/.Following routine colonoscopy screening, a client is told that he had several polyps
removed. The client began crying stating, "I just can't deal with cancer. I'm too young."
The nurse responds: A) "Don't worry. We have some great cancer doctors on staff. I'm
sure chemo will help you fight it." B) "Maybe if you're lucky, they have stopped it from
metastasizing to your liver." C) "A simple intestinal surgery will cure you." D) "Most
colon polyps are not cancerous. The biopsy results will direct your care." - Answer-
✅Ans: D Feedback: A polyp is a growth that projects from a mucosal surface, such as
the intestine. Although the term usually implies a benign neoplasm, some malignant
tumors also appear as polyps. Adenomatous polyps are considered precursors to
adenocarcinomas of the colon.
/.A lung biopsy and magnetic resonance imaging have confirmed the presence of a
benign lung tumor in a client. Which of the following characteristics is associated with
this client's neoplasm? A) The tumor will grow by expansion and is likely encapsulated.
B) The cells that constitute the tumor are undifferentiated, with atypical structure. C) If
left untreated, the client's tumor is likely to metastasize. D) The tumor is likely to infiltrate
the lung tissue that presently surrounds it. - Answer-✅Ans: A Feedback: Benign
neoplasms typically grow by expansion rather than invasion. As well, they are usually
contained within a fibrous capsule. Malignant tumors are associated with
undifferentiated cells, metastasis, and infiltration of surrounding tissue.
/.3. A newly diagnosed lung cancer client asks how his tumor spread (metastasized) so
fast without displaying many signs/symptoms. The nurse responds that malignant
,tumors affect area tissues by: A) Increasing tissue blood flow B) Providing essential
nutrients
C)Liberating enzymes and toxinsD)Forming fibrous membranes - Answer-✅Ans: C
Feedback: Malignant tumors affect area tissues by liberating enzymes and toxins that
destroy tumor tissue and normal tissue. In addition, the malignant cells compress area
vessels, causing ischemia and tissue necrosis. The high metabolic rate of tumor growth
causes the tumor to deprive the normal tissues of essential nutrients.
/.A client had a positive Pap smear. The surgeon diagnosed "cancer in situ of the
cervix." The client asks, "What does this mean?" From the following statements, which
is most appropriate in response to this question? The tumor has: A) Been walled off
within a strong fibrous capsule B) Developed a distant infiltration C) Not crossed the
basement membrane, so it can be surgically removed with little chance of growing back
D) Grown undifferentiated cells that no longer look like the tissue from which it arose -
Answer-✅Ans: C Feedback: Cancer in situ is a localized preinvasive lesion. As an
example, in breast ductal carcinoma, in situ the cells have not crossed the basement
membrane. Depending on its location, an in situ lesion usually can be removed
surgically or treated so that the chances of recurrence are small. For example, cancer in
situ of the cervix is essentially 100% curable.
/.While studying to become chemo-certified, the nurse reviews some basic concepts
about cancer cells. When a client asks about why the tumor grows so fast, the nurse will
respond based on which of the following physiological principles? Select all that apply.
A) Cancer cells have shorter cell cycle times than normal cells. B) Cancer cells do not
die when they are programmed to die. C) Growth factors prevents cancer cells from
entering resting (G0) cell cycle phase. D) Cancer cells will reach a balance between cell
birth and cell death rate. E) Cancer cells never reach a flattened growth rate. - Answer-
✅Ans: B, C Feedback: One of the reasons cancerous tumors often seem to grow so
rapidly relates to the size of the cell pool that is actively engaged in cycling. It has been
shown that the cell cycle time of cancerous tissue cells is not necessarily shorter than
that of normal cells. Rather, cancer cells do not die on schedule, and growth factors
prevent cells from exiting the cell cycle and entering the G0 or noncycling phase. The
ratio of dividing cells to resting cells in a tissue mass is called the growth fraction. The
doubling time is the length of time it takes for the total mass of cells in a tumor to
double. As the growth fraction increases, the doubling time decreases. When normal
tissues reach their adult size, an equilibrium between cell birth and cell death is
reached. Cancer cells, however, continue to divide until limitations in blood supply and
nutrients inhibit their growth. When this occurs, the doubling time for cancer cells
decreases. The initial growth rate is exponential and then tends to decrease or flatten
out over time.
/.Although growth rate is variable among types of bacteria, the growth of bacteria is
dependent on:
A) Biofilm communication
B) Availability of nutrients
C) An intact protein capsid
,D) Individual cell motility - Answer-✅Ans: B
Feedback:
Bacterial growth is dependent upon the availability of nutrients and physical growth
conditions. Bacteria prefer to colonize as biofilm and communicate with other bacteria
within the biofilm, but biofilm is not necessary for growth. Viruses (not bacteria) form a
capsid. Although some bacteria have projections for motility, these are not necessary
for growth.
/.Which of the following outpatients are at a greater risk for developing Treponema
pallidum, the cause of syphilis? Select all that apply.
A) A homeless adolescent female performing oral sex for money
B) A male who frequents clubs catering to exotic dancers and sexual favors
C) A homosexual male couple who have had a monogamous relationship for the past
20 years
D) An older adult female living in a condominium who regularly has sex with three to
four different men/week - Answer-✅Ans: A, B, D
Feedback:
Treponema pallidum is a sexually transmitted infection that is spread by direct physical
contact. The Borrelia type of spirochete is spread from animals to humans through lice
or tick bites. Leptospira spirochetes spread from animals to humans through contact
with infected animal urine. Spirochetes are anaerobic; therefore, they would not invade
the host through oxygen-filled aerobic lungs.
/.Chlamydiaceae have characteristics of both viruses and bacteria and are a rather
common sexually transmitted infectious organism. After entry into the host, they
transform into a reticulate body. The health care provider should monitor which of the
following clients for this possible infection? Select all that apply.
A) An adult male who raises a number of exotic birds in his home
B) A drug abuser looking to share needles/syringes
C) A newborn with a noticeable eye infection
D) A teenager who swims in the lake regularly - Answer-✅Ans: A, B, C
Feedback:
Chlamydiaceae are in the form of an elementary body when infectious and outside of
the host cell. Once an organism enters the cell, it transforms into a large reticulate body.
This undergoes active replication into multiple elementary bodies, which are then shed
into the extracellular environment to initiate another infectious cycle. Chlamydial
diseases of humans include sexually transmitted genital infections (Chlamydophila
trachomatis); ocular infections and pneumonia of newborns (C. trachomatis); upper and
lower respiratory tract infections in children, adolescents, and young adults
(Chlamydophila pneumoniae); and respiratory disease acquired from infected birds
(Chlamydophila psittaci).
/.A client has been diagnosed with Coxiella burnetii infection. She asked the health care
provider how she could have gotten this disease. The health care provider's best
response is:
A) "Probably while walking outside without your shoes on."
, B) "While swimming in an unsanitary pond."
C) "Drinking contaminated milk."
D) "Eating undercooked fish." - Answer-✅Ans: C
Feedback:
In humans, Coxiella infection produces a disease called Q fever, characterized by a
nonspecific febrile illness often accompanied by headache, chills, arthralgias, and mild
pneumonia. The organism produces a highly resistant sporelike stage that is transmitted
to humans when contaminated animal tissue is aerosolized (e.g., during meat
processing) or by ingestion of contaminated milk.
/.A teenage male develops a severe case of "athlete's foot." He asks, "How did I get
this?" The health care worker explains that certain fungi become infectious (called
dermatophytes) and exhibit which of the following characteristics? A) Prefer to grow in
warm environments like shoes/socks
B) Like a moist environment
C) Limited to cooler cutaneous surfaces
D) Need higher blood flow to survive - Answer-✅Ans: C
Feedback:
Dermatophytes are not able to grow at core body temperature, preferring the cooler
surface skin areas instead of moist skin folds. Diseases caused by these organisms,
including ringworm, athlete's foot, and jock itch, are collectively called superficial
mycoses.
/.A male client with a history of angina has presented to the emergency department with
uncharacteristic chest pain, and his subsequent ECG reveals T-wave elevation. This
finding suggests an abnormality with which of the following aspects of the cardiac
cycle?
A) Atrial depolarization
B) Ventricular depolarization
C) Ventricular repolarization
D) Depolarization of the AV node - Answer-✅Ans: C
Feedback:
The T wave on electrocardiography (ECG) corresponds to ventricular repolarization.
Atrial depolarization is represented by the P wave and ventricular depolarization by the
QRS complex. The isoelectric or zero line between the P wave and the Q wave
represents depolarization of the AV node, bundle branches, and Purkinje system.
/.During ventricular systole, closure of the atrioventricular (AV) valves coincides with:
A) Atrial chamber filling
B) Aortic valve opening
C) Isovolumetric contraction
D)Semilunar valves opening - Answer-✅Ans: C
Feedback:
Ventricular systole is divided into two parts: isovolumetric contraction when the AV
valves close and ventricles fill; and the ejection period, when the semilunar valves open
and blood is ejected through the aortic valve into circulation. Immediately after closure
