What is the gold standard for the suspected diagnosis of Celiac Disease?
Endoscopy with small intestine biopsy
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?
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?
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.

A female patient presents to an office to establish care. Her previous primary care provider
told her to follow up regarding an elevated ferritin level. She has no previous medical
history and is currently asymptomatic. She is concerned about the elevated ferritin and
would like to know if she should be worried. What should the provider do next for this
patient?
Order a liver function test
