ANSWERS) |ALREADY GRADED A+||NEWEST EXAM!!
An adult patient has experienced a third-degree burn. An
advanced practice registered nurse (aprn) is attempting to
calculate the total body surface area affected using the
rule of nines. The areas involved include the anterior and
posterior right arm and leg and the groin.
What is the estimated total body surface area that will be
assigned by the aprn?
27 1/2%
28%
18%
14 1/2% - answer-28%
The head represents 9%, each arm is 9%, the anterior
chest and abdomen are 18%, the posterior chest and back
are 18%, each leg is 18%, and the perineum is 1%. For
children, the head is 18%, and the legs are 13.5% each.
An advanced practice registered nurse (aprn) is caring for
a patient who experienced a 20% total body surface area
(tbsa) burn injury. Current assessment findings include
massive evaporative water losses, a flux of large amounts
,2|Page
of fluid and electrolytes in the tissues, generalized edema,
and circulatory hypovolemia. The aprn needs to take
immediate action to prevent irreversible hypovolemic
shock and death.
Which priority action should be taken by the aprn?
Infuse 2 l of hypertonic saline solution over one hour
Administer 1 l of d5w over 1/2 hour
Administer up to 30 l of lactated ringer solution over 24
hours
Infuse 0.45% nacl at maintenance rate over 12 hours -
answer-administer up to 30 l of lactated ringer solution
over 24 hours
Transcription - answer-is the process by which the
information in a strand of dna is copied into a new
molecule of messenger rna (mrna).
Amniocentesis is recommended for which pt? - answer-
amniocentesis is recommended for pregnant women 35
and older, women with a positive prenatal screening test,
chromosomal condition or neural tube defect in previous
pregnancy, family history of genetic disorders, or abnormal
ultrasound results. An amniocentesis is usually carried out
at about 16 weeks' gestation.

Nondisjunction - answer-means that a pair of homologous
chromosomes has failed to separate or segregate at
anaphase so that both chromosomes of the pair pass to
the same daughter cell. This probably occurs most
commonly in meiosis, but it may occur in mitosis to
produce a mosaic individual.
What is the most common cause of down syndrome? -
answer-maternal nondisjunction
Nondisjunction results in an embryo with three copies of
chromosome 21 instead of the usual two. In the majority of
cases, the extra copy of chromosome 21 comes from the
mother in the egg.
When a child inherits a disease that is autosomal
recessive, it is inherited from whom? - answer-both
parents
To have an autosomal recessive disorder, you inherit two
mutated genes, one from each parent. These disorders
are usually passed on by two carriers
Cystic fibrosis is caused by what type of gene? - answer-
autosomal recessive
That means a person must have a mutation in both copies
of the cftr gene to have cf.

Prader-willi syndrome causes a chromosomal defect that
is what? - answer-prader-willi syndrome is a genetic
disorder usually caused by deletion of a part of
chromosome 15 passed down by the father.
A 2-year old boy presents to the clinic with a fever. During
the physical exam the np observes koplik's spots inside of
his buccal mucosa. Which would be the most important to
assess on this patient to aid in an appropriate diagnosis?
Vaccination status
Rapid strep test
Swallowing evaluation - answer-vaccination status
Koplik spots are seen with measles. They are small, white
spots (often on a reddened background) that occur on the
inside of the cheeks early in the course of measles.
A 17-year old female was diagnosed with angular cheilitis
as a result of iron deficiency anemia. She had treatment
failure after a course of topical antibiotics, topical steroids,
moisture barrier creams, and antifungals were prescribed.
What would be the most appropriate next step in this
patient's plan of care?
Refer the patient to an allergist
