⫸ A 44-year-old woman has recently been diagnosed with advanced
metastatic non-small-cell lung cancer. Genetic testing is ordered to
determine if the patient's tumor has any genomic alterations and to guide
treatment decisions. A few weeks later, the patient's test results come
back positive for a genetic mutation. The APN starts osimertinib
(Tagrisso). Based on this information, what type of genetic mutation
does this patient have? Answer: EGFR mutation
⫸ A 20-year-old male meets with an advanced professional nurse
(APN) to discuss symptoms that have been slowly progressing over the
past several years. He is mainly concerned because he has been falling
frequently. Since childhood, his gait has consisted of walking on his
toes. During middle school, he was able to participate in sports but was
unable to participate in high school sports due to difficulty with running
and jumping. Lately, he has noticed it takes longer and is more difficult
to change positions from sitting to standing than it used to in the past. He
has also been waking up with muscle and joint stiffness. The APRN
notes that his family history is not significant for any chronic or genetic
diseases. Which condition is likely to be the cause of these symptoms?
Answer: Becker muscular dystrophy
--Becker muscular dystrophy (often called Becker MD or BMD) is a
form of muscular dystrophy, a genetic disorder that gradually makes the
body's muscles weaker and smaller. It causes less severe problems than
the most common type, Duchenne muscular dystrophy.

like to know if she should be worried. What should the provider do next
for this patient? Answer: Order a liver function test
⫸ A 75-year-old female presents to the emergency department with an
irregular heart rate of 130.What can be ascertained about this patient's
findings given the limited information? Answer: She is diagnosed with
atrial fibrillation and needs her heart rate controlled with metoprolol
(Lopressor).
⫸ Which condition from this patient's medical history is contributing to
the loss of contractility? Answer: Acute myocardial infarction
⫸ Which condition is this patient suffering from? Answer: Diabetic
ketoacidosis
⫸ A 45-year-old female fears that she is having a stroke and takes

tests, the patient is diagnosed with Cushing disease. Which lab
abnormality would be present in this patient? Answer: Increased cortisol
, ⫸ SOB when lying down, and moving around --Based on the patient's
presentation, which disease process is the patient likely exhibiting?
Answer: Asthma
⫸ A two-year-old child presents with a clear runny nose and cough
which has lasted 3 days. The child's mother reports the cough sounds
like a barking noise. The child is sleeping in the mother's arms and
appears to have stridor. The child's mother also reports an axillary
temperature of 101°F last night. Which management technique is
appropriate for this child's symptoms? Answer: Oral steroids and
breathing treatments
⫸ Delerium, urinary incontinence, fever-- Which lab and diagnostic
tests should be ordered as part of the patient's assessment? Answer:
Complete blood count, complete metabolic profile, and urinalysis
⫸ An 18-year-old male is involved in a motorcycle crash while not
wearing a helmet. He is brought into an emergency room and is
