This is a contraindication in this patient population and should not be given.

 This benefit outweighs the risk, and the medication should be given.

 An alternative medication of the same class should be prescribed for safety .

 None of the above.

 Penicillin G

Question 8A mother has called because her 4-year-old has a fever of 102.2 F. She thinks it could be an ear infection based on the child’s symptoms and complaints of ear pain. With your understanding of bioavailability of drugs, you advize mom to give which medication?

Ibuprofen chewable tablets

 Ibuprofen liquid

 Ibuprofen tablets

 Tylenol chewable tablets.

Question 9Anthelmintic agents act in what areas?

Systemically and locally

 Systemically

 Locally

 Topically

Question 10You are prescribing a medication to a patient with impaired liver function. Given what you know about first pass effect, what form of administration would you avoid?

Oral

 Topical

 Inhalation

 Parenteral

Question 11At what age will the isoenzyme activities reach a level of function equivalent to an adult?

 6 months

 1-2 years

 3-4 years

 5-7 years

 Question 12Systemic fungal infections include histoplasmosis, coccidioidomycosis, cryptococcosis, blastomycosis and sporotrichosis. This is most often contracted through which method?

Topical

 Inhalation

 Oral

 Nosocomial transmission

 Question 13Polyenes have what mechanism of action against fungal infections?

 Bind to sterols in the fungal cell

 Bind to protein in the fungal cell

 Bind to host cell wall to prevent fungal infection

 Bind to host cell protein to prevent fungal infection

Question 14 Enterobiasis is caused by a small threadlike pinworm. The treatment of choice in this condition is which of the following?

 Ivermectin

 Two doses of Pyrantel

 Single dose of albendazole

 No medication is needed just supportive care

Question 15You are evaluating a 84 year old patient for hyperlipidemia. You are considering prescribing Lipitor. When considering this, what should you evaluate for safe prescribing?

Modification of Diet in Renal Disease

 Cockcroft-Gault formula

 The patient’s serum creatinine rounded up to 1 mg/dl

 All of the above

Question 16What is considered to be the primary determinant of drug pharmacokinetics and pharmacodynamics?

Genetics

 Absorption

 Binding affinity

 Dosing form

Question 17Protein binding drugs tend to have what impact on the neonate and infant?

Be reduced in the body

 Be increased in the body

 Have the same plasma concentration as an adult

 Have a decreased steady state

Question 18Drug concentration is significant in patient care and medical management. This is best assessed when a drug has reached a steady state. What is your understanding of steady state of a drug?

It is the balance between absorption and elimination.

 It is the balance between the peak and trough.

 It is the balance between binding affinity and volume distribution.

 It is the balance between extraction ratio and administration rate.

Question 19A patient is taking a drug with a high binding affinity for albumin. Another drug that has a higher protein bound affinity is added to the patient's medication regime. What would be a possible outcome to monitor for?

The first drug may achieve toxic levels in the body.

 The second drug may achieve toxic levels in the body.

 Both drugs will achieve toxic levels in the body.

 Both drugs will work effectively.

Question 20You are caring for a patient with hypertension. You recently prescribed Metoprolol 25 mg tablets.  The patient has come back to see you today and complains of constipation after starting this drug. What type of adverse reaction is this classified as?

Type A

 Type B

 Type C

 Type D

Question 21A number of demographic variables are associated with differences in in drug metabolism. Which of the following is not considered one of those differences?

Males metabolize more efficiently than females.

 Older adults metabolize drugs less efficiently than younger adults.

 Females metabolize more efficiently than males.

 Poor metabolizers may experience exaggerated side effects.
