse to include in the plan of care would be:
, A. Protein-controlled diet
B. Vitamin C and zinc supplements
C Low/-carbohydrate diet
D. Steroid therapy - Answer- B. Rationale:
Vitamins play an essential role in the healing process. Vitamin C is needed for collagen
synthesis. Zinc has been found to aid in re-epithelialization. Vitamin
C and zinc supplements are often ordered for clients with chronic wounds to promote
wound healing. Steroid therapy would decrease wound healing. A
diet high in proteins and carbohydrates would be ordered to promote wound healing.
A client tells the health care provider he has heard several myths about viruses. The
most appropriate information for the nurse to provide would be:
A. "Viruses kill cells they come in contact with immediately."
B. "Viruses can produce symptoms of disease months to years later."
C. "Viruses are capable of replicating outside of a living cell."
D. "Viruses do not require a host cell to replicate." - Answer- B.
Rationale:
Viruses can produce symptoms of disease months to years later. Some viruses, such
as hepatitis C, can remain latent for long periods of time without
causing disease until months to years later. Viruses are incapable of replicating outside
of a living cell and are incapable of replication unless in a host cell.
Not every virus causes lysis and death of the host cell during replication.
A client complains of general malaise and fatigue and has a mild fever. The nurse would
evaluate this stage of disease as the:
A. Prodromal stage
B. Convalescent stage
C. Resolution stage
D. Incubation stage - Answer- A. The hallmark of the prodromal stage is the initial
appearance of symptoms in the host that are mild and nonspecific. The other
stages/symptoms would not
A client in the second trimester of pregnancy arrives for the first prenatal visit and
admits that she and her partner traveled to South America where they
went on a rain forest excursion when she was 4 weeks' pregnant. Which congenital
mosquito-borne abnormality may be seen on ultrasound if the fetus is
affected?
A. microcephaly
B. gastroschisis
C. syndactyly of the hands
D. spina bifida - Answer- A.
Rationale:
The Zika virus is a flavivirus transmitted by mosquitoes. Investigation by the World
Health Organization revealed that it was assocated with neonates being born with
microcephaly. More work is needed to uderstand the impact of Zika on transmission
cycles and disease burden in both human and nonhuman populations. Spina bifida is a
