Before initiating cetuximab therapy, the provider will order epidermal growth factor receptor (EGFR) testing for the patient having which condition?

• Breast cancer
• Colorectal cancer
• Bone cancer
• Brain cancer - Correct Answer - B Colorectal cancer

Cetuximab is used mainly for metastatic colorectal cancer. The medication works only against tumors that express EGRF; all other tumors are unresponsive. This makes testing in advance of treatment required. Cetuximab is not appropriate for any of the other conditions listed.

A child attending daycare is prescribed 750 mg of an antibiotic for 10 days. The drug may be dosed in several ways and is available in two concentrations. Which dosing regimen will the provider consider to best assure drug adherence?

• 375 mg of a 250 mg/5 mL solution PO twice daily
• 250 mg of a 250 mg/5 mL solution PO three times daily
• 250 mg of a 500 mg/5 mL solution PO three times daily
• 375 mg of a 500 mg/5 mL solution PO twice daily - Correct Answer – D 375 mg

of a 500 mg/5 mL solution PO twice daily 1 / 4

pg. 2 To promote adherence to a drug regimen in children, it is important to consider the size & timing of the dose. In this case the preparation containing 500 mg/5 mL means that a smaller volume can be given, which is more palatable to a child.Twice daily dosing is more convenient for parents, especially when a child is in daycare or school; it also helps prevent the problem of the medication being left either at home or at school.

A 5-year-old has gray teeth. When taking a medication history, the provider will ask about previous use of which group of medications?

• Glucocorticoids
• Salicylates
• Sulfonamides
• Tetracyclines - Correct Answer - D. 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.

An infant developed a pruritic rash following exposure to an allergen. The infant's parents ask the provider about using a topical antihistamine. What information should the provider use to address the parents' question?

• Antihistamines given by this route are not absorbed as well in children.
• Applying an antihistamine to the skin can cause toxicity in this age group.
• The child will also need oral medication to achieve effective results.
• Topical medications have fewer side effects than those given by other routes. -

Correct Answer - B Drug absorption through the skin is more rapid in infants, because their skin is thinner & has greater blood flow; therefore, infants are at increased risk of toxicity from topical drugs. Because of increased drug absorption through the skin, infants should not be given additional drugs via other routes. If a drug is more likely to be absorbed rapidly, it will have more side effects. 2 / 4

pg. 3 A patient with bipolar disorder who has been taking lithium for several years has developed a goiter. When the serum tests reveal hypothyroidism what will the provider prescribe for this patient?

• Levothyroxine therapy
• Increasing the lithium dose
• Iodine supplements daily
• Propylthiouracil - Correct Answer - A

Patients taking lithium may experience reduced incorporation of iodine into the thyroid hormone, resulting in goiter and hypothyroidism. Administration of levothyroxine or withdrawing the lithium will reverse both. Increasing the lithium dose or prescribing propylthiouracil will make this worse. Iodine supplements are not indicated.

Azithromycin is prescribed for a patient who develops an infection. The patient's only other medication is simvastatin. Which patient symptom will create the greatest concern for the provider?

• Nausea
• Tiredness
• Muscle pain

d. Headache - Correct Answer - ANS: C

Statins can injure muscle tissue, causing muscle aches and pain known as myopathy/rhabdomyolysis. Azithromycin also can cause myopathy and therefore should be used with caution in patients concurrently taking simvastatin. Nausea, tiredness, and headache would not cause the provider as much concern as the likelihood of myopathy.

What method will the provider consider the most reliable measure for assessing a patient's diabetes control over the preceding 3-month period?

• Self-monitoring blood glucose (SMBG) graph report
• Random blood glucose level 3 / 4

• | P a g e

pg. 4

• Fasting blood glucose level
• Glycosylated hemoglobin level (A1c) - Correct Answer - D

The glycosylated hemoglobin level tells much about what the plasma glucose concentration has been, on average, over the previous 2 to 3 months. The SMBG graph report is done by the patient and indicates each blood sugar level the patient has on a daily basis. It is not as reliable as the glycosylated hemoglobin level, because the equipment used might not be accurate and the testing may not reflect actual measurements 100% of the time. Random blood sugar levels are not as accurate as the glycosylated hemoglobin level for the same reason that the SMBG is not. One fasting blood glucose level indicates the patient's blood sugar level for that one time when it was obtained but is not reflective of a 3-month period.

Insulin glargine is prescribed by the provider for a hospitalized patient with type 1 diabetes. When will the provider order this medication to be administered?

• Approximately 15 to 30 minutes before each meal

b. In the morning and at 4:00 PM

• Once daily at bedtime
• After meals and at bedtime - Correct Answer - C

Glargine insulin is indicated for once-daily subcutaneous administration to treat adults and children with type 1 diabetes and adults with type 2 diabetes. According to the package labeling, the once-daily injection should be given at bedtime.Glargine insulin should not be given more than once a day, although some patients require bid dosing to achieve a full 24 hours of basal coverage.

A patient arrives in the emergency department with a heart rate of 128 beats/minute & a temperature of 105°F. The patient's skin feels hot & moist. The free T4 level is

• ng/dL, the free T3 level is 685 pg/dL, & the TSH level is 0.1 microunits/mL. The

provider caring for this patient will give what intervention priority?

• Intravenous levothyroxine
• Iodine-131 (131I)
