Continue the current Warfarin dose without changes.
Administer vitamin K to reverse the effects of Warfarin.
2. Which would be the priority intervention for the newborn of a mother
positive for hepatitis antigen?
The newborn should receive hepatitis B immune globulin within 12
hours of birth.
The newborn should receive the hepatitis B vaccine and hepatitis B
immune globulin within 24 hours of birth.
The newborn should be given the first dose of hepatitis B vaccine by 2
months of age.
The newborn should receive the hepatitis B vaccine and hepatitis B

medication. How should the APN address this concern regarding aspirin use?
Advise the patient to avoid all medications.
Reassure the patient that heart disease is not a concern.
Explain the benefits of low-dose aspirin in preventing heart disease.
Suggest alternative medications without discussing aspirin.
,4. 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
ALK mutation
MET amplification mutation
BRCA mutation
5. A diagnostic test is said to be highly specific and less sensitive. What does
this mean?
The test is better at identifying those who may develop the condition.
The test is better at identifying people who do not have the
condition.
The test is better at identifying those who have the condition.
The test is better at identifying how at risk a person is for a specific
condition.
6. Weight gain, constipation and sluggishness are symptoms of?
Inadequate secretion of insulin.
Inadequate secretion of cortisol.
Inadequate secretion of thyroid hormone.
Oversecretion of growth hormone.
,7. What would be the most likely outcome if a Parkinson's patient on levodopa
were also prescribed haloperidol?
Excessive somnolence
Hypertensive crisis
Excessive nausea and vomiting
Worsening symptoms of Parkinson's disease
Tachycardia and possible chest pain
8. What symptom is present in the patient that should be assisted first in the
emergency room?
Headache
Sprained ankle
Mild abdominal pain
Stiff neck
9. What medication is commonly recommended for patients with elevated
hemoglobin A1c who are already taking Metformin?
SGLT2 inhibitors
Thiazolidinediones
GLP-1 receptor agonists
Insulin
10. On a follow-up appointment, a mother of a newborn reports the infant
draws up the legs, clenches fists, and cries as if in pain. The mother reports
the symptoms usually occur during the evening but the baby tolerates
formula well. The nurse tells the mother that the baby has infantile colic. The
, mother inquires about the child's prognosis. How should the nurse describe
the prognosis of infantile colic to the patient's mother?
The etiology is unspecified, therefore the diagnosis is long-lasting.
Children will typically have symptoms until three years of age.
Children usually outgrow the condition at about three months of
age.
The child will outgrow colic symptoms at 12 months of age.
11. The practical nurse (PN) is reinforcing information to a older male client with
a history of coronary artery disease about his prescribed daily medication
regimen. Which medication is most likely to reduce the client's risk factors?
A potassium sparing diuretic.
A high daily Vitamin C dose.
A low protein binding antibiotic.
A low-dose aspirin given daily.
12. If the provider finds that the patient's ferritin levels continue to rise over the
next few months, what would be the most appropriate next step?
Increase the patient's iron intake.
Schedule a follow-up appointment in a year.
Investigate for potential underlying conditions such as
hemochromatosis.
Start the patient on iron supplements.
13. Describe the factors that an IV therapy nurse should consider when
prioritizing patients.
