ANSWERS WITH RATIONALES|AGRADE
What is the gold standard for the suspected diagnosis of Celiac Disease? - answer-: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? - 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.
A 29 yo pregnant patient presents with a pulmonary embolus (PE). Which medication should
the nurse anticipate giving?
,A. low molecular weight heparin
B. Fondaparinux
C. Unfractionated heparin
D. Vitamin K - answer-:C. Unfractionated heparin
LMWH has less of an effect on thrombin compared to heparin
A nurse notes that a child has discoloration of several teeth. The nurse will ask about which
medication group?
A. Glucocorticoids
B. Tetracyclines
C. Sulfonamides
D. Salicylates - answer-:B. Tetracyclines
--Tetracyclines cause discoloration in developing teeth in children. Glucocorticoids are
associated with growth suppression. Salicylates are associated with Reye syndrome.
Sulfonamides are associated with kernicterus in newborns.
Which of the following medications is an alpha 1 and nonselective beta blocker?
A. Atenolol
B. Metoprolol
C. Propanolol
D. Carvedilol - answer-:D. Carvedilol
--Carvedilol is a nonselective β-blocker which, in addition, has alpha vasodilatory effects by
blockade of the α-receptor.
, If taken with a selective serotonin reuptake inhibitor (SSRI), which herbal product can increase
risk of serotonin syndrome?
A. St. John's wort
B. Kava kava
C. Ginkgo biloba
D. Valerian root - answer-:A. St. John's wort
--Taking St. John's wort with antidepressants might increase the risk of the accumulation of high
levels of serotonin in your body. Too much serotonin can cause mild to severe side effects.
A 12-year-old-child patient presents to the clinic and report signs and symptoms consistent with
asthma. How would the healthcare professional objectively confirm this diagnosis?
A. Draw serum levels of immunoglobulin E (IgE) and eosinophils
B. Measure expiratory flow rate and spirometry testing
C. Assess for parental history of asthma
D. Give a trial of asthma medication and check for improvement - answer-:B. Measure
expiratory flow rate and spirometry testing
--To objectively diagnose asthma, pulmonary function testing using spirometry can be
accomplished after a child is 5 to 6 years of age. Reduced expiratory flow rates that are
reversible in response to an inhaled bronchodilator would be characteristic abnormalities found
on a PFT.
According to CDC risk classification, a PPD measuring 7 mm in a patient living in a homeless
shelter is:
A. Negative results because induration is greater than 5 mm
B. Positive result because induration is less than 15 mm
